To evaluate the feasibility of percutaneous ultrasound cholangiography (PUSC) with a microbubble contrast agent in assessing obstructive bile duct diseases.
PUSC and percutaneous transhepatic cholangiography (PTC) were performed in 58 patients with obstructive jaundice undergoing ultrasound-guided percutaneous transhepatic cholangial drainage (PTCD). The PUSC findings were compared with PTC using the Chi-squared test
The accuracy of PUSC in determining the level of hilar obstruction and extrahepatic obstruction was 100% (26/26) and 93.3% (30/32), while the accuracy of PTC was 100% for both (P = 1.000, P = 0.492, respectively). The accuracy of PUSC in determining the cause of hilar obstruction and extrahepatic obstruction was 92.3% (24/26) and 93.8% (30/32), respectively, while the accuracy of PTC was 84.6% (22/26) (P = 0.675) and 75% (24/34) (P = 0.039), respectively.
PUSC is comparable to PTC in depicting the anatomy of the dilated bile duct tree and determining the level of obstruction for patients with obstructive jaundice, hence it expands the capacity of ultrasound in evaluating obstructive bile duct disease and simplifies the procedure of assessing obstructive jaundice. Key Points • Percutaneous ultrasound-guided cholangiography with microbubbles offers a new form of cholangiography • PUSC compares well with PTC in evaluating the dilated biliary tract. • Radiation is avoided and overall costs may be lower.
评估微泡对比剂经皮超声胆管造影（PUSC）在评估梗阻性胆管疾病中的可行性。
对 58 例接受超声引导经皮经肝胆管引流术（PTCD）的梗阻性黄疸患者进行 PUSC 和经皮经肝胆管造影术（PTC）。采用卡方检验比较 PUSC 与 PTC 的结果。
PUSC 确定肝门部梗阻和肝外胆管梗阻水平的准确率为 100%（26/26）和 93.3%（30/32），而 PTC 的准确率均为 100%（P=1.000，P=0.492）。PUSC 确定肝门部梗阻和肝外胆管梗阻原因的准确率分别为 92.3%（24/26）和 93.8%（30/32），而 PTC 的准确率分别为 84.6%（22/26）（P=0.675）和 75%（24/34）（P=0.039）。
对于梗阻性黄疸患者，PUSC 在描绘扩张胆管树的解剖结构和确定梗阻水平方面与 PTC 相当，从而扩展了超声评估梗阻性胆管疾病的能力并简化了评估梗阻性黄疸的程序。关键要点：• 经皮超声引导胆管造影联合微泡提供了一种新的胆管造影形式。• PUSC 在评估扩张胆管方面与 PTC 相当。• 避免了辐射，总费用可能更低。
