We investigated the extent to which BDca can be visualized and diagnosed via a percutaneous fistula using IDUS. IDUS was performed in 42 cases, including 15 of normal bile ducts; 12 of choledocholithiasis, and 15 of BDca. The depth of invasion of the BDca was diagnosed with a 93% accuracy rate by visualizing the EP or MA or both. The infiltration of BDca into the surrounding organs was clearly visualized and diagnosed with an accuracy of 100% in the RHA, 93% in the PV, and 93% in the pancreas. These accuracy rates were higher than those obtained by computed tomography or angiography. We believe, therefore, that IDUS should be further studied as a diagnostic modality for staging malignancy in the biliary field.
我们研究了通过经皮瘘管使用内镜超声（IDUS）可视化和诊断胆管癌（BDca）的程度。对42例患者进行了IDUS检查，其中包括15例正常胆管患者、12例胆总管结石患者和15例胆管癌患者。通过可视化包膜外血管（EP）或门脉周围转移（MA）或两者来诊断胆管癌的浸润深度，准确率为93%。胆管癌向周围器官的浸润在肝右动脉（RHA）中可视化并诊断的准确率为100%，在门静脉（PV）中为93%，在胰腺中为93%。这些准确率高于通过计算机断层扫描或血管造影获得的准确率。因此，我们认为，内镜超声应作为胆道领域恶性肿瘤分期的诊断方法进行进一步研究。
