What this Trial Is About
The aim of the study is to demonstrate the superiority of bariatric surgery on the disappearance of NASH without worsening of fibrosis in comparison to medical standard treatment in obese patients (35 kg/m² \> BMI ≥ 30 kg/m²) with NASH complicated of advanced fibrosis (F3 and F4 fibrosis grade according to Brunt score).
