Summary

Background: Non-Alcoholic Steatohepatitis (NASH) represents one of the stages of Non-Alcoholic Fatty Liver Disease (NAFLD) with a very high risk to evolve in cirrhosis and hepato-carcinoma.

Currently, the only diagnostic method is a liver biopsy that remains the gold standard for characterizing liver histologic alterations and fibrosis stages. There is no specific treatment for NASH, in fact no drugs are currently licensed specifically for treating this disease.

Aim: Our aim is to conduct a non-inferiority, randomized-controlled trial (RCT) comparing Roux-en-Y Gastric bypass (RYGB) with an intensive lifestyle modification plan (Very low-calorie diet, VLCD) for the reduction of advanced stages of fibrosis in subjects with obesity and NASH after 25% weight loss.

Conditions

  • NASH With Fibrosis
  • Weight Loss
  • Bariatric Surgery Candidate

Interventions

PROCEDURE

roux -en-y- gastric bypass

Roux-\&-Y Gastric Bypass (RYGB) involves the use of a surgical stapler to create a small and vertically oriented gastric pouch with a volume of 30 ml. The upper pouch is completely divided by the gastric remnant and is anastomosed to the jejunum, 75 cm distally to the Treitz's ligament, through a narrow gastrojejunal anastomosis in a Roux-en-Y fashion. Bowel continuity is restored by an entero-entero anastomosis, between the excluded biliary limb and the alimentary limb, performed at 100 cm from the gastrojejunostomy.

DIETARY_SUPPLEMENT

intensive life style modification

Weight loss will be induced using a VLCD (800-850 kcal/day; 59% carbohydrate, 13% fat, 26% protein, 2% fiber) with replacement meals for 2 months, followed by structured food reintroduction every 2-8 weeks (about 50% carbohydrate, 35% total fat, and 15% protein), and an ongoing structured program with follow-up visits up to 25% body weight loss
