目的探讨国产食管金属内支架治疗食管癌性狭窄、食管—气管瘘及食管—纵隔瘘临床应用价值。方法先用导丝通过狭窄段，经球囊扩张，置入带膜食管金属内支架。结果48例食管狭窄者内支架置入后吞咽困难完全消除的7例（14．6％），41例（85．4％）明显缓解。6例食管—气管瘘口封闭。结论国产食管金属内支架置入是治疗食管恶性狭窄安全可靠的方法，术后应继续进行抗癌治疗。
Objective To investigate the clinical application value of homemade esophageal metal stent in the treatment of esophageal cancer stenosis, esophageal fistula and esophagus-mediastinum. Methods The guide wire was used to pass through the stenosis section and was balloon-expanded to insert the membrane-supported esophageal metal stent. Results Among the 48 patients with esophageal stenosis, 7 (14.6%) patients with dysphagia were completely eliminated after stenting, and 41 patients (85.4%) had obvious relief. Six cases of esophageal-tracheal fistula were closed. Conclusion Domestic esophageal metal stent placement is a safe and reliable method for the treatment of malignant esophageal stenosis. Anticancer therapy should be continued after surgery.
