[What is the position of bariatric surgery in the treatment of non-alcoholic steatohepatitis?]

Abstract

Bariatric surgery is indicated for patients with BMI≥35kg/m² and associated steatohepatitis. Bariatric surgery induces NASH disappearance for nearly 80% of patients after 1 year of follow up. Bariatric surgery is associated with low morbidity and mortality if patients are well selected. Bariatric surgery is contraindicated in patients with cirrhosis. Long-term data are needed to determine the risk of recurrence of NASH. The extension of indications for bariatric surgery to patients with BMI less than 35kg/m² will depend on the results of randomized trials.
