Feasibility of transient Elastography (Fibroscan®) for the measurement of liver stiffness in morbidly obese patients undergoing bariatric surger

Background: The prevalence of non-alcoholic fatty liver disease (NAFLD) exceeds 90% in severely obese patients undergoing bariatric surgery. A substantial number of these patients may have end-stage liver disease with liver cirrhosis. Fibroscan as a non-invasive diagnostic tool to measure liver stiffness has a good accuracy in various liver diseases. However, few data exist about technical feasibility and accuracy of liver stiffness measurement in these patients at highest risk. Aims: To analyse non-invasive liver stiffness measurement by Fibroscan® in severly obese patients undergoing bariatric surgery compared…
