According to research presented at Digestive Disease Week, in Chicago, IL, bariatric surgery may results in significant improvement in nonalcoholic fatty liver disease (NAFLD).

Researchers from the University of South Florida found that bariatric surgery resolved liver inflammation and reversed early-stage liver fibrosis. Liver biopsies from 152 patients were compared at time of procedure and at an average of 29 months afterwards. Post-operative biopsies revealed resolution of fat deposits on the liver in 70% of patients. Lobular inflammation was resolved in 74% of patients, chronic portal inflammation in 32% of patients, and steatohepatitis resolved in 88% of patients.

Further, 62% of patients with Stage 2 liver fibrosis had an improvement or resolution of the fibrosis and 1 of 3 patients with cirrhosis also demonstrated improvement.

Michel Murr, MD, professor of surgery and director of Tampa General Hospital and USF Health Bariatric Center, suggest that bariatric surgery be considered for patients with a body mass index (BMI) >35 and obesity-related comorbidities, or a BMI >40.
