Abstract:
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.
