ABSTRACT
BACKGROUND: There are reported variations in the intraoperative management of Crohn's disease. This consensus statement aimed to develop a standardised protocol for photographic documentation of intraoperative findings and critical procedural steps in ileocolonic Crohn's disease surgery. METHODS: Colorectal surgeons with a specialist interest in minimally invasive surgery and inflammatory bowel disease were invited as committee members to develop a survey on the use of photo-documentation in Crohn's disease surgery. A 15 item survey was developed on ethical considerations and applications of photo-documentation in audit and quality control, research, and training. RESULTS: There was strong agreement on the potential application of intraoperative photo-documentation in Crohn's disease for training, research, quality control and tertiary referrals. Reviewers agreed that intraoperative staging required photo-documentation of strictures, skip lesions, perforations, fat wrapping and mesenteric disease. The necessary steps to be photo-documented were very specific to Crohn's disease surgery, such as views of anastomosis and strictureplasties, and extent of resection(s). CONCLUSIONS: Our consensus statement identified several items for appropriate intraoperative photo-documentation in Crohn's disease surgery, to be used as an adjunct to accurate annotation of intraoperative findings and procedures.

AIM: The choice of whether to perform protective ileostomy (PI) after anterior resection (AR) is mainly guided by risk factors (RFs) responsible for the development of anastomotic leakage (AL). However, clear guidelines about PI creation are still lacking in the literature and this is often decided according to the surgeon's preferences, experiences or feelings. This qualitative study aims to investigate, by an open-ended question survey, the individual surgeon's decision-making process regarding PI creation after elective AR. METHOD: Fifty four colorectal surgeons took part in an electronic survey to answer the questions and describe what usually led their decision to perform PI. A content analysis was used to code the answers. To classify answers, five dichotomous categories (In favour/Against PI, Listed/Unlisted RFs, Typical/Atypical, Emotions/Non-emotions, Personal experience/No personal experience) have been developed. RESULTS: Overall, 76% of surgeons were in favour of PI creation and 88% considered listed RFs in the question of whether to perform PI. Atypical answers were reported in 10% of cases. Emotions and personal experience influenced surgeons' decision-making process in 22% and 49% of cases, respectively. The most frequently considered RFs were the distance of the anastomosis from the anal verge (96%), neoadjuvant chemoradiotherapy (88%), a positive intraoperative leak test (65%), blood loss (37%) and immunosuppression therapy (35%). CONCLUSION: The indications to perform PI following rectal cancer surgery lack standardization and evidence-based guidelines are required to inform practice. Until then, expert opinion can be helpful to assist the decision-making process in patients who have undergone AR for adenocarcinoma.

BACKGROUND: Clinical practice recommendations for the management of acute appendicitis in pregnancy are lacking. OBJECTIVE: To develop an evidence-informed, trustworthy guideline on the management of appendicitis in pregnancy. We aimed to address the questions of conservative or surgical management, and laparoscopic or open surgery for acute appendicitis. METHODS: We performed a systematic review, meta-analysis, and evidence appraisal using the GRADE methodology. A European, multidisciplinary panel of surgeons, obstetricians/gynecologists, a midwife, and 3 patient representatives reached consensus through an evidence-to-decision framework and a Delphi process to formulate the recommendations. The project was developed in an online authoring and publication platform (MAGICapp). RESULTS: Research evidence was of very low certainty. We recommend operative treatment over conservative management in pregnant patients with complicated appendicitis or appendicolith on imaging studies (strong recommendation). We suggest operative treatment over conservative management in pregnant patients with uncomplicated appendicitis and no appendicolith on imaging studies (weak recommendation). We suggest laparoscopic appendectomy in patients with acute appendicitis until the 20th week of gestation, or when the fundus of the uterus is below the level of the umbilicus; and laparoscopic or open appendectomy in patients with acute appendicitis beyond the 20th week of gestation, or when the fundus of the uterus is above the level of the umbilicus, depending on the preference and expertise of the surgeon. CONCLUSION: Through a structured, evidence-informed approach, an interdisciplinary panel provides a strong recommendation to perform appendectomy for complicated appendicitis or appendicolith, and laparoscopic or open appendectomy beyond the 20th week, based on the surgeon's preference and expertise.

BACKGROUND: The European Association of Endoscopic Surgery (EAES) fellowship programme was established in 2014, allowing nine surgeons annually to obtain experience and skills in minimally invasive surgery (MIS) from specialist centres across the Europe and United States. It aligns with the strategic focus of EAES Education and Training Committee on enabling Learning Mobility opportunities. To assess the impact of the programme, a survey was conducted aiming to evaluate the experience and impact of the programme and receive feedback for improvements. METHODS: A survey using a 5-point Likert scale was used to evaluate clinical, education and research experience. The impact on acquisition of new technical skills, change in clinical practice and ongoing collaboration with the host institute was assessed. The fellows selected between 2014 and 2018 were included. Ratings were analysed in percentage; thematic analysis was applied to the free-text feedbacks using qualitative analysis. RESULTS: All the fellows had good access to observing in operating theatres and 70.6% were able to assist. 91.2% participated in educational activities and 23.5% were able to contribute through teaching. 44.1% participated in research activities and 41.2% became an author/co-author of a publication from the host. 97.1% of fellows stated that their operative competency had increased, 94.3% gained new surgical skills and 85.7% was able to introduce new techniques in their hospitals. 74.29% agreed that the clinical experience led to a change in their practices. The most commonly suggested improvements were setting realistic target in clinical and research areas, increasing fellowship duration, and maximising theatre assisting opportunities. Nevertheless, 100% of fellows would recommend the fellowship to their peers. CONCLUSION: EAES fellowship programme has shown a positive impact on acquiring and adopting new MIS techniques. To further refine the programme, an individualised approach should be adopted to set achievable learning objectives in clinical skills, education and research.

BACKGROUND: Evidence and practice recommendations on the use of transanal total mesorectal excision (TaTME) for rectal cancer are conflicting. OBJECTIVE: We aimed to summarize best evidence and develop a rapid guideline using transparent, trustworthy, and standardized methodology. METHODS: We developed a rapid guideline in accordance with GRADE, G-I-N, and AGREE II standards. The steering group consisted of general surgeons, members of the EAES Research Committee/Guidelines Subcommittee with expertise and experience in guideline development, advanced medical statistics and evidence synthesis, biostatisticians, and a guideline methodologist. The guideline panel consisted of four general surgeons practicing colorectal surgery, a radiologist with expertise in rectal cancer, a radiation oncologist, a pathologist, and a patient representative. We conducted a systematic review and the results of evidence synthesis by means of meta-analyses were summarized in evidence tables. Recommendations were authored and published through an online authoring and publication platform (MAGICapp), with the guideline panel making use of an evidence-to-decision framework and a Delphi process to arrive at consensus. RESULTS: This rapid guideline provides a weak recommendation for the use of TaTME over laparoscopic or robotic TME for low rectal cancer when expertise is available. Furthermore, it details evidence gaps to be addressed by future research and discusses policy considerations. The guideline, with recommendations, evidence summaries, and decision aids in user-friendly formats can also be accessed in MAGICapp: https://app.magicapp.org/#/guideline/4494 . CONCLUSIONS: This rapid guideline provides evidence-informed trustworthy recommendations on the use of TaTME for rectal cancer.

OBJECTIVE: Declining number of applicants and high attrition of residents are a dire reality. Surgeons in training are confronted to various stressors which interfere with their performance and may promote burnout. This study measures stress levels of Swiss surgical residents. METHODS: Swiss surgery residents taking the Surgical Basic Exam from 2016 to 2020 completed the Perceived Stress Scale 10 (PSS). The PSS measures how unpredictable, uncontrollable, and overloaded the respondents evaluate their work life. Scores up to 13 are normal, and scores around 20 are highly pathologic. High subscores of helplessness (PH) and lower subscores of self-efficacy (PSE) indicate distress. RESULTS: A total of 1694 questionnaires were evaluated (return rate 95.7%). Resident median (m) age was 29 years, 43.5% were female, and 72.7% of the residents were in their first 2 years of training. Residents reported a high PSS (m = 15), a high PH (m = 9), and an ordinary PSE (m = 5). Females reported worse PSS (p < 0.001), PH (p < 0.001), and PSE (p = 0.036). In multivariable analysis, male sex (p < 0.001), aiming at orthopedic (p = 0.017) or visceral surgery (p = 0.004), and French as mother tongue (p = 0.037) predicted lower stress levels, while graduating from a country not adjacent to Switzerland led to higher stress (p = 0.047). CONCLUSION: Perceived stress levels are high in this prospective and representative cohort study of Swiss surgical residents. Females endured significantly worse stress and helplessness levels than males. These figures are worrisome as they may directly contribute to the declining attractivity of surgical residencies. Detailed sex-specific analysis and correction of stressors are urgently needed to improve residency programs.

AIM: Surgery is indicated in selected patients with inflammatory bowel disease (IBD). However, due to a negative perception, surgery may be delayed, leading to possible unfavourable outcomes. The aim of this work was to investigate patients' perceptions of surgery and the impact on reported outcomes. METHOD: An international multilingual online survey was used to query IBD patients' experiences of surgery, information sources, expectations and concerns, quality of life (QoL) and feelings. RESULTS: The survey was completed by 425 of 510 participants. Crohn's disease was more frequent (61%) than ulcerative colitis (36%). Most patients primarily learned about surgery from their gastroenterologist and were informed of the risks and benefits by the surgeon. In almost one-third of patients indication for surgery was not a shared decision between gastroenterologist and surgeon. Seventy per cent of patients naïve to surgery were not aware of any surgical options. The majority of patients (80%) perceived surgery as the last option after many medical treatments rather than an alternative therapeutic option (20%). Sixteen per cent of patients obtained their primary information from the Internet, while 82.4% used the Internet to obtain additional information. Fear of surgical complications was cited by 73% of patients, while relief from symptoms was indicated by 31%. Most patients coped with their stoma better than expected or as they expected. Negative feelings decreased after surgery, while a lasting improvement in positive feelings and QoL was reported. CONCLUSION: Despite the negative perception of surgery and the delayed involvement of surgeons as a source of information and in the decision-making process, the majority of respondents experienced positive outcomes from surgery, including improvement QoL and acceptance of the stoma.

BACKGROUND: The European Association for Endoscopic Surgery (EAES) strives to be a leader in promoting the development and expansion of minimally invasive surgery (MIS). Part of the association's mission statement is "to become an information hub for all practitioners of MIS". It is therefore important that the education segment of the association continues to be actively monitored and updated to ensure this mission statement is met. This project aimed to understand the trainees requirement in fulfilling this role, and to develop an practical action plan to ensure such requirements are adequately met. METHODS: Two sequential questionnaires were sent to all members of the EAES. The questionnaires sought to understand the demographics of the EAES membership, and their training requirements. This followed a Delphi methodology. The data collected included training status, level of competence in laparoscopic surgery and tools needed for improving laparoscopic skills. RESULTS: Four hundred and sixty-five responded to the first survey, and 209 responded to the second survey. There were 112 trainees (24.1%) in the first round. More than 50% of trainees were less than 8 years from graduation from medical school. Only 162 (34.8%) of respondents performed MIS in more than half their practice. Videos of common procedures were ranked the highest in terms of what trainees required to help improve their laparoscopic skills, followed by e-learning modules. CONCLUSION: There is a significant training gap identified amongst the trainee population of the EAES with regards to MIS training. Trainees were not performing MIS enough for them to feel confident with their skills. The EAES could fulfill this training requirement via expertly curated videos, and e-learning modules written by senior specialists.

BACKGROUND: COVID-19 pandemic presented an unexpected challenge for the surgical community in general and Minimally Invasive Surgery (MIS) specialists in particular. This document aims to summarize recent evidence and experts' opinion and formulate recommendations to guide the surgical community on how to best organize the recovery plan for surgical activity across different sub-specialities after the COVID-19 pandemic. METHODS: Recommendations were developed through a Delphi process for establishment of expert consensus. Domain topics were formulated and subsequently subdivided into questions pertinent to different surgical specialities following the COVID-19 crisis. Sixty-five experts from 24 countries, representing the entire EAES board, were invited. Fifty clinicians and six engineers accepted the invitation and drafted statements based on specific key questions. Anonymous voting on the statements was performed until consensus was achieved, defined by at least 70% agreement. RESULTS: A total of 92 consensus statements were formulated with regard to safe resumption of surgery across eight domains, addressing general surgery, upper GI, lower GI, bariatrics, endocrine, HPB, abdominal wall and technology/research. The statements addressed elective and emergency services across all subspecialties with specific attention to the role of MIS during the recovery plan. Eighty-four of the statements were approved during the first round of Delphi voting (91.3%) and another 8 during the following round after substantial modification, resulting in a 100% consensus. CONCLUSION: The recommendations formulated by the EAES board establish a framework for resumption of surgery following COVID-19 pandemic with particular focus on the role of MIS across surgical specialities. The statements have the potential for wide application in the clinical setting, education activities and research work across different healthcare systems.

Background and objective: No current nationwide consensus exists on pilonidal disease (PD) treatment in Switzerland and Austria. The objective of this study was to assess and compare the spectrum of PD treatment strategies in Switzerland and Austria. Materials and Methods: A survey including 196 certified institutions (Switzerland, N = 99 and Austria, N = 97) was performed. Treatment strategies for both chronic and acute pilonidal disease were investigated, as well as evolution of treatment over the last 20 years. Results: In total, 92 of 196 (47%) hospitals participated in the survey. Recurrence rate (20%) was similar between the two countries. In acute pilonidal disease, a two-stage approach with incision and drainage as the first step was preferred over a one-stage procedure in both countries. In Austria, all patients with chronic pilonidal disease were treated as inpatients, whereas 28% of patients in Switzerland were treated on an outpatient basis (p = 0.0019). Median length of hospital stay was double in Austria (four days) compared to Switzerland (two days; p < 0.001). Primary resection and off-midline closure (p = 0.017) and the use of tissue flaps (p = 0.023) were performed more commonly in Austria than in Switzerland. Minimally invasive techniques were performed more often in Switzerland than in Austria (52% vs. 4%, p < 0.001). Overall, wide excision with secondary wound healing or midline closures declined over the last 20 years. Conclusion: Treatment strategies for chronic PD differ between Austria and Switzerland with more and longer inpatient care in Austria, increasingly minimally invasive approaches in Switzerland, and outdated procedures still being performed in both countries. Overall, heterogeneity of practice dominates in both countries.

OBJECTIVE: To compare techniques for rectal cancer resection. SUMMARY BACKGROUND DATA: Different surgical approaches exist for mesorectal excision. METHODS: Systematic literature review and Bayesian network meta-analysis performed. RESULTS: Twenty-nine randomized controlled trials included, reporting on 6237 participants, comparing: open versus laparoscopic versus robotic versus transanal mesorectal excision. No significant differences identified between treatments in intraoperative morbidity, conversion rate, grade III/IV morbidity, reoperation, anastomotic leak, nodes retrieved, involved distal margin, 5-year overall survival, and locoregional recurrence. Operative blood loss was less with laparoscopic surgery compared with open, and with robotic surgery compared with open and laparoscopic. Robotic operative time was longer compared with open, laparoscopic, and transanal. Laparoscopic operative time was longer compared with open. Laparoscopic surgery resulted in lower overall postoperative morbidity and fewer wound infections compared with open. Robotic surgery had fewer wound infections compared with open. Time to defecation was longer with open surgery compared with laparoscopic and robotic. Hospital stay was longer after open surgery compared with laparoscopic and robotic, and after laparoscopic surgery compared with robotic. Laparoscopic surgery resulted in more incomplete or nearly complete mesorectal excisions compared with open, and in more involved circumferential resection margins compared with transanal. Robotic surgery resulted in longer distal resection margins compared with open, laparoscopic, and transanal. CONCLUSIONS: The different techniques result in comparable perioperative morbidity and long-term survival. The laparoscopic and robotic approaches may improve postoperative recovery, and the open and transanal approaches may improve oncological resection. Technique selection should be based on expected benefits by individual patient.

OBJECTIVE: The aim of this study was to develop an objective and reliable surgical quality assurance system (SQA) for COLOR III, an international multicenter randomized controlled trial (RCT) comparing transanal total mesorectal excision (TaTME) with laparoscopic approach for rectal cancer. BACKGROUND OF SUMMARY DATA: SQA influences outcome measures in RCTs such as lymph nodes harvest, in-hospital mortality, and locoregional cancer recurrence. However, levels of SQA are variable. METHOD: Hierarchical task analysis of TaTME was performed. A 4-round Delphi methodology was applied for standardization of TaTME steps. Semistructured interviews were conducted in round 1 to identify key steps and tasks, which were rated as mandatory, optional, or prohibited in rounds 2 to 4 using questionnaires. Competency assessment tool (CAT) was developed and its content validity was examined by expert surgeons. Twenty unedited videos were assessed to test reliability using generalizability theory. RESULTS: Eighty-three of 101 surgical tasks identified reached 70% agreement (26 mandatory, 56 optional, and 1 prohibited). An operative guide of standardized TaTME was created. CAT is matrix of 9 steps and 4 performance qualities: exposure, execution, adverse event, and end-product. The overall G-coefficient was 0.883. Inter-rater and interitem reliability were 0.883 and 0.986. To enter COLOR III, 2 unedited TaTME and 1 laparoscopic TME videos were submitted and assessed by 2 independent assessors using CAT. CONCLUSION: We described an iterative approach to develop an objective SQA within multicenter RCT. This approach provided standardization, the development of reliable and valid CAT, and the criteria for trial entry and monitoring surgical performance during the trial.

BACKGROUND: To assess the impact of primary tumor resection (PTR) on survival and morbidity in incurable colorectal cancer. METHODS: Systematic literature review and meta-analysis to compare PTR versus primary tumor intact (PTI). RESULTS: Seventy-seven studies were included, reporting on 159,991 participants (94,745 PTR; 65,246 PTI). PTR improved overall survival (hazard ratio [HR] 0.59, P < 0.0001; mean difference [MD] 7.27 months, P < 0.0001), cancer-specific survival (HR 0.47, MD 10.80), and progression-free survival (HR 0.76, MD 1.67). Overall survival remained significantly improved during subgroup analysis of asymptomatic patients (HR 0.69, MD 3.86), elderly patients (HR 0.46, MD 7.71), patients diagnosed after 2000 (HR 0.62, MD 7.29), patients with colon (HR 0.58, MD 6.31) or rectal (HR 0.54, MD 6.88) primary tumor, patients undergoing resection of primary tumor versus non-resectional surgery (NRS) to treat primary tumor complications (HR 0.56, MD 8.72), and of studies with propensity score analysis (HR 0.65, MD 5.68). Overall survival per treatment strategy was: [PTI/chemotherapy] 14.30 months, [PTI/bevacizumab] 17.27 months, [PTR/chemotherapy] 21.52 months, [PTR/bevacizumab] 27.52 months. PTR resulted in 4.5% perioperative mortality and 22.4% morbidity (major adverse events 10.2%, minor 18.5%, reoperation 2.5%, intraabdominal collection/sepsis 2.2%). PTI had 21.7% morbidity (obstruction 14.4%, anemia 11.0%, hemorrhage 1.5%, perforation 0.6%, adverse events requiring surgery 15.8%). NRS resulted in 10.6% perioperative mortality and 21.7% morbidity (major 7.9%, minor 21.7%, reoperation 0.1%). CONCLUSIONS: PTR in patients with incurable colorectal cancer results in a limited improvement of survival without a significant increase in morbidity. PTR should be considered by the multidisciplinary team on an individual patient basis.

BACKGROUND: The management of rectal cancer has evolved over the years, including the recent rise of Transanal Total Mesorectal Excision (TaTME). TaTME addresses the limitations created by the bony confines of the pelvis, bulky tumours, and fatty mesorectum, particularly for low rectal cancers. However, guidance is required to ensure safe implementation and to avoid the pitfalls and potential major morbidity encountered by the early adopters of TaTME. We report a broad international consensus statement, which provides a basis for optimal clinical practice. METHODS: Forty international experts were invited to participate based on clinical and academic achievements. The consensus statements were developed using Delphi methodology incorporating three successive rounds. Consensus was defined as agreement by 80% or more of the experts. RESULTS: A total of 37 colorectal surgeons from 20 countries and 5 continents (Europe, Asia, North and South America, Australasia) contributed to the consensus. Participation to the iterative Delphi rounds was 100%. An expert radiologist, pathologist, and medical oncologist provided recommendations to maximize relevance to current practice. Consensus was obtained on all seven different chapters: patient selection and surgical indication, perioperative management, patient positioning and operating room set up, surgical technique, devices and instruments, pelvic anatomy, TaTME training, and outcomes analysis. CONCLUSIONS: This multidisciplinary consensus statement achieved more than 80% approval and can thus be graded as strong recommendation, yet acknowledging the current lack of high level evidence. It provides the best possible guidance for safe implementation and practice of Transanal Total Mesorectal Excision.

BACKGROUND: Complete mesocolic excision is gradually becoming an established oncologic surgical principle for right hemicolectomy. However, the procedure is technically demanding and carries the risk of serious complications, especially when performed laparoscopically. A standardized procedure that minimizes technical hazards and facilitates teaching is, therefore, highly desirable. METHODS: An expert group of surgeons and one anatomist met three times. The initial aim was to achieve consensus about the surgical anatomy before agreeing on a sequence for dissection in laparoscopic CME. This proposal was evaluated and discussed in an anatomy workshop using post-mortem body donors along with videos of process-informed procedures, leading to a definite consensus. RESULTS: In order to provide a clear picture of the surgical anatomy, the "open book" model was developed, consisting of symbolic pages representing the corresponding dissection planes (retroperitoneal, ileocolic, transverse mesocolic, and mesogastric), vascular relations, and radicality criteria. The description of the procedure is based on eight preparative milestones, which all serve as critical views of safety. The chosen sequence of the milestones was designed to maximize control during central vascular dissection. Failure to reach any of the critical views should alert the surgeon to a possible incorrect dissection and to consider converting to an open procedure. CONCLUSION: Combining the open-book anatomical model with a clearly structured dissection sequence, using critical views as safety checkpoints, may provide a safe and efficient platform for teaching laparoscopic right hemicolectomy with CME.

Colorectal metastases - Current treatment strategies Abstract. In the course of their disease, more than 50 % of patients with colorectal cancer develop metastases. They are most frequently localized in the liver, followed by the peritoneum and the lungs. The therapeutic options and prognosis of colorectal metastases have improved markedly in recent years. Modern treatment concepts are multimodal and are customized for the individual patient by interdisciplinary tumour boards that follow widely recognised guidelines and norms. The recommendation of an appropriate treatment option in metastasized patients by an interdisciplinary panel of experts is of paramount importance. Besides technical possibilities, factors such as comorbidities, medical outcomes, quality of processes as well as patient-related outcome are all crucial in the decision-making process. In most patients diagnosed with distant metastases, the prognosis is determined by the extent of the liver burden. Hereby, the resection of the liver metastases is of utmost importance to improve the prognosis of a patient, since only those individuals who have successfully undergone resection have a chance for long-term disease free-survival. Whether liver metastases are resectable depends on sufficient volume and function of the future liver remnant (FLR). Manipulation of the FLR as well as upfront oncological treatment of metastases improves the resectability rates in patients with an advanced tumor load in the liver. Laparoscopic liver resection improves patient outcomes by reducing pain and results in a shortened hospital stay. Lung resection for pulmonary metastases as well as cytoreductive surgery for peritoneal metastases are important mainstays of modern personalized treatment concepts. However, results of ongoing trials are eagerly awaited to help quantify the prognostic effects of those therapies and assess their true therapeutic value.

BACKGROUND: Single-incision laparoscopy (SIL) and natural orifice translumenal endoscopic surgery (NOTES) aim at reducing surgical access trauma. To monitor the introduction of emerging technologies, the Swiss Association for Laparo- and Thoracoscopic Surgeons launched a database in 2010. The current status of SIL and NOTES in Switzerland is reported, and the techniques are compared. METHODS: The number and type of procedures, surgeon experience, their impressions of performance, conversion, and complications between 2010 and 2015 are described. A survey was used to acquire additional data not included in the registry. RESULTS: Nine centers included 650 procedures. Cholecystectomy (55 %) and sigmoidectomy (26 %) were most prevalent in both techniques. The number of active centers declined from 9 to 2 during the study period. The frequencies of taught procedures were 4 and 43 % for SIL and NOTES (p < 0.001), and surgeon self-estimated impression of performance was perfect in 50 and 89 %, respectively (p < 0.0001). Conversions in total were 3.6 and 5.7 %, respectively, and 1.1 % to open for both techniques. Morbidity was 5 % in SIL and 2.7 % in NOTES, with 0.8 % access-related complications in NOTES and none in SIL (p = 0.29). Of laparoscopic cholecystectomy, sigmoidectomy, and right hemicolectomy, 11.4 and 15.6 % of cases were operated using SIL or NOTES, respectively (p < 0.0001). CONCLUSIONS: Although in selected specialized centers, a considerable proportion of patients were treated using novel techniques, a fading interest of the surgical community in SIL and NOTES was observed. The proportion of SIL and NOTES procedures taught is insufficient and calls for improvement.

BACKGROUND: Despite standardized techniques, anastomotic complications after colorectal resection remain a challenging problem. Among those, anastomotic stricture is a debilitating outcome which often requires multiple interventions and which is prone to recur. The present series investigates the long-term results of endoscopic balloon dilation for stenotic colorectal anastomosis. METHODS: Consecutive patients from a single institution who presented with an anastomotic stenosis after a colorectal resection were identified using a prospective clinical database. Medical records were systematically reviewed to detail patients' outcomes. RESULTS: Over 17 years (1988-2015), 2361 consecutive patients underwent a colorectal anastomosis. Of those, 76 patients (3.2 %) suffered a symptomatic anastomotic stenosis within a median of 5 months (interquartile range (IQR) 2-13) of the index procedure. All stenoses were primarily treated by endoscopic balloon dilation. Median follow-up was 11 years (IQR 7-14). In half the patients, one to two attempts at endoscopic balloon dilation definitively relieved the stenosis. Overall, the median number of endoscopic balloon dilation required was 3 (IQR 2-3). Recurrence rates at 1 year, 3 year, and 5 year were 11, 22, and 25 %, respectively. Median time to recurrence was 12 months (IQR 3-24). Ultimately, two patients (2.6 %) underwent an operation due to failure of endoscopic treatment. All other patients (97.4 %) were treated successfully with endoscopic balloon dilation. A total of 12 patients (15.7 %) suffered a complication from endoscopic dilation. Of those, 11 were minor bleeding and one was a perforation at the level of the anastomosis. All complications were managed conservatively, and no emergency procedure was required as a consequence of attempted endoscopic balloon dilation. CONCLUSION: Endoscopic balloon dilation is a safe approach to effectively relieve an anastomotic stenosis following a colorectal resection.
