This study aimed at evaluating the sensitivity and specificity of EUS and TUS compared to ERCP in a cohort of 100 patients. The sensitivity and accuracy of EUS in the diagnosis of common bile duct dilatation were 84% and 83%, i.e. significantly higher (p=0.0001) than TUS (46% and 66%, ). The specificities (82%, 91%) were not significantly different (p=0.218). The sensitivity and accuracy of EUS in the diagnosis of pathological content of the common bile duct were 88% and 92%, i.e. significantly higher (p{0.0001) than TUS (33% and 64%). The specificities (96%, 94%) were not significantly different (p=0.641). The incidence of choledocholithiasis in the high-risk group was significantly higher than in the moderate-risk group (p=0.012). EUS is a method with high sensitivity, specificity. It should therefore be preferred to ERCP in patients with low or moderate risk of choledocholithiasis."@en .
