肝门区胆管癌的MRI诊断与术前评估价值

MRI findings and preoperative evaluation of hepatic hilum cholangiocarcinoma

目的:研究肝门区胆管癌(Hepatic hilum cholangiocarcinoma,HHC)的磁共振成像(Magnetic resonance imaging,MRI)表现,探讨MRI对该病的诊断和术前评估价值。方法:回顾性分析经病理证实的21例肝门区胆管癌MRI表现,磁共振胆胰管成像(Magnetic resonance cholangio pancreatography,MRCP)分型与手术所见的临床分型对照,MRI术前不可切除性评估与手术结果比较。结果:21例肝门区胆管癌均显示肝内胆管不同程度扩张,胆管中断,其中可见肝门区肿块16例,MRI增强以延迟强化为主。MRCP分型与手术分型无显著性差异(P>0.05)。MRI对肝门区胆管癌能否被切除的准确率为81%(17/21)。结论:MRI是诊断和术前评价肝门区胆管癌的可行性方法。

Objective：To study MRI findings of hepatic hilum cholangiocarcinoma and evaluate its diagnostic value and preoperative evaluation value.Methods：MRI findings in 21 patients of hepatic hilum cholangiocarcinoma proved pathologically were retrospectively analyzed;MRCP classification and clinical classification were compared;preoperative evaluations and operative results were compared.Results：All patients were found to have intrahepatic biliary duct dilation and discontinuity of hilar ducts,with soft tissue mass at porta hepatis in 16 cases;delayed enhancement was found.The classification is of no significant difference between MRCP and operation findings（P〉0.05）.The accuracy of preoperative evaluation in all patients of hepatic hilum cholangiocarcinoma was 81%（17/21）.Conclusion：MRI is a valid method in the diagnosis of hilar cholangiocarcinoma and its preoperative evaluation.
