A study of percutaneous transhepatic cholangiograms in 94 consecutive patients revealed that success is largely determined by the number of passes attempted. Two of 43 patients with dilated intrahepatic ducts had unsuccessful cholangiograms, but in these patients only two and three passes were attempted. In the remaining 41 patients fewer than seven passes were required. In patients with nondilated ducts, the success rate bears an almost linear relationship to the number of attempted passes beyond the fourth pass. Since patient tolerance often limits the number of passes, careful technique is important; one such technique is described. In the cholangiogram failures with nondilated ducts, subsequent liver biopsy had a high diagnostic yield.
一项对94例连续患者进行的经皮肝穿刺胆管造影研究显示，成功率很大程度上取决于尝试穿刺的次数。43例肝内胆管扩张患者中有2例胆管造影未成功，但在这些患者中仅尝试了2次和3次穿刺。其余41例患者所需穿刺次数少于7次。在肝内胆管未扩张的患者中，成功率与第4次穿刺后尝试穿刺的次数几乎呈线性关系。由于患者的耐受性常常限制穿刺次数，因此操作技术要精细，这一点很重要；本文描述了一种这样的技术。在肝内胆管未扩张的胆管造影失败病例中，随后进行的肝活检具有较高的诊断率。
