摘　　要：为了进一步探讨应用超声诊断胆管癌对周围组织脏器侵及的可行性，我们对中上段胆管癌肝浸润（５５例）、胆囊浸润（５６例）进行了回顾性分析。确定了肝浸润的四个程度：未受侵Ｌｉ（一），可疑受侵Ｌｉ（±），受侵Ｌｉ（＋），明显受侵Ｌｉ（）；胆囊受侵亦分为四个程度；未受侵Ｇｉ（一），可疑受侵Ｇｉ（±），受侵Ｇｉ（＋），明显受侵Ｇｉ（）。根据此标准，并与手术及病理结果对照，超声诊断总的正确率分别为７４％、７７％，其中Ｌｉ（）及Ｇｉ（）均得到正确诊断；同时讨论了胆囊大小的临床意义，认为胆囊大小不能作为判断梗阻部位及胆囊受侵的唯一依据；并分析了超声诊断胆囊受侵假阳性较高的主要原因。总之，超声对于判断胆管癌侵及周围组织脏器有价值。In order to inquire into diagnostic feasibility of cholangiocarcinoma infiltraing into adjacent organs with ultrasound.55 cases of liver parenchyma infiltration and gallball infiltration were retrospectively studied in this paper.Four different degrees were determined:non infiltration(-),suspicious infiltration(±),infiltration(+),obvious infiltration().According to this standard,ultrasounic accurate rate were 74%,77%,respectively,compared with operative and pathological findings,and all cases with Li()and Gi()were judged correctly.Gallball size doesnt serve as the only basis in predicting the obstruction level and gallball infiltraion,and main causes for high false postives were discussed.In conclusion,ultrasound is valuable in predicting tumor extension
