Roux-en-Y Gastric Bypass, Sleeve Gastrectomy, or One Anastomosis Gastric Bypass As Rescue Therapy After Failed Adjustable Gastric Banding: a Multicenter Comparative Study.

Background: To date, laparoscopic adjustable gastric banding remains the third most commonly performed surgical procedure for weight loss. Some patients fail to get acceptable outcomes and undergo revisional surgery at rates ranging from 7% to 60%. Roux-en-Y gastric bypass (RYGB), one anastomosis gastric bypass (OAGB), and sleeve gastrectomy (SG) are among the most common salvage options for failed laparoscopic adjustable gastric banding. Objective: To compare the outcomes of converting failed laparoscopic adjustable gastric banding to RYGB, OAGB, or SG. Methods: Data collected from 7 experienced bariatric centers around the world were retrospectively collected, reviewed, and analyzed. Final body mass index (BMI), change in BMI, percentage excess BMI loss, and major complications with particular attention to leaks, hemorrhage, and mortality were reported. Results: Of 1219 patients analyzed, 74% underwent RYGB, 16% underwent OAGB, and 10% underwent SG after banding failure. The mean age was 38 years (±10 yr), and 82% of patients were women. The mean follow-up was 33 months. The follow-up rate was 100%, 87%, and 52% at 1, 3, and 5 years, respectively. At the latest follow-up, percentage excess BMI loss >50% was achieved by 75% of RYGB, 85% of OAGB, and 67% of SG patients. Postoperative complications occurred in 13% of patients after RYGB, 5% after OAGB, and 15% after SG. Conclusion: Our data show that it is possible to achieve or maintain significant weight loss with an acceptable complication rate with all 3 surgical options.
