目的:探讨自膨式食管金属加膜支架治疗恶性食管狭窄和气管食管瘘的疗效和并发症。方法:2004年1月至2009年6月对63例恶性食管狭窄和气管食管瘘患者实施食管支架置入,男45例,女28例;年龄45～81岁,平均69.3岁。支架为MTN型形状记忆钛镍合金食管加膜支架(南京微创医学科技有限公司生产),支架植入均在DSA监视下操作完成。结果:63例均一次性放置成功,即刻口服造影通过顺利剂。结论:自膨式食管金属加膜支架是治疗恶性食管狭窄和气管食管瘘的有效方法。
Objective: To investigate the efficacy and complications of self-expanding esophageal metal stent in treatment of malignant esophageal stenosis and tracheal esophageal fistula. Methods: From January 2004 to June 2009, 63 patients with malignant esophageal stenosis and tracheoesophageal fistula were treated with esophageal stenting. There were 45 males and 28 females, aged 45-81 years, with an average of 69.3 years. The stent is a MTN-shaped titanium-nickel alloy esophageal stent graft (produced by Nanjing Minimally Invasive Medical Technology Co., Ltd.). Stent implantation is performed under the supervision of the DSA. Results: All the 63 cases were successfully placed in one time. Immediate oral contrast was passed through smoothing agents. Conclusion: Self-expanding esophageal metal stent is an effective method to treat malignant esophageal stenosis and tracheal esophageal fistula.
