超声引导下经皮经肝穿刺胆管置管引流的技术应用

目的；探讨超声引导下经皮经肝穿刺胆管置管引流术的技术应用及临床价值。方法：对1999年5月-2005年3月187例（237例次）超声引导下经皮经肝穿刺胆管置管引流术进行回顾性总结。结果：1次穿刺胆管成功率高达96．2％，2次穿刺胆管成功率100％；穿刺并首次置管成功率90．7％，再次置管成功率99．6％；仅1例经3次置管成功。并发症主要为胆汁带血，发生率7．6％。结论：超声引导下经皮经肝穿刺胆管准确安全，置管简便有效，作为多种晚期肿瘤的姑息性治疗方法厦梗阻性黄疸伴严重感染的一项有效治疗措施，常为临床首选。

Technical Application of Ultrasound-guided Percutaneous Transhepatic Biliary Drainage

Objective:To discuss the technical application and clinical value of ultrasound-guided percutaneous transhepatic bili- ary drainage(PTBD).Methods:Restrospective analysis of 237 times PTBD in 187 cases were done for the operating methods, successive rate,influence factors and complications of this procedure.Results:The successive rate of single puncture of bile duct was up to 96.2%,that of twice puncture was 100%.The successive rate of single drainage was 90.7%,and that of twice drainage was 99.6%.Only one case needed the third-times drainage and was succeeded.The complications were mainly hemobilia(7.6%).Conclusion:Ultrasound-guided PTBD is a safe,less invasive and simple procedure for treating inoperable biliary obstructions.Meanwhile,it provides more chances for other treatments on late-stage oncology patients or obstructive jaundice with severe infection.
