Abstract: Objective: To evaluate the clinical value and efficacy of EUS, ERCP and MRCP when comparing these three methods in diagnosis of patients suspected with common bile duct stones (CBDS). Methods: A total of 93 patients suspected with CBDS needing treatment in our hospital were diagnosed with EUS, ERCP and MRCP, which aimed to evaluate three methods’ clinical valuve in CBDS diagnosis. Results: Accuracy rate could be significant increased when combining at least two methods in diagnosis of CBDS. The sensitivity and specificity for EUS was 83.9% and 73.7%, for ERCP was 89.2% and 84.2%, and for MRCP was 93.2% and 100%, respectively. Conclusion: It shown the better choice of MRCP in the diagnosis of CBDS for its great advantage in sensitivity and specificity, when compared to EUS and ERCP. Patients suspected with CBDS could be diagnosed with MRCP firstly, and then the negative with MRCP could be performed with ERCP or EUS for CBDS confirmation.
