Two hundred one biliary endoprostheses were inserted transhepatically with a two-step procedure in 162 patients. Teflon endoprostheses were inserted in the initial 95 patients and polyethylene in seven others. Because in vitro experiments and clinical experience have revealed a lower incrustation rate with Percuflex and polyurethane, endoprostheses made of these materials were used in the last 60 patients. The mortality rate directly related to the procedure was 3.7%, and postprocedural complications occurred in 9% of the patients. Delayed complications included cholangitis in 20%, obstruction in 6%, and dislocation in 3% of the cases. The mean survival time of all 162 patients was 20 weeks. It is concluded that endoprostheses offer effective palliative treatment of obstructive jaundice caused by malignancy.
采用两步法经皮肝穿刺为162例患者植入了201个胆道内支架。最初的95例患者植入了聚四氟乙烯内支架，另外7例植入了聚乙烯内支架。由于体外实验和临床经验表明，Percuflex和聚氨酯的结壳率较低，因此后60例患者使用了由这些材料制成的内支架。与该手术直接相关的死亡率为3.7%，9%的患者出现术后并发症。延迟并发症包括20%的患者发生胆管炎，6%的患者发生梗阻，3%的患者发生移位。162例患者的平均生存时间为20周。结论是内支架为恶性肿瘤引起的梗阻性黄疸提供了有效的姑息治疗。
