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

ABSTRACT

INTRODUCTION: 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. METHODS: Data from 252 patients undergoing RBS after laparoscopic adjustable gastric banding (LAGB) or laparoscopic sleeve gastrectomy (LSG) between 2005 and 2019, were analyzed at 2 years of follow up. A subgroup analysis of third procedure was also performed. RESULTS: Overall morbidity occurred in 35 patients (37%) in the LSG group and 40 patients (25%) in the LAGB group (p = 0.045). At 2 years of RBS, mean weight was 92.8 ± 26.7 kg, BMI was 33.1 ± 8.56 kg/m2 for patients who had RBS after LSG. When RBS was performed after LAGB, mean weight at 2 years was 90.1 ± 20.7 kg and BMI was 32.5 ± 6.45 kg/m2. TWL for RBS performed after LSG was 12.7 ± 16.4% versus 25.5 ± 10.3% after LAGB (p < 0.001). CONCLUSION: RBS after LSG seems to lead to higher overall morbidity whereas RBS after LAGB lead to more perioperative issues.
