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. Methods Patients with body mass index (BMI) 50–60 kg/m 2 were randomly assigned to a proximal (150 cm alimentary limb) or a distal (150 cm common channel) gastric bypass. The biliopancreatic limb was 50 cm in both operations. Patients and follow-up personnel were blinded to the type of procedure. Thirty-day outcomes including complications are reported. Results We operated on 115 patients, of whom two were excluded at surgery, leaving 56 and 57 patients in the proximal group and distal group, respectively. The median (range) operating time was 72 (36–151) and 101 (59–227) min, respectively ( p
