Abstract
BACKGROUND With steep posterior anorectal angulation, transanal total mesorectal excision (taTME) may have a risk of dissection in the wrong plane or starting higher up, resulting in leaving distal mesorectum behind. Although the distal mesorectal margin can be assessed by preoperative MRI, it needs skilled radiologist and high-definition image for accurate evaluation. This study developed a deep neural network (DNN) to predict the optimal level of distal mesorectal margin. METHODS A total of 182 pelvic MRI images extracted from the cancer image archive (TCIA) database were included. A DNN was developed using gender, the degree of anterior and posterior anorectal angles as input variables while the difference between anterior and posterior mesorectal distances from anal verge was selected as a target. The predictability power was assessed by regression values (R) which is the correlation between the predicted outputs and actual targets. RESULTS The anterior angle was an obtuse angle while the posterior angle varied from acute to obtuse with mean angle difference 35.5°±14.6. The mean difference between the anterior and posterior mesorectal end distances was 18.6±6.6mm. The developed DNN had a very close correlation with the target during training, validation, and testing (R=0.99, 0.81, and 0.89, P<0.001). The predicted level of distal mesorectal margin was closely correlated with the actual optimal level (R=0.91, P<0.001). CONCLUSIONS Artificial intelligence can assist in either making or confirming the preoperative decisions. Furthermore, the developed model can alert the surgeons for this potential risk and the necessity of re-positioning the proctectomy incision.

Peri-operative, oncological and functional outcomes of robotic versus transanal total mesorectal excision in patients with rectal cancer: A systematic review and meta-analysis. Tech Coloproctol 2024; 28:75. [PMID: 38951249 DOI: 10.1007/s10151-024-02947-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Accepted: 05/25/2024] [Indexed: 07/03/2024]
Abstract
BACKGROUND Comparative outcomes of robotic low anterior resection (rTME) and trans-anal total mesorectal excision (TaTME) in patients with low rectal cancer were evaluated. METHODS A systematic online search was conducted using the following databases: PubMed, Scopus, Cochrane database, The Virtual Health Library, Clinical trials.gov and Science Direct. Comparative studies of rTME versus TaTME for low rectal cancer were included. Primary outcomes were postoperative complications, including anastomotic leak, surgical site infection, and Clavien-Dindo complication rate. Total operative time, conversion to open surgery, intra-operative blood loss, intensive therapy unit (ITU) and total hospital length of stay (LOS), oncological outcomes and functional outcomes were the other evaluated outcome parameters. RESULTS A total of 12 studies with a total number of 3025 patients divided between rTME (n = 1881) and TaTME (n = 1144) groups were included. There was no significant difference between the two groups for total operative time (P = 0.39), conversion to open surgery (P = 0.29) and intra-operative blood loss (P = 0.62). Clavien-Dindo ≥ 3 complication rate (P = 0.47), anastomotic leak (P = 0.89), rates of re-operation (P = 0.62) and re-admission (P = 0.92), R0 resections (P = 0.52), ITU LOS (P = 0.63) and total hospital LOS (P = 0.30) also showed similar results between the two groups. However, the rTME group had higher rates of total harvested lymph nodes (P = 0.04) and complete total mesorectal excision (TME) resections (P = 0.05). Albeit with a limited dataset, the Wexner and low anterior resection syndrome (LARS) scores showed better functional results in the rTME group compared with the TaTME group (P = 0.0009 and P = 0.00001, respectively). CONCLUSION Compared with TaTME, rTME seems to provide better functional outcomes, higher lymph node yield and more complete TME resections with a similar post-operative complications profile.

Outcomes of transanal total mesorectal excision compared to laparoscopic total mesorectal excision: A meta-analysis of randomized controlled trials. Surgery 2024; 175:289-296. [PMID: 38001011 DOI: 10.1016/j.surg.2023.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 10/02/2023] [Accepted: 10/24/2023] [Indexed: 11/26/2023]
Abstract
BACKGROUND Transanal dissection is increasingly used in laparoscopic surgery for total mesorectal excision of lower rectal cancers. Several studies compared outcomes of laparoscopic total mesorectal excision with and without transanal dissection, yet there is a paucity of high-quality evidence. This meta-analysis aimed to provide a pooled comparative analysis of outcomes of laparoscopic total mesorectal excision with and without transanal dissection based on evidence from randomized controlled trials. METHODS This Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2022-compliant systematic review of randomized controlled trials compared laparoscopic total mesorectal excision with and without transanal dissection. PubMed, Scopus, and Web of Science were searched through March 2023. The Medical Subject Headings terms used in the search were Rectal neoplasms, Proctectomy, Laparoscopy, and Transanal. The main outcomes included operative and pathologic outcomes. The risk of bias was assessed using the Risk of Bias version 2 tool, and certainty of the evidence was graded using the Grading of Recommendations Assessment, Development, and Evaluation approach. The primary study outcome was conversion to open surgery. RESULTS Four randomized controlled trials (1,339 patients; median age 61.2 years) were included; 671 patients underwent laparoscopic total mesorectal excision with transanal dissection, and 668 underwent laparoscopic total mesorectal excision without transanal dissection. Both groups were similar in age, body mass index, and disease stage, but the laparoscopic total mesorectal excision with transanal dissection group had a higher male-to-female ratio, received neoadjuvant therapy and had a hand-sewn anastomosis more often. Patients who underwent laparoscopic total mesorectal excision with transanal dissection had lower conversion rates (odds ratio = 0.179; P = .001), a higher likelihood of achieving complete total mesorectal excision (odds ratio = 1.435; P = .025), and fewer harvested lymph nodes (weighted mean difference = -1.926; P = .035). The groups had similar operative times (weighted mean difference = -3.476; P = .398), total complications (odds ratio = 0.94; P = .665), major complications (odds ratio = 1.112; P = .66), anastomotic leak (odds ratio = 0.67; P = .432), positive circumferential resection margin (odds ratio = 0.549; P = .155), and positive distal margins (odds ratio = 0.559; P = .171). CONCLUSION Laparoscopic total mesorectal excision with transanal dissection was associated with lower odds of conversion to open surgery, greater likelihood of achieving complete total mesorectal excision, and fewer harvested lymph nodes than laparoscopic total mesorectal excision without transanal dissection.

Surg Endosc 2023; 37:7698-7708.

Abstract
BACKGROUND The effects of minimally invasive total mesoesophageal excision (MITME) on the long-term prognosis of locally advanced esophageal squamous cell carcinoma (ESCC) remain unknown. The objective of this study was to compare the static and dynamic failure patterns of MITME and minimally invasive esophagectomy (MIE) for locally advanced ESCC. METHODS We use propensity score matching (PSM) method to analyze the postoperative failure patterns of the two groups. Cumulative event curves were analyzed for cumulative incidence of failure between different groups, and independent prognostic factors were assessed using time-dependent multivariate analyses. The risk of dynamic failure calculated at 12-month intervals was compared between the two groups using the lifetime table. RESULTS A total of 366 ESCC patients were studied by 1:1 PSM for T stage and TNM stage (MITME group, n = 183; MIE group, n = 183). In the matched cohort, there was significant differences between the MITME and MIE groups in the failure pattern of regional lymph node recurrence (0.5 vs 3.8%, P = 0.032) and non-tumor death (10.9 vs 31.7%, P < 0.001). The cumulative event curve found that the 5-year cumulative failure rate was lower in the MITME group than in the MIE group (3.3 vs 17.1%, P = 0.026) after 5 years of survival. In addition, multivariate Cox regression analysis showed that MIE was an independent poor prognostic factor for a high cumulative failure rate in locally advanced ESCC patients at 5 years after surgery (HR:4.110; 95% CI 1.047-16.135; P = 0.043). The dynamic risk curve showed that the MITME group had a lower risk of failure within 5 years after surgery than the MIE group. CONCLUSION Considering that MITME can significantly improve the postoperative failure pattern and the benefit lasts for at least 5 years, it is feasible to use MITME as a treatment for locally advanced ESCC.

Oncological monitoring after transanal total mesorectal excision (TaTME) for rectal neoplasia. Tech Coloproctol 2023; 27:739-746. [PMID: 36648600 DOI: 10.1007/s10151-023-02755-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 01/06/2023] [Indexed: 01/18/2023]
Abstract
BACKGROUND The surgical treatment of choice for rectal neoplasia is total mesorectal excision (TME). The transanal approach enables a better approach in male and obese patients and/or those with a narrow pelvis and in patients with small tumors. Short-term results are comparable with those for laparoscopy or the open approach, but the medium- and long-term oncological data are sparse. The aim of the present study was to evaluate our early experience with transanal TME (TaTME). METHODS This was a retrospective study conducted on patients who underwent TaTME at our center between August 2013 and April 2017 with a follow-up ≥ 3 years. Histopathology, complications, mortality, neoplastic recurrence and disease-free survival were analyzed. RESULTS One hundred patients (68 men and 32 women,, median age 66.8 years [range 29.6-91.2 years]) were included. There were 67 T3 cases (67%) with 74 N0 cases (74%), the mesorectal quality was graded optimal for 87.6% and only 2 cases of radial margin involvement were detected (2%). The median follow-up period was 47.6 months (range 11.8-78.9 months). Eighteen cases of recurrence were diagnosed, of which 3 (3%) recurred locally with an average disease-free period of 43.1 months. Overall survival was 80% and mortality due to progression of disease was 13%. CONCLUSIONS TaTME is a safe surgical procedure with surgical, anatomopathological and oncological results at 3 years (medium-term) comparable with those for the laparoscopic and open approaches. Better monitoring is required with studies of the long-term functional and quality of life outcomes, i.e., at 5 or 10 years.

Single-stapled anastomosis is associated with a lower anastomotic leak rate than double-stapled technique after minimally invasive total mesorectal excision for MRI-defined low rectal cancer. Surgery 2023; 173:1367-1373. [PMID: 36967334 DOI: 10.1016/j.surg.2023.02.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 01/13/2023] [Accepted: 02/11/2023] [Indexed: 05/21/2023]
Abstract
BACKGROUND After total mesorectal excision, distal rectal transection and anastomosis are critical for short-term, oncological, and functional outcomes, including anastomotic leak. A double-pursestring, single-stapled anastomosis avoids cross-stapling, overcoming the potential drawbacks of transabdominal rectal transection and double-stapled anastomosis. This study aims to compare the anastomotic leak rate in double-stapled and single-stapled anastomoses after minimally invasive total mesorectal excision for magnetic resonance imaging-defined low rectal cancer. METHODS Adult patients (>18 years old) undergoing minimally invasive total mesorectal excision for magnetic resonance imaging-defined low rectal cancer with a stapled low anastomosis (below 5 centimeters from the anal verge) between January 2010 and January 2022 at a single institution were allocated to 2 groups according to the anastomosis: double-stapled (abdominal stapled transection and double-stapled anastomosis) or single-stapled (transanal rectal transection and double-pursestring single-stapled anastomosis). The exclusion criteria were nonrestorative procedures or any type of manual anastomosis. The primary endpoint was the rate of 90-day clinical and radiologic anastomotic leak. RESULTS In total, 185 single-stapled and 458 double-stapled were included. Clinical and tumor characteristics were comparable between the groups. The 90-day anastomotic leak rate was significantly lower in the single-stapled group (6.48% vs 15.28%; P = .002), with similar rates of grade and timing. Thirty- and 90-day complication rates were higher in the double-stapled group (P = .0001; P = .02), with comparable Clavien-Dindo grades. At multivariable analysis, double-stapled anastomosis (P = .01), active smoking (P = .03), and the presence of comorbidities (P = .01) resulted as independent risk factors for an anastomotic leak. CONCLUSION Transanal transection and double-pursestring, single-stapled anastomosis were associated with a lower anastomotic leak rate after minimally invasive total mesorectal excision for magnetic resonance imaging-defined low rectal cancer.

Simultaneous, Multi-Channel, Near-Infrared Fluorescence Visualization of Mesenteric Lymph Nodes Using Indocyanine Green and Methylene Blue: A Demonstration in a Porcine Model. Diagnostics (Basel) 2023; 13:diagnostics13081469. [PMID: 37189570 DOI: 10.3390/diagnostics13081469] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 03/17/2023] [Accepted: 03/24/2023] [Indexed: 05/17/2023] Open
Abstract
Near-infrared fluorescence (NIRF) image-guided surgery is a useful tool that can help reduce perioperative complications and improve tissue recognition. Indocyanine green (ICG) dye is the most frequently used in clinical studies. ICG NIRF imaging has been used for lymph node identification. However, there are still many challenges in lymph node identification by ICG. There is increasing evidence that methylene blue (MB), another clinically applicable fluorescent dye, can also be useful in the intraoperative fluorescence-guided identification of structures and tissues. We hypothesized that MB NIRF imaging could be used for lymph node identification. The aim of this study was to evaluate the feasibility of intraoperative lymph node fluorescence detection using intravenously (IV) administered MB and compare it to ICG via a camera that has two dedicated near-infrared (NIR) channels. Three pigs were used in this study. ICG (0.2 mg/kg) was administered via a peripheral venous catheter followed by immediate administration of MB (0.25 mg/kg). NIRF images were acquired as video recordings at different time points (every 10 min) over an hour using the QUEST SPECTRUM® 3 system (Quest Medical Imaging, Middenmeer, The Netherlands), which has two dedicated NIR channels for simultaneous intraoperative fluorescence guidance. The 800 nm channel was used to capture ICG fluorescence and the 700 nm channel was used for MB. The target (lymph nodes and small bowel) and the background (vessels-free field of the mesentery) were highlighted as the regions of interest (ROIs), and corresponding fluorescence intensities (FI) from these ROIs were measured. The target-to-background ratio (TBR) was then computed as the mean FI of the target minus the mean FI of the background divided by the mean FI of the background. In all included animals, a clear identification of lymph nodes was achieved at all time points. The mean TBR of ICG in lymph nodes and small bowel was 4.57 ± 1.00 and 4.37 ± 1.70, respectively for the overall experimental time. Regarding MB, the mean TBR in lymph nodes and small bowel was 4.60 ± 0.92 and 3.27 ± 0.62, respectively. The Mann-Whitney U test of the lymph node TBR/small bowel TBR showed that the TBR ratio of MB was statistically significantly higher than ICG. The fluorescence optical imaging technology used allows for double-wavelength assessment. This feasibility study proves that lymph nodes can be discriminated using two different fluorophores (MB and ICG) with different wavelengths. The results suggest that MB has a promising potential to be used to detect lymphatic tissue during image-guided surgery. Further preclinical trials are needed before clinical translation.

Abstract
Rectal cancer (RC) is one of the deadliest malignancies worldwide. Surgery is the most common treatment for RC, performed in 63.2% of patients. The type of surgical approach chosen aims to achieve maximum residual function with the lowest risk of recurrence. The selection is made by a multidisciplinary team that assesses the characteristics of the patient and the tumor. Total mesorectal excision (TME), including both low anterior resection (LAR) and abdominoperineal resection (APR), is still the standard of care for RC. Radical surgery is burdened by a 31% rate of major complications (Clavien-Dindo grade 3-4), such as anastomotic leaks and a risk of a permanent stoma. In recent years, less-invasive techniques, such as local excision, have been tested. These additional procedures could mitigate the morbidity of rectal resection, while providing acceptable oncologic results. The "watch and wait" approach is not a globally accepted model of care but encouraging results on selected groups of patients make it a promising strategy. In this plethora of treatments, the radiologist is called upon to distinguish a physiological from a pathological postoperative finding. The aim of this narrative review is to identify the main post-surgical complications and the most effective imaging techniques.

Abstract
Background: In this preliminary experience, the feasibility and effectiveness of surgical training with an animal model for transanal total mesorectal excision (TaTME) were evaluated. Methods: The training was conducted in two experimental animal laboratories in Italy authorized by the Italian Ministry of Health, using female Danish Landrace pigs under the supervision of surgeons with extensive experience in TaTME, animal laboratory training and cadaver laboratory training. The procedure was divided into separate steps, and all the participants were guided step-by-step throughout the entirety of the procedure. Results: During all the editions of the animal laboratory, all the procedures were completed with no major damage to the anatomical structures or intraoperative death of the animals. Live animal tissue is very similar to human tissue, helping trainees improve their tactile feedback. The bleeding effect improved the value of the training and taught the participants how to address this complication. The lack of mesorectal tissue in pigs compared with humans was the main difference. Animal laboratories should not be considered alternatives to cadaver laboratories but as complementary training activities due to their effectiveness and lower costs. Conclusions: Surgical training in animal models for TaTME seems to be effective and could be an opportunity to improve training alongside the use of a cadaver laboratory and proctoring.

Abstract
BACKGROUND Transanal total mesorectal excision (TaTME) is the most recent approach developed to improve pelvic dissection in surgery for mid and low rectal tumors. There are still inconsistencies regarding the technique's oncological results. The aim of this study was to analyze clinical and oncological outcomes of the learning curve of TaTME in comparison to laparoscopic TME (lapTME). METHODS Rectal cancer patients who had TaTME and lapTME in two Portuguese colorectal units between March 2016 and December 2018 were eligible. Primary endpoints were 5-year overall survival, disease-free survival, and local recurrence. Secondary endpoints were clinical and pathological outcomes. RESULTS Forty-four patients underwent TaTME (29 men) and 39 lapTME (27 men) with a median age of 69 and 66 (p = 0.093), respectively. No differences were observed concerning baseline characteristics, emphasizing their comparability. In the TaTME group, there were more hand-sewn anastomosis (0 lapTME versus 7 TaTME, p = 0.018) with significantly less distance to the dentate line (40 mm lapTME versus 20 mm TaTME, p = 0.005) and significantly more loop ileostomies performed (28 lapTME versus 41 TaTME, p = 0.001). There were no differences in post-operative mortality, morbidity, readmissions, and stoma closure. Groups were similar in relation to specimen quality, margins, and resectability; however, TaTME had a significantly higher node yield (14 lapTME versus 20 TaTME, p = 0.002). Finally, no disparities were noted in oncological outcomes, namely local and distant recurrence, 5-year overall survival, and disease-free survival. CONCLUSIONS Even with the disadvantage of the learning curve of a new technique, TaTME appears to be comparable to lapTME, with similar long-term oncological outcomes. It has, however, a demanding learning curve, significant risk for morbidity and should be used only for selected patients.

Abstract
BACKGROUND This study aimed to investigate the safety and efficacy of minimally invasive total mesoesophageal excision (TME) for esophageal cancer. METHODS We retrospectively collected data from patients with esophageal cancer who underwent esophagectomy at our center between January 2011 and June 2017. Among 611 eligible patients, 302 underwent minimally invasive total mesoesophageal excision (the TME group) and 309 underwent non-total mesoesophageal excision (the NME group). Outcomes were compared after 1-to-1 propensity score matching, and subgroup analyses were performed for cases involving pT1-2 or pT3-4a disease. RESULTS The propensity score matching produced 249 pairs of patients. The TME group had a shorter operative time (P < 0.001), lower intraoperative bleeding (P < 0.001), and a shorter postoperative hospital stay (P < 0.001). There were no significant differences between the two groups in the number of removed lymph nodes, 30-day mortality, or postoperative complications. In addition, both groups had similar 3-year rates of overall survival (OS) and disease-free survival (DFS). However, the 3-year recurrence rate in the esophageal bed was significantly lower in the TME group (P = 0.033). Furthermore, among patients with pT3-4a disease, the TME group had better 3-year rates of OS, DFS, and recurrence. CONCLUSION Minimally invasive total mesoesophageal excision appears to be a safe technique that can reduce tumor recurrence in the esophageal bed. Furthermore, this technique provided survival benefits for patients with pT3-4a disease.

Abstract
INTRODUCTION The aims of this study are to evaluate depression and quality of life (QOL) after laparoscopic abdominoperineal resection (LAPR) or transanal total mesorectal excision (TaTME) surgery in low rectal cancer (RC) patients. METHODS This is a prospective observational cohort study. Patients were divided into two groups: either TaTME surgery or LAPR. Psychosocial distress and QOL were assessed using a questionnaire before surgery, at 6 months postsurgery, and 12 months postsurgery. The Hospital Anxiety and Depression Scale was used to assess symptoms of anxiety and depression. The European Organization for Research and Treatment of Cancer-QOL questionnaire core was used to estimate the QOL. RESULTS In the TaTME group, the scores of psychosocial distress and QOL showed an obvious tendency to decrease and then recover. Meanwhile, in the LAPR group, these scores deteriorated significantly at 6 and 12 months, and the recovery was less pronounced. Multivariable analysis suggested that surgical options and tumor stage were significantly associated with psychosocial distress and QOL. CONCLUSION For low RC, TaTME could significantly improve patients' QOL and reduce psychological distress as compared to patients with LAPR at 12 months after surgery.

Abstract
Radiotherapy has been used for more than a hundred years to cure or locally control tumors. Regression of tumors outside of the irradiated field was occasionally observed and is known as the abscopal effect. However, the occurrence of systemic anti-tumor effects was deemed too rare and unpredictable to be a therapeutic goal. Recent studies suggest that immunotherapy and radiation in combination may enhance the abscopal response. Increasing numbers of cases are being reported since the routine implementation of immune checkpoint inhibitors, showing that combined radiotherapy with immunotherapy has a synergistic effect on both local and distant (i.e., unirradiated) tumors. In this review, we summarize pre-clinical and clinical reports, with a specific focus on the mechanisms behind the immunostimulatory effects of radiation and how this is enhanced by immunotherapy.

Abstract
Total mesorectal excision (TME) is the standard surgical treatment for the curative radical resection of rectal cancers. Minimally invasive TME has been gaining ground favored by the continuous technological advancements. New procedures, such as transanal TME (TaTME), have been introduced to overcome some technical limitations, especially in low rectal tumors, obese patients, and/or narrow pelvis. The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME. However, recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series. Robotic TaTME (R-TaTME) has been proposed as a novel technique incorporating the potential benefits of a perineal dissection together with precise control of the distal margins, and also offers all those advantages provided by the robotic technology in terms of improved precision and dexterity. Encouraging short-term results have been reported for R-TaTME, but further studies are needed to assess the real role of the new technique in the long-term oncological or functional outcomes. The present review aims to provide a general overview of R-TaTME by analyzing the body of the available literature, with a special focus on the potential benefits, harms, and future perspectives for this novel approach.

Abstract
BACKGROUND in the literature on rectal cancer (RC) surgery many studies have focused on the quality of total mesorectal excision (TME) dissection, while there is a scarcity of comparative data on transection and anastomosis. No anastomosis has so far proved to be superior to any other. The aim of this study was to compare anastomotic leak (AL) rates between conventional laparoscopic double-stapled (DS), transanal total mesorectal excision (TaTME) and Transanal Transection and Single-Stapled anastomosis (TTSS) techniques. METHODS consecutive mid-low RC patients undergoing elective laparoscopic TME with stapled anastomosis and protective stoma, by either DS, TaTME or TTSS techniques were retrieved from a prospectively collected database. RESULTS 127 DS; 100 TaTME and 50 TTSS were included. Demographics, distance of the tumor from anal verge and neoadjuvant therapy were comparable. Operative time was longer in TaTME over DS and TTSS (p < 0.0001). More 90-days complications occurred in DS group vs TTSS (p = 0.029). The AL rate was 17.5% in DS, 6% in TaTME and 2% in TTSS group (p = 0.005). AL grade was: one B (2%) in TTSS; 2 grade B (2%) and 4 grade C (4%) in TaTME; 6 grade A (4.7%), 7 grade B (5.5%) and 9 grade C (7.1%) in DS group. Reintervention rate after AL was higher in DS group over TTSS (12.6% vs 2%; p = 0.003). The rate of stoma closure, pathology data and margin positivity did not differ. CONCLUSIONS TTSS strategy is feasible, safe and leads to very low AL rates after TME for RC.

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. Future trials will need to evaluate the long-term safety and efficacy of single-port robotic transanal minimally invasive surgery. See Video Abstract at http://links.lww.com/DCR/B605.

Abstract
Purpose This study was performed to evaluate the outcome of implementation of transanal total mesorectal excision (TaTME) for low rectal cancer in a regional hospital and in comparison to laparoscopic (Lap) TME. Methods Consecutive patients with low rectal cancer of which the lowest border of the tumour was located beween 1 and 5 cm from the puborectalis who underwent TME at North District Hospital between January 2013 and December 2019 were included. Clinical, operative, and pathologic outcomes were compared between Lap TME and TaTME. The primary end point was complication profile. Results Thirty-five patients underwent Lap TME and 45 patients underwent TaTME for low rectal cancer. The conversion rate of the TaTME group was significantly lower than that of the Lap TME group (4.4% vs. 20%, P=0.029), but the operating time was longer (259 minutes vs. 219 minutes, P=0.009). The tumour location was significantly lower in the TaTME group, but the distal resection margins were adequate and not different between both groups. The TaTME group had higher incidence rates of prolonged ileus and urinary tract infection, but the other complications were similar between the two groups. The resection margin positivity rates of the TaTME and Lap TME groups were 2.2% and 5.7%, respectively (P=0.670). At a median follow up of 39 months, no abnormal early recurrence was detected. Conclusion It is technically feasible and oncologically safe to perform TaTME in a medium-volume colorectal unit. Patients with difficult pelvic anatomy can benefit by reducing the risk of conversion and margin positivity rate.

Abstract
Lower rectal and anal cancers are distinct from neoplasms involving rest of the rectum. These are relatively difficult to manage owing to important relationships with the sphincter muscles. Involvement of the latter portends a poorer prognosis and increased chance of recurrence. Lymphatic drainage of these tumours is into the systemic circulation and the exact set of lymph nodes involved depends on the precise location of the tumour. The role of imaging includes assessment of local invasion, infiltration of adjacent pelvic organs, assessment of locoregional lymphatic spread and metastasis, post-chemoradiation restaging as well as post-treatment surveillance.

Abstract
Purpose Transanal total mesorectal excision (TaTME) was developed to overcome surgical difficulties experienced in distal pelvic dissection. Concerns have been raised about potential worse postoperative functional outcomes after TaTME. Also, the oncological safety was questioned. This study aimed to describe the functional, surgical, oncological outcomes and quality of life (QoL) after TaTME. Methods All consecutive TaTME cases for rectal cancer without disseminated disease between December 2016 and April 2019 were included. The Wexner incontinence score, low anterior resection syndrome (LARS) score, fecal incontinence-related QoL, and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-core questionnaire and 29-item module (EORTC QLQ-C30/CR29) were collected. Kaplan-Meier analysis was used to calculate local recurrence-free survival. Results Thirty patients were eligible for analysis of which 23 received questionnaires. Response rate was 74%. After a median follow-up of respectively 20.0 and 23.0 months for functional and oncological outcomes, the median (interquartile range) of Wexner incontinence and LARS scores were 9.0 (7.0-12.0) and 33.1 (25.0-39.0). Major LARS was present in 73.3%. Fecal incontinence, general and colorectal-specific QoL subdomains that are associated with poor bowel function scored in line with previously reported data. The 2-year actuarial cumulative local recurrence rate was 3.7% (95% confidence interval, 2.4%-5.0%). Conclusion TaTME may lead to significant functional impairments. Patients should receive preoperative counseling on this topic and be fully aware of the potential consequences of their treatment. Oncological data were in line with other short- to moderate-term data and did not show alarming results.

Abstract
Laparoscopic surgery for rectal cancer is technically challenging. Robotic and transanal TME (TaTME) are both novel approaches developed to provide better visualization and dissection. We aim to combine both approaches in a hybrid procedure and evaluate the feasibility as well as patient and oncological outcomes in this study. A review of a prospectively maintained database of patients who underwent a hybrid abdominal robotic approach with TaTME for rectal cancer between January 2016 and October 2018 was undertaken. Patient demographics, tumor characteristics and surgical outcomes were recorded and analyzed. A total of 69 patients (43 males, 26 females) received this hybrid approach. Their median age was 58 years (range 35-87) with a mean BMI of 24.3 kg/m2 (range 16.4-44.2). Median distance from anal verge was 5 cm (range 2-9). The patients had a median hospital length of stay of 7 days (range 5-28). Complication rate was 17.4% (12 patients) with 3 patients (4.3%) requiring a reoperation. TME quality was optimal with all of them either complete (81.2%) or almost complete (18.8%). 65 patients (94.2%) had an R0 resection with 4 patients (5.8%) with involved circumferential resection margins (≤ 1 mm). The median number of lymph nodes harvested was 20 (range 6-37). After a median follow-up of 27.7 months (range 7-42), local recurrence was identified in 2 patients (4%). Three patients (5.2%) had distant recurrence at the 3-year mark. Hybrid robotic abdominal dissection with transanal TME for rectal cancer appears to be feasible with comparable surgical outcomes to other traditional approaches.

Abstract
Surgery of mid-to-low rectal cancer is still considered challenging. Transanal total mesorectal excision has been proposed to facilitate the mesorectal dissection, gain sphincter-saving procedures, and reduce functional sequelae. Few studies have investigated long-term functional outcomes and patients' quality of life. The aim of this study was to compare functional outcomes and quality of life before and after transanal total mesorectal excision in 1-year follow-up. Between February 2016 and April 2019, 51 patients with mid- or low rectal cancer undergoing transanal total mesorectal excision at Fondazione Policlinico Universitario "A. Gemelli" were enrolled. Neoadjuvant radiochemotherapy was administered to locally advanced cancers. Before and after the surgical procedure, patients were examined collecting clinical data, LARS score, CCFIS, SF36 and FIQL, performing anorectal manometry and endoanal ultrasonography. Thirty-three patients were eligible and completed the 12 months follow-up. After treatment, six patients (18.2%) had minor or major LARS. A mild but significant increase of CCFIS was documented. Only the mean resting pressure significantly decreased at follow-up. No sphincter lesions were documented. FIQL assessment showed significant reduction of lifestyle, coping/behaviour, and embarrassment, while an increase of general health was assessed by SF36. At both uni- and multivariate analyses the neoadjuvant radiochemotherapy had a not negligible impact. Transanal total mesorectal excision represents a safe approach to patients treated for mid- or low rectal cancer. The functional sequelae can be limited in severity, with a low incidence of minor/major LARS, particularly faecal incontinence. These results are comparable to those obtained by the conventional total mesorectal excision.

Abstract
BACKGROUND The surgical approach in rectal cancer treatment has evolved in the last decades and a standardized surgical technique for tumor resection - total mesorectal excision - has been established. SUMMARY In a multidisciplinary effort with the use of total mesorectal excision in combination with adjuvant and neoadjuvant treatments to compliment surgery disease management can achieve excellent long-term local control and improved patient survival. Further improvements in imaging techniques and the ability to identify prognostic factors such as tumor regression, extramural venous invasion, and threatened margins have introduced the concept of decision-making based on preoperative staging information. KEY MESSAGE Therefore, in the modern era treatment algorithms are based on high-resolution imaging to plan neoadjuvant therapy and precision surgery followed by pathological and molecular analysis to stratify patients for the need of adjuvant chemotherapy. Despite excellent results with guideline structured treatment pathways, there is still a need to improve long-term results especially for individuals with locally advanced or metastatic tumors.

Abstract
Despite proven clinical benefits in the short term, technical difficulties limit utilization of laparoscopy in rectal cancer surgery (RCS). Transanal Total Mesorectal Excision (taTME) overcomes many technical limitations of laparoscopic RCS. However, the costs of this procedure have not been addressed yet. Our goal was to perform a comparative cost analysis of taTME and laparoscopic TME (lapTME). Consecutive patients undergoing curative TME between 1 February 2014 and 31 October 2018 were selected from a prospectively maintained database and stratified, according to the type of procedure, into taTME and lapTME groups. Patient demographics, tumour characteristics, operative parameters, and short-term outcomes were analyzed. The main outcome measure was intraoperative costs of the two procedures. Secondary outcomes were short-term outcome and the utilization of hospital resources to manage the postoperative course. Hundred and fifty-two patients with rectal cancer (66 lapTME, 86 taTME) were included in the study. Surgical supplies required for taTME procedure exceeded the cost of lapTME of 754,54 €. The duration of surgery was not significantly different between the two approaches (266 ± 92.85 vs 271 ± 83.63, p = 0.50). Short-term outcomes were comparable including postoperative complication rate (17 vs 20%, p = 0.68), reintervention rate, and length of stay. There was no difference in hospital resources utilization to manage postoperative course including blood test, diagnostics, consultations, and medications. TaTME has higher intraoperative costs in terms of supplies with respect to lapTME. Short-term outcomes and hospital resources to manage postoperative course are comparable.

Abstract
Conventional colectomy, and the Japanese Society for Cancer of the Colon and Rectum (JSCCR) D2 Lymphadenectomy (LND2), are currently considered standard of care for surgical management of colon cancer. Colectomy with complete mesocolic excision (CME) and JSCCR D3 Lymphadenectomy (LND3) are more radical alternative approaches and provide a greater degree of lymph nodal clearance. However, controversy exists over the long-term benefits of CME/LND3 over non-CME colectomies (NCME)/LND2. In this study, we performed a systematic review and meta-analysis to compare the surgical, pathological, and oncological outcomes of CME/LND3 with NCME/LND2. Embase, Medline and CENTRAL databases were searched from inception until May 15, 2020, in accordance with PRISMA guidelines. Studies were included if they compared curative intent CME/LND3 with NCME/LND2. Weighted mean differences (WMD) and odds ratios (OR) were estimated for continuous and dichotomous outcomes respectively. Out of 1310 unique citations, 106 underwent full-text review, and 30 were included for analysis. In total, 21,695 patients underwent resection for colon cancer. 11,625 received CME/LND3, and 10,070 underwent NCME/LND2. No significant differences were found in post-operative morbidity and mortality. Both overall and disease-free survival favored CME/LND3 (5-year OS: OR = 1.29; 95% CI 1.02 to 1.64, p = 0.03; 5-year DFS: OR = 1.61; 95% CI 1.14 to 2.28; p = 0.007). This is the first systematic review and meta-analysis to demonstrate that CME/LND3 has superior long-term survival outcomes compared to NCME/LND2.

Abstract
BACKGROUND To analyze pathologic and perioperative outcomes of laparoscopic vs. open resections for rectal cancer performed over the last 10 years. METHODS A systematic literature search of the following databases was conducted: Cochrane Central Register of Controlled Trials, MEDLINE (through PubMed), EMBASE, and Scopus. Only articles published in English from January 1, 2008 to December 31, 2018 (i.e. the last 10 years), which met inclusion criteria were considered. The review only included articles which compared Laparoscopic rectal resection (LRR) and Open Rectal Resection (ORR) for rectal cancer and reported at least one of the outcomes of interest. The analyses followed the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) statement checklist. Only prospective randomized studies were considered. The body of evidence emerging from this study was evaluated using the Grading of Recommendations Assessment Development and Evaluation (GRADE) system. Outcome measures (mean and median values, standard deviations, and interquartile ranges) were extracted for each surgical treatment. Pooled estimates of the mean differences were calculated using random effects models to consider potential inter-study heterogeneity and to adopt a more conservative approach. The pooled effect was considered significant if p <0.05. RESULTS Five clinical trials were found eligible for the analyses. A positive involvement of CRM was found in 49 LRRs (8.5%) out of 574 patients and in 30 ORRs out of 557 patients (5.4%) RR was 1.55 (95% CI, 0.99-2.41; p = 0.05) with no heterogeneity (I2 = 0%). Incorrect mesorectal excision was observed in 56 out of 507 (11%) patients who underwent LRR and in 41 (8.4%) out of 484 patients who underwent ORR; RR was 1.30 (95% CI, 0.89-1.91; p = 0.18) with no heterogeneity (I2 = 0%). Regarding other pathologic outcomes, no significant difference between LRR and ORR was observed in the number of lymph nodes harvested or concerning the distance to the distal margin. As expected, a significant difference was found in the operating time for ORR with a mean difference of 41.99 (95% CI, 24.18, 59.81; p <0.00001; heterogeneity: I2 = 25%). However, no difference was found for blood loss. Additionally, no significant differences were found in postoperative outcomes such as postoperative hospital stay and postoperative complications. The overall quality of the evidence was rated as high. CONCLUSION Despite the spread of laparoscopy with dedicated surgeons and the development of even more precise surgical tools and technologies, the pathological results of laparoscopic surgery are still comparable to those of open ones. Additionally, concerning the pathological data (and particularly CRM), open surgery guarantees better results as compared to laparoscopic surgery. These results must be a starting point for future evaluations which consider the association between ''successful resection" and long-term oncologic outcomes. The introduction of other minimally invasive techniques for rectal cancer surgery, such as robotic resection or transanal TME (taTME), has revealed new scenarios and made open and even laparoscopic surgery obsolete.

Abstract
Rectal cancer treatment has evolved during the past 40 years with the use of a standardized surgical technique for tumour resection: total mesorectal excision. A dramatic reduction in local recurrence rates and improved survival outcomes have been achieved as consequences of a better understanding of the surgical oncology of rectal cancer, and the advent of adjuvant and neoadjuvant treatments to compliment surgery have paved the way for a multidisciplinary approach to disease management. Further improvements in imaging techniques and the ability to identify prognostic factors such as tumour regression, extramural venous invasion and threatened margins have introduced the concept of decision-making based on preoperative staging information. Modern treatment strategies are underpinned by accurate high-resolution imaging guiding both neoadjuvant therapy and precision surgery, followed by meticulous pathological scrutiny identifying the important prognostic factors for adjuvant chemotherapy. Included in these strategies are organ-sparing approaches and watch-and-wait strategies in selected patients. These pathways rely on the close working of interlinked disciplines within a multidisciplinary team. Such multidisciplinary forums are becoming standard in the treatment of rectal cancer across the UK, Europe and, more recently, the USA. This Review examines the essential components of modern-day management of rectal cancer through a multidisciplinary team approach, providing information that is essential for any practising colorectal surgeon to guide the best patient care.

Abstract
BACKGROUND Minimally invasive surgery is commonly used in the treatment of rectal cancer, despite the lack of evidence to support oncological equivalence or improved recovery compared with open surgery. OBJECTIVE This study aims to analyze prospectively collected data from a large Australasian colorectal cancer database. DESIGN This is a retrospective cohort study using propensity score matching. SETTING This study was conducted using data supplied by the Bi-National Colorectal Cancer Audit. PATIENTS A total of 3451 patients who underwent open (n = 1980), laparoscopic (n = 1269), robotic (n = 117), and transanal total mesorectal excision (n = 85) for rectal cancer were included in this study. MAIN OUTCOME MEASURE The primary outcome was positive margin rates (circumferential resection margin and/or distal resection margin) in patients treated with curative intent. RESULTS Propensity score matching yielded 1132 patients in each of the open and minimally invasive surgery groups. Margin positivity rates and lymph node yields did not differ between groups. The open group had a significantly lower total complication rate (27.6% vs 35.8%, p < 0.0001), including a lower rate of postoperative small-bowel obstruction (1.2% vs 2.5%, p = 0.03). The minimally invasive surgery group had significantly lower wound infection rate (2.9% vs 5.0%, p = 0.02) and a shorter length of hospital stay (8 vs 9 days, p < 0.0001). There was no difference in 30-day mortality. LIMITATIONS Results are limited by the quality of registry data entries. CONCLUSION In this patient population, minimally invasive proctectomy demonstrated similar margin rates in comparison with open proctectomy, with a reduced length of stay but a higher overall complication rate.

Las tasas de positividad del margen y los rendimientos de los ganglios linfáticos no difirieron entre los dos grupos. El grupo abierto tuvo una tasa de complicaciones totales significativamente menor (27.6% vs 35.8%, p <0.0001), incluida una tasa menor de obstrucción postoperatoria del intestino delgado (1.2% vs 2.5%, p = 0.03). El grupo de cirugía mínimamente invasiva tuvo una tasa de infección de la herida significativamente menor (2.9% frente a 5.0%, p = 0,02) y una estancia hospitalaria más corta (8 frente a 9 días, p <0.0001). No hubo diferencias en la mortalidad a los 30 días.Los resultados están limitados por la calidad de la entrada de datos de registro.En esta población de pacientes, la proctectomía mínima invasiva demostró tasas de margen similares en comparación con la proctectomía abierta, con una estadía reducida pero una tasa más alta de complicaciones en general.

Abstract
BACKGROUND Low anterior resection syndrome (LARS) is common following surgery for mid and low rectal cancer. Transanal total mesorectal excision (TaTME) involves intraoperative stretching of the anal sphincter while an anal single port is placed, which can potentially further disturb anorectal function. The aim of our study was to systematically assess anal function after TaTME using anorectal manometry and questionnaires. METHODS Patients who had TaTME for rectal cancer at our institution were prospectively assessed by means of anorectal manometry and the standard LARS score. The primary endpoint was the resting pressure to assess internal sphincter damage and the secondary endpoints were squeeze pressure to assess external anal sphincter and analysis of correlation between LARS score and these two manometry parameters. Patients who had laparoscopic TME (LaTME) served as a control group. RESULTS Out of 81 patients invited to participate 48 accepted. There were 36 in theTaTMEgroup, and 12 in the LaTMEgroup. The mean follow-up time from the index operation date to the assessment date was 41.34 months (± SD 24.834). The mean resting pressure did not differ significantly between the groups (36.44 mmHg ± 18.514 and 36.58 mmHg ± 13.318 in the TaTME and LaTME groups, respectively, p = 0.981). The mean squeeze pressure was also comparable (125.00 mmHg ± 66.141 and 111.83 mmHg ± 51.111 in the TaTME and LaTME groups, respectively, p = 0.533). The mean LARS score was comparable and showed comparable results. The analysis of correlation between LARS score and manometry parameters showed no significant associations between resting or squeeze pressure and L:ARS score. CONCLUSIONS Following TME surgery, the resting and squeeze pressures of the anal sphincter measured by manometry were generally decreased, with no differences between the transanal and laparoscopic approaches.

Abstract
Rectal cancer has always posed surgical challenges to the colorectal surgeon. The quality of the total mesorectal excision (TME) performed is key in determining local disease control. Unlike the great success in adoption of laparoscopic surgery in colon cancer treatment, studies comparing laparoscopy to open rectal surgery all revealed noninferiority was not achieved. Transanal TME (taTME) is the latest advanced technique pioneered to tackle difficult pelvic dissections. The evolution of taTME surgery in recent years was explored in this review. The outcomes to date on the latest literatures are reviewed, included complications, functional outcomes, oncological results and future clinical researches. taTME, while definitely still in its early stages of development, has steadily accumulated safety and feasibility data. It not only provides a better solution to an old problem that colorectal surgeons have been attempting to tackle for quite some time, but also appears to be quite promising in terms of outcomes on numerous fronts. With structured training models, and proctored clinical application, alongside design and implementation of international-scale large multicenter randomized clinical trials, one can only hope that taTME and its innovations will not only open a new era for colorectal surgery, but also for even more surgical disease pathologies.

Abstract
AIM Transection of the distal rectum and subsequent anastomosis differ between the open, minimally invasive and transanal approaches. With the transanal technique, there is direct control of the transection level and the single-stapled anastomosis, thus overcoming two crucial limitations of rectal surgery. This study describes a technique for precise a transanal rectal transection with a single-stapled (TTSS) colorectal, coloanal or ileoanal anastomosis in 20 consecutive patients undergoing low rectal surgery. METHODS After completing rectal dissection by the preferred technique (open or minimally invasive), TTSS was created. The detailed video describes this technique. RESULTS TTSS was feasible in all patients: 13 underwent total mesorectal excision + TTSS for low rectal cancer and seven underwent ileoanal pouch + TTSS for benign disease. Complications included one Grade IIIa and three Grade I, according to the Clavien-Dindo classification (median follow-up 6 months). CONCLUSION TTSS represents a technique which can be applied regardless of the preferred approach (open, minimally invasive or transanal) for low rectal dissection. The adoption of TTSS could well allow for a more consistent comparison of the outcomes following the differing approaches to rectal surgery.

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.

An international multicentre prospective audit of elective rectal cancer surgery; operative approach versus outcome, including transanal total mesorectal excision (TaTME). Colorectal Dis 2018; 20 Suppl 6:33-46.

Abstract
INTRODUCTION Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short-term outcomes of TaTME, open, laparoscopic, and robotic TME internationally. METHODS A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients undergoing elective total mesorectal excision (TME) for malignancy between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary outcome measure was anastomotic leak. RESULTS Of 2579 included patients, 76.2% (1966/2579) underwent TME with restorative anastomosis of which 19.9% (312/1966) had a minimally invasive approach (laparoscopic or robotic) which included a transanal component (TaTME). Overall, 9.0% (175/1951, 15 missing outcome data) of patients suffered an anastomotic leak. On univariate analysis both laparoscopic TaTME (OR 1.61, 1.02-2.48, P = 0.04) and robotic TaTME (OR 3.05, 1.10-7.34, P = 0.02) were associated with a higher risk of anastomotic leak than non-transanal laparoscopic TME. However this association was lost in the mixed-effects model controlling for patient and disease factors (OR 1.23, 0.77-1.97, P = 0.39 and OR 2.11, 0.79-5.62, P = 0.14 respectively), whilst low rectal anastomosis (OR 2.72, 1.55-4.77, P < 0.001) and male gender (OR 2.29, 1.52-3.44, P < 0.001) remained strongly associated. The overall positive circumferential margin resection rate was 4.0%, which varied between operative approaches: laparoscopic 3.2%, transanal 3.8%, open 4.7%, robotic 1%. CONCLUSION This contemporaneous international snapshot shows that uptake of the TaTME approach is widespread and is associated with surgically and pathologically acceptable results.
