Perioperative Outcomes of Proximal and Distal Gastric Bypass in Patients with BMI Ranged 50–60 kg/m2—A Double-Blind, Randomized Controlled Trial

Background Proximal Roux-en-Y gastric bypass may not ensure adequate weight loss in superobese patients. Bypassing a longer segment of the small bowel may increase weight loss. The objective of the study was to compare the perioperative outcomes of laparoscopic proximal and distal gastric bypass in a double-blind randomized controlled trial of superobese patients. The study was conducted at two public tertiary care obesity centers in Norway.
