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
To summarize the long-term efficacy of endoscopic placement of expandable biliary metal stent (EMBE), the data of 76 patients with malignant biliary obstruction treated with EMBE were retrospectively reviewed and compared with the efficacy of 53 cases of common biliary stents placed in the same period. The former resulted in a successful operation rate of 93.8%, the incidence of complications related to operation was 6.6%, the elimination rate of jaundice was 87.0%, and the mean patency of metallic stents was 310 days, which was significantly higher than that of plastic stents for 85 days. (P<0.01), the average survival time of patients was 210 days. Stent occlusion occurred in 16 (34.8%) of follow-up patients, with an average time of 185.5 days. The results showed that the average patency of the expandable metal biliary stent was significantly better than that of the ordinary plastic stent, and the extrahepatic bile duct obstruction caused by malignant tumors can be effectively and permanently eliminated. In order to improve the efficacy of EMBE, strict indications must be obtained.
