Background: The duodenojejunal bypass liner (DJBL) (Endo Barrier Gastrointestinal Liner) is an endoscopically placed and removable intestinal liner that creates a duodenojejunal bypass resulting in weight loss and improvement in type 2 diabetes mellitus. Objective: Weight loss before bariatric surgery to decrease perioperative complications. Design: Prospective, randomized, sham-controlled trial. Setting: Multicenter, tertiary care, teaching hospitals. Patients: Twenty-one obese subjects in the DJBL arm and 26 obese subjects in the sham arm composed the intent-to-treat population. Interventions: The subjects in the sham arm underwent an EGD and mock implantation. Both groups received identical nutritional counseling. Main Outcome Measurements: The primary endpoint was the difference in the percentage of excess weight loss (EWL) at week 12 between the 2 groups. Secondary endpoints were the percentage of subjects achieving 10% EWL, total weight change, and device safety. Results: Thirteen DJBL arm subjects and 24 sham arm subjects completed the 12-week study. EWL was 11.9% +/- 1.4% and 2.7% +/- 2.0% for the DJBL and sham arms, respectively (P < .05). In the DJBL arm, 62% achieved 10% or more EWL compared with 17% of the subjects in the sham arm (P < .05). Total weight change in the DJBL arm was -8.2 +/- 1.3 kg compared with -2.1 +/- 1.1 kg in the sham arm (P < .05). Eight DJBL subjects terminated early because of GI bleeding (n = 3), abdominal pain (n = 2), nausea and vomiting (n = 2), and an unrelated preexisting illness (n = 1). None had further clinical symptoms after DJBL explantation. Limitations: Study personnel were not blinded. There was a lack of data on caloric intake. Conclusions: The WE achieved endoscopic duodenal exclusion and promoted significant weight loss beyond a minimal sham effect in candidates for bariatric surgery.
