Zarshenas N, Tapse LC, Batterham M, et al. - A retrospective study was conducted to correlate clinical data on weight, nutritional disorders, and gastrointestinal symptoms of patients before and following one anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB). Researchers retrieved data on anthropometry, nutritional indices, dietary intake, and gastrointestinal symptoms in cohorts of patients up to 2 years following OAGB and RYGB. In this analysis, 73 individuals had either an RYGB (28) or an OAGB (45), with 71% seeking these as a revisional procedure. The results indicated that significant and similar weight loss results are seen following both OAGB and RYGB. In both cohorts, nutritional disorders were common and increased over time. Nevertheless, more gastrointestinal side effects were observed in OAGB patients, which may contribute to poor quality of life and nutritional consequences. Prospective and longer-term studies were needed to evaluate the nutritional and gastrointestinal health of patients undergoing OAGB.
