Sleeve gastrectomy significantly improved non-alcoholic fatty liver disease (NAFLD) in obese patients, reversing or reducing steatosis and steatohepatitis within a year. This suggests bariatric surgery is a viable treatment for NAFLD, preventing cirrhosis.
Area of Science:
- Hepatology
- Bariatric Surgery
- Metabolic Syndrome
Background:
- Obesity is a primary driver of non-alcoholic fatty liver disease (NAFLD), affecting 66-99% of obese individuals.
- NAFLD can progress to cirrhosis and hepatocellular carcinoma, becoming a leading cause for liver transplantation.
- Sleeve gastrectomy (SG) is the most common bariatric procedure, yet data on its impact on NAFLD is limited.
Purpose of the Study:
- To prospectively evaluate the one-year evolution of NAFLD in obese patients following sleeve gastrectomy.
- To assess the efficacy of SG in managing NAFLD and its associated histological changes.
Main Methods:
- Prospective analysis of 63 obese patients undergoing SG with intraoperative liver biopsy.
- Repeat liver biopsy and analysis of metabolic markers (BMI, weight loss, liver function, lipids, glucose) at 12 months in 43 patients.
Main Results:
- 100% of patients showed improvement or reversal of steatosis and steatohepatitis after 12 months.
- Statistically significant improvements were observed in both steatosis and steatohepatitis.
- One patient experienced complete regression of cirrhosis; no patients showed worsening liver histology.
Conclusions:
- Laparoscopic sleeve gastrectomy effectively manages NAFLD in obese patients, preventing progression to cirrhosis.
- SG demonstrates satisfactory results for NAFLD and metabolic syndrome within 12 months.
- NAFLD should be considered a formal indication for bariatric surgery.
