目的:探讨金属内支架对38例各种原因引起的食管狭窄及合并食管瘘的治疗效果.材料与方法:支架为记忆合金丝编织网格型,低碳医用不锈钢丝编织“Z”型及被覆支架.在X线电视监视下使用支架输送系统放置食管内支架治疗食管狭窄29例,9例合并食管瘘.结果:明显缓解了患者进食困难症状,尤其是被覆支架对治疗各种食管瘘有特效.随访时间最长3年,最短1个月,平均3.6个月.患者无不良反应.结论:采用食管支架治疗各种食管狭窄及食管瘘是安全、有效的方法.“,”Objective: To evaluate the metallic stent in treating of esophageal stricture and complicated fistula due to various causes.Materials and Methods:Three types of esophageal stent were used: NiTi wire meshlike stent, stainless steel “Z” stent and covered stainless sleel stent. By delivery system stent placement was performed in 38 cases with esophageal stricture, of which 9 cases complicated fistula.Results:Dysphagia was alleviated markedly in all patients. The covered stent was particularly effective for esophageal fistula. Followingup time varied from 1 month to 3 years with an average of 3.6 months. No any adverse effect was noted in all patients.Conclusion: Esophageal stent is an safe and effective therapy for the treatment of various esophageal strictures and fistulae.
