摘要 为总结经内镜放置可膨式金属胆道支架(EMBE)的中远期疗效，回顾了76例恶性胆管梗阻接受EMBE治疗患者的资料，并与同期53例次放置普通塑料支架的疗效进行对比。结果前者操作成功率93.8%，与操作有关的并发症发生率6.6%，黄疸消除率为87.0%，金属支架的平均通畅期为310天，明显高于塑料支架的85天(P<0.01)，患者平均存活期为210天。随访患者中有16例(34.8%)发生支架阻塞，平均发生时间185.5天。结果表明可膨式金属胆道支架的平均通畅性能显著优于普通塑料支架，可持久有效解除恶性肿瘤所致的肝外胆管梗阻，为提高EMBE的疗效必须严格掌握适应证。
MEDIUM AND LONG TERM RESULTS OF SELF-EXPANDING METAL STENT FOR MALIGNANTBILE DUCT OBSTRUCTION Hu Bing,Zhou Daiyun,Gong Biao,etal.Orient Hepatobiliary Surgery Hospital,Second Military Medical University,Shanghai200438
Abstract The records of patients with malignant biliaryobstruction treatd with endoscopic (self-expanding)metal biliary endoprothesis (EMBE,n=76) versus conventional polyethylene stent (n=53) were compared to evaluate the mediumand long term effects. Results disclosed that with the former successful implantation wasachieved in 93.8%;complication due to procedure limited to 6.6%;jaundice diminished in87.0%;stent patency kept for 310 days in average (versus 85 days for the latter,P<0.01)；patientsurvived for an average of 210 days;stent occlusion ensued in 34.8% (n=16) on the 185.5days. Conclusively the self-expanding metal stent maintained its patency better and longerthan that of polyethylene to palliate biliary obstruction. The mastery of indication seemsmost essential.
