Sixtyfour jaundiced patients were randomly allocated to have fine needle PTC performed with or without prior ultrasonographical localization of the porta hepatis. The general success rate was 97% and complications occurred in two patients (3%). Ultrasonography prior to PTC did not significantly reduce the number of needle passes in the liver parenchyma, the failure rate or the number of complications. Ultrasonic scanning, however, should precede PTC to disclose patients with obstructive jaundice and reveal hepatic and perihepatic abnormalities.
64例黄疸患者被随机分为两组，一组在肝门部预先进行超声定位后行细针经皮肝穿刺胆管造影（PTC），另一组则不进行超声定位直接行PTC。总体成功率为97%，2例患者（3%）出现并发症。PTC术前超声检查并未显著减少肝实质内的穿刺针数、失败率或并发症数量。然而，在进行PTC之前应先进行超声扫描，以发现梗阻性黄疸患者，并揭示肝脏及肝周异常情况。
