Purpose: ARFI is frequently used for non-invasive assessment of liver fibrosis. Some factors were identified impairing the diagnostic accuracy of ARFI elastography. So far, it is unclear whether obstructive cholestasis interferes with ARFI assessment of liver fibrosis. The aim of this prospective study was to evaluate the influence of biliary obstruction and cholangitis on measurement of liver stiffness before and after bile duct drainage. Material and methods: A total of 42 patients (31 male, mean age 60.2 ± 15.6 years) with obstructive cholestasis were consecutively enrolled. 28 patients (67%) had pre-ERCP cho…
