经皮胆管超声造影与X线造影对肝门部胆管癌进行分型的比较研究

目的 探讨经皮胆管超声造影在肝门部胆管痛Bismuth分型中的准确性和有用性.方法 纳入30例经手术确诊为肝门部胆管癌的患者进行前瞻性研究.所有患者分别接受了二维超声、声诺维经皮超声胆道造影(PUSC)和泛影葡胺经皮经肝X线胆道造影(PTC),并经手术或临床确诊为肝门部胆管癌.以手术结果为金标准,比较三者对肝门部胆管癌进行Bismuth分型的准确性.结果 普通超声分型的准确率为23.3%(7/30),PUSC和PTC分型的准确率均为73.3%(22/30).普通超声分型准确率与PUSC及PTC之间差异具有统计学意义.结论 超声胆管造影提高了超声评估肝门部胆管癌的能力,对肝门部胆管癌进Bismuth分型的效能与PTC相近.

Classifying of hilar cholangiocarcinoma: a comparison study between percutaneous ultrasonic cholangiography and percutaneous transhepatic cholangiography

Objective To evaluate the accuracy and utility of percutaneous ultrasonic cholangiography in Bismuth staging of hilar cholangiocarcinoma. Methods Thirty patients who underwent surgery and obtained pathologic diagnosis of hilar cholangiocarcincoma were perspectively ruled in this study. All patients with hilar obstruction underwent baseline ultrasound (BUS), percutaneous ultrasonic cholangiography (PUSC) and percutaneous transhepatic cholangiography(PTC) respectively. Taking operative findings as reference standard,the accuracy of the three imaging modalities in staging of hilar cholangiocarcinoma was compared. Results Among 30 patients, the accuracy of classification among BUS, PUSC and PTC was 23.3 % (7/30), 73.3 % ( 22/30 ), 73.3 % (22/30), respectively. There was statistically significant difference between BUS and PUSC, but the difference between PUSC and PTC was not statistically significant.Conclusions As a new technique for cholangiography, PUSC expands the application of ultrasound in evaluating hilar cholangiocarcinoma and is comparable to PTC in classifying hilar cholangiocarcinoma by Bismuth classification.
