Intraoperative endoscopy prevents technical defect related leaks in laparoscopic Roux-en-Y gastric bypass: A randomized control trial.

Background: Postoperative anastomotic leaks, bleeding and stenosis are major causes of morbidity after laparoscopic Roux-en-Y gastric bypass (LRYGB). Retrospective studies suggest that intraoperative endoscopy reduces the incidence of these complications.

Methods: We conducted a prospective randomized controlled trial in a single institution between March 2013 and January 2016.
