Morbidity Associated with Diverting Loop Ileostomies: Weighing Diversion in Rectosigmoid Resection.

Anterior resection with primary anastomosis is the procedure of choice for patients with rectosigmoid cancers with good sphincter function. Surgeons may perform an associated diverting loop ileostomy (DLI) to minimize the likelihood and/or the severity of an anastomotic leak. To examine the morbidity of DLIs, we performed a review of a prospectively maintained database.

Transanal endoscopic resection with peritoneal entry: a word of caution.

Background: Peritoneal entry during transanal endoscopic microsurgery (TEM) can usually be managed transanally with full-thickness suture closure by experienced operators. The preliminary safety of transanal minimally invasive surgery (TAMIS) has been demonstrated, but the reported experience with upper rectal tumors is limited. The incidence and management of peritoneal entry during transanal endoscopic surgery across various platforms have not been previously evaluated.
