Abstract

Objective To study the value of CT and MRCP in the diagnosis of extrahepatic cholangiolithiasis. Methods A total of 98 cases of patients who suspected of extrahepatic cholangiolithiasis treated in our hospital from July 2016 to January 2018 were selected, and all of them were given abdominal CT and MRCP before operation, and the operative results were taken as criteria to compare the diagnostic value of CT and MRCP in the diagnosis of extrahepatic cholangiolithiasis. Results Among the 98 cases of patients, there were 60 cases of Choledocholithiasis, 7 cases of intrahepatic bile duct stones and 31 cases without stones. The sensitivity, specificity and accuracy in the diagnosis of extrahepatic bile duct stones were 78.33%, 71.05% and 75.51% respectively by CT, and were 91.67%, 81.58% and 87.76% respectively by MRCP. The diagnostic sensitivity and accuracy of CT for extrahepatic bile duct stones were significantly lower than those of MRCP (P<0.05). Conclusion Both of CT and MRCP have high value in the diagnosis of extrahepatic cholangiolithiasis. And MRCP has higher sensitivity and accuracy than CT.
