The development of endoscopy and interventional radiology has reduced the need for repeat surgery to manage postoperative complications, thereby reducing morbidity and mortality. Surgical set-ups modify the anatomy and are sometimes difficult for gastroenterologists and radiologists to understand. To improve multidisciplinary management, certain surgical techniques can be adapted to facilitate morphological identification and endoscopic access to the various anastomoses that are a source of complications, particularly at the supra-mesocolic level. The aim of this update is to provide a non-exhaustive list of surgical procedures that can be used to anticipate the endoscopic and radiological management of possible postoperative complications.
