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

Bariatric surgery is currently the more efficient technique to treat severe obesity. The two 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 comorbidities in a majority of cases with an acceptable rate of complications. Notably, numerous studies have shown that these procedures improve non-alcoholic fatty liver diseases (NAFLD) whose prevalence is particularly high in obese patients and thus in candidates for bariatric surgery, reaching 86% on per-operative liver biopsies [1].
