Revisional surgery after restrictive surgery: midterm outcomes of a tertiary center.

Abstract

Revisional bariatric surgery (RBS) is a challenging type of procedure for the surgeons due to its specific morbidity and efficiency. The RBS has a higher prevalence nowadays and this study may help to improve scarce data upon this specific topic. Data from 252 patients undergoing RBS after laparoscopic adjustable gastric banding (LAGB) or laparoscopic sleeve gastrectomy (LSG) between 2005 and 2019, were analyzed at 2years of follow up. A subgroup analysis of third procedure was also performed. Overall morbidity occurred in 35 patients (37%) in the LSG group and 40 patients (25%) in the LAGB group (p = 0.045). At 2years of RBS, mean weight was 92.8 ± 26.7kg, BMI was 33.1 ± 8.56kg/m2 for patients who had RBS after LSG. When RBS was performed after LAGB, mean weight at 2years was 90.1 ± 20.7kg and BMI was 32.5 ± 6.45kg/m2. TWL for RBS performed after LSG was 12.7 ± 16.4% versus 25.5 ± 10.3% after LAGB (p < 0.001). RBS after LSG seems to lead to higher overall morbidity whereas RBS after LAGB lead to more perioperative issues.
