食管带膜支架临床应用的初步探讨

Evaluation of membrane-covered self-expanding stent in clinical use

目的：探讨食管带膜支架治疗晚期食管癌、食管癌术后吻合口狭窄及食管－气管瘘病人的效果。方法：采用内镜法、直接法或手术法为晚期食管癌、吻合口狭窄、复发及食管－气管瘘病人２１例置入２２个支架。结果：除吻合狭窄５０％（２／４）移位外，疗效满意，明显改善了病人生活质量。结论：食管带膜支架置入术操作简单有效，安全可靠，特别适用于晚期食管癌的狭窄和食管－气管瘘的病人。

Objective: To evaluate therapeutic effect of membrane-covered self-expanding metallic stent for advanced esophageal carcinoma, anastomotic stricture and esophagotracheal fistula. Methods: Twenty-two membrane-covered self expandable stents were implanted in patients with malignant stricture, anastomotic stricture and esophagotracheal fistula. The implantation of the stents was performed under endoscopy and oral implantation or surgery. Results: The degree of dysphagia was reduced. The quality of life for the patients is obviously improved, except 50% stent tube migration for anastomotic stricture (2/4). Conclusion: Membrane-covered self-expanding metallic stent is effective, safe and easy to insert, especially, for the stricture of the advanced esophageal carcinoma and the esophagotracheal fistula patients.
