Abstract
PURPOSE Solitary fibrous tumors (SFT) are a rare entity of in majority benign neoplasms. Nevertheless, up to 20% of cases show a malignant tendency with local infiltration or metastasis. Commonly arising in the thoracic cavity, only few cases of SFT of the mesorectal tissue have been reported in the literature. Complete surgical resection, classically by posterior approach, is the treatment of choice. The purpose of this review is to demonstrate the safety and suitability of transanal minimally invasive surgery (TAMIS) as a surgical approach for the resection of benign pararectal solid tumors. METHODS We report the case of a 52-year-old man who was diagnosed incidentally with SFT of the distal mesorectum. Resection by TAMIS was performed. Based on this case, we describe the steps and potential benefits of this procedure and provide a comprehensive review of the literature. RESULTS Histopathology confirms the completely resected SFT. After uneventful postoperative course and discharge on day four, follow-up was recommended by a multidisciplinary board by clinical examination and MRI, which showed a well-healed scar and no recurrence up to 3 years after resection. CONCLUSION SFT of the mesorectum is a very rare entity. To our knowledge, this is the first report on a TAMIS resection for SFT, demonstrated as a safe approach for complete resection of benign pararectal solid tumors.

Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) is an advanced technique for excision of early rectal cancers. Robotic TAMIS (r-TAMIS) has been introduced as technical improvement and potential alternative to total mesorectal excision (TME) in early rectal cancers and in frail patients. This study reports the perioperative and short-term oncological outcomes of r-TAMIS for local excision of early-stage rectal cancers. METHODS Retrospective analysis of a prospectively collected r-TAMIS database (July 2021-July 2023). Demographics, clinicopathological features, short-term outcomes, recurrences, and survival were investigated. RESULTS Twenty patients were included. Median age and body mass index were 69.5 (62.0-77.7) years and 31.0 (21.0-36.5) kg/m2. Male sex was prevalent (n = 12, 60.0%). ASA III accounted for 66.7%. Median distance from anal verge was 7.5 (5.0-11.7) cm. Median operation time was 90.0 (60.0-112.5) minutes. Blood loss was minimal. There were no conversions. Median postoperative stay was 2.0 (1.0-3.0) days. Minor and major complication rates were 25.0% and 0%, respectively. Seventeen (85.0%) patients had an adenocarcinoma whilst three patients had an adenoma. R0 rate was 90.0%. Most tumours were pT1 (55.0%), followed by pT2 (25.0%). One patient (5.0%) had a pT3 tumour. Specimen and tumour maximal median diameter were 51.0 (41.0-62.0) mm and 21.5 (17.2-42.0) mm, respectively. Median specimen area was 193.1 (134.3-323.3) cm2. Median follow-up was 15.5 (10.0-24.0) months. One patient developed local recurrence (5.0%). CONCLUSIONS r-TAMIS, with strict postoperative surveillance, is a safe and feasible approach for local excision of early rectal cancer and may have a role in surgically unfit and elderly patients who refuse or cannot undergo TME surgery. Future prospective multicentre large-scale studies are needed to report the long-term oncological outcomes.

Abstract
INTRODUCTION Robotic transanal minimally invasive surgery (R-TAMIS) was introduced in 2012 for the excision of benign rectal polyps and low grade rectal cancer. Ergonomic improvements over traditional laparoscopic TAMIS (L-TAMIS) include increased dexterity within a small operative field, with possibility of better surgical precision. We aim to collate the existing data surrounding the use of R-TAMIS to treat rectal neoplasms from cohort studies and larger case series, providing a foundation for future, large-scale, comparative studies. METHODS Medline, EMBASE and Web of Science were searched as part of our review. Randomised controlled trials (RCTs), cohort studies or large case series (≥ 5 patients) investigating the use of R-TAMIS to resect rectal neoplasia (benign or malignant) were eligible for inclusion in our analysis. Quality assessment of included studies was performed via the Newcastle Ottawa Scale (NOS) risk of bias tool. Outcomes extracted included basic participant characteristics, operative details and histopathological/oncological outcomes. RESULTS Eighteen studies on 317 participants were included in our analysis. The quality of studies was generally satisfactory. Overall complication rate from R-TAMIS was 9.7%. Clear margins (R0) were reported in 96.2% of patients. Local recurrence (benign or malignant) occurred in 2.2% of patients during the specified follow-up periods. CONCLUSION Our review highlights the current evidence for R-TAMIS in the local excision of rectal lesions. While R-TAMIS appears to have complication, margin negativity and recurrence rates superior to those of published L-TAMIS series, comparative studies are needed.

Abstract
BACKGROUND In the advancement of transanal local excision, robot-assisted transanal minimal invasive surgery is the newest development. In the confined area of the rectum, robot-assisted surgery should, theoretically, be superior due to articulated utensils, video enhancement, and tremor reduction, however, this has not yet been investigated. The aim of this study was to review the evidence reported to-date on experience of using robot-assisted transanal minimal invasive surgery for treatment of rectal neoplasms. METHODS A comprehensive literature search of Embase and PubMed from May to August 2021were performed. Studies including patients diagnosed with rectal neoplasia or benign polyps who underwent robot-assisted transanal minimal invasive surgery were included. All studies were assessed for risk of bias through assessment tools. Main outcome measures were feasibility, excision quality, and complications. RESULTS Twenty-five studies with a total of 322 local excisions were included. The studies included were all retrospective, primarily case-reports, -series, and cohort studies. The median distance from the anal verge ranged from 3.5 to 10 cm and the median size was between 2.5 and 5.3 cm. Overall, 4.6% of the resections had a positive resection margin. The overall complication rate was at 9.5% with severe complications (Clavien-Dindo score III) at 0.9%. CONCLUSION Based on limited, retrospective data, with a high risk of bias, robot-assisted transanal minimal invasive surgery seems feasible and safe for local excisions in the rectum.

Abstract
Transanal endoscopic surgery (TES), which is performed through a variety of transanal endoluminal multitasking surgical platforms, was developed to facilitate endoscopic en bloc excision of rectal lesions as a minimally invasive alternative to radical proctectomy. Although the oncologic safety of TES in the treatment of malignant rectal tumors has been an area of vigorous controversy over the past two decades, TES is currently accepted as an oncologically safe approach for the treatment of carefully selected early and superficial rectal cancers. TES can also serve as both a diagnostic and potentially curative treatment of partially resected unsuspected malignant polyps. In this article, indications and contraindications for transanal endoscopic excision of early rectal cancer lesions are reviewed, as well as selection criteria for the most appropriate transanal excisional approach. Preoperative preparation and surgical technique for complications of TES will be reviewed, as well as recommended surveillance and management of upstaged tumors.

Abstract
Robotic transanal minimally invasive surgery (R-TAMIS) is a novel and evolving technique with limited reported outcomes in the literature. Compared to the laparoscopic approach, R-TAMIS provides enhanced optics, increased degrees of motion, superior ergonomics, and easier maneuverability in the confines of the rectum. We report a single institution experience at a large quaternary referral academic medical center with R-TAMIS using the da Vinci Xi® platform. This is a retrospective review of electronic medical records at the Mayo Clinic from September 2017 to April 2020. It includes all available clinical documentations for patients undergoing R-TAMIS at our institution. Patient demographics, intraoperative data (procedure time, tumor size and distance), complications, and pathology reports were reviewed. A total of 28 patients underwent R-TAMIS. Median follow-up was 23.65 months. Sixteen patients underwent R-TAMIS for endoscopically unresectable rectal polyps, eight for rectal adenocarcinoma, two for rectal gastrointestinal stromal tumor, and two for rectal carcinoid tumor. The mean size of the lesions was 4.1 cm (range 0.2-13.8 cm). The mean location of lesions was 7.8 cm (range 0-16 cm) from the anal verge. The mean operative time was 132.5 ± 46.8 min. There was one 30-day complication, and no deaths. Twenty-three (82%) patients were discharged the day of surgery. R-TAMIS is a safe, feasible, and effective technique for the surgical treatment of a variety of rectal pathology. A hybrid technique can be used for the resecting tumors extending into the anal canal.

Abstract
It is important to understand advances in treatment options for rectal cancer. We attempt to highlight advances in rectal cancer treatment in the form of a systematic review. Early-stage rectal cancer focuses on minimally invasive endoluminal surgery, with importance placed on patient selection as the driving factor for improved outcomes. To achieve a complete pathologic response, various neoadjuvant chemoradiation regimens have been employed. Short-course radiation therapy, total neoadjuvant chemotherapy, and others provide unique advantages with select patient populations best suited for each. With a clinical complete response, a "watch and wait" non-operative surveillance has been introduced with preliminary equivalency to radical resection. Various modalities for total mesorectal excision, such as robotic or transanal, have advantages and can be utilized in select patient populations. Tumors demonstrating solid organ or peritoneal spread, traditionally defined as unresectable lesions conveying a terminal diagnosis, have recently undergone advances in hepatic and pulmonary metastasectomy. Hepatic and pulmonary metastasectomy has demonstrated clear advantages in 5-year survival over standard chemotherapy. With the peritoneal spread of colorectal cancer, HIPEC with cytoreductive therapy has emerged as the preferred treatment. Understanding the various therapeutic interventions will pave the way for improved patient outcomes.

Abstract
Low rectal cancer has always posed surgical challenges to gastrointestinal surgeons. Transanal total mesorectal excision (taTME) is a novel approach to radical resection for low rectal cancer. Compared with conventional laparoscopic TME (laTME), taTME is relevant to the benefits of better vision of the mesorectal plane, feasibility of operating in a narrow pelvis, and exact definition of distal resection margin, which may lead to a higher possibility of free circumferential resection margin, better quality of TME specimen, and lower conversion rate. Although there are concerns about its long-term oncological outcomes and complex learning curve, taTME is a promising alternative for rectal cancer. In this review, we discuss the application status and prospects of taTME.

Abstract
Transanal minimally invasive surgery (TAMIS) was first described in 2010 as an alternative to transanal endoscopic microsurgery (TEM). The TAMIS technique can be access to the proximal and mid-rectum for resection of benign and early-stage malignant rectal lesions and also used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery. TAMIS has a shorter learning curve, reduced device setup time, flexibility in instrument use, and versatility in application than TEM. Also, TAMIS shows similar results in a view of the operation time, conversion rate, reoperation rate, and complication to TEM. For these reasons, TAMIS is an easily accessible, technically feasible, and cost-effective alternative to TEM. Overall, TAMIS has enabled the performance of high-quality local excision of rectal lesions by many colorectal surgeons. As TAMIS becomes more broadly utilized such as pelvic abscess drainage, rectal stenosis, and treatment of anastomotic dehiscence, the acquisition of appropriate training must be ensured, and the continued assessment and assurance of outcome must be maintained.

Abstract
BACKGROUND Many transanal platforms have been developed to address the challenge of reach and vision when operating transanally. The single-port robot was specifically designed for narrow-aperture surgery and is a promising platform for minimally invasive transanal surgery. OBJECTIVE The purpose of this phase II trial is to evaluate the safety and feasibility of the initial clinical experience with single-port robot transanal minimally invasive surgery. DESIGN In a prospective phase II trial, patients with rectal neoplasms eligible for local excision were enrolled for single-port robotic transanal minimally invasive surgery. SETTING The study was conducted between October 2018 and March 2020 at a tertiary referral hospital. PATIENTS/INTERVENTION Twenty-six consecutive patients underwent single-port robotic transanal minimally invasive surgery resection of rectal lesions. MAIN OUTCOME MEASURES The primary end point of the study was the efficacy and safety of single-port robotic transanal minimally invasive surgery. RESULTS There were 13 men and 13 women, with an average lesion size of 2.9 cm (range, 1.0-6.0 cm) and average level of 4.8 cm from the anorectal ring (range, 0-30 cm). Ten patients had a preoperative diagnosis of adenocarcinoma, 7 of whom received neoadjuvant chemoradiation (range, 4500-5580 cGy with concurrent oral capecitabine). Eighty-eight percent of cases were completed by single-port robotic transanal minimally invasive surgery; 2 were converted to transanal endoscopic microsurgery, and 1 patient underwent a low anterior resection. There were no piecemeal extractions, and all margins were negative on final pathology. There were no mortalities, and the morbidity rate was 15.4%. There have been no local recurrences, with a mean follow-up of 5.8 months (range, 0-15.9 months). LIMITATIONS The study was limited by small sample size, short-term follow up, and a single-surgeon experience. CONCLUSION Single-port robotic transanal minimally invasive surgery procedures are safe and feasible in patients with select benign and malignant rectal lesions.

Envisioning the future of colorectal surgery: preclinical assessment and detailed description of an endoluminal robotic system (ColubrisMX ELS). Tech Coloproctol 2021; 25:1199-1207. [PMID: 34224035 DOI: 10.1007/s10151-021-02481-0] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Accepted: 06/12/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND The EndoLuminal Surgical System (ELS) is an emerging non-linear robotic system specifically designed for transanal surgery that allows for excision of colorectal neoplasia and luminal defect closure. METHODS An evaluation of ELS was conducted by a single surgeon in a preclinical setting at the EndoSurgical Center of Florida in Orlando, between October 1st, 2020 and December 31st, 2020, using porcine colon as a model. Mock lesions measured 2.5 to 3.5 cm were excised partial-thickness. Specimen quality and excision time was assessed and evaluated. RESULTS Twenty consecutive robotic transanal minimally invasive surgery (TAMIS) operations utilizing the ELS system were successfully performed without fragmentation. The mean and standard deviation procedure time for all 20 cases was 18.41 ± 14.15 min. The latter 10 cases were completed in substantially less time, suggesting that ELS requires at least 10 preclinical cases for a surgeon to become familiar with the technology. A second task, namely suture closure of the partial-thickness defect, was performed in 9 of the 20 cases. Mean time and standard deviation for this task measured 27.89 ± 10.07 min. There were no adverse events. CONCLUSIONS ELS was successful in performing the tasks of partial-thickness disc excision and closure in a preclinical evaluation. Further study is necessary to determine its clinical applicability.

Abstract
Transanal minimally invasive surgery (TAMIS) has gained worldwide acceptance as a means of local excision of early rectal cancers and benign rectal lesions. However, it is technically challenging due to the limitations of rigid laparoscopic instruments in the narrow rectal lumen. Robotic platforms offer improved ergonomics that are valuable in operative fields with limited space. Robotic TAMIS represents an exciting new development that may be more versatile than traditional TAMIS. In this review, we describe the first case of robotic TAMIS performed in our country and a review of current literature on the technique.

Abstract
Removal of rectosigmoid retained foreign bodies (RFB) may require laparoscopy and often laparotomy. Proctoscopic extraction from the distal sigmoid colon and proximal rectum can be technically difficult. Using a transanal minimally invasive surgery (TAMIS) approach, RFBs can be safely removed, avoiding an abdominal operation with associated morbidity. Patients without clinical findings concerning for acute colonic perforation undergo bedside digital rectal examination and proctoscopic attempt at removal of RFB. If unsuccessful, patients undergo rectal examination under anesthesia with proctoscopy and attempted RFB removal. If the RFB cannot be easily removed, a TAMIS port is inserted into the anal canal and pneumorectum is established. A laparoscopic camera and instruments are then used to facilitate removal of the RFB. To date, TAMIS was successful in all 10 patients with RFB requiring an operation. All patients tolerated the procedure well and were discharged to home from the postoperative recovery room. Unfortunately, none of the patients presented for follow-up visits, but there were no known complications. This technique can be considered prior to laparotomy for patients with RFBs after failed digital examination with proctoscopy.

Abstract
INTRODUCTION This study describes the experience with robot-assisted transanal minimally invasive surgery (rTAMIS) at a single institution. TAMIS has become a popular minimally invasive technique for local excision of well-selected rectal lesions. rTAMIS has been proposed as another option as it improves the ergonomics of conventional laparoscopic techniques. METHODS Retrospective case series of patients with rectal lesions who underwent rTAMIS. Patient demographics, final pathology, surgical and admission details, and clinical outcomes were recorded. Successful procedures were defined as having negative margins on final pathology. RESULTS A total of 16 patients underwent rTAMIS by a single surgeon between April 2018 and December 2019. Mean age of patients was 63 years. Final pathologies were negative for tumor (n = 4), tubulovillous adenoma (n = 4), tubulovillous adenoma with high-grade dysplasia (n = 4), and invasive rectal adenocarcinoma (n = 4). 43% were located in the middle rectum and 56% were located in the distal rectum. Mean maximum diameter was 4.1 cm (IQR 2-3.1 cm). Negative margins were seen in 100% of the excision cases, and 100% were intact. Mean operative time was 87 min (IQR 54.8-97.3 min), and median length of stay was 0 days (IQR 0-1 days). Postoperative complications included incontinence (n = 1) and abscess formation (n = 2). rTAMIS provided curative treatment for 12/16 patients, and the remaining 4 patients received the appropriate standard of care for their respective pathologies. CONCLUSIONS Robot-assisted TAMIS is a safe alternative to laparoscopic TAMIS for resection of appropriate rectal polyps and early rectal cancers. rTAMIS may provide a modality for resecting larger or more proximal rectal lesions due to the wristed instruments and superior visualization with the robotic camera. Future studies should focus on comparing outcomes between robotic and laparoscopic TAMIS, and whether rTAMIS allows for the removal of larger, more complex lesions, which may save patients from a more morbid radical proctectomy.

Transanal minimally invasive surgery vs endoscopic mucosal resection for rectal benign tumors and rectal carcinoids: A retrospective analysis. World J Clin Cases 2020; 8:4311-4319. [PMID: 33083390 PMCID: PMC7559669 DOI: 10.12998/wjcc.v8.i19.4311] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2020] [Revised: 07/01/2020] [Accepted: 08/29/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) is a good choice for resection of rectal neoplasms. Endoscopic mucosal resection (EMR) is also widely used in the treatment of benign rectal tumors such as rectal polyps and rectal adenomas. However, no studies have compared the outcome of TAMIS and EMR.
AIM To compare the short-term outcomes after TAMIS and EMR for rectal carcinoid and benign tumors (including rectal polyps and adenomas).
METHODS From January 2014 to January 2019, 44 patients who received TAMIS and 53 patients who received EMR at The Fifth People’s Hospital of Shanghai were selected. Primary outcomes (surgical-related) were operating time, blood loss, length of postoperative hospital stay, rate of resection margin involvement and lesion fragmentation rate. The secondary outcomes were complications such as hemorrhage, urinary retention, postoperative infection and reoperation.
RESULTS No significant differences were observed in terms of blood loss (12.48 ± 8.00 mL for TAMIS vs 11.45 ± 7.82 mL for EMR, P = 0.527) and length of postoperative hospital stay (3.50 ± 1.87 d for TAMIS vs 2.72 ± 1.98 d for EMR, P = 0.065) between the two groups. Operating time was significantly shorter for EMR compared with TAMIS (21.19 ± 9.49 min vs 49.95 ± 15.28 min, P = 0.001). The lesion fragmentation rate in the EMR group was 22.6% (12/53) and was significantly higher than that (0%, 0/44) in the TAMIS group (P = 0.001). TAMIS was associated with a higher urinary retention rate (13.6%, 6/44 vs 1.9%, 1/53 P = 0.026) and lower hemorrhage rate (0%, 0/44 vs 18.9%, 10/53 P = 0.002). A significantly higher reoperation rate was observed in the EMR group (9.4%, 5/53 vs 0%, 0/44 P = 0.036).
CONCLUSION Compared with EMR, TAMIS can remove lesions more completely with effective hemostasis and lower postoperative hemorrhage and reoperation rates. TAMIS is a better choice for the treatment of rectal carcinoids.

Abstract
Transanal minimally invasive surgery (TAMIS) is mainly used for benign tumors of the rectum, but there are few reports on treating malignant tumors of the rectum with a large volume. The aim of this study was to evaluate the feasibility and safety of TAMIS for resection of rectal malignant tumors. A 57-year-old patient was pathologically diagnosed as rectal malignancy before surgery. Computed tomography (CT), magnetic resonance imaging (MRI), fludeoxyglucose-18F (18F-FDG), and endoscopic mucosal biopsy were performed to assess the tumor location and preoperative size. There were no contraindications in all preoperative examinations. We applied TAMIS technology to perform the operation on this patient, And the operative time, the amount of blood loss, the length of hospital stay, the cost of hospital stay, surgical complications, postoperative complications and other relevant data were all collected. The operation was successful, the operation time was 45 min, 10 mL of intraoperative blood loss, and the length of stay was 3 days, a tumor of a maximum diameter of 4 cm being completely removed. There were no related complications or recurrence during postoperative follow-up. The pathological results were tubular villous adenoma with low-grade intraepithelial neoplasia, and a focal area of high-grade intraepithelial neoplasia. The pathological stage was T1N0M0. At 3-month follow-up there were no signs of recurrence. The patient was followed up for 5 years after the operation and there was no tumor recurrence or metastasis in other parts and no other discomfort. TAMIS is less commonly used in rectal malignancies, especially for tumors with larger diameters. We successfully performed complete resection of a 4-cm rectal malignant tumor with TAMIS. Given its low risk, low cost, simple operation, and few complications, TAMIS can be used for more indications of rectum diseases.

Abstract
Background. Transanal minimally invasive surgery (TAMIS) was developed as a less aggressive alternative treatment for rectal lesions. The purpose of this study was to report the results of robotic TAMIS for such patients. Methods. Patients eligible for TAMIS were operated on using the da Vinci robotic surgical system and GelPOINT Path Transanal Access Platform. Patient demographics, lesion characteristics, perioperative data, complications, and follow-up of all patients were recorded retrospectively. Results. Between March 2015 and August 2018, 24 patients underwent robotic TAMIS by using the da Vinci Si or Xi. The median operative time was 129.6 minutes, and the estimated blood loss was minimal. The mean length of hospital stay was 4.6 days, with no operative complications and no 30-day mortality. There were no statistically significant differences in clinical results and pathological outcomes between the 2 generations of da Vinci systems. Conclusions. With the use of robotic technology, transanal local excision for rectal lesions can be performed with relative ease and safety and can be potentially decreasing the morbidity associated with more aggressive surgical techniques.

Abstract
Purpose As robotic surgery is increasingly performed in patients with colorectal diseases, understanding proper port placement for robotic colorectal surgery is necessary. This review summarizes current port placement during robotic surgery for colorectal diseases and provides future perspective on port placements. Methods PubMed were searched from January 2009 to December 2018 using a combination of the search terms “robotic” [MeSH], “colon” [MeSH], “rectum” [MeSH], “colorectal” [MeSH], and “colorectal surgery” [MeSH]. Studies related to port placement were identified and included in the current study if they used the da Vinci S, Si, or Xi robotic system and if they described port placement. Results This review included 77 studies including a total of 3,145 operations. Fifty studies described port placement for left-sided and mesorectal excision; 17, 3, and 7 studies assessed port placement for right-sided colectomy, rectopexy, transanal surgery, respectively; and one study assessed surgery with reduced port placement. Recent literatures show that the single-docking technique included mobilization of the second and third robotic arms for the different parts without movement of patient cart and similar to previous dual or triple-docking technique. Besides, use of the da Vinci Xi system allowed a more simplified port configuration. Conclusion Robot-assisted colorectal surgery can be efficiently achieved with successful port placement without movement of patient cart dependent on the type of surgery and the robotic system.

Abstract
BACKGROUND Rectal neoplasm is one of the most common malignancies worldwide. Screening programs for rectal neoplasm result in early diagnosis and a decrease in disease-related mortality and morbidity. In selected patients, early rectal cancer may be treated with local excision. Owing to poor exposure during conventional transanal excision, transanal minimally invasive surgery (TAMIS) was developed, and TAMIS is feasible for the local excision of selected rectal neoplasms. However, the limited range of motion is a major disadvantage of this operation. Therefore, robotic TAMIS was developed to resolve this issue. This paper describes the surgical outcomes of robotic TAMIS for selected rectal tumors. METHODS The eligibility criteria for robotic TAMIS were as follows: benign neoplasms, early malignancy, complete remission after concurrent chemoradiotherapy, lesions located in the middle or lower rectum, and a lesion size of less than 5 cm. To gain access to the anal canal, a transanal access platform was used, and the da Vinci robotic system was mounted for surgery. Patient characteristics and surgical outcomes were recoded. RESULTS A total of 23 patients were included, and the median tumor size was 2.5 cm (range: 1.1-4.5 cm) on average. The median tumor location was 5 cm (range: 2-8 cm) from the anal verge. The median length of hospital stay was 3 days (range: 1-10 days). No intraoperative complications were reported, and no patient readmission occurred. The median follow-up period was 9.6 months. No recurrent lesion was found in the follow-up period. CONCLUSION Based on the short-term results, robotic TAMIS is a feasible and safe technique for the local excision of selected rectal neoplasms.

Abstract
BACKGROUND Given the significant perioperative risks and costs of total mesorectal excision, minimally invasive transanal surgical approaches have grown in popularity for early rectal cancer and rectal polyps. This article discusses a transanal robotic surgery technique to perform full-thickness resections of benign and malignant rectal neoplasms. OBJECTIVE The purpose of this study was to describe an initial experience with robotic transanal minimally invasive surgery. DESIGN This was a retrospective cohort study of consecutive patients who underwent robotic transanal minimally invasive surgery. SETTINGS The study was conducted at a high-volume colorectal surgery practice with a large health maintenance organization. PATIENTS Patients at Southern California Kaiser Permanente with early rectal cancer and rectal polyps amenable to transanal excision were included. INTERVENTIONS Transanal resection of rectal tumors were removed using robotic transanal minimally invasive surgery. MAIN OUTCOME MEASURES Local recurrence of rectal pathology was measured. RESULTS A total of 58 patients underwent robotic transanal minimally invasive surgery with full-thickness rectal resection by 4 surgeons for the following indications: rectal cancer (n = 28), rectal polyp (n = 18), rectal carcinoid (n = 11), and rectal GI stromal tumor (n = 1). Mean operative time was 66.2 minutes (range, 17-180 min). The mean tumor height from the anal verge was 8.8 cm (range, 4-14 cm), and the mean specimen size was 3.3 cm (range, 1.3-8.2 cm). A total of 57 (98.3%) of 58 specimens were intact, and 55 (94.8%) of 58 specimens had negative surgical margins. At a mean follow-up of 11.5 months (range, 0.3-33.3 mo), 3 patients (5.5%) developed local recurrences, and all underwent successful salvage surgery. LIMITATIONS The study was limited by being a retrospective, nonrandomized trial with short follow-up. CONCLUSIONS Robotic transanal minimally invasive surgery is a safe, oncologically effective surgical approach for rectal polyps and early rectal cancers. It offers the oncologic benefits and perioperative complication profile of other transanal minimally invasive surgical approaches but also enhances surgeon ergonomics and provides an efficient transanal rectal platform.

Abstract
Total mesorectal excision (TME) is the gold standard surgical treatment for mid- and low rectal cancer; however, it is associated with specific technical hurdles. Transanal TME (TaTME) is a new procedure developed to overcome these difficulties, through an enhanced visualization of the dissection plane. This potentially could result in a more accurate distal dissection with a lower rate of positive circumferential resection margins, increasing the rate of sphincter-saving procedures. The indications for TaTME are currently expanding, despite not being yet standardized, and structured training programs are ongoing to help overcome the steep learning curve related to the technique. The procedure is feasible and safe with similar intraoperative complications and readmission rates when compared with conventional open or laparoscopic TME. Favorable short-term oncologic results have been reported: in particular, TaTME is associated with mesorectal specimen of a better quality and a longer distal resection margin that is established at the beginning of the procedure under direct view. Robotics, when available, will probably overcome the steep learning curve related to the complexity of TaTME. Long-term follow-up and ongoing RCT trials data are awaited regarding functional results, local recurrence and survival, and to facilitate the comparison with standard laparoscopic or robotic rectal resections. The present review is focused on critically analyzing the theoretical benefits and risks of the procedure, its indications, short- and long-term results and future direction in the application of TaTME.

Laparoscopic transanal minimally invasive surgery (L-TAMIS) versus robotic TAMIS (R-TAMIS): short-term outcomes and costs of a comparative study. Surg Endosc 2018; 33:1981-1987. [PMID: 30547391 DOI: 10.1007/s00464-018-6502-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2018] [Accepted: 10/11/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) has gained worldwide popularity as a method for the local excision of rectal neoplasms. However, it is technically demanding due to limited working space. Robotic TAMIS offers potential enhanced dexterity and ability while allowing for a more aggressive resection with a stable platform. The objective of this study was to review a single institution experience between laparoscopic (L-TAMIS) and robotic TAMIS (R-TAMIS) for treatment of rectal neoplasms and determine if there are significant differences on outcomes. METHODS Forty consecutive patients with rectal neoplasms underwent L-TAMIS or R-TAMIS by two colorectal surgeons from January 2012 to April 2017. We retrospectively reviewed a prospectively maintained database to analyze demographics, peri-operative data, pathology, post-operative complications, and cost. RESULTS There were no significant differences between L- and R-TAMIS on patient demographics. R-TAMIS showed a statically significant increase in cost of surgery by $880. Median direct cost of L-TAMIS was $3562 compared to $4440.92 for R-TAMIS (p = 0.04). Wider range of total duration for L-TAMIS is likely due to the variability of body habitus and location of rectal neoplasm, which can significantly limit L-TAMIS compare to R-TAMIS. There was a trend toward decreased blood loss in the R-TAMIS group. Mortality was 0% in both groups. CONCLUSIONS After reviewing our experience, we conclude there is no significant difference between L- and R-TAMIS other than total direct cost. We confirmed that both L- and R-TAMIS are safe and associated with low morbidity. The limitations of this study include its small sample size. In the future, we hope to show promising data on R-TAMIS with increased sample size and experience, which may allow for transanal resection not previously feasible. Studies with long-term follow-up assessing oncological and functional results will be mandatory.

Abstract
As the field of surgery advances, new approaches have allowed surgeons additional flexibility to perform further interventions with minimal or no external incisions. For many years, single site access (SSA) has been used for transanal procedures, and platforms allowing modified endoscopic approaches have been available. These platforms have limitations related to access, visualization, dexterity, camera control, and instrumentation. Recently, surgical robotics companies have developed and introduced new technologies and platforms, which may help address some of these limitations. Comprehensive internet, open access, and medical and industry conference reviews of robotic surgery platforms and technology available for use in SSA surgery were conducted and 30 articles were found using keywords "robotic surgery, transanal, single site, robotic transanal surgery". A PubMed, Medline, Journals @OVID and open access search for data related to these platforms and technologies was also performed yielding 11 articles. Abstracts were reviewed for those written in the English language, leaving 40 articles which were then filtered for those pertaining to robotic surgery, transanal. 58 abstracts were found, duplicates were eliminated, and the remaining 35 articles were read in their entirety by two reviewers. Several new and existing platforms are identified for use in SSA surgery for transanal surgery as well as abdominal and transoral surgery. These are reviewed, including brand, features, approved and suggested uses, and potential limitations. New robotic technologies serve to enhance the ability of surgeons to perform SSA surgery. This next generation of robotic surgery technology overcomes some of the limitations of preceding endoscopic SSA surgery technology and will enhance the advancement of robotic transanal surgery, but outcomes and performance data are still limited.

Abstract
BACKGROUND Full-thickness local excision (FTLE) for rectal cancer showing clinical complete remission (cCR) after neoadjuvant chemoradiation therapy (NCRT) is associated with good oncological results. The purpose of this study was to report the results of robotic transanal minimally invasive surgery for such patients. METHODS Patients were treated with a 5-fluorouracil-based NCRT regimen. The determination of cCR was based on digital rectal examination, colonoscopy, and magnetic resonance imaging. RESULTS Six patients underwent transanal FTLE using the da Vinci Xi surgical system. The median operative time was 106.5 minutes, and the estimated blood loss was minimal. The mean length of hospital stay was 4.2 days. After 18.2 months of follow-up, none of the patients developed local recurrences or distant disease. CONCLUSIONS With the use of robotic technology, FTLE can be performed with relative ease and can be considered as a viable alternative to radical resection or a "Watch and Wait" strategy.

Abstract
BACKGROUND Transanal minimally invasive surgery (TAMIS) offers intra-luminal full-thickness excision of rectal neoplasia. Robotic TAMIS (RT) allows for greater versatility in motion while operating in the limited space of the rectum. We present our experience with this technique in practice using the DaVinci Xi™ platform. METHOD This is a multi-institutional retrospective analysis for patient undergoing Robotic TAMIS for resection of rectal lesions at two tertiary referral hospitals in the United States. Morbidity, mortality, anatomic measurement, and final pathology were analyzed. RESULTS Thirty-four patients planned for Robotic TAMIS were identified. Average follow-up was 188 days. The average BMI was 29.5 ± 5.9. All patients had an American Society of Anesthesiologist (ASA) Class of 2 or greater and 21 (62%) were ASA 3 or greater. Rectal lesions located from 2 to 15 cm from the dentate line were successfully resected. Lesions up to 4.5 cm in the longest dimension were successfully resected. The average operative time was 100 ± 70 min, which correlated to a robotic console time of 76 ± 67 min. Patients were placed in Lithotomy in 32 (94%) cases and were prone in only 2 (6%) cases. There were no intraoperative complications or conversions to another technique. The only postoperative complication was a medically managed Clostridium difficile infection in 1 patient. Three patients were upstaged to T2 on final pathology and underwent successful formal resections. BMI was a statistically significant predictor of a longer operation. CONCLUSIONS With increased reach and operative range of motion, Robotic TAMIS is a safe and effective method for excising low-risk rectal neoplasia with a wide range of anatomical measurements. Higher BMI is a significant predictor of a longer and likely more challenging operation.

Abstract
Robotic transanal minimally invasive surgery (TAMIS) (RT) represents a compelling new alternative capable of overcoming the limitations of conventional TAMIS for the local excision of rectal lesions. We describe our RT technique using the dVXi™ (Intuitive Surgical, Sunnyvale, CA, USA) which we have used to efficiently and completely excise eight cases of rectal lesions which were not endoscopically resectable. We also include a video vignette of the procedure. With the patient in the prone jackknife position, we insert a GelPOINT™ Path Transanal Access Platform (Applied Medical, Rancho Santa Margarita, CA, USA) in combination with the dVXi and AirSeal™ insufflation system (Conmed, Niagara. Falls, ON, Canada). Our technique aims to be ergonomically efficient to minimise docking difficulties and to reduce instrument clash in the limited space, whilst maximising the capabilities of the dVXi for RT. At 3-month endoscopic follow-up, no evidence of recurrence was detected in any of the eight patients. RT is safe, feasible and has advantages over conventional laparoscopic TAMIS (LT). Our described technique addresses some of the long-standing challenges of LT and the novel RT. The immediate challenge to its widespread use remains the cost, expertise and availability.

Abstract
OBJECTIVES Robotic assisted transanal polipectomy may have advantages compared with the conventional transanal minimally invasive surgery technique. We evaluate the safety, feasibility and advantages of this technique. METHODS Between February 2014 and October 2015, 9patients underwent robotic transanal polypectomy. We performed a retrospective study in which we analyse prospectively collected data regarding patient and tumor characteristics, perioperative outcomes, pathological report, morbidity and mortality. RESULTS A total of 5 male and 4 female patients underwent robotic TAMIS. Lesions were 6,22cm from the anal verge. Mean size was 15,8cm2. All procedures were performed in the lithotomy position. Closure of the defect was performed in all cases. Mean blood loss was 39,8ml. Mean operative time was 71,9min. No severe postoperative complications or readmissions occured. Median hospital stay was 2,5 days. CONCLUSIONS Robotic TAMIS is useful to treat complex rectal lesions. Our transanal platform allowed a wider range of movements of the robotic arms and to perform all procedures in the lithotomy position.

Abstract
BACKGROUND Transanal local excision (TLE) has become the treatment of choice for benign and early-stage selected malignant tumors. However, closure of the rectal wall defect remains a controversial point and the available literature still remains unclear. Our aim was to determine through a systematic review of the literature and a meta-analysis of relevant studies whether or not the wall defect following TLE of rectal tumors should be closed. METHODS Medline and the Cochrane Trials Register were searched for trials published up to December 2016 comparing open versus closed management of the surgical rectal defect after TLE of rectal tumors. Meta-analysis was performed using Review Manager 5.0. RESULTS Four studies were analyzed, yielding 489 patients (317 in the closed group and 182 in the open group). Meta-analysis showed no significant difference between the closed and open groups regarding the overall morbidity rate (OR 1.26; 95% CI 0.32-4.91; p = 0.74), postoperative local infection rate (OR 0.62; 95% CI 0.23-1.62; p = 0.33), postoperative bleeding rate (OR 0.83; 95% CI 0.29-1.77; p = 0.63), and postoperative reintervention rate (OR 2.21; 95% CI 0.52-9.47; p = 0.29). CONCLUSIONS This review and meta-analysis suggest that there is no difference between closure or non-closure of wall defects after TLE.

Abstract
INTRODUCTION Transanal minimally invasive surgery (TAMIS) is an endoscopic operating platform for local excision of rectal neoplasms. However, it may be technically demanding, and its learning curve has yet to be adequately defined. The objective of this study was to determine the number of TAMIS procedures for the local excision of rectal neoplasm required to reach proficiency. METHODS AND PROCEDURES All TAMIS cases performed from 07/2009 to 12/2016 at a single high-volume tertiary care institution for local excision of benign and malignant rectal neoplasia were identified from a prospective database. A cumulative summation (CUSUM) analysis was performed to determine the number of cases required to reach proficiency. The main proficiency outcome was rate of margin positivity (R1 resection). The acceptable and unacceptable R1 rates were defined as the R1 rate of transanal endoscopic microsurgery (TEM-10%) and traditional transanal excision (TAE-26%), which was obtained from previously published meta-analyses. Comparisons of patient, tumor, and operative characteristics before and after TAMIS proficiency were performed. RESULTS A total of 254 TAMIS procedures were included in this study. The overall R1 resection rate was 7%. The indication for TAMIS was malignancy in 57%. CUSUM analysis reported that TAMIS reached an acceptable R1 rate between 14 and 24 cases. Moving average plots also showed that the mean operative times stabilized by proficiency gain. The mean lesion size was larger after proficiency gain (3.0 cm (SD 1.5) vs. 2.3 cm (SD 1.3), p = 0.008). All other patient, tumor, and operative characteristics were similar before and after proficiency gain. CONCLUSIONS TAMIS for local excision of rectal neoplasms is a complex procedure that requires a minimum of 14-24 cases to reach an acceptable R1 resection rate and lower operative duration.

Abstract
Transanal endoscopic surgery (TES) techniques encompass a variety of approaches, including transanal endoscopic microsurgery and transanal minimally invasive surgery. These allow a surgeon to perform local excision of rectal lesions with minimal morbidity and the potential to spare the need for proctectomy. As understanding of the long-term outcomes from these procedures has evolved, so have the indications for TES. In this study, we review the development of TES, its early results, and the evolution of new surgical techniques. In addition, we evaluate the most recent research on indications and outcomes in rectal cancer.

Abstract
BACKGROUND The aim of this study was to evaluate the feasibility, safety, perioperative morbidity, and short-term outcomes of the transanal minimally invasive surgery (TAMIS) technique. METHODS This is a descriptive review of prospectively collected data from 32 consecutive patients who underwent TAMIS procedures in our colorectal unit over a 40-month period. GelPOINT Path port was used in all cases. Demographic data, indications, tumor characteristics, morbidity, and follow-up data were collected. Primary endpoints included feasibility, safety, perioperative morbidity, and resection quality. RESULTS Fifteen adenomas, 12 carcinomas, 1 gastrointestinal stromal tumor, and 1 neuroendocrine tumor were locally excised. Additionally, 3 pelvic abscesses were drained transanally using the TAMIS port. Mean distance from the anal verge was 5.6 ± 1.5 cm. Early postoperative complications occurred in 22%, with only one case of major complication (3.1%) requiring reoperation, and no postoperative mortality. Four carcinomas were understaged (33.3%) and 1 adenoma overstaged (6.7%) preoperatively. Three carcinomas were not suspected preoperatively (25%). Microscopic positive lateral margin was found in one case, and no affected deep margin was found. Fragmentation rate was 6.9%, 2 cases, both lesions over 20 cm2. In cases of fit patients with high-risk carcinomas, 2 underwent immediate salvage surgery and another 2 refused and were treated with adjuvant radiotherapy. With a median follow-up of 26 months, the overall recurrence rate was 10.3%, 1 adenoma and 2 carcinomas. CONCLUSION TAMIS seems to be a safe and reproducible procedure for local excision of well-selected rectal lesions with low morbidity and good functional outcomes.

Abstract
Over the past few decades, robotic surgery has developed from a futuristic dream to a real, widely used technology. Today, robotic platforms are used for a range of procedures and have added a new facet to the development and implementation of minimally invasive surgeries. The potential advantages are enormous, but the current progress is impeded by high costs and limited technology. However, recent advances in haptic feedback systems and single-port surgical techniques demonstrate a clear role for robotics and are likely to improve surgical outcomes. Although robotic surgeries have become the gold standard for a number of procedures, the research in colorectal surgery is not definitive and more work needs to be done to prove its safety and efficacy to both surgeons and patients.

Abstract
A transanal approach to rectal polyp and cancer excision is often an appropriate alternative to conventional rectal resection, and has a lower associated morbidity. There has been a steady evolution in the techniques of transanal surgery over the past 30 years. It started with traditional transanal excision and was revolutionized by introduction of transanal endoscopic microsurgery in early 1980s. Introduction of transanal minimally invasive surgery made it more accessible to surgeons around the world. Now robotic platforms are being tried in certain institutions. Concerns have been raised about recurrence rates of cancers with transanal approach and success of subsequent salvage operations.

Abstract
Minimal access surgery has revolutionised colorectal surgery by offering reduced morbidity and mortality over open surgery, while maintaining oncological and functional outcomes with the disadvantage of additional practical challenges. Robotic surgery aids the surgeon in overcoming these challenges. Uptake of robotic assistance has been relatively slow, mainly because of the high initial and ongoing costs of equipment but also because of limited evidence of improved patient outcomes. Advances in robotic colorectal surgery will aim to widen the scope of minimal access surgery to allow larger and more complex surgery through smaller access and natural orifices and also to make the technology more economical, allowing wider dispersal and uptake of robotic technology. Advances in robotic endoscopy will yield self-advancing endoscopes and a widening role for capsule endoscopy including the development of motile and steerable capsules able to deliver localised drug therapy and insufflation as well as being recharged from an extracorporeal power source to allow great longevity. Ultimately robotic technology may advance to the point where many conventional surgical interventions are no longer required. With respect to nanotechnology, surgery may eventually become obsolete.

Abstract
The treatment for rectal cancer and benign rectal lesions continues to progress in the arena of minimally invasive surgery. While surgical excision of the primary mass remains essential for eradication of disease, there has been a paradigm shift towards less invasive resection methods. Local excision is increasing in popularity for its low morbidity and excellent functional results in select patients. Transanal minimally invasive surgery (TAMIS) is a new technology developed to elevate the practice of local excision to state-of-the-art resection. The goal of this article is to evaluate the history, short-term outcomes, and evolution of the TAMIS technique for excision of benign and malignant rectal neoplasia.

Abstract
Transanal minimally invasive surgery (TAMIS) was first described in 2010 as a crossover between single-incision laparoscopic surgery and transanal endoscopic microsurgery (TEM) to allow access to the proximal and mid-rectum for resection of benign and early-stage malignant rectal lesions. The TAMIS technique can also be used for noncurative intent surgery of more advanced lesions in patients who are not candidates for radical surgery. Proper workup and staging should be done before surgical decision-making. In addition to the TAMIS port, instrumentation and set up include readily available equipment found in most operating suites. TAMIS has proven its usefulness in a wide range of applications outside of local excision, including repair of rectourethral fistula, removal of rectal foreign body, control of rectal hemorrhage, and as an adjunct in total mesorectal excision for rectal cancer. TAMIS is an easily accessible, technically feasible, and cost-effective alternative to TEM.

Abstract
Since the advent of laparoscopy, minimally invasive techniques such as single port laparoscopy, robotics, endoscopically assisted laparoscopy, and transanal endoscopic surgery continue to revolutionize the field of colorectal surgery. Transanal natural orifice transluminal endoscopic surgery (NOTES) represents a further paradigm shift by combining the advantages of these earlier techniques to reduce the size and number of abdominal incisions and potentially optimize rectal dissection, especially with respect to performance of an oncologically adequate total mesorectal excision (TME) for rectal cancer. Since the first experimental report of transanal rectosigmoid resection in 2007, the potential impact of transanal NOTES in colorectal surgery has been extensively investigated in experimental models and recently transitioned to clinical application. There have been 14 clinical trials of transanal TME (taTME) for rectal cancer that have demonstrated the feasibility and preliminary oncologic safety of this approach in carefully selected patients, with results comparable to outcomes after laparoscopic and open TME, including cumulative intraoperative and postoperative complication rates of 5.5 and 35.5%, respectively, 97.3% rate of complete or near-complete specimens, and 93.6% rate of negative margins. Transanal NOTES has also been safely applied to proctectomy and colectomy for benign indications. The consensus among published series suggests that taTME is most safely performed with transabdominal assistance by surgeons experienced with laparoscopic TME, transanal endoscopic surgery, and sphincter-preserving techniques including intersphincteric resection. Future applications of transanal NOTES may include evolution to a pure endoscopic transanal approach for TME, colectomy, and sentinel lymph node biopsy for rectal cancer, with a potential role for robotic assistance.

Abstract
Transanal endoscopic surgery (TES) consists of a series of anorectal surgical procedures using different devices that are introduced into the anal canal. TES has been developed significantly since it was first used in the 1980s. The key point for the success of these techniques is how accurately patients are selected. The main indication was the resection of endoscopically unresectable adenomas. In recent years, these techniques have become more widespread which has allowed them to be applied in conservative rectal procedures for both benign diseases and selected cases of rectal cancer. For more advanced rectal cancers it should be considered palliative or, in some controlled trials, experimental. The role of newer endoscopic techniques available has not yet been defined. TES may allow for new strategies in the treatment of rectal pathology, like transanal natural orifice transluminal endoscopic surgery or total mesorectal excision.

Abstract
PURPOSE The aim of this questionnaire survey was to assess the change in treatment modality over time and the current status of clinical outcomes of local treatment in Japanese patients with pathological T1 (pT1) rectal tumors. METHODS A questionnaire survey was conducted by the 81st Congress of the Japan Society for Cancer of the Colon and Rectum. Clinical and pathological outcomes of all eligible patients undergoing local treatment were retrospectively collected from the medical records of each participating hospital. RESULTS A total of 1371 pT1 patients from January 2006 to December 2008 (Period A), and 659 patients in 2013 (Period B) were registered. Approximately 70 % of patients underwent radical surgery in both periods. The rate of patients undergoing laparoscopic surgery increased from 46.5 % in Period A to 84.7 % in Period B. The indications for local excision were comparable with those for endoscopic intervention in 78 % of institutions. The rate of endoscopic submucosal dissection (ESD) increased from 20.1 % in Period A to 37.9 % in Period B, whereas local excision decreased from 36.9 to 24.1 %. Few patients received adjuvant therapy, and approximately 40 % of patients underwent additional surgery in both periods. Local recurrence was observed in 9.2 % of patients in Period A, with the median follow-up period being 59 months. Eighty-two percent of patients with local recurrence underwent salvage surgery. CONCLUSIONS Local treatment with various modalities was properly performed for early rectal cancer. The number of less invasive modalities, such as laparoscopic surgery and ESD, increased between study periods.
