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

Bariatric surgery is currently the most efficient technique to treat severe obesity. The 2 surgical procedures most commonly performed in the world are sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) because they induce remission or amelioration of obesity-related co-morbidities in a majority of cases with an acceptable rate of complications. Notably, numerous studies have shown that these procedures improve nonalcoholic fatty liver disease (NAFLD), which has a particularly high prevalence in obese patients (and thus in candidates for bariatric surgery), reaching 86% on preoperative liver biopsies [1].
