Gastric bypass specifically impairs liver parameters as compared with sleeve gastrectomy, independently of evolution of metabolic disorders

摘要

Background: Numerous studies have shown that Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) differently affect metabolic disorders associated with obesity. While bariatric surgery has been shown to improve nonalcoholic fatty liver disease, very few studies have compared liver parameters after both procedures.
