Revisional Adjustable Gastric Band in Roux-en-Y Gastric Bypass—Is It Worth It?

Purpose A subset of patients undergoing Roux-en-Y gastric bypass (RYGB) presents with either insufficient weight loss or weight regain. Data on the revisional restrictive options including laparoscopic adjustable gastric band (LAGB) is scarce. This study analyzes the mid-term efficacy and safety of LAGB as a revisional procedure after RYGB. Methods Data of all patients with revisional LAGB after primary RYGB between January 2011 and May 2019 were retrospectively reviewed. Outcomes included assessment of weight changes, resolution of comorbidities, and early and late complications during the study period. Results Twenty patients were included. The median Body Mass Index (BMI) before revisional LAGB was 34.8 (interquartile range [IQR] 31.9–38.1) kg/m 2 . After a median follow-up of 33.5 (IQR 19.5–76.5) months, the median BMI was 28.7 (IQR 26.1–32.2) kg/m 2 . The median additional Excess Weight Loss (EWL) was 37.6% (IQR 23–44.4), leading to a median total EWL of 79.5% (IQR 54.4–94.6). BMI and EWL post-LAGB improved significantly compared to BMI and EWL pre-LAGB (p
