Abstract: Objective To evaluate the correlation between low choledochal joint and common bile duct stones(CBDS)by magnetic resonance cholangiopancreatography(MRCP).Methods The clinical data of 129 patients without intrahepatic calculus after cholecystectomy receiving MRCP from March 2008 to August 2009 were retrospectively analyzed.MRCP images and T2WIs were analyzed independently by 2 doctors to classify anatomic variants of cystic duct and calculus.Results CBDS was found in 49 and low insertion of the cystic duct in 31 of the 129 patients(38% vs.24%).For the latter 31 patients, low insertion of the cystic duct with CBDS was found in 17.The analysis showed that low choledochal joint were associated with CBDS(x2 =4.921, P=0.027).Conclusion There is a certain correlation between low insertion of the cystic duct and CBDS.The low insertion of the cystic duct is one of the risk factors for calculus of the common bile duct.
