Three risk factors for anastomotic leak have been identified, one is patient-related (ASA score), one is disease-related (rectal location), the third being surgery-related (prolonged operative time). These factors should be considered in perioperative decision-making regarding defunctioning stoma formation.

LESS is an alternative to CL cholecystectomy associated with better cosmesis, body image, QoL and an improved postoperative pain profile.

The authors present one of the first studies comparing open and robotic PD. While it is too early to draw definitive conclusions concerning the long-term outcomes, short-term results show a positive trend in favor of the robotic approach without compromising the oncological principles associated with the open approach.

BackgroundDecreasing anastomotic leak rates remain a major goal in colorectal surgery. Assessing intraoperative perfusion by indocyanine green (ICG) with near‐infrared (NIR) visualization may assist in selection of intestinal transection level and subsequent anastomotic vascular sufficiency. This study examined the use of NIR‐ICG imaging in colorectal surgery.MethodsThis was a prospective phase II study (NCT02459405) of non‐selected patients undergoing any elective colorectal operation with anastomosis over a 3‐year interval in three tertiary hospitals. A standard protocol was followed to assess NIR‐ICG perfusion before and after anastomosis construction in comparison with standard operator visual assessment alone.ResultsFive hundred and four patients (median age 64 years, 279 men) having surgery for neoplastic (330) and benign (174) pathology were studied. Some 425 operations (85·3 per cent) were started laparoscopically, with a conversion rate of 5·9 per cent. In all, 220 patients (43·7 per cent) underwent high anterior resection or reversal of Hartmann's operation, and 90 (17·9 per cent) low anterior resection. ICG angiography was achieved in every patient, with a median interval of 29 s to visualization of the signal after injection. NIR‐ICG assessment resulted in a change in the site of bowel division in 29 patients (5·8 per cent) with no subsequent leaks in these patients. Leak rates were 2·4 per cent overall (12 of 504), 2·6 per cent for colorectal anastomoses and 3 per cent for low anterior resection. When NIR‐ICG imaging was used, the anastomotic leak rates were lower than those in the participating centres from over 1000 similar operations performed with identical technique but without NIR‐ICG technology.ConclusionRoutine NIR‐ICG assessment in patients undergoing elective colorectal surgery is feasible. NIR‐ICG use may change intraoperative decisions, which may lead to a reduction in anastomotic leak rates.

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 Single port access (SPA) surgery is a rapidly evolving field due to the complexity of NOTES (natural orifice translumenal endoscopic surgery). SPA combines the cosmetic advantage of NOTES and possibility to perform surgical procedure with standard laparoscopic instruments. We report a technique of umbilical SPA cholecystectomy using standard laparoscopic instruments and complying with conventional surgical principle and technique of minimally invasive cholecystectomy. Methods Preliminary, prospective experience of SPA cholecystectomy in 11 patients (median age, 46 (range, 27-63) years) scheduled for cholecystectomy was evaluated. Diagnoses for cholecystectomy were: symptomatic gallbladder lithiasis (n = 7), previous acute cholecystitis (n = 3), and biliary pancreatitis (n = 1). Results SPA cholecystectomy was feasible in all patients (median body mass index, 24 (range, 20-34) kg/m 2 ) who were scheduled for preliminary experience using conventional laparoscopic instruments. Median operative time was 52 (range, 40-77) minutes. Intraoperative cholangiography was performed in all patients, except one, and was considered normal. No peroperative or postoperative complications were recorded. Median hospital stay was less than 24 h.Conclusions SPA cholecystectomy is feasible and seems to be safe when performed by experienced laparoscopic surgeons using standard laparoscopic instrumentation. SPA cholecystectomy may be safer than the NOTES approach at this time. It has to be determined whether this approach would benefit patients, other than cosmesis, compared with standard laparoscopic cholecystectomy.

In this study, the posterior approach allows complete resection of low retrorectal tumors, with low morbidity, no incontinence, nearly no recurrence, and no mortality.
