5. Study Description
Brief Summary
The study aims to characterize mitochondrial metabolism in the liver of obesity surgery patients and to study its relationships with hepatic steatosis, inflammation, and fibrosis.
Detailed Description
The study aims to characterize mitochondrial metabolism in the liver of obesity surgery patients and to study its relationships with hepatic steatosis, inflammation, and fibrosis. The protocols involves a per-operative hepatic needle biopsy for mitochondria characterization and histological scoring of steatosis, inflammation, and fibrosis
