摘要
目的探讨影像学检查对肝外胆管癌的诊断价值。方法经病理证实的原发性肝外胆管癌45例进行影像学检查(直接法胆道造影45例,其中经皮肝穿刺胆管造影39例,ER-CP 8例,B 超28例,CT 11例)和回顾性分析。结果原发性肝外胆管癌45例中,病变位于肝外胆管上段31例(68.9%),中段8例(17.8%),下段6例(13.3%)。结论直接法胆道造影表现可分为胆道梗阻、狭窄和息肉样改变。作者认为,经皮肝穿刺胆管造影应作为肝外胆管癌术前诊断的主导方法。将 ERCP,US/CT 合理结合,术前诊断正确率可进一步提高。
AIMS To evaluate the imaging diagnosis in primary extrahepatic bile duct carcinoma. METHODS The imaging features of 45 cases of pathologically con- firmed primary extrahepatic bile duct carcinoma were reviewed. RESULTS The lesion involveded the upper part of the bile duct in 31 cases(68.9%),the middle part in 8(17.8%),the lower part in 6(13.3%). CONCLUSIONS Under direct cholangiography the features could be classified into obstructive,stenotic and polypoid.PTC should be the primary method for diagnosing a primary extrahepatic bile duct carcinoma.The diagnostic accuracy can further be improved when PTC is combined with US/CT and ERCP.
