MRCP诊断胆囊管低位汇入的价值(附30例分析)

Value of MR cholangiopancreatography in diagnosis of low confluence of cystic duct(report of 30 cases)

目的探讨磁共振胰胆管成像（MRCP）诊断胆囊管低位汇入的价值。方法收集2012年10月～2014年3月期间行MRCP检查的271例患者的图像进行回顾性分析,测量肝总管的长度和胆总管的长度,二者的比值大于1时诊断胆囊管低位汇入,分析低位胆囊管的汇合部位及其有无胆囊炎、胆囊结石。结果 271例患者中胆囊管低位汇入者30例（11.1%）,其中胆囊管低位汇入肝外胆管右侧壁者5例（17.7.0%）,后壁者9例（30.0%）,左侧壁者16例（53.3%）。结论 MRCP检查有助于发现和诊断胆囊管低位及其并发症,具有重要的临床应用价值。

Objective To evaluate the value of magnetic resonance cholangiopancreatography（MRCP）in diagnosis of low confluence of cystic duct.Methods We collected the images of 271 cases who were received MRCP examination during October 2012 to March 2014.The data were retrospectively analyzed.We measured the length of the common hepatic duct and the common bile duct（CBD）.When the ratio of the two is greater than 1,it is defined as low confluence of cystic duct.Then,we determined the confluence site of low confluence of cystic duct,and whether cholecystitis or gallbladder stones was present or not.Results 30 cases of low confluence of cystic duct were found in the 271patients（11.1%）.Among those,there were 5cases importing to the right lateral wall of the extrahepatic bile duct（16.7%）,9cases to the posterior wall（30.0%）,and 16 cases to the left lateral wall（53.3%）.Conclusion MRCP is helpful to discover and diagnose low confluence of cystic duct and its complications,which is of significant value clinically.
