Compare the Combined Diagnostic Accuracy of Transient Elastography and Visual Liver Score in Assessing Non-Alcoholic Fatty Liver Disease (NAFLD) and Compare it with Liver Biopsy in Morbidly Obese Patients Undergoing Bariatric Surgery: An Observational Study

A liver biopsy is the gold standard for the diagnosis of non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). Here, we combine preoperative transient elastography (TE) and intraoperative standardized visual liver score (VLS) which is compared with intraoperative liver biopsy for prediction of NAFLD and NASH in patients undergoing bariatric surgery. Evaluate the combined diagnostic accuracy of TE and VLS in assessing NAFLD or NASH and compare it with liver biopsy in patients undergoing bariatric surgery. In a prospective cohort of 70 morbidly obese undergoing bariatric surgery, preoperative TE and intraoperative VLS were calculated. Findings of TE and VLS were compared with histology from intraoperative liver biopsy. Histologically, 44 (62.85
