Abstract
PURPOSE This evidence-based systematic review with meta-analysis aims to synthesize the inferior mesenteric artery (IMA) variants including their origin level, branching patterns, and morphometric characteristics. MATERIALS AND METHODS The study adhered to the latest guidelines. Four online databases were used for the systematic review, and studies that reported the prevalence of IMA variants were considered eligible for inclusion. A statistical meta-analysis was conducted using R programming software with a random-effects model to calculate the pooled prevalence of the variants. RESULTS Twenty-three (23) studies were included in this analysis. The IMA typically originated at the 3rd lumbar vertebra (L3) level, occurring in 70.16% of cases. The most common branching pattern of the IMA was bifurcated, indicating a pooled prevalence of 63.89%. This predominant pattern involved the IMA bifurcating into the left colic artery (LCA) and a common trunk for both the superior rectal artery (SRA) and the sigmoid artery (SA), with a pooled prevalence of 46.09%. The IMA trifurcation and tetrafurcation had pooled prevalences of 27.35% and 11.62%, respectively. The diameter of the IMA had a pooled mean of 41.41 mm, and the distance from the IMA's origin to the LCA had a pooled mean of 40.67 mm. CONCLUSIONS This review of existing literature delineates the IMA levels of origin, branching patterns, and morphometric characteristics. A comprehensive understanding of the surgical anatomy of this vessel is imperative during colorectal cancer procedures. Consequently, surgeons operating in this anatomical region must possess an in-depth knowledge of typical and variant anatomical structures.

Preoperative angio-CT colonography improves the quality of lymph node dissection during minimally invasive right hemicolectomy: a propensity score-matched study. Surg Endosc 2025; 39:3247-3258. [PMID: 40229597 DOI: 10.1007/s00464-025-11649-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2024] [Accepted: 03/02/2025] [Indexed: 04/16/2025]
Abstract
BACKGROUND Minimally invasive right hemicolectomy for cancer with complete mesocolic excision is a difficult procedure to perform. The aim of this single-center prospective study was to evaluate whether preoperative angio-CT colonography (A-CTC) improved the quality of lymph node dissection during this surgery. METHODS All patients undergoing elective minimally invasive right hemicolectomy for colon adenocarcinoma with complete mesocolic excision between 01/2020 and 12/2023 have been prospectively included. The primary endpoint was the number of lymph nodes examined in the surgical specimen, including the total number of lymph nodes and the percentage of patients with at least 12 lymph nodes examined. Secondary endpoints included operating time, intraoperative complications, overall postoperative morbidity, and length of hospital stay. A propensity score was constructed with groups matched 3:1 using nearest neighbor matching based on the propensity score. RESULTS Of the 161 patients included, 44 had A-CTC (27%) and 117 had conventional CT scans. After propensity score matching, patients in the A-CTC group had significantly more lymph nodes on the surgical specimen (24 vs. 20, p = 0.006) and a better quality of lymph node dissection (≥ 12 examined lymph nodes: 100% vs. 87%, p < 0.001). Median operative times were similar between the two groups (184 vs. 180 min, p = 0.07), but two patients (2%) in the conventional CT group experienced an intraoperative bleeding complication. Postoperative morbidity and length of hospital stay were comparable. CONCLUSIONS Preoperative 3D reconstruction of vascular anatomy with A-CTC is useful and improves the quality of lymph node dissection during minimally invasive right hemicolectomy for cancer.

Abstract
The inferior mesenteric artery (IMA) and inferior mesenteric vein (IMV) supply and drain blood from the distal colon and rectum, respectively. Routinely imaged at cross-sectional imaging of the abdomen and pelvis, these vessels play a vital role in gastrointestinal tract health but may be neglected due to their diminutive caliber relative to other mesenteric vessels and potential lack of inclusion in routine search patterns. The authors describe and illustrate normal and abnormal appearances of the IMA and IMV and findings that are diagnostic of primary vascular abnormalities or can offer diagnostic clues. After the embryologic features, normal anatomy, and anatomic variants of the IMA and IMV are reviewed, various manifestations of IMA and IMV abnormalities, such as aneurysm and pseudoaneurysm, stenosis, occlusion, dissection, hemorrhage, arteriovenous malformations and fistulas, tumoral invasion, vasculitis, and perivascular lymphatic dilatation, are explored with use of case examples. The role of the IMA and IMV as collateral vasculature, including the clinical scenarios of superior mesenteric arterial occlusion, aortic endoleak, and portosystemic venous shunt, are discussed. Finally, diagnostic clues that the inferior mesenteric vessels and adjacent soft tissues can provide, including mesenteric venous gas, compression or displacement from bowel volvulus or internal hernias, lymphadenopathy, and venous flow artifacts, are highlighted. The authors provide a comprehensive reference for radiologists who evaluate the IMA and IMV on cross-sectional images and shine a spotlight on these neglected but important vessels. ©RSNA, 2024 Supplemental material is available for this article.

[PMID: 39575297 PMCID: PMC11577405 DOI: 10.4240/wjgs.v16.i10.3104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2024] [Revised: 08/29/2024] [Accepted: 09/12/2024] [Indexed: 09/27/2024] Open
Abstract
BACKGROUND Prior studies have shown that preserving the left colic artery (LCA) during laparoscopic radical resection for rectal cancer (RC) can reduce the occurrence of anastomotic leakage (AL), without compromising oncological outcomes. However, anatomical variations in the branches of the inferior mesenteric artery (IMA) and LCA present significant surgical challenges. In this study, we present our novel three dimensional (3D) printed IMA model designed to facilitate preoperative rehearsal and intraoperative navigation to analyze its impact on surgical safety. AIM To investigate the effect of 3D IMA models on preserving the LCA during RC surgery. METHODS We retrospectively collected clinical dates from patients with RC who underwent laparoscopic radical resection from January 2022 to May 2024 at Fuyang People's Hospital. Patients were divided into the 3D printing and control groups for statistical analysis of perioperative characteristics. RESULTS The 3D printing observation group comprised of 72 patients, while the control group comprised 68 patients. The operation time (174.5 ± 38.2 minutes vs 198.5 ± 49.6 minutes, P = 0.002), intraoperative blood loss (43.9 ± 31.3 mL vs 58.2 ± 30.8 mL, P = 0.005), duration of hospitalization (13.1 ± 3.1 days vs 15.9 ± 5.6 days, P < 0.001), postoperative recovery time (8.6 ± 2.6 days vs 10.5 ± 4.9 days, P = 0.007), and the postoperative complication rate (P < 0.05) were all significantly lower in the observation group. CONCLUSION Utilization of a 3D-printed IMA model in laparoscopic radical resection of RC can assist surgeons in understanding the LCA anatomy preoperatively, thereby reducing intraoperative bleeding and shortening operating time, demonstrating better clinical application potential.

World J Gastrointest Surg 2024; 16:1548-1557. [PMID: 38983331 PMCID: PMC11230005 DOI: 10.4240/wjgs.v16.i6.1548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/13/2024] [Accepted: 05/22/2024] [Indexed: 06/27/2024] Open
Abstract
BACKGROUND Laparoscopic low anterior resection (LLAR) has become a mainstream surgical method for the treatment of colorectal cancer, which has shown many advantages in the aspects of surgical trauma and postoperative rehabilitation. However, the effect of surgery on patients' left coronary artery and its vascular reconstruction have not been deeply discussed. With the development of medical imaging technology, 3D vascular reconstruction has become an effective means to evaluate the curative effect of surgery. AIM To investigate the clinical value of preoperative 3D vascular reconstruction in LLAR of rectal cancer with the left colic artery (LCA) preserved. METHODS A retrospective cohort study was performed to analyze the clinical data of 146 patients who underwent LLAR for rectal cancer with LCA preservation from January to December 2023 in our hospital. All patients underwent LLAR of rectal cancer with the LCA preserved, and the intraoperative and postoperative data were complete. The patients were divided into a reconstruction group (72 patients) and a nonreconstruction group (74 patients) according to whether 3D vascular reconstruction was performed before surgery. The clinical features, operation conditions, complications, pathological results and postoperative recovery of the two groups were collected and compared. RESULTS A total of 146 patients with rectal cancer were included in the study, including 72 patients in the reconstruction group and 74 patients in the nonreconstruction group. There were 47 males and 25 females in the reconstruction group, aged (59.75 ± 6.2) years, with a body mass index (BMI) (24.1 ± 2.2) kg/m2, and 51 males and 23 females in the nonreconstruction group, aged (58.77 ± 6.1) years, with a BMI (23.6 ± 2.7) kg/m2. There was no significant difference in the baseline data between the two groups (P > 0.05). In the submesenteric artery reconstruction group, 35 patients were type I, 25 patients were type II, 11 patients were type III, and 1 patient was type IV. There were 37 type I patients, 24 type II patients, 12 type III patients, and 1 type IV patient in the nonreconstruction group. There was no significant difference in arterial typing between the two groups (P > 0.05). The operation time of the reconstruction group was 162.2 ± 10.8 min, and that of the nonreconstruction group was 197.9 ± 19.1 min. Compared with that of the reconstruction group, the operation time of the two groups was shorter, and the difference was statistically significant (t = 13.840, P < 0.05). The amount of intraoperative blood loss was 30.4 ± 20.0 mL in the reconstruction group and 61.2 ± 26.4 mL in the nonreconstruction group. The amount of blood loss in the reconstruction group was less than that in the control group, and the difference was statistically significant (t = -7.930, P < 0.05). The rates of anastomotic leakage (1.4% vs 1.4%, P = 0.984), anastomotic hemorrhage (2.8% vs 4.1%, P = 0.672), and postoperative hospital stay (6.8 ± 0.7 d vs 7.0 ± 0.7 d, P = 0.141) were not significantly different between the two groups. CONCLUSION Preoperative 3D vascular reconstruction technology can shorten the operation time and reduce the amount of intraoperative blood loss. Preoperative 3D vascular reconstruction is recommended to provide an intraoperative reference for laparoscopic low anterior resection with LCA preservation.

Abstract
The incidence of esophagogastric junction cancer has been increasing, leading to growing interest in surgical treatment. Leriche syndrome, characterized by occlusion limited to the infrarenal aorta, has not been reported to be associated with ischemic enteritis, and there are no previous reports on the surgical approaches for esophagogastric junction cancer in this disease.We describe the case of a male patient in his fifties with lower abdominal pain and melena who was diagnosed with esophagogastric junction cancer, Leriche syndrome, and ischemic enteritis. Contrast-enhanced computed tomography (CT) showed a hemorrhage from the cancer, occlusion of the abdominal aorta beyond the renal artery branches, and rectal contrast deficiency. Three-dimensional (3D)-CT angiography revealed occlusion from the lumbar artery bifurcation to the distal portions of both common iliac arteries plus numerous collateral pathways, indicating a precarious rectal blood supply. Based on 3D-CT angiography, minimally invasive surgery (MIS) using laparoscopy and thoracoscopy for esophagogastric junction cancer was performed after whole-body control. The patient was discharged without any postoperative complications.Esophagogastric junction cancer with Leriche syndrome can be complicated by ischemic enteritis due to tumor bleeding and fragile collateral pathways. MIS using laparoscopy and thoracoscopy guided by 3D-CT angiography can be safely performed for this disease.

Abstract
To assess the anatomy of the inferior mesenteric artery (IMA) and its branches by reviewing laparoscopic left-sided colorectal cancer surgery videos and comparing them with preoperative three-dimensional computed tomography (3D-CT) angiography, to verify the accuracy of 3D-CT vascular reconstruction techniques. High-definition surgical videos and preoperative imaging data of 200 patients who underwent laparoscopic left-sided colorectal cancer surgery were analysed, and the alignment of the IMA and its branches in relation to the inferior mesenteric vein (IMV) was observed and summarized. The above two methods were used to measure the length of the IMA and its branches. Of 200 patients, 47.0% had the sigmoid arteries (SAs) arise from the common trunk with the superior rectal artery (SRA), and 30.5% had the SAs arise from the common trunk with the left colic artery (LCA). In 3.5% of patients, the SAs arising from both the LCA and SRA. The LCA, SA, and SRA emanated from the same point in 13.5% of patients, and the LCA was absent in 5.5% of patients. The range of D cm (IMA length measured by intraoperative silk thread) and d cm (IMA length measured by 3D-CT vascular reconstruction) in all cases was 1.84-6.62 cm and 1.85-6.52 cm, respectively, and there was a significant difference between them. (p < 0.001). The lengths between the intersection of the LCA and IMV measured intraoperatively were 0.64-4.29 cm, 0.87-4.35 cm, 1.32-4.28 cm and 1.65-3.69 cm in types 1A, 1B, 1C, and 2, respectively, and there was no significant difference between the groups (p = 0.994). There was only a significant difference in the length of the IMA between the 3D-CT vascular reconstruction and intraoperative observation data, which can provide guidance to surgeons in preoperative preparation.

Abstract
Objectives This study aims to investigate the surgical anatomy and clinical variation of the left colonic artery (LCA) during laparoscopic anterior rectal resection. Methods We conducted a retrospective analysis of 87 patients diagnosed with colorectal cancer who underwent laparoscopic anterior rectal resection with preserved LCA at the Department of Gastroenterology, Sichuan Cancer Hospital, between March 2018 and April 2022, aiming to observe the emanation location, anatomical typing, and travel trajectory of the LCA, as well as its relationship with the inferior mesenteric vein (IMV). Results In all observed cases, we observed that the LCA emanated from the left side of the inferior mesenteric artery (IMA), and the average distance from the root of the IMA to the emanation of the LCA was approximately 3.5 ± 1.1 cm. Specifically, 35 of these cases had the LCA branching from the IMA alone (Type I, 40.2%),16 cases had the LCA cotruncating with the sigmoid artery (SA) (Type II, 18.4%), 30 cases had the LCA cotruncating with the superior rectal artery (SRA) and SA (Type III, 34.5%), and six cases had the LCA cotruncating with four or more branches of the SRA and SA (Type IV, 6.9%). No LCA agenesis cases were found in this group. In addition, we also observed the occurrence of LCA alignment. Specifically, there were 25 cases where the LCA crossed the IMV in a diagonal upward direction (Type A, 28.7%), 36 cases where the LCA crossed the IMV in an upward arched manner (Type B, 41.4%), 18 cases where the LCA crossed the IMV in a vertical outward direction (Type C, 20.7%), and eight cases where the LCA crossed the IMV in a diagonal downward manner (Type D, 9.2%). Among them, two cases developed anastomotic fistula, one case had chyle leakage 1 week after surgery, and four cases experienced urinary retention; all of the patients successfully recovered and were discharged after receiving conservative treatment. Conclusion The anatomy and variation of the LCA can be clearly and accurately observed during laparoscopic surgery. Understanding the type and variation of the LCA helps to dissect the vessels in the IMA region during surgery, particularly in cases when the LCA is preserved, and reduce the incidence of vascular injury and its complications.

Abstract
Objective To determine the branching patterns of the inferior mesenteric artery (IMA) and to describe the clinical applicability of computed tomography (CT) angiography in the evaluation of these vessels to facilitate the planning of colorectal cancer surgery. Materials and Methods We included 100 patients who underwent CT angiography of the abdomen and pelvis. The branching patterns of the IMA were examined and classified as type 1 (bifurcated), including 1A (sigmoid and left colic arteries arising from a common trunk), 1B (sigmoid and superior rectal arteries arising from a common trunk) and 1C (sigmoid arteries arising from both trunks); type 2 (trifurcated); and type 3 (no left colic branch). Results Among the 100 patients evaluated, we found the variant to be type 1A in 9%, type 1B in 47%, type 1C in 24%, type 2 in 16%, and type 3 in 4%. Conclusion Preoperative CT angiography for evaluating the IMA branching pattern could inform decisions regarding the surgical approach to colorectal cancer.

Inferior Mesenteric Artery Ligation Level in Rectal Cancer Surgery beyond Conventions: A Review. Cancers (Basel) 2023; 16:72.

Abstract
Within the intricate field of rectal cancer surgery, the contentious debate over the optimal level of ligation of the inferior mesenteric artery (IMA) persists as an ongoing discussion, influencing surgical approaches and patient outcomes. This narrative review incorporates historical perspectives, technical considerations, and functional as well as oncological outcomes, addressing key questions related to anastomotic leakage risks, genitourinary function, and oncological concerns, providing a more critical understanding of the well-known inconclusive evidence. Beyond the dichotomy of high versus low tie, it navigates the complexities of colorectal cancer surgery with a fresh perspective, posing a transformative question: "Is low tie ligation truly reproducible?" Considering a multidimensional approach that enhances patient outcomes by integrating the surgeon, patient, technique, and technology, instead of a rigid and categorical statement, we argued that a balanced response to this challenging question may require compromise.

Abstract
AIM The splenic flexure has variable vascular anatomy, and the details of the venous forms are not known. In this study, we report the flow pattern of the splenic flexure vein (SFV) and the positional relationship between the SFV and arteries such as the accessory middle colic artery (AMCA). METHODS This was a single-centre study using preoperative enhanced CT colonography images of 600 colorectal surgery patients. CT images were reconstructed into 3D angiography. SFV was defined as a vein flowing centrally from the marginal vein of the splenic flexure visible on CT. AMCA was defined as the artery feeding the left side of the transverse colon, separate from the left branch of the middle colic artery. RESULTS The SFV returned to the inferior mesenteric vein (IMV) in 494 cases (82.3%), the superior mesenteric vein in 51 cases (8.5%) and the splenic vein in seven cases (1.2%). The AMCA was present in 244 cases (40.7%). The AMCA branched from the superior mesenteric artery or its branches in 227 cases (93.0% of cases with existing AMCA). In the 552 cases in which the SFV returned to the IMV, superior mesenteric vein or splenic vein, the left colic artery was the most frequent artery accompanying the SFV (42.2%), followed by the AMCA (38.1%) and the left branch of the middle colic artery (14.3%). CONCLUSIONS The most common flow pattern of the vein in the splenic flexure is from the SFV to IMV. The SFV is frequently accompanied by the left colic artery or AMCA.

Abstract
INTRODUCTION We aimed to investigate manual subtraction computed tomography angiography (MS-CTA) to further confirm the distribution and classification of LCA (left colic artery) ascending/descending branches, then observe the postoperative blood flow path to illustrate how the above branches evolved to postoperative blood path. MATERIAL AND METHODS 89 patients with distal sigmoid and rectal cancer were referred in our observation and underwent MS-CTA between June 2020 and March 2022. We classified the distribution of LCA and confirmed whether there exists AMCA (accessory middle colic artery). Then we planned blood flow path based on the classification of LCA branches before operation. High ligation was applied in regular radical surgery. During operation, we carefully protect the bifurcation of ascending and descending LCA. Then we compared the planned blood flow path with the actual postoperative blood flow path to verify the mechanism we proposed previously. RESULTS Of 89 patients, 82 cases met our criteria, we summarized 6 distribution pattens of LCA ascending and descending branches. These preoperative pattens are consistent with the inspection during operation. The postoperative blood flow path of 6 pattens is evolved from the above adjacent anastomotic branches and is consistent with the planned blood flow path. We also found 2 cases with IMA stenosis and 1 case with SMA stenosis under pathological condition, and their compensatory blood flow path is in accordance with our theory. The rate of the anastomotic leakage in our study group is relatively low (7.3%). CONCLUSION MS-CTA could confirm the distribution of LCA and AMCA, display accurate postoperative blood reconstruction path after IMA high ligation, and it further verified the mechanism we proposed previously, which is the proximal anastomotic branches forming new blood flow path from high-pressure area to the low-pressure area. This mechanism might be helpful for performing accurate laparoscopic sigmoid and rectal cancer surgery.

Abstract
BACKGROUND We mainly evaluated whether preserving the inferior mesenteric artery (IMA) sheath to dissecting IMA root lymph nodes (also called No.253 lymph nodes) would benefit patients in terms of comparable lymph-node yield removed during operation and postoperative complications in laparoscopic radical resection of rectal cancer. METHODS This is a prospective study included 141 rectal cancer patients who received laparoscopic radical resection during September 2018 to December 2020. All patients were randomly assigned to the preserved group (n = 71) and the peeled group (n = 70). The baseline characteristics, pathological features, intraoperative and postoperative data outcomes and complications were analyzed by independent samples t test, chi-square test or Fisher's exact test between the 2 groups. RESULTS The baseline characteristic and pathological features had no statistical difference between the 2 groups. The preserved group had a shorter operative time (P = 0.002), a shorter lymph node dissection time (P < 0.001), less intraoperative bleeding (P = 0.004), an earlier time to first flatus (P = 0.013), an earlier time to fluid intake (P = 0.033) and a shorter length of hospitalization (P = 0.012) than the peeled group. The differences between the 2 groups were not statistically significant (P > 0.05) in regard to the total number of lymph nodes cleared, positive lymph nodes, bleeding, anastomotic leakage, pneumonia, wound infection, abscess, ileus, urinary retention, urinary tract infection and chyle leakage. CONCLUSION Preserving of the IMA sheath in laparoscopic radical surgery for rectal cancer will reduce the total operation time and the length of hospitalization. This surgical method could lead to lower complication rate and faster recovery. TRIAL REGISTRATION The study was approved by the Ethics Committee of The First Affiliated Hospital of Wannan Medical College and registered by the China Clinical Trials Registry (ChiCTR2200060830, Date of Registration:2022-06-12 -retrospective registration) http://www.chictr.org.cn/index.aspx .

Abstract
PURPOSE Direct connection between the celiac trunk (CT) and inferior mesenteric artery (IMA) is very rare, knowledge of this anomaly is of great importance to surgeons and anatomists. INTRODUCTION Splanchnic arteries arise from the abdominal aorta (AA). Unusual development of these arteries can lead to considerable variations. Historically there were a lot of classification of the variation in the CT and IMA, none of the classifications describes a direct connection from IMA to CT. MATERIALS AND METHODS We report a rare case in which the connection between the CT and AA was lost and replaced by a direct anastomosis with IMA. RESULTS 60 year old male presented to the hospital to undergo a computed tomography scan. Which showed that there was no CT arising from the AA, but there was a large anastomosis arises from the IMA and ended with a short axis and Left gastric artery (LGA), Splenic artery (SA), Common hepatic artery (CHA) arise from this axis, these arteries continued to the stomach and spleen and liver normally. The anastomosis provides the total supply to the CT. The CT branches are normal. CONCLUSION Knowledge of the arterial anomalies provides an important help in clinical surgical implications especially in organs transplant.

Abstract
BACKGROUND Laparoscopic and robotic surgery for transverse colon cancer are difficult due to complex fusion of the foregut and midgut and variation of the vessels of the transverse colon. Although the vessels of the right colon have been investigated, middle colic artery (MCA) variation and the relationship with vessels around the transvers colon are unknown. We investigated variation of the MCA using computed tomography angiography (CTA) and cadaver specimen and the relationship between the superior mesenteric vein (SMV) and MCA using CTA. The classification of vessels around the transverse colon may lead to safer and reliable surgery. METHODS This study included 505 consecutive patients who underwent CTA in our institution from 2014 to 2020 and 44 cadaver specimens. Vascular anatomical classifications and relationships were analyzed using CT images. RESULTS The MCA was defined as the arteries arising from the superior mesenteric artery (SMA) that flowed into the transverse colon at the distal ends. The classifications were as follows: type I, branching right and left from common trunk; type II, the right and left branches bifurcated separately from the SMA; and type III, the MCA branched from a vessel other than the SMA. Type II was subclassified into two subtypes, type IIa with one left branch and type IIb with two or more left branches from SMA. In the CTA and cadaver studies, respectively, the classifications were as follows: type I, n = 290 and n = 31; type IIa, n = 211 and n = 13; type IIb, n = 3 and n = 0; and type III, n = 1 and n = 0. We classified the relationship between the MCA and left side of the SMV into three types: type A, a common trunk runs along the left edge of the SMV (n = 173; 59.7%); type B, a right branch of the MCA runs along the left edge of the SMV (n = 116; 40.0%); and type C, the MCA runs dorsal of the SMV (n = 1; 0.3%). CONCLUSIONS This study revealed that The MCA branching classifications and relationship between the SMV and MCA. Preoperative CT angiography may be able to reliably identify vessel variation, which may be useful in clinical practice.

Re-interpreting mesenteric vascular anatomy on 3D virtual and/or physical models, part II: anatomy of relevance to surgeons operating splenic flexure cancer. Surg Endosc 2022; 36:9136-9145. [PMID: 35773607 PMCID: PMC9652173 DOI: 10.1007/s00464-022-09394-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Accepted: 06/06/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND The splenic flexure is irrigated from two vascular areas, both from the middle colic and the left colic artery. The challenge for the surgeon is to connect these two vascular areas in an oncological safe procedure. MATERIALS AND METHODS The vascular anatomy, manually 3D reconstructed from 32 preoperative high-resolution CT datasets using Osirix MD, Mimics Medical and 3-matic Medical Datasets, were exported as STL-files, video clips, stills and supplemented with 3D printed models. RESULTS Our first major finding was the difference in level between the middle colic and the inferior mesenteric artery origins. We have named this relationship a mesenteric inter-arterial stair. The middle colic artery origin could be found cranial (median 3.38 cm) or caudal (median 0.58 cm) to the inferior mesenteric artery. The lateral distance between the two origins was 2.63 cm (median), and the straight distance 4.23 cm (median). The second finding was the different trajectories and confluence pattern of the inferior mesenteric vein. This vein ended in the superior mesenteric/jejunal vein (21 patients) or in the splenic vein (11 patients). The inferior mesenteric vein confluence could be infrapancreatic (17 patients), infrapancreatic with retropancreatic arch (7 patients) or retropancreatic (8 patients). Lastly, the accessory middle colic artery was present in ten patients presenting another pathway for lymphatic dissemination. CONCLUSION The IMV trajectory when accessible, is the solution to the mesenteric inter-arterial stair. The surgeon could safely follow the IMV to its confluence. When the IMV trajectory is not accessible, the surgeon could follow the caudal border of the pancreas.

Abstract
BACKGROUND Anastomotic blood supply is vital to anastomotic healing. The aim of this study was to demonstrate the effect of the left colic artery (LCA) on blood supply in the anastomotic area, explore the relationship between individual differences in the LCA and blood supply in the anastomotic area, and elucidate the relevant indications for LCA retention during radical resection for sigmoid or rectal cancer. METHOD Radical sigmoid or rectal cancer resection with LCA retention was performed in 40 patients with colorectal cancer who participated in this study. Systemic pressure, LCA diameter, and the distance from the root of the LCA to the root of the inferior mesenteric artery were measured and recorded. The marginal artery stump pressure in the anastomotic colon before and after the LCA clamping was measured, respectively. RESULTS There is a significant difference between the marginal artery stump pressure before LCA ligation and after ligation (53.1 ± 12.38 vs 42.76 ± 12.71, p < 0.001). The anastomotic blood supply positively and linearly correlated with body mass index and systemic pressure. Receiver-operating curve analysis revealed that LCA diameter (area under the curve 0.971, cutoff 1.95 mm) was an effective predictor of LCA improving anastomosis blood supply. No relationship was found between the LCA root location and anastomotic blood supply. CONCLUSION Preserving the LCA is effective in improving blood supply in the anastomotic area, and larger LCA diameters result in a better blood supply to the anastomotic area.

World J Surg Oncol 2022; 20:290.

Abstract
Currently, high or low ligation of the inferior mesenteric artery (IMA) is a controversial issue in laparoscopic radical surgery for colorectal cancer. High or low ligation of the IMA has both advantages and disadvantages, and the level of ligation during the left colon and/or rectum resection has been a dilemma for surgeons. One important factor influencing the surgeon's decision to ligate the IMA in a high or low position is the anatomical type of the IMA and its branches. Some studies confirm that the anatomy of the IMA and its branches is critical to the anastomotic blood supply and, therefore, influences the choice of surgical approach (level of ligation of the IMA). However, many vascular variations in the anatomy of the IMA and its branches exist. Herein, we have summarized the anatomical types of the IMA and its branches, finding that the classification proposed by Yada et al. in 1997 is presently accepted by most scholars. Based on Yada's classification, we further summarized the characteristics of the IMA's various anatomical types as a guide for high or low ligation in radical colorectal cancer surgery.

Abstract
Background The aim of this prospective study was to determine the effect of mesenteric vascular evaluation using pre-operative multidetector computed tomography angiography (MDCTA) and intraoperative indocyanine green (ICG) angiography on reducing the anastomotic leak rate of colorectal cancer patients undergoing minimally invasive resection. Methods Twenty-seven consecutive patients with colorectal cancer were studied, 18 males and 9 females, average age 69.1 ± 3.9 years. All patients underwent pre-operative mesenteric vascular evaluation using MDCTA with three-dimensional (3D) reconstruction and intraoperative evaluation of perfusion using ICG angiography. Twelve patients underwent laparoscopic resection (Olympus Visera Elite II OTV-S200) and 15 patients underwent robotic resection (DaVinci Si). Colorectal resection lines and anastomoses were guided by intraoperative ICG perfusion. Postoperative anastomotic leaks were assessed. Results Pre-operative MDCTA 3D reconstructions defined the left colic and sigmoid artery anatomy and guided operative planning. The intraoperative ICG angiography resulted in a change of the planned lines of resection in seven patients (26%). The rate of postoperative anastomotic leaks in this study was 0% (0/27), compared to a leak rate of 6.8% at our institution in the preceding two years. Conclusion Pre-operative evaluation of mesenteric vascular anatomy using MDCTA with 3D reconstruction and intraoperative evaluation of perfusion using ICG angiography were found to be technically feasible and safe. An appropriately designed study should be undertaken to prove whether it was truly effective at reducing the postoperative anastomotic leak rate in colorectal cancer patients undergoing minimally invasive resection at our institution.

Abstract
AIM To assess the utility of preoperatively evaluating the vascular anatomy using multisection spiral computed tomography angiography (CTA) and image fusion technology in the treatment of obese patients undergoing laparoscopic radical resection for rectal cancer. MATERIALS AND METHODS This randomised prospective study included 56 patients who underwent laparoscopic surgery for rectal cancer. Patients were randomly divided into two groups: the fusion imaging group (preoperative CTA and image fusion reconstruction [n=28]) and the control group (not performed CTA and image fusion reconstruction before the operation [n=28]). Duration of surgery was defined as the primary endpoint, and the volume of bleeding, the number of lymph node dissections, conversion to laparotomy, time to recovery of postoperative flatus, length of hospitalisation as well as perioperative complications were defined as secondary endpoints. RESULTS Compared with the control group, the duration of surgery in the image fusion group was shorter, bleeding volume was reduced, and the number of lymph node dissections was greater (p<0.05); however, there was no significant differences between the two groups regarding time to postoperative flatus recovery, conversion to laparotomy, length of hospitalisation, and perioperative complications (p>0.05). CONCLUSIONS Preoperative assessment of the vascular anatomy was an effective method and avoided some invisible risks during surgery, and resulted in a better therapeutic effect.

Abstract
OBJECTIVES The objective of this study is to analyze the main patterns of branching of the inferior mesenteric artery (IMA) and to determine if your knowledge changes the surgical strategy in the colorectal cancer. METHODS This retrospective study included 63 patients with cancer of the sigmoid or rectum. We assessed the patterns of IMA in 3 subtypes: type A (independent left colic artery [LCA]), type B (LCA and sigmoid artery arising in a common trunk) and type C (LCA, sigmoid artery, and superior rectal artery with a common origin). Colorectal surgeons evaluated how the vascular map changed the type of IMA ligation. RESULTS Inferior mesenteric artery branching was classified as type A in 55.6% patients, type B in 23.8%, and type C in 20.6%. Knowledge of the vascular map changed the type of ligation from high to low in 20 of the 50 patients who were candidates for surgery. The change was possible in tumors located in the sigmoid colon and the rectosigmoid junction with the type A or B branching. CONCLUSIONS Preoperative Multidetector Computed Tomography angiography can define the pattern of IMA branching. Based on this information, a low ligation can be performed in tumors located in sigmoid colon and rectosigmoid junction with IMA branching types A and B.

Abstract
Background This study was aimed to explore the clinical application of dual-energy computed tomography (DECT) monoenergetic plus (mono+) imaging to evaluate anatomical variations in the inferior mesenteric artery (IMA). Methods The clinical and imaging data of 212 patients who had undergone total abdominal DECT were retrospectively analyzed. The post-processing mono+ technique was used to obtain 40-keV single-level images in the arterial phase. Three-dimensional reconstruction was performed to evaluate the relationship between the IMA root position and the spinal level, IMA length, and IMA branch type, as well as the position of the left colic artery (LCA) and inferior mesenteric vein (IMV) at the IMA root level. Results The IMA root was located at the L3 level in 78.3% of cases and at the L2/L3 level in 3.3%. The highest vertebral level of IMA origin was L2 (4.2%), and the lowest was L4 (7.1%). The distance from the IMA root to the level of the sacral promontory was 99.58 ± 13.07 mm, which increased with the elevation of the IMA root at the spinal level. Of the patients, 53.8% demonstrated Type I IMA, 23.1% Type II, 20.7% Type III, and 2.4% Type IV. The length of the IMA varied from 13.6 to 66.0 mm. 77.3% of the IMAs belonged to Type A, the adjacent type, and 22.7% to Type B, the distant type. Conclusion DECT mono+ can preoperatively evaluate the anatomical characteristics of the IMA and the positional relationship between the LCA and IMV at the IMA root level, which would help clinicians plan individualized surgery for patients.
DECT mono+ optimal energy level can preoperatively determine the position of the IMA root. DECT mono+ can preoperatively evaluate the anatomical characteristics of the IMA. DECT mono+ can preoperatively determine the positional relationship between the LCA and IMV at the IMA root level.

Abstract
BACKGROUND Widely implemented in clinical practice 3D-CT angiography allows to conduct the analysis of vascular anatomy at the preoperative stage. The aim of this study is to carry out a detailed analysis of variants of the anatomy of the LCA, its relationship with the surrounding structures and to study the nuances that may complicate and increase the time of D3 lymph node dissection with preservation of LCA. METHODS In this study, we included 103 patients with left sided colon and rectal cancer who underwent preoperative 3D-CT angiography. RESULTS According to Zebrowski classification at al., 8 most frequent variants of IMA branching patterns are allocated: type A - 35 (34%) patients, type B - 28 (27.2 %), type C - 3 (2.9 %), type D - 4 (3.9 %), type E - 7 (6.8 %), type F - 7 (6.8 %), type G - 6 (5.8 %), type H - 13 (12.6 %). The average distance from the root of the IMA to the branch of the LCA was 35.29 mm ± 10.18 mm (11-66 mm). There are 3 types of anatomical relationship between IMA-LCA-IMV system. Medial type was in 10 (9,7 %) cases, lateral in 64 (62.1%), distal in 29 (28.2%). LCA intersects with the IMV at a distance of 20.97 ± 13.59 mm (2-65) in patients with lateral and distal type. CONCLUSIONS Careful preoperative analysis of vascular anatomy will assess the difficulty of performing D3 lymph node dissection with LCA preservation, reduce the time during the operation to identify structures and develop a personalized strategy for the operation.

Exploring Central Vascular Anatomy With Axial Computed Tomography During Surgery for Sigmoid Colon and Rectal Cancer: New Insights Into the Anatomical Relationship Between the Inferior Mesenteric Artery and the Duodenum. Front Surg 2021; 8:785313. [PMID: 34966777 PMCID: PMC8710449 DOI: 10.3389/fsurg.2021.785313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 11/23/2021] [Indexed: 11/13/2022] Open
Abstract
Background: In some individuals, the inferior mesenteric artery (IMA) originates from the aorta above the lower edge of the duodenum. This anatomical feature has rarely been reported but may be important in guiding central vascular ligation and lymph node dissection in colorectal surgery. This retrospective study aimed to explore the anatomical relationship between the IMA and the duodenum and evaluate its potential impact on the efficacy of D3 lymph node dissection. Methods: A total of 439 patients undergoing laparoscopic colorectal surgery at the Department of General Surgery, Qilu Hospital of Shandong University, were retrospectively enrolled. Clinical data from axial computed tomography (CT) scans were collected and analysed. Results: In 27.69% of patients, the IMA originated at or above the lower edge of the duodenum (median distance: −8 mm). These patients were characterised by a shorter superior mesenteric artery to aortic bifurcation distance, a superiorly located IMA origin, and a greater distance between the IMA and both the left colic artery and the inferior mesenteric vein. The number of harvested lymph nodes was not significantly associated with the distance between the IMA and the duodenum (P = 0.858). Conclusions: Preoperative axial CT scans can provide a great deal of information regarding central vascular anatomy in the context of sigmoid colon and rectal cancer surgery. Nearly one-third of patients have the IMA originating at or above the duodenum. Whether this anatomical feature affects D3 lymph node dissection warrants further investigation.

Low Ligation Plus High Dissection Versus High Ligation of the Inferior Mesenteric Artery in Sigmoid Colon and Rectal Cancer Surgery: A Meta-Analysis. Front Oncol 2021; 11:774782. [PMID: 34858855 PMCID: PMC8632045 DOI: 10.3389/fonc.2021.774782] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 10/25/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Whether high or low ligation of the inferior mesenteric artery (IMA) is superior in surgery for rectal and sigmoid colon cancers remains controversial. Although several meta-analyses have been conducted, the level of lymph node clearance was poorly defined. We performed a meta-analysis comparing high and low ligation of the IMA for sigmoid colon and rectal cancers, with emphasis on high dissection of the lymph node at the IMA root in all the included studies. METHODS PubMed, MEDLINE, and EMBASE databases were searched to identify relevant articles published until 2020. The patient's perioperative and oncologic outcomes were analyzed. Statistical analysis was performed using the statistical software RevMan version 5.4. RESULTS A total of 17 studies, including four randomized controlled trials, published between 2011 and 2020 were selected. In total, 1,846 patients received low ligation of the IMA plus high dissection of lymph nodes (LL+HD), and 2,648 patients received high ligation of the IMA (HL). LL+HD was associated with low incidence of anastomotic leakage (p < 0.001), borderline long operative time (p = 0.06), and less yields of total lymph nodes (p = 0.03) but equivalent IMA root lymph nodes (p = 0.07); moreover, LL+HD exhibited non-inferior long-term oncological outcomes. CONCLUSION In comparison with HL, LL+HD was an effective and safe oncological procedure for sigmoid colon and rectal cancers. Therefore, to ligate the IMA below the level of the left colic artery with D3 high dissection for sigmoid colon and rectal cancers might be suggested once the surgeons are familiar with this technique.

Abstract
PURPOSE To investigate the drainage patterns of the inferior mesenteric vein (IMV) and measure the distance from the root of the inferior mesenteric artery (IMA) to the IMV using preoperative three-dimensional computed tomography (3D-CT) angiography in patients undergoing surgery for left-sided colorectal cancer. METHODS In this retrospective study, we analyzed data collected prospectively on 167 consecutive patients who underwent laparoscopic left-sided colorectal cancer surgery between July, 2014 and August, 2019. The drainage pattern of the IMV and the distance from the root of the IMA to the IMV were evaluated using 3D-CT angiography. We also assessed intraoperative adverse events and postoperative outcomes. RESULTS The IMV drained into the superior mesenteric vein (SMV) in 44 patients, into the confluence point of the SMV and splenic vein (SV) in 38 patients, into the SV in 83 patients, and into the middle colic vein in the remaining three patients. The median length from the root of the IMA to the IMV was 22.1 mm (1.3-84.9). IMV injury occurred in only one patient during surgery, but resulted in colonic ischemia. CONCLUSION 3D-CT angiography is useful for the preoperative assessment of vascular anatomical variations of the IMV and IMA for safe intraoperative navigation and prevention of complications during laparoscopy-assisted left-sided colorectal surgery.

Abstract
Surgical treatment of the transverse colon is difficult because of the many variations of blood vessels. We reviewed the patterns of vascular anatomy and the definition of the vessels around the splenic flexure. We searched the PubMed database for studies on the vascular anatomy of the splenic flexure that were published from January 1990 to October 2020. After screening of full texts, 33 studies were selected. The middle colic arteries were reported to arise independently without forming a common trunk in 8.9-33.3% of cases. The left colic artery was absent in 0-7.5% of cases. The accessory middle colic artery was present in 6.7-48.9% of cases and was present in > 80% of cases without a left colic artery. The reported frequency of Riolan's arch was 7.5-27.8%. The frequency was found to vary widely across studies, partially due to the ambiguous definition of Riolan's arch. A comprehensive preoperative knowledge of the branching patterns of the middle colic artery and left colic artery and the presence of collateral arteries would be helpful in surgery for colon cancer in the splenic flexure.

Abstract
PURPOSE The descending branch of the left colic artery (dLCA) is under-recognized and has not been clearly defined. The dLCA is often confused with the sigmoid artery (SA) originating from the left colic artery (LCA). We clarified the anatomical characteristics of the dLCA and searched for surrogate measures to identify it. METHODS Arterial phase, venous phase, and three-dimensional images of abdominal arteries were created in 411 patients using contrast-enhanced computed tomography (CT). We analyzed the branching patterns of the inferior mesenteric artery (IMA) based on CT. The dLCA was defined as the artery originating from the LCA that flows into the marginal artery along the descending colon. We tested three candidate diagnostic measures for the dLCA using positional relationships and the segment length of vessels. RESULTS Arteries from the LCA were present in 360 patients, among which 459 dLCAs and 165 SAs were identified in 333 and 146, respectively. By the first measure of identifying the artery with its root lateral to the inferior mesenteric vein (IMV) as the dLCA, the sensitivity, specificity, and accuracy rate were 94%, 87%, and 92%, respectively. The second measure of identifying the artery with its root higher than the root of the IMA as the dLCA and the third of identifying the artery with its root located > 27.6 mm from the root of LCA as the dLCA yielded lower accuracy rates (69% and 89%, respectively). CONCLUSION Our study demonstrated that dLCAs are prevalent (93%) and may be easily found lateral to the IMV in clinical practice.

Abstract
AIM The aim of this study was to evaluate the arterial collateral vasculature between the superior mesenteric artery and the inferior mesenteric artery (IMA) from a surgical perspective. METHOD A total of 107 fresh adult cadavers (94 male) were studied with emphasis on the vascular anatomy of the left colon. Dissections were carried out mimicking the anterior resection technique. The vasculature of the left mesocolon and the collaterals between the superior mesenteric artery and the IMA with respect to their relationship to the inferior mesenteric vein (IMV) were assessed and classified. Collaterals were classified into three different groups: marginal anastomoses (via the marginal = pericolic artery), intermediate mesocolic anastomoses (parallel to the marginal artery but neither adjacent to the IMV nor close to the duodenum) and central mesocolic anastomoses (next to the IMV at the level of the duodenojejunal junction and the lower border of the pancreas). RESULTS All patients had a marginal anastomosis. However, the marginal anastomosis, as the only anastomosis between the superior and inferior mesenteric arteries at the splenic flexure, was observed in 41 cases (38%). In addition to the marginal artery, intermediate mesocolic anastomoses were found in 49 (46%) and a central mesocolic anastomosis was observed in 17 (16%) of the 107 cases in the splenic flexure mesocolon. It is in this latter variant that collateral vessels can be compromised during ligation/transection of the IMV. CONCLUSION This new classification can contribute to a precise mesocolic dissection technique and splenic flexure mobilization and help prevent ischaemic damage to the descending colon.

Abstract
INTRODUCTION The collateral pathways between the superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) play an important role in colonic surgery. The most well-known are the Drummond marginal artery and Riolan's arch. The Moskowitz artery, also known as the meandering mesenteric artery, is a lesser-known collateral pathway and represents another link between SMA and IMA. The Moskowitz artery runs along the colonic mesentery floor and represents the link between the proximal segment of the middle colic artery and the ascending branch of the left colic artery. AIM To comprehend the presence and importance of the Moskowitz artery (meandering mesenteric artery) in preoperative patients by using computed tomography (CT) studies. MATERIAL AND METHODS We retrospectively reviewed all abdominal CT images performed using intravenous contrast for any reason at the Radiology Department of Yeditepe University Hospital between April 2015 and September 2018. Patients older than 18 years with intravenous contrast (arterial and venous phases with a cross-section thickness of 0.625 mm), who underwent abdominal CT scan, and patients without any abdominal surgery were included in the study. As a result of the screening, 109 CT scans with eligibility criteria were included in this study. RESULTS There were 109 cases in this study; 50 (45.9%) of them were male and 59 (54.1%) were female. Moskowitz artery was found in 18 (16.5%) cases; 8 were males and 10 were females. Riolan's arch was present in 30 cases, of whom 15 were male and 15 were female. In our study Moskowitz artery and Riolan's arch were monitored as separate vascular structures, and in all cases with Moskowitz artery, Riolan's arch was also present. There was a statistically significant difference (p < 0.05) between the combined MCA emerging type and the presence of MA, and 12 cases with combined branch and 6 cases with single branch had Moskowitz artery. There was a statistically significant difference (p < 0.05) between LCA types and the presence of MA, and the Moskowitz artery was the most common seen at type 1 LCA. CONCLUSIONS Knowledge of the relationship between Riolan's arch and the Moskowitz artery is valuable, and preoperative evaluation of this artery may be beneficial in the presence of Riolan's arch. In addition, preoperative radiological evaluation and its importance are prominent in minimising intraoperative bleeding during splenic flexure mobilisation with a medial laparoscopic approach and reducing the risk of colorectal anastomosis leakage.

Abstract
BACKGROUND The purpose of this systematic review and meta-analysis was to determine the prevalence of the number of sigmoid arteries (SA) and variations in their origins. METHODS A thorough systematic search of literature through February 2020 was conducted on major electronic databases to identify eligible studies. Data were extracted and pooled into a meta-analysis using Metafor package in R. The primary outcome was the variations in the SA origin (according to modified Zebrowski classification), and the secondary outcome was the prevalence of the number of SA. RESULTS A total of 22 studies (n = 2653 patients) were included. Type 1 modified Zebrowski (separated origins or common trunk of the SA originating from descending recto-sigmoid trunk (DRST)) was the most common origin type of the SA (pooled prevalence estimate (PPE) = 49.67% (95% CI 32. 67- 66.71)), while type 3 (separated origins or common trunk of 1 or 2 SA originating from DRST or superior rectal artery (SRA) and 1 or 2 SA originating from DRST or SRA) was the least common (PPE = 0.18%; 95% CI 0.00-2.82)). Of the Type 1 variants, the not specified (N.S) variant was by far the most prevalent. The number of SA ranged from one to five, with three being the mode (PPE = 42.3%). CONCLUSION This is the most comprehensive analysis of arterial vascular anatomy of the sigmoid colon. In light of the highly variable anatomical pattern displayed by the SA, thorough pre-operative knowledge of their anatomy can be crucial in minimizing incidences of iatrogenic injury.

Abstract
The aim of this study is to determine vertebral levels of the coeliac trunk, the superior mesenteric artery, and the inferior mesenteric artery originated from the abdominal aorta and to calculate the distance measurements between these arteries and between these arteries and the aortic bifurcation by multidetector computed tomography angiography technique. It was determined that the nine different vertebral levels of the coeliac trunk, the nine different vertebral levels of the superior mesenteric artery, and the eleven different vertebral levels of the inferior mesenteric artery. The distance measurements between the coeliac trunk and the superior mesenteric artery, the inferior mesenteric artery, the aortic bifurcation were found significant between female and male. In this study, it was determined more different levels than the levels described in classical anatomy. The preoperative information of these morphological variations can contribute to the reduction of surgical time and perioperative vascular complications especially for anterior lumbar interbody fusion and defining the location of the primary lymphatic drainage site for gastrointestinal malignancies.

Systematic review and meta-analysis of the anatomical variants of the left colic artery. Colorectal Dis 2020; 22:768-778. [PMID: 31655010 DOI: 10.1111/codi.14891] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2019] [Accepted: 09/30/2019] [Indexed: 12/12/2022]
Abstract
AIM To provide a comprehensive evidence-based assessment of the anatomical variations of the left colic artery (LCA). METHOD A thorough systematic search of the literature up until 1 April 2019 was conducted on the electronic databases PubMed, SCOPUS and Web of Science (WOS) to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using the Metafor package in R. The primary outcomes of interest were the absence of the LCA and the anatomical variants of its origin. The secondary outcomes were the distance (mean ± SD) between the origin of the inferior mesenteric artery (OIMA) and the origin of the left colic artery (OLCA). RESULTS A total of 19 studies (n = 2040 patients) were included. The pooled prevalence estimate (PPE) of LCA absence was 1.2% (95% CI 0.0-3.6%). Across participants with either a Type I or Type II LCA, the PPE of a Type I LCA was 49.0% (95% CI 40.2-57.8%). The PPE of a Type II LCA was therefore 51.0%. The pooled mean distance from the OIMA to the OLCA was 40.41 mm (95 CI% 38.69-42.12 mm). The pooled mean length of a Type I LCA was 39.12 mm (95% CI 36.70-41.53 mm) while the pooled mean length of a Type IIa and Type IIb LCA was 41.43 mm (95% CI 36.90-43.27 mm) and 39.64 mm (95% CI 37.68-41.59 mm), respectively. CONCLUSION Although the absence of the LCA is a rare occurrence (PPE 1.2%), it may be associated with an important risk of anastomotic leakage as a result of insufficient vascularization of the proximal colonic conduit. It is also necessary to distinguish variants I and II of Latarjet, the frequency of which is identical, with division of the LCA being technically more straightforward in variant I of Latarjet. Surgeons should be aware that technical difficulties are likely to be more common with variant II of Latarjet, as LCA ligation may be more difficult due to its close proximity to the inferior mesenteric vein (IMV).

Zhang C, Li A, Luo T, Li Y, Li F, Li J. Evaluation of characteristics of left-sided colorectal perfusion in elderly patients by angiography. World J Gastroenterol 2020; 26:3484-3494. [PMID: 32655271 PMCID: PMC7327791 DOI: 10.3748/wjg.v26.i24.3484] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2020] [Revised: 04/30/2020] [Accepted: 05/18/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Handling of the inferior mesenteric artery (IMA) and maintaining anastomotic perfusion are important in radical resection of left-sided colorectal cancer. However, the branching of this artery and the drainage patterns of this vein vary among individuals, and the characteristics and perfusion region of this artery in elderly patients remain unclear.
AIM To evaluate the characteristics and perfusion region of the IMA in elderly patients using angiography.
METHODS We enrolled 154 patients (> 65 years old) who underwent digital subtraction angiography of the IMA. The characteristics, bifurcation, and distribution of the IMA and termination of the anastomotic perfusion of the left colon and rectum were examined using digital subtraction angiography. Collateral arterial arches and the IMA hemoperfusion region were also recorded. Perfusion regions were cross-referenced with clinical and anatomical features by the univariate analysis.
RESULTS Of 154 patients, 25 (16.2%) had IMA lesions. The left colic artery arose independently from the IMA in 44.2% of patients, shared a trunk with the sigmoid artery in 35.1%, shared an opening with the sigmoid and superior rectal arteries in 16.9%, and was absent in 5.1%. The IMA perfusion region stopped at the splenic flexure in 50 (32.5%) patients. The collateral circulation existed in the colonic perfusion region, including the marginal artery (Drummond’s artery), the ascending branch of the left colonic artery to supply the transverse colon, and the arc of Riolan with a frequency of 100%, 22.7%, and 1.9%, respectively. The IMA perfusion region was independently associated with the comorbidity of atherosclerosis, IMA atherosclerotic lesion, branching pattern, collateral circulation, and marginal artery integrity.
CONCLUSION The IMA and its branches are prone to arteriosclerosis, and IMA perfusion may be interrupted at the splenic flexure in elderly patients. The applicability and precision of preoperative angiography for evaluating the IMA branching and perfusion patterns could facilitate geriatric laparoscopic left-sided colorectal cancer surgery with suspicion of poor IMA perfusion.

A three-dimensional computed tomography angiography study of the anatomy of the accessory middle colic artery and implications for colorectal cancer surgery. Surg Radiol Anat 2020; 42:1509-1515. [PMID: 32500228 PMCID: PMC7644475 DOI: 10.1007/s00276-020-02511-w] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Accepted: 05/29/2020] [Indexed: 12/17/2022]
Abstract
Purpose In the present study, we focused on the accessory middle colic artery and aimed to increase the safety and curative value of colorectal cancer surgery by investigating the artery course and branching patterns. Methods We included 143 cases (mean age, 70.4 ± 11.2 years; 86 males) that had undergone surgery for neoplastic large intestinal lesions at the First Department of Surgery at Yamagata University Hospital between August 2015 and July 2018. We constructed three-dimensional (3D) computed tomography (CT) angiograms and fused them with reconstructions of the large intestines. We investigated the prevalence of the accessory middle colic artery, the variability of its origin, and the prevalence and anatomy of the arteries accompanying the inferior mesenteric vein at the same level as the origin of the inferior mesenteric artery. Results Accessory middle colic artery was observed in 48.9% (70/143) cases. This arose from the superior mesenteric artery in 47, from the inferior mesenteric artery in 21, and from the celiac artery in two cases. In 78.2% (112/143) cases, an artery accompanying the inferior mesenteric vein was present at the same level as the origin of the inferior mesenteric artery; this artery was the left colic artery in 92, the accessory middle colic artery in 11, and it divided and became the left colic artery and the accessory middle colic artery in 10 cases. Conclusion 3D CT angiograms are useful for preoperative evaluation. Accessory middle colic arteries exist and were observed in 14.9% of cases.

Abstract
BACKGROUND It is important for lymph node dissection around the inferior mesenteric artery (IMA) with preservation of the left colic artery (LCA) to be aware of the track and the length of the LCA. We aimed to investigate the branching pattern and trajectory of LCA and measure the distances from the root of the IMA to the origin of the LCA (D mm) and from the origin of LCA to intersection of LCA and IMV (d mm) during laparoscopic left-sided colorectal operations. METHODS We analyzed 106 patients who underwent laparoscope-assisted left-side colorectal surgery during laparoscopic surgery. The branching patterns among the IMA, LCA, and sigmoidal trunk were evaluated; the trajectory of LCA was examined; the D mm and d mm were measured using a length of silk in the surgical operation. RESULTS In 59.5% patients, the LCA arose independently from the sigmoidal trunk (type A); in 8.5% patients, the LCA and sigmoidal trunk arose from the IMA at the same point (type B); in 29.2% patients, the LCA and sigmoidal trunk had a common trunk (type C); the LCA did not exist in 2.8% (type D).The D mm and d mm for all cases ranged from 15.0 to 65.3 mm (median, 43.1 mm) and from 20.3 to 46.2 mm (median, 34.8 mm), respectively. 74.8% of the LCA went straight upper left and upward to proximal part of descending colon (type I), 25.2% went to the lower left at first, then turned to travel straight upward to proximal part of descending colon (type II). CONCLUSION This study showed the anatomic variations of LCA during laparoscopic left-sided colorectal operation, which would help surgeons safely perform laparoscopic surgery in the left-side colon and rectum.

Abstract
Purpose Colon perfusion status is one of the most important factors for the determination of postoperative anastomotic complications. Colonic hypoperfusion can be induced by inferior mesenteric artery (IMA) ligation in some patients. This study aimed to evaluate atherosclerotic risk assessment and vascular parameters of CT angiography as predictors of colonic hypoperfusion. Methods This prospective study was conducted at a tertiary referral hospital and included 46 rectosigmoid colon cancer patients undergoing laparoscopic anterior resection between August 2013 to July 2014. Atherosclerotic risk scores were assessed using the Framingham cardiovascular risk score system. The IMA length, branching pattern, atherosclerotic calcification, and intermesenteric artery and mesenteric vascular diameters were evaluated using CT angiography. Mesenteric marginal artery pressures were measured before and after IMA clamping. The mean arterial pressure (MAP) index was calculated by dividing the mesenteric marginal MAP into the systemic MAP to determine the mesenteric hypoperfusion status after IMA clamping. A critically low MAP index was defined as <0.4. Results Critically low MAP index (<0.4) was observed in 6 cases (13.0%) after IMA clamping. Atherosclerotic calcification of the IMA and superior mesenteric artery occurred in 11 (23.9%) and 5 patients (10.9%), respectively. Low MAP index was associated with high atherosclerotic risk score and short IMA length, rather than atherosclerotic calcification and other vascular parameters of the major mesenteric arteries. Multivariate analysis indicated that high atherosclerotic risk and short IMA length were independent predictors of critically low MAP index. Conclusion Atherosclerotic risk assessment and IMA length were useful predictors of the mesenteric hypoperfusion status following IMA ligation during laparoscopic rectosigmoid colon surgery.

Results of a systematic review and meta-analysis. Colorectal Dis 2019; 21:623-631.

Abstract
AIM In colorectal cancer, ligation of the inferior mesenteric artery (IMA) is a standard surgical approach. In contrast, ligation of the IMA is not mandatory during treatment of diverticular disease. The object of this meta-analysis was to assess if preservation of the IMA reduces the risk of anastomotic leakage. METHOD A search was performed up to August 2018 using the following electronic databases: MEDLINE/PubMed, ISI Web of Knowledge and Scopus. The measures of treatment effect utilized risk ratios for dichotomous variables with calculation of the 95% CI. Data analysis was performed using the meta-analysis software Review Manager 5.3. RESULTS Eight studies met the inclusion criteria and were included in the meta-analysis: two randomized controlled trials (RCTs) and six non-RCTs with 2190 patients (IMA preservation 1353, ligation 837). The rate of anastomotic leakage was higher in the IMA ligation group (6%) than the IMA preservation group (2.4%), but this difference was not statistically significant [risk ratio (RR) 0.59, 95% CI 0.26-1.33, I2 = 55%]. The conversion to laparotomy was significantly lower in the IMA ligation group (5.1%) than in the IMA preservation group (9%) (RR 1.74, 95% CI 1.14-2.65, I2 = 0%). Regarding the other outcomes (anastomotic bleeding, bowel injury and splenic damage), no significant differences between the two techniques were observed. CONCLUSION This meta-analysis failed to demonstrate a statistically significant difference in the anastomotic leakage rate when comparing IMA preservation with IMA ligation. Thus, to date there is insufficient evidence to recommend the IMA-preserving technique as mandatory in resection for left-sided colonic diverticular disease.

Abstract
BACKGROUND To perform a safe and precise laparoscopic surgery for the splenic flexure cancer, it is important for surgeons to gain a preoperative understanding of the running of the feeding artery of the splenic flexure. We evaluated the blood supply to the splenic flexure by using preoperative three-dimensional computed tomography (3D-CT). METHOD We retrospectively analyzed a total of 88 patients with colorectal cancer who underwent preoperative 3D-CT at our institutions between April 2016 and June 2017. RESULTS The arterial blood supply to the splenic flexure was divided into four patterns as follows: type 1, the left branch of the middle colic artery (MCA) with common trunk and the left colic artery (LCA) (n = 48, 54.5%); type 2, the left branch of the MCA with independent origin and the LCA (n = 8, 9.1%); type3, the accessory-MCA (A-MCA) and the LCA (n = 27, 30.7%); and type4, the LCA alone (n = 5, 5.7%). The MCA had the common trunk of the right and left branches in the majority of cases (85.2%). The right and left branches of the MCA arose separately from the superior mesenteric artery (SMA) in 8 of 88 patients (9.1%). CONCLUSIONS The arterial patterns of the splenic flexure were classified into four patterns by using preoperative 3D-CT. The A-MCA existed in 30% of the patients in this study. These information should be helpful to perform the optimal surgery for the splenic flexure cancer.

Abstract
The splenic flexure is an uncommon location of colorectal cancer, being involved in 2%–3% of cases. The low chance of being engaged in resecting cancer of the splenic flexure can make it difficult for surgeons to build their learning curve and to achieve a reliable experience. As the majority of colectomies are still performed by low-volume surgeons, there is growing agreement that providing local services with adequate surgical education and training could be an effective strategy to improve outcomes and global health. Arming surgeons with simplified and easy-to-learn surgical techniques could be an important step of this strategy. A novel simplified technique for laparoscopic resection of the splenic flexure is presented, which combines laparoscopic mobilisation of the right colon with extracorporeal vascular ligation and bowel anastomosis.
