胆道支架介入治疗恶性胆道梗阻136例临床分析

目的探讨胆道支架(金属支架、塑料支架)介入治疗恶性胆道梗阻的应用价值。方法2005年8月～2008年5月,对136例不宜行手术治疗的恶性胆道梗阻患者,通过内镜途径或经皮经肝途径行胆道支架置入术。结果内镜成功128例,不成功的8例行经皮经肝穿刺。放置金属支架71例,塑料支架65例。放置胆道内支架1周后,血清总胆红素、ALT、AST均明显下降(P0.01),临床症状显著改善。71例放置胆道金属支架者中,11例术后2个月内支架阻塞,再次放置塑料支架后引流通畅;余60例支架通畅时间270～286d,平均275d。65例放置塑料内支架者中,9例术后1～4周支架移位和梗阻,重新置入塑料支架;余56例支架通畅时间110～128d,平均118d。经皮经肝途径术后发生胆汁性腹膜炎1例,经保守治疗治愈。其余病例无严重并发症。随访生存时间1.5～28个月,存活3个月以上者92例。结论胆道支架介入治疗恶性胆道梗阻疗效确切,适用于不宜手术者,对于解除晚期恶性胆道梗阻性黄疸、缓解症状、提高患者生存质量具有满意效果。估计生存期3个月者,宜选择金属支架;估计生存期3个月或经济条件不充许者,可选用塑料支架。

Biliary Stenting for Malignant Biliary Obstruction:Analysis of 136 Cases

Objective To assess the safety and effectiveness of biliary stents in treating patients with malignant biliary obstruction(MBO).Methods From August 2005 to May 2008,136 patients with MBO,who showed contraindications for surgical treatment,were treated by biliary stenting through endoscopic or percutaneous transhepatic route.Results Biliary stenting was completed by using endoscopy in 128 patients,the other eight patients received percutaneous transhepatic cholangiography(PTC)because of failure in endoscopy....
