Abstract
Background: Bariatric surgery has been shown to produce the most predictable weight loss results, with laparoscopic sleeve gastrectomy (SG) being the most performed procedure as of 2014. However, inadequate weight loss may present the need for a revisional procedure.
Objectives: The aim of this study is to compare the efficacy of laparoscopic resleeve gastrectomy (LRSG) and laparoscopic Roux-en-Y gastric bypass in attaining successful weight loss.
Setting: Public hospital following SG.
Methods: A retrospective analysis was performed on all patients who underwent SG from 2008-2019. A list was obtained of those who underwent revisional bariatric surgery after initial SG, and their demographic characteristics were analyzed.
Results: A total of 2858 patients underwent SG, of whom 84 patients (3%) underwent either a revisional laparoscopic Roux-en-Y gastric bypass (rLRYGB) or LRSG. A total of 82% of the patients were female. The mean weight and body mass index (BMI) before SG for the LRSG and rLRYGB patients were 136.7 kg and 49.9 kg/m2 and 133.9 kg and 50.5 kg/m2, respectively. The mean BMI showed a drop from 42.0 to 31.7 (P < .001) 1 year post revisional surgery for the LRSG group and 42.7 to 34.5 (P < .001) for the rLRYGB group, correlating to an excess weight loss (EWL) of 61.7% and 48.1%, respectively. At 5 years post revisional surgery, LRSG patients showed an increase in BMI to 33.8 (EWL = 45.3%), while those who underwent rLRYGB showed a decrease to 34.3 (EWL = 49.2%). Completeness of follow-up at 1, 3, and 5 years for rLRYGB and LRSG were 67%, 35%, and 24% and 45%, 21%, and 18%, respectively.
Conclusions: Revisional bariatric surgery is a safe and effective method for the management of failed primary SG. LRSG patients tended to do better earlier on; however, it leveled off with those who underwent rLRYGB by 5 years.
