Retrospective analysis of immediate and long-term results of NOSES technique and conventional laparoscopic-assisted resection in patients with colorectal cancer. Front Surg 2024; 11:1444942. [PMID: 39364371 PMCID: PMC11446899 DOI: 10.3389/fsurg.2024.1444942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2024] [Accepted: 09/09/2024] [Indexed: 10/05/2024] Open
Abstract
Introduction The aim of research was to study the feasibility and safety of surgery providing specimen extraction through natural orifices in patients with colorectal cancer. Materials and methods This study is a comparative retrospective analysis of findings obtained from 265 patients who underwent surgical treatment using NOSES technique and 275 patients who underwent laparoscopic-assisted (LA) resection. Data included preoperative patients' information, intraoperative findings, results of postoperative pathological examination of surgical specimens, early postoperative period analysis, and follow-up. Results Both groups were comparable in terms of gender, age and BMI. The duration of surgery was similar in both groups (p = 0.94). Intraoperative blood loss under NOSES interventions was slightly lower than in laparoscopic-assisted surgeries (p < 0.001). There was no significant difference in the number of lymph nodes removed and anal function scores between the two groups (p > 0.05). It was revealed that in the NOSES group, the function of the gastrointestinal tract normalized at an earlier time, slightly the time to start liquid food intake and the duration of postoperative hospital stay were reduced (p < 0.001). A statistically significant difference between groups was found in complications, such as pneumonia (p = 0.03). The absolute number of complications was observed more often in the LA surgery group (10.4%) than in the NOSES group (5.8%). Local recurrence was less common in the NOSES group (p = 0.01). There were no statistically significant differences in disease progression (p = 0.16). When analyzing disease-free and overall survival rate in this study, there was no statistically significant difference between the two surgical techniques in terms of their effect on postoperative survival (p > 0.05). Conclusion The results of this study demonstrate that NOSES technique is a relatively safe and effective surgical option in patients with colorectal cancer. It has high surgical efficiency providing no increased risk of surgical intervention, reducing total number of postoperative complications, reducing duration of postoperative hospital stay, reducing the time for gastrointestinal function recovery and the start of food intake. This study supports that NOSES has clear advantages over conventional laparoscopic-assisted surgery.

Abstract
PURPOSE To study the safety and efficacy of laparoscopic subtotal colectomy (LASC) with cecorectal anastomosis for slow-transit constipation (STC). METHODS This study was a retrospective review of all patients undergoing LASC with cecorectal anastomosis for STC between March 2010 and May 2017. The main variables included the operative time, blood loss, length of postoperative hospital stay, complications, and long-term outcomes. RESULTS In this analysis, 56 patients were included. There were 17 males and 39 females aged between 34 and 80 years old. The mean operative time was 208 ± 21 min, and the mean perioperative blood loss was 116 ± 48 mL. The mean postoperative hospital stay was 7.7 ± 3.5 days, and the incidence of perioperative complications was 19.6%, with no mortality. One patient required reoperation because of intra-abdominal bleeding. During the follow-up period, 26.8% of patients suffered from chronic pain and bloating, with no recurrence of STC. The causes of these symptoms included small bowel obstruction (7.1%), slow transit (10.7%), anastomotic stenosis (5.4%) and gastroptosis (3.6%). Postoperatively, after 12 months, the frequency of defecation was 2-4 times per day. Patients with follow-up of at least 60 months, the mean frequency of defecation was 0.9 ± 0.5 times per day. The percentage of satisfaction was 82.1%. CONCLUSION LASC with cecorectal anastomosis is a safe and effective surgical approach for STC, with the majority of patients being satisfied with the outcome of surgery.

Two cases of laparoscopic total colectomy with natural orifice specimen extraction and review of the literature. Wideochir Inne Tech Maloinwazyjne 2017; 12:291-296. [PMID: 29062451 PMCID: PMC5649505 DOI: 10.5114/wiitm.2017.69227] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2016] [Accepted: 05/07/2017] [Indexed: 01/29/2023] Open
Abstract
We present two cases of natural orifice specimen extraction (NOSE) after laparoscopic total colectomy and ileorectal anastomosis (TC-IRA), and we also review all of the previously reported cases. Our aim was to focus on patient selection for NOSE after TC-IRA. The PubMed and Google Scholar databases were scanned. Demographic features, surgical indications, and techniques were analyzed. Basic calculations were used for statistical analysis. A total of 13 cases were detected in addition to our 2 cases. All of the specimens were removed through the natural orifices successfully. No case required a diverting ileostomy. No patients were converted to open surgery or to conventional laparoscopy. Complications were reported in three patients. Transanal extractions were performed in 12 cases (10 colonic inertia, 2 polyposis), and transvaginal extractions were performed in 3 cases (2 malignancy, 1 colonic inertia). Both transanal and transvaginal specimen extractions after laparoscopic TC-IRA can be preferred. However, transanal extraction seems to be feasible in cases of TC for benign disease with a limited mesenteric-omental resection. If the indication is a malignancy requiring a mesenteric-omental resection, a transvaginal route should be preferred for a voluminous specimen.

Abstract
BACKGROUND Recent developments in classical minimally invasive surgical procedures for colon resection aimed to minimize or even eliminate abdominal wall incisions, thus improving postoperative pain, patient recovery and aesthetics. A promising approach is the total laparoendoscopic colectomy (LEC) with transanal sample extraction. The aim of this study was the comparison of total LEC with conventional laparoscopic assisted surgery (LAS) and extraction incision. METHOD We included 168 consecutive patients (LEC:112; LAS:56) with diverticular disease, rectal prolapse, benign or malignant tumors and analyzed retrospectively. The specimen was extracted transanally by LEC with a specially developed rectoscope; the LAS group required a minilaparotomy of 5 cm. The primary outcome was postoperative pain. Secondary outcomes included operating time, minor and major complication rates, number and length of extracted specimens, additional pain medication and duration of hospital stay. RESULTS The measured postoperative pain score values did not significantly differ between the two groups; however, consumption of postoperative pain medication was significantly higher in the LAS-group (p < 0.001). Due to the learning curve, the median operating time in the LEC group (120 min) was slightly longer than in the LAS group (100 min); however, it was reduced to 95 min in the last 50 operations. Patients in the LEC group were discharged from hospital one day earlier (median duration of hospital stay 6 days, p = 0.003). Compliaction rates were similar in both groups. CONCLUSION The technique of total LEC with transanal specimen extraction is designed to avoid a minilaparotomy and its associated morbidities. The LEC operation is feasible for a large group of patients, including overweight patients. The superiority of LEC in terms of reduced pain medication, shorter hospital stay and faster patient recovery, as shown in this study, needs to be confirmed by randomized controlled trials with longer follow-up periods.

Abstract
The aim of this study was to demonstrate the feasibility of laparoscopic restorative proctocolectomy (LRPC) without additional abdominal incisions. Two sisters with familial adenomatous polyposis were enrolled. The colon and rectum were mobilized entirely through the five abdominal trocars. The terminal ileum and distal rectum were transected with endoscopic staplers. The entire colorectal specimen was extracted transanally. A circular stapler anvil was introduced transanally. The J-pouch was created intracorporeally. The rectal stump was re-closed and a pouch-anal anastomosis was created using a circular stapler. We used a transanal tube for decompression of the pouch instead of a diverting ileostomy. The patients were discharged on the 10th and 12th days uneventfully. Both were doing well with their pouches after 18.5 and 12.1 months of follow-up. With the help of transanal specimen extraction and transanal tube decompression, additional abdominal incisions can be avoided following LRPC.

Abstract
AIM: To study the transcolonic extraction of the proximally resected colonic specimens by colonoscopic assistance at laparoscopic colonic surgery.
METHODS: The diagnoses of our patients were Crohn’s disease, carcinoid of appendix and adenocarcinoma of cecum. We preferred laparoscopic total mesocolic resections. Colon and terminal ileum were divided with endoscopic staplers. A colonoscope was placed per anal and moved proximally in the colon till to reach the colonic closed end under the laparoscopic guidance. The stump of the colon was opened with laparoscopic scissors. A snare of colonoscope was released and the intraperitoneal complete free colonic specimen was grasped. Specimen was moved in to the colon with the help of the laparoscopic graspers and pulled gently through the large bowel and extracted through the anus. The open end of the colon was closed again and the ileal limb and the colon were anastomosed intracorporeally with a 60-mm laparoscopic stapler. The common enterotomy orifice was closed in two layers with a running intracorporeal suture.
RESULTS: There were three patients with laparoscopic right-sided colonic resections and their specimens were intended to remove through the remnant colon by colonoscopy but the procedure failed in one patient (adenocarcinoma) due to a bulky mass and the specimen extraction was converted to transvaginal route. All the patients had prior abdominal surgeries and had related adhesions. The operating times were 210, 300 and 500 min. The lengths of the specimens were 13, 17 and 27 cm. In our cases, there were no superficial or deep surgical site infections or any other complications. The patients were discharged uneventfully within 4-5 d and they were asymptomatic after a mean 7.6 mo follow-up (ranged 4-12). As far as we know, there were only 12 cases reported yet on transcolonic extraction of the proximal colonic specimens by colonoscopic assistance after laparoscopic resections. With our cases, success rate of the overall experience in the literature was 80% (12/15) in selected cases.
CONCLUSION: Transcolonic specimen extraction for right-sided colonic resection is feasible in selected patients. Both natural orifice surgery and intracorporeal anastomosis avoids mini-laparotomy for specimen extraction or anastomosis.

Abstract
Over the last 20 years, laparoscopic colorectal surgery has shown equal efficacy for benign and malignant colorectal diseases when compared to open surgery. However, a laparoscopic approach reduces postoperative morbidity and shortens hospital stay. In the quest to optimize outcomes after laparoscopic colorectal surgery, reduction of access trauma could be a way to improve recovery. To date, one method to reduce access trauma is natural orifice specimen extraction (NOSE). NOSE aims to reduce access trauma in laparoscopic colorectal surgery. The specimen is delivered via a natural orifice and the anastomosis is created intracorporeally. Different methods are used to extract the specimen and to create a bowel anastomosis. Currently, specimens are delivered transcolonically, transrectally, transanally, or transvaginally. Each of these NOSE-procedures raises specific issues with regard to operative technique and application. The presumed benefits of NOSE-procedures are less pain, lower analgesia requirements, faster recovery, shorter hospital stay, better cosmetic results, and lower incisional hernia rates. Avoidance of extraction site laparotomy is the most important characteristic of NOSE. Concerns associated with the NOSE-technique include bacterial contamination of the peritoneal cavity, inflammatory response, and postoperative outcomes, including postoperative pain and the functional and oncologic outcomes. These issues need to be studied in prospective randomized controlled trials. The aim of this systematic review is to describe the role of NOSE in minimally invasive colorectal surgery.

Abstract
OBJECTIVE To review the published studies reporting various specimen retrieval incisions being used by colorectal surgeons in patients undergoing laparoscopic colorectal resections (LCR). METHODS Standard medical electronic databases were searched to find relevant articles and a summary conclusion was generated. RESULTS There were 43 studies reporting various approaches used for the purpose of specimen retrieval in 2388 patients undergoing LCR. The most common approaches were periumbilical midline incision (1260 reported case in the literature), transverse incision (583 reported cases in the literature) in the right- or left iliac fossa, depending on the side of colonic resection, and Pfannensteil incision (293 reported cases in the literature). Periumbilical midline incision was associated with the higher risk of developing incisional hernia (odds ratio 53.72; 95% confidence interval 7.48-386.04; Z = 3.96; P = 0.0001). In terms of surgical site infection (SSI), there was no difference between the three common approaches to specimen retrieval. Transanal and transvaginal approaches were associated with higher risk of SSI. CONCLUSIONS Midline, transverse and Pfannensteil incisions were the most commonly used approaches for specimen retrieval following LCR. Midline incision was associated with higher risk of incisional hernia. Risk of SSI was similar in all three common approaches. The transanal and transvaginal approaches pose a higher risk of SSI. These conclusions are based on the combined outcome of published case series, case reports and comparative studies. Randomized, controlled trials with longer follow-up are required before recommending the routine use of any approach for specimen retrieval in patients undergoing LCR.

Abstract
BACKGROUND The German NOTES registry (GNR) is the largest published database for natural orifice transluminal endoscopic surgery (NOTES) worldwide. Although transvaginal cholecystectomy is the most frequent procedure in the GNR, the number of colorectal resections is increasing. The objective of this study was to analyze the first 139 colonic procedures of the GNR. METHODS All colonic procedures from the GNR were analyzed regarding patient- and therapy-related parameters. A multivariate analysis was conducted for transvaginal sigmoid resections regarding procedural time, hospital stay, conversion rate, and rate of complications. RESULTS From October 2008 to January 2013, 139 colon NOTES procedures (12 male, 127 female) were registered. Main diagnoses were sigmoid diverticulitis (85.6 %), colon carcinoma (9.4 %), and ulcerative colitis (3.6 %). Sigmoid resections (87.1 %), proctocolectomies (3.6 %), right-sided resections (2.9 %), left-sided resections (3.6 %), segmental resections (2.2 %), and 1 ileocecal resection (0.7 %) were performed. All procedures were conducted in transvaginal (87.8 %) or transrectal (12.2 %) hybrid technique, with a median of 3 percutaneous trocars. Conversions to laparoscopic technique were necessary in 3.6 % (none to conventional technique). Intraoperative complications were recorded in 2.9 % and postoperative complications in 12.2 %. The institutional case number in transvaginal sigmoid resections correlated negatively with procedural time (p = 0.041) and the number of percutaneous trocars (p = 0.002). CONCLUSION The analysis of the first 139 colon NOTES operations of the GNR shows the feasibility of co on operations in hybrid technique, especially for transvaginal sigmoid resection as the most frequent procedure.

Abstract
Laparoscopic surgery for colorectal disease is an evolving, dynamic subject undergoing constant adaptation. Hence there are significant ongoing advances in technique and technology as has been seen with the emergence of single port and Natural Orifice Transluminal Endoscopic operations with already considerable ramifications for many aspects of minimal access surgery. Most recently single port technologies and expertise have synergized with Transanal Endoscopic (TEM/TEO) experience to allow their convergence out of their respective niches so that pelvic surgery can be laparoendoscopically performed from both its abdominal and perineal aspects. Distinct from wound-related benefits, such capacity for high resolution and multi-dimensional imaging relates significant benefit to the operating team and patient. This state of the art review demonstrates the crucial perspective that advanced practices and performance capabilities are intrinsically complimentary rather than competitive. All surgeons need therefore to participate in adapting their practice styles to allow technical step-advance across the discipline.

Abstract
PURPOSE To assess the functional outcomes and quality of life in patients with laparoscopic total colectomy for slow-transit constipation (STC). METHODS All patients undergoing laparoscopic colectomy with ileorectal anastomosis for colonic inertia at two referral centers were analyzed. Their preoperative, intraoperative and postoperative details were recorded with a one-year follow-up. Their quality of life was assessed using the SF-36 questionnaire. RESULTS Between 2004 and 2007, 710 patients were evaluated. Eight female patients (1.1 %) fulfilled the criteria for STC without obstructive defecation syndrome. Their mean age was 38 years ± 15 (range from 22 to 62). The conversion rate was 12.5 %. The morbidity rate was 37.5 %, and mortality was nil. The preoperative abdominal pain was 6.6 ± 0.3 and had decreased to 3.6 ± 2.3 postoperatively (P = 0.008). At 1 year, the defecation frequency per week had increased from 0.84 ± 0.24 to 6.75 ± 3.4 (P = 0.001). Three patients developed nocturnal leakage (37.5 %). Eighty-eight percent of the patients recommend the procedure. All parameters of the SF-36 questionnaire had improved at the one-year follow-up examination. CONCLUSION Laparoscopic colectomy for slow-transit constipation is safe and increased the number of evacuations per week. Although nocturnal leakage may occur, these patients experience improvements in their quality of life.

Abstract
AIM: To introduce transvaginal or transanal specimen extraction in laparoscopic total mesorectal excision surgery to avoid an abdominal incision.
METHODS: Between January 2009 and December 2011, 21 patients with rectal cancer underwent laparoscopic radical resection and the specimen was retrieved by two different ways: transvaginal or transanal rectal removal. Transvaginal specimen extraction approach was strictly limited to elderly post-menopausal women who need hysterectomy. Patients aged between 30 and 80 years, with a body mass index of less than 30 kg/m2, underwent elective surgery. The surgical technique and the outcomes related to the specimen extraction, such as duration of surgery, length of hospital stay, and the complications were retrospectively reviewed.
RESULTS: Laparoscopic resection using a natural orifice removal approach was successful in all of the 21 patients. Median operating time was 185 min (range, 122-260 min) and the estimated blood loss was 48 mL. The mean length of hospital stay was 7.5 d (range, 2-11 d). One patient developed postoperative ileus and had an extended hospital stay. The patient complained of minimal pain. There were no postoperative complications or surgery-associated death. The mean size of the lesion was 2.8 cm (range, 1.8-6.0 cm), and the mean number of lymph nodes harvested was 18.7 (range, 8-27). At a mean follow-up of 20.6 mo (range, 10-37 mo), there were no functional disorders associated with the transvaginal and transanal specimen extraction.
CONCLUSION: Transvaginal or transanal extraction in L-TME is a safe and effective procedure. Natural orifice specimen extraction can avoid the abdominal wall incision and its potential complications.
