Laparoscopic One-Anastomosis Gastric Bypass with Band-Separated Gastric Pouch (OAGB-BSGP): a Randomized Controlled Trial

One-anastomosis gastric bypass with band-separated gastric pouch (OAGB-BSGP) is a novel “staplerless” version of OAGB. This randomized controlled trial (RCT) compared 2-year outcomes for OAGB-BSGP and standard OAGB. The parallel-group RCT randomly allocated patients to group A, staplerless OAGB-BSGP, or group B, stapled OAGB. Respective mean values for groups A and B (n = 40 each): baseline body mass index (BMI, kg/m2), 40.6 ± 5.6 vs 41.2 ± 6.4...
