摘　　要：目的：通过回顾经超声诊断并经手术、病理证实的５２例肝外胆管癌，分析总结其声像图特征，并讨论与胆管扩张的相关性。方法：应用ＡＬＯＫａＳＳＤ—２５６及ＴｏｓｈｉｂａＳＡＬ—５５Ａ、Ａｐｏｇｅｅ—８００超声诊断仪，探头频率３５ＭＨｚ，患者空腹８～１２ｈ，取仰卧位、左侧卧位，对肝、胆系统进行连续的纵、横、斜切扫查，注意胆管的宽度及走行，胆管有无异常肿块，管壁有无增厚，管腔有无狭窄等征象。结果：本组５２例肝外胆管癌，上段胆管癌１６例（３０７７％）；中段胆管癌８例（１５３８％）；下段胆管癌２８例（５３８５％）；Ｂ超对其部位及性质诊断完全准确者４０例，诊断符合率为７６９２％。结论：１）肝外胆管癌有其典型的声像图特征，Ｂ超对其部位及性质的确定有重要价值；２）胆管扩张的程度与胆管癌发生的部位有直接的关系。Purposes:Viewing and summarizing 52 cases of the carcinoma of extrahepatic bile duct,which had been initially diagnosed with ultrasound and later surgically and pathologically confirmed,this article analyzes the ultrasound characteristics of the disease and discusses the relationship between bile duct expansion and carcinoma of extrahepatic bile duct.Methods:with Aloka SSD-256,Toshiba SAL-55A and Apogee-800 ultrasound monitors,all the patients were diagnosed.Results:Among the 52 cases with carcinoma of extrahepatic bile duct,16 cases(30.77%) were found at hilar sites of bile duct;8 cases(15.38%) at middle sites;28 cases (53.85%) at distant sites.With 40 cases being diagnosed correctly both in terms of position and pathological nature,the rate of accuracy is 76.92% (40/52).Conclusions:1) Ultrasound has inportant values for determining the position and nature of Carcinoma of extrahepatic bile duct.2) The degree of bile duct expansion has direct relation to position of bile duct carcinoma.
