Bariatric surgery for severe NASH with advanced liver scarring
This study tests whether bariatric surgery (either sleeve gastrectomy or Roux-en-Y gastric bypass) improves severe nonalcoholic steatohepatitis (NASH) with advanced liver scarring in people who are obese. You may also need liver biopsies to confirm your liver disease before and after treatment.
LilleAges 18–65 - NCT03516968RecruitingPhase 3
