对20例胆管癌超声诊断的结果进行分析，梗阻病因诊断符合率为90％（18／20），误诊的2例中，1例是总胆管下段癌，因肿瘤后方有弱声影误诊为总胆管结石；另三例是肝门部狭窄型胆管癌误诊为硬化性胆管炎。梗阻部位判断正确率为80％，作者讨论了胆囊大小的临床意义及狭窄型胆管癌的鉴别诊断。认为胆囊状态不能作为判定梗阻部位及胆囊受侵的唯一依据。并认为彩色多谱勒技术对梗阻部位的判断非常有意义。对确定梗阻的病因，由于倒数较少，尚有待进一步研究。
The results of ultrasound diagnosis of 20 cases of cholangiocarcinoma were analyzed. The coincidence rate of diagnosis of obstruction etiology was 90% (18/20). Of the 2 cases misdiagnosed, 1 was of the lower common bile duct carcinoma. Bile duct stones; the other three cases were misdiagnosed as sclerosing cholangitis. The correct rate of obstruction was 80%. The authors discussed the clinical significance of gallbladder size and differential diagnosis of stenotic cholangiocarcinoma. The gallbladder state cannot be used as the sole basis for determining the location of the obstruction and gallbladder invasion. And that color Doppler technology is very meaningful to determine the location of obstruction. To determine the cause of obstruction, because the countdown is less, it needs further study.
