Cholangiography used with oral or intravenous contrast agents has gained wide acceptance as the most objective preoperative diagnostic technique for choledocholithiasis. However, an indirect contrasting technique has been found quite unfit in patients with severe bilirubinemia. Despite this, the authors employed indirect contrasting of the bile ducts in 104 patients with severe bilirubinemia in combination with computed tomographic cholangiography. Contrasting took place in 90 (86.5%) patients. In complete obstruction of the choledochus (10 patients), intraductal hypertension prevents the contrast agent and bile from entering the hepatic ducts and the contrast agent is excreted by the kidneys. Thus, the use of the latest equipment and computers allows one to detect minor biliary contrast concentrations during indirect contrasting of the biliary tract in severe bilirubinemia.
使用口服或静脉造影剂的胆管造影术作为胆总管结石最客观的术前诊断技术已被广泛接受。然而，已发现间接造影技术在严重胆红素血症患者中非常不适用。尽管如此，作者对104例严重胆红素血症患者采用间接胆管造影术并结合计算机断层胆管造影术。90例（86.5%）患者进行了造影。在胆总管完全梗阻的患者（10例）中，导管内高压阻止造影剂和胆汁进入肝内胆管，造影剂由肾脏排出。因此，使用最新的设备和计算机能够在严重胆红素血症患者进行胆道间接造影时检测到微量的胆道造影剂浓度。
