超高场磁共振3D-MRCP评估胆胰管汇合异常与肝外胆管癌患病率的关系

Ultra-high field magnetic resonance 3D-MRCP for evaluating relationship between pancreaticobiliary duct junction anomaly and prevalence rate of extrahepatic cholangiocarcinoma

目的 评估超高场磁共振3D-胰胆管磁共振成像(MRCP)检查对胰胆管汇合异常与肝外胆管癌患病率关系的应用价值。方法 收集2016年5月至2019年5月230例到该院进行超高场磁共振3D-MRCP检查者的图像资料,采用病例对照研究法,评估超高场磁共振3D-MRCP检查对胆胰管汇合异常与肝外胆管癌患病率关系的应用价值。结果 胰胆管汇合分汇合正常型及汇合异常型。汇合异常型患者肝外胆管癌患病率高于汇合正常型,胰-胆型患者肝外胆管癌患病率高于胆-胰型,差异均有统计学意义(P<0.05)。结论 肝外胆管癌的发生与胆胰管汇合异常关系密切,超高场磁共振3D-MRCP评估胰胆管汇合异常与肝外胆管癌患病率的关系具有较高的应用价值。

Objective To evaluate the application value of ultra-high field magnetic resonance 3D-MRCP examination in the relation between the pancreaticobiliary duct junction anomaly and the incidence of junction abnormal type.Methods The imaging data in 230 cases of ultra-high field magnetic resonance 3D-MRCP in this hospital from May 2016 to May 2019 were collected.The case-control study method was used to evaluate the application value of ultra-high field magnetic resonance 3D-MRCP in the relationship between pancreaticobiliary duct junction anomaly and the prevalence of extrahepatic cholangiocarcinoma.Results The pancreaticobiliary duct junction was divided into the normal junction type and abnormal junction type.The prevalence rate of extrahepatic cholangiocarcinoma in the patients with junction abnormal type was higher than that in the patients with junction normal type.The prevalence rate of extrahepatic cholangiocarcinoma in the patients with junction abnormal type was higher than that in the patients with junction normal type;the prevalence rate of extrahepatic cholangiocarcinoma in the patients with pancreaticobiliary type was higher that in the patients with biliary-pancreatic type(P<0.05).Conclusion The occurrence of extrahepatic cholangiocarcinoma is closely related to the abnormal junction of biliopancreatic duct.The ultra-high field magnetic resonance 3D-MRCP for evaluating the relationship between the pancreaticobiliary duct junction anomaly and the prevalence rate of extrahepatic cholangiocarcinoma has the higher application value.
