The objective of this study is to compare outcomes of patients who had gastric bypass procedures performed as a rescue procedure for failed gastric banding, with those who had a primary gastric bypass. Materials and methods: The group of patients undergoing revisional gastric bypass for failed gastric band was matched in a 1:2 ratio with control patients who underwent a primary RYGB, based on gender, score, preoperative body mass index, and comorbidities. Data were retrospectively retrieved. Results: Thirty one (33.3%) patients underwent band removal and gastric bypass (group A) and 62 (66.6%) only primary gastric bypass (group B). Nonsignificant differences were seen in operative time, operative bleeding, or length of stay. Complications were more frequent in group A. Postoperative weight at 12-month follow-up was greater in group A, however, not statistically significant. Changes in weight, both absolute, and percentage were not different between groups. This observation was also true for BMI, in which no significant differences were seen. Overall, mean follow-up was 16 ± 3.2 months. Conclusion: Gastric bypass can be performed as revisional bariatric surgery, with low complication rates and acceptable outcomes, though not with the same safety as a primary procedure. Gastric bypass is a satisfactory option for patients with a failed gastric band.
