Objective To evaluate the diagnostic and therapentic value of ERCP for choledocholithiasis.Methods ERCT and EST in 142 cases with suspected choledoholithiasis were performed for treating choledocholithiasis.All the imaging data were analyzed retrospectively.Results Among 142 cases,128 cases were choledocholithiasis,3 cases were suspected choledocholithiasis,6 cases were normal and 5 cases were miss-diagnosis.The diagnostic accuracy of ERCT was 90.1%(128/142).EST were successful in 129 cases,and 4 cases were failure,the successful rate was 96.9%.Conclusion ERCT is of important value in diaguosing choledocholithiasis and EST is safe and reliable for treating choledocholithiasis.
