经PTC或ERC两种途径放置胆道支架治疗恶性胆管梗阻对比分析

目的比较经PTC或ERC两种途径放置胆道支架治疗恶性胆管梗阻的疗效。方法 PTC途径:在超声引导下选择胆管走行与胆总管夹角较大、扩张的左右肝内胆管,穿刺置管引流,1周后再置入支架,共68例(其中有2例系ERC途径失败者)。ERC途径:在十二指肠镜下逆行插入引流管于胆总管内,经造影显示梗阻部位,其引导丝通过梗阻部位,然后沿引导丝置入支架,共53例。结果 经PTC或ERC途径放置支架成功率分别为100%(68/68)和96.2%(51/53),2组均未发生出血及漏胆并发症。全部患者获随访1～18个月(平均12.4个月),结果PTC组和ERC组放置支架后6个月内死亡者分别为7和5例,18个月仍存活者分别为17和9例。结论对失去手术机会或不能耐受手术的恶性胆管梗阻患者采取支架置入是有效解除梗阻、延长生存时间和提高生存质量的最佳方法。位于胆总管下端和壶腹部的梗阻首选ERC途径放置支架;位于肝门部及以上的梗阻应以PTC途径放置支架为宜。

The Compare and Analysis of Biliary Tract Stent Placing for Malignant Obstruction of Biliary Tract by Percutaneous Transhepatic Cholangiography or Endoscopic Retrograde Cholangiography

Objective To compare the therapeutic efficacy of biliary tract stent placing for malignant obstruction of biliary tract by percutaneous transhepatic cholangiography(PTC) or endoscopic retrograde cholangiography(ERC).Methods PTC approach: choosing the expansion intrahepatic bile duct which had a large angle traveling with common bile duct at the ultrasound-guided,we performed bile duct puncture and inserted the drainage pipe into it,then stent was placed with 68 cases (2 cases among the total were failure of...
