Prevalence of Liver Steatosis and Fibrosis and the Diagnostic Accuracy of Ultrasound in Bariatric Surgery Patients

摘要

Background Liver steatosis can progress to fibrosis, cirrhosis, and eventually to end-stage liver disease and hepatocellular carcinoma. We thus determined the prevalence of liver steatosis and fibrosis in patients undergoing bariatric surgery using liver biopsy. We also determined the suitability of ultrasound for diagnosis of liver steatosis with and without simultaneously considering patient characteristics.
