摘要
目的探讨肝门部胆管癌所致的胆道梗阻和原发性肝癌或转移性肝癌的胆道癌栓导致肝门部胆道梗阻的不同影象学特点。方法在病理确诊为肝门部胆管癌和原发性肝癌或转移性肝癌所致的胆道癌栓导致胆道梗阻的70例患者中进行CT片MRCP片及ERCP片的影像学特点分析。结果男性45例,女性25例,肝门部胆管癌患者占65.7%,胆管癌栓患者占34.3%。在肝门部胆管癌致胆道梗阻中,CT检查诊断符合率为85%,MRCP为95%,ERCP为90.9%。在胆管癌栓致胆道梗阻中,CT检查诊断符合率为87.5%,MRCP为96%,ERCP为92%。结论从影像学诊断来讲,CT、MRCP和ERCP都具有重要的临床应用价值,MRCP和ERCP对两者鉴别最有价值。ERCP不但可以明确诊断,而且可以解除胆道梗阻。
Objective Study the different imaging features of obstruction of biliary tract caused by hepatic portal cholangiocarcinoma and cancer embolism of bile ducts resulted of primary or metastatic liver cancer.Methods Analyze CT,MRCP and ERCP images of obstruction of biliary tract in 70 patients retrospectively,which were proven pathologically as hepatic portal cholangiocarcinoma cancer and embolism or biliary calculi resulted in liver cancer.Results In these 70 patients,45 male and 25 female, 46 cases（65.7%） were hepatic portal cholangiocarcinoma and 24 cases（34.3%） were cancer embolism.In the obstruction of biliary tract caused by hepatic portal cholangiocarcinoma,the diagnostic confidence of CT scan was 85%,MRCP was 90%and ERCP was 90.9%.In the obstruction of biliary tract caused by cancer embolism,the diagnostic confidence of CT was 87.5%,MRCP was 96%and ERCP was 92%. Conclusions For imaging diagnosis,it has important clinical application values for CT imaging,MRCP or ERCP respectively.For differential diagnosis,MRCP and ERCP are more valuable.ERCP not only can make final diagnosis for these two diseases,but also can remove the obstruction matter directly.
