    Abstract:
    BACKGROUND: Studies reporting revisionary options for weight loss failure after Roux-en-Y gastric bypass (RYGB) have been underpowered and lacking long-term data. We have previously shown that short-term (12 mo) and midterm (24 mo) weight loss is achievable with laparoscopic adjustable gastric banding (LAGB) for failed RYGB. The present study represents the largest published series with longest postoperative follow-up of patients receiving salvage LAGB after RYGB failure. OBJECTIVE: To investigate long-term results of salvage gastric banding. SETTING: University Hospital, New York, United States. METHODS: Data were prospectively collected with retrospective review. Baseline characteristics were evaluated and weights at multiple time intervals (before RYGB, before LAGB, each year of follow-up). Additional data included approach (open or laparoscopic), operative time, hospital length of stay, and postoperative complications. RESULTS: A total of 168 patients underwent statistical analysis with 86 patients meeting inclusion for RYGB failure. The mean body mass index before RYGB was 48.9 kg/m2. Before LAGB, patients had an average body mass index of 43.7 kg/m2, with 10.4% total weight loss and 21.4% excess weight loss after RYGB. At 5-year follow-up, patients (n = 20) had a mean body mass index of 33.6 kg/m2 with 22.5% total weight loss and 65.9% excess weight loss. The long-term reoperation rate for complications related to LAGB was 24%, and 8% of patients ultimately had their gastric bands removed. CONCLUSION: The results of our study have shown that LAGB had good long-term data as a revisionary procedure for weight loss failure after RYGB.
