Background: Morbid obesity is now an epidemic with considerable associated morbidity for which bariatric surgery has been the only effective treatment. Despite its success, occasional patients require revision because of weight regain or mechanical complications. The impact of multiple prior bariatric operations on complications and weight loss after revision to Roux-en-Y gastric bypass (RYGBP) was evaluated. Methods: All patients undergoing revisional surgery to RYGBP by the senior author from 1997 through 2004 were retrospectively reviewed at a multi-center academic institution. Patients who had previously undergone multiple revisional operations (MR) were compared to patients who had undergone primary (firsttime) revision (PR). Demographics, indications for revision, complications, and weight loss were reviewed. Results: 66 patients underwent open revision to RYGBP after failed bariatric operations, with 12 in the MR group and 54 in the PR group. Mean preoperative BMI was 46.1 and 45.2 (P=0.8), respectively. Operative time (227 vs 162 min, P=0.07), blood loss (517 vs 313 ml, P=0.09) and hospital length of stay (11.5 vs 6.7 days, P=0.2) were higher in the MR group. Major perioperative complications occurred in 16.7% of MR patients compared to 9.3% of PR patients (P=0.6). Percent of excess weight loss (%EWL) has been 54.3% in the MR group and 60.6% in the PR group (P=0.6). Average follow-up is 26 and 23 months, respectively. Conclusion: Although operative times, blood loss, and LOS were greater in MR patients, RYGBP can be performed in patients with multiple previous bariatric operations with acceptable weight loss and complication rates.
