Abstract
Abstract The increasing prevalence of bariatric surgery has resulted in a rise in the number of redo procedures as well. While redo bariatric surgery has demonstrated its effectiveness, there is still a subset of patients who may not derive any benefits from it. This poses a significant challenge for bariatric surgeons, especially when there is a lack of clear guidelines. The primary objective of this study is to evaluate the outcomes of patients who underwent Re-Redo bariatric surgery. We conducted a retrospective cohort study on a group of 799 patients who underwent redo bariatric surgery between 2010 and 2020. Among these patients, 20 individuals underwent a second elective redo bariatric surgery (Re-Redo) because of weight regain (15 patients) or insufficient weight loss, i.e. < 50% EWL (5 patients). Mean BMI before Re-Redo surgery was 38.8 ± 4.9 kg/m 2 . Mean age was 44.4 ± 11.5 years old. The mean %TWL before and after Re-Redo was 17.4 ± 12.4% and %EBMIL was 51.6 ± 35.9%. 13/20 patients (65%) achieved > 50% EWL. The mean final %TWL was 34.2 ± 11.1% and final %EBMIL was 72.1 ± 20.8%. The mean BMI after treatment was 31.9 ± 5.3 kg/m 2 . Complications occurred in 3 of 20 patients (15%), with no reported mortality or need for another surgical intervention. The mean follow-up after Re-Redo was 35.3 months. Although Re-Redo bariatric surgery is an effective treatment for obesity, it carries a significant risk of complications.
