磁共振胰胆管造影所示胆囊管低位汇合与胆总管结石的关系

摘要

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.%目的 通过磁共振胰胆管造影(MRCP)分析、探讨胆囊管低位汇合与胆总管结石发生的关系.方法 回顾性分析2008年3月至2009年8月进行MRCP检查的胆囊切除术后且无合并肝内胆管结石的129例病人资料.由两位医生独立观察MRCP图像,结合T2WI图像评价胆囊管变异情况及是否存在胆总管结石.结果 所有病例MRCP均能清晰显示胆道系统及胆道结石.129例病人中49例(38%)合并胆总管结石,31例(24%)胆囊管低位汇入胆总管,其中胆囊管低位汇合且合并胆总管结石的为17例(13.2%).胆囊管低位汇入与胆总管结石的发生相关(x2=4.921,P=0.027).结论 胆囊管低位汇入与胆总管结石的发生有一定相关性,胆囊管低位汇入可能是胆总管结石形成的危险因素之一.
