Outcome following resectional gastric bypass for failed bariatric surgery

PurposeAn increasing number of patients who have failed a primary bariatric procedure are presenting for revisional surgery. There are few studies examining the outcome following any revisional surgery, and none examining resectional gastric bypass (RGB) in this role. We examine the indications, outcome, and patient satisfaction following conversion of a prior bariatric procedure to the RGB.MethodsFrom May 1992 to May 1998, 38 patients underwent RGB as a conversion from prior bariatric operations. Weight loss, indications, and complications were reviewed. A patient survey was used to examine patient satisfaction.ResultsMean body mass index decreased from 46 to 33 kg/m² following revision to RGB. Median weight loss after revision to RGB was 34 kg. From the time of the initial bariatric procedure to post-RGB, mean body mass index decreased from 52 to 33 kg/m². Patients with pre-RGB Visick scores of 3 or 4 improved following RGB. Ninety-five percent of respondents were satisfied with the RGB, and 85% thought it improved their lives. Constant nausea and vomiting and failure of weight control were the most common indications for revision.ConclusionsResectional gastric bypass is a safe and effective revisional procedure for patients who have had failed or complicated bariatric surgery.
