Comparison of diagnostic efficacy of MRCP and ERCP in the management of choledocholithiasis

Abstract

Aim: We compared the accuracy of MRCP and ERCP findings in the management of suspected common bile duct stones. Material and Methods: Between September and December 2017, 104 patients underwent MRCP and then ERCP to explain the etiology of cholestasis and elevated liver enzymes and / or the bilirubin levels. Laboratory values and MRCP were compared with ERCP findings for the accuracy and reliability of laboratory and radiological findings. Results: The one-hundred four patients underwent MRCP and then ERCP. Of these, 49 (47.1%) were males. The mean age of the patients was 60.7 ± 16.4 years. When compared MRCP and ERCP findings, the sensitivity of MRCP was 71%, specificity was 35%, negative predictive value (NPV) was 31% and positive predictive value(PPV) was 75%. The accuracy rate was calculated as 61% Conclusion: The diagnosis of choledocholithiasis, should have been done with primarily MRCP and EUS should be used in cases when MRCP is inadequate. ERCP should be used for only in therapeutic procedures.
