Endosonography was performed preoperatively in 46 patients with carcinoma of the common hepatic duct and its bifurcation. The results of endosonography were correlated with findings during surgery and pathological examination of the resected specimen and classified according to the new (1987) TNM classification. Overall accuracy in assessing the depth of tumor infiltration was 86.0%. Endosonography was accurate in predicting the presence of lymph nodes but not accurate in defining non-metastatic changes of lymph nodes. Staging of distant metastases was not accurate due to the low penetration depth of ultrasound.
对46例肝总管及其分叉处癌患者进行了术前超声内镜检查。将超声内镜检查结果与手术中的发现以及切除标本的病理检查结果进行关联，并根据新的（1987年）TNM分类进行分类。评估肿瘤浸润深度的总体准确率为86.0%。超声内镜检查在预测淋巴结的存在方面准确，但在确定淋巴结的非转移变化方面不准确。由于超声的穿透深度较低，远处转移的分期不准确。
