摘　　要：目的应用磁共振胰胆管成像(MRCP)分析肝内胆管变异与肝内胆管结石的相关性。资料与方法搜集429例胆石症患者的MRCP检查资料,评价肝内胆管的解剖类型,并分析其与肝内胆管结石的关系。结果MRCP资料显示肝内胆管变异占总病例数的31.7%,肝内胆管常型占68.3%。在肝内胆管变异的病例中,有肝内胆管结石者58例(42.6%),无肝内胆管结石78例(57.4%);肝内胆管常型的病例中,有肝内胆管结石者77例(26.3%),无肝内胆管结石216例(73.7%)。两组病例发生肝内胆管结石概率的χ2检验结果为:χ2=11.538,P<0.005,差异有显著统计学意义。结论肝内胆管变异者有更高的肝内胆管结石发生率。Objective To analyze the correlation between the variants of the intrahepatic bile ducts and calculus of intrahepatic duct with Magnetic Resonance Cholangiopancreatography（MRCP）.Materials and Methods MRCP data of 429 cases with cholelithiasis were analyzed,the anatomical variant types of the intrahepatic bile ducts and the correlation between the types and calculus of intrahepatic duct were evaluated.Results MRCP demonstrated variants of the intrahepatic bile ducts in 31.7% of all the patients,among the variants of intrahepatic bile,there were 58 cases（42.6%） with calculus of intrahepatic duct and 78 cases（57.4%） without calculus.In normal cases,calculus of intrahepatic duct were seen in 77 cases（26.3%） and there were 216 patients（73.7%）without calculus of intrahepatic duct.The result of χ^2 test of the incidence of calculus of intrahepatic duct between the two group was： χ^2=11.538,P〈0.005.A significant statistical significance was found.Conclusion Patients with the variants of the intrahepatic bile ducts have a higher incidence of calculus of intrahepatic duct.
