Randomized Controlled Trial Multicenter Study Comparative Study
Surgical Quality Assurance in COLOR III: Standardization and Competency Assessment in a Randomized Controlled Trial.
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. ⋯ 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.

Does A Longer Waiting Period After Neoadjuvant Radio-chemotherapy Improve the Oncological Prognosis of Rectal Cancer?: Three Years' Follow-up Results of the Greccar-6 Randomized Multicenter Trial.
The aim of this study was to report the 3-year survival results of the GRECCAR-6 trial. ⋯ Extending the waiting period by 4 weeks following RCT has no influence on the oncological outcomes of T3/T4 rectal cancers.

Does the Artery-first Approach Improve the Rate of R0 Resection in Pancreatoduodenectomy?: A Multicenter, Randomized, Controlled Trial.
To compare the rates of R0 resection in pancreatoduodenectomy (PD) for pancreatic and periampullary malignant tumors by means of standard (ST-PD) versus artery-first approach (AFA-PD). ⋯ Despite theoretical oncological advantages associated with AFA-PD and evidence coming from low-level studies, this multicenter, randomized, controlled trial has found no difference neither in R0 resection rates nor in postoperative complications in patients undergoing ST-PD versus AFA-PD for pancreatic head adenocarcinoma and other periampullary tumors.

The aim of this study was to assess recurrence risk factors following ileocolonic resection (ICR) for Crohn disease (CD) in a nationwide cohort study SUMMARY BACKGROUND DATA:: Recurrence rate after ICR for CD can be up to 60%, but its predictive factors have never been evaluated in large prospective cohort studies. ⋯ Absence of postoperative smoking, CD prophylaxis, and penetrating disease behavior could be independent predictors of reduced postoperative recurrence after ICR for CD. Prophylactic anti-TNF therapy reduces both endoscopic and clinical recurrence rates. It suggests that upfront surgery followed by postoperative anti-TNF therapy is probably the best therapeutic approach for complex CD (penetrating disease behavior).

Minor Hepatectomies: Focusing a Blurred Picture: Analysis of the Outcome of 4471 Open Resections in Patients Without Cirrhosis.
To elucidate minor hepatectomy (MiH) outcomes. ⋯ MiHs had heterogeneous outcomes. Mortality was low, but MiHs could be stratified according to severe morbidity, bile leak, and liver failure rates. Some MiHs had postoperative outcomes similar to RH.
