All subjects underwent a complete medical history and physi¬cal examination. Physical examination included measurements of height and weight. Subjects with a body mass index (BMI) ≥ 30 kg/m2 were considered obese. Laboratory tests included white blood cell (WBC) count, serum albumin, alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, amylase, lipase, total cholesterol, triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), and high-sensitivity C-reactive protein (hsCRP).
In order to analyze the presence and severity of hepatic steatosis, hepatic steatosis index (HSI), US and liver biopsy was used. The hepatic steatosis index (HSI) was calculated as 8 × ALT/AST + BMI +2 (if diabetes) +2 (if female gender). All patients underwent US at the time of operation and 3 months postoperatively. All US procedures were performed by one board-certified radiologist who did not have information about the patients. Procedures were done using an iU22 apparatus (Philips Ultrasound, Bothell, WA, USA) or an EUB-7500 apparatus (Hitachi, Tokyo, Japan) equipped with a 5 MHz convex transducer. For evaluation of fatty liver, the severity of liver echogenicity was categorized. Normal echogenicity was a mild and slightly diffuse increase in hepatic echogenicity with normal visualization of diaphragm and intrahepatic vessels. Moderate echogenicity was a moderately diffuse increase in hepatic echogenicity with slightly impaired visualization of diaphragm and intrahepatic vessels. Severe echogenicity was a marked increase in hepatic echogenicity with poor or nonvisualization of the intrahepatic vessel borders, diaphragm, and posterior segment of the right hepatic lobe.
Each US image was reread by the same radiologist who was blinded to the initial reading 1 month after the initial assessment to assess intraobserver variability. Liver biopsy was performed during cholecystectomy using liver wedge resection in 10 patients who had provided informed consent preoperatively. All specimens were reviewed by two pathologists with single blinded method. Sections were stained with hematoxylin and eosin (H&E) and examined at X40 magnification. Steatosis was divided into four stages using the Brunt criteria.
