目的：探讨国产镍钛合金支架治疗食管良恶性狭窄的疗效。方法：２４例中食管化学烧伤后狭窄２例，贲门失弛缓症５例，食管—胃吻合口狭窄１０例，食管贲门癌７例。全部支架置入术均经口腔在Ｘ线监视下进行。结果：所有病人的支架留置均获成功。支架置入后患者吞咽困难得以缓解，所有病人的摄食能力都有不同程度的改善，总有效率达１００％。结论：国产支架置入术治疗食管良恶性狭窄是一种简单、安全和有效的方法，远期效果尚需进一步观察。
Objective: To investigate the curative effect of domestic nitinol stent in the treatment of benign and malignant esophageal stenosis. Methods: Twenty-four patients were diagnosed as esophageal and gastric cardia cancer by stenosis in 2 cases, achalasia in 5 cases, esophageal-gastric anastomotic stenosis in 10 cases and esophageal and cardiac cancer in 7 cases. All stents were implanted through the oral cavity under X-ray monitoring. Results: All patients were successfully placed indwelling stent. Patients with dysphagia after stent placement were relieved and all patients had varying degrees of improvement in feeding capacity with a total effective rate of 100%. Conclusion: Domestic stent implantation for the treatment of benign and malignant esophageal strictures is a simple, safe and effective method, the long-term results need to be further observed.
