胆道内支架留置术

Biliary Stent Implantation

本文5例恶性肿瘤所致梗阻性黄疸患者,成功施行了胆道内支架留置术,其中1例直接经 T管留置;1例经 T 管内窥镜引导留置;1例 B 超下 PTCD 外引流术后留置;2例直接经 PTCD 后留置。所用支架4例为 Z 型自胀式支架,1例为 Wallstent 支架。支架直径8～10mm,长度6～8cm。留置术后患者黄疸症状逐步减轻至消失,支架未出现再狭窄及移位。最长病例支架留置后存活一年,未出现再狭窄。我们认为,胆道内支架留置术是治疗疗梗阻性黄疸的较理想的方法。

Five patients had of malignant biliary obstruction with implanted biliary stent successfully two stents passed directly,through T tubes,three by PTCD.Four self- expandable Z shaped stents and one Wallstent were used with 8～10mm in diameter and 6～ 8cm in length.The jaundice of all patients alleviated or disappeared gradually after stenting. No restenosis or migration of the stents occurred.The patient that survived longest after the procedure lived one year without restenosis.It was suggested that biliary stent implantation is an ideal choice for treatment of obstructive jaundice.
