Abstract： 目的:总结分析肝门胆管狭窄的病因并探讨各影像学诊断方法在肝门胆管狭窄疾病中的诊断符合率.方法:回顾分析我院及山西医科大学第二医院于1982-2004 82例资料完整的肝门胆管狭窄患者的主要病因以及超声(US)、磁共振胰胆管造影(MRCP)、逆行胰胆管造影(ERCP)、经皮肝穿胆道造影(PTC)等影像诊断结果,分析各项影像技术在肝门胆管狭窄诊断中的适应症和诊断符合率.结果:恶性病变占肝门胆管狭窄病的87.80%,其中大部分由肝门胆管癌引起,占总例数的76.83%,其次胆囊癌占7.32%,结肠癌肝门转移1.22%,肝细胞癌并发癌栓2.44%等.良性病变占12.2%,主要为损伤性胆管、胆管囊肿、硬化性胆管炎以及胆管结石等.US,ERCP,PTC,MRCP对肝门胆管狭窄的诊断准确率分别为84.15%,92.86%,100%,100%.结论:恶性病变是肝门部胆管狭窄病的主要原因,良性病变相对比例较小.在肝门胆管狭窄的诊断中,影像学诊断技术扮演着关键辅助作用的角色,能协助临床迅速获得准确结论.
