作者总结了５例上消化道良恶性狭窄的食管自扩金属支架治疗经验。介绍了严重狭窄（＜０２ｃｍ）病例的插入导丝方法和食管自扩金属支架的应用。狭窄处直径由０１～０３ｃｍ扩张至１８～２１ｃｍ。吞咽困难由３～４级改善为０～１级。作者认为：对于经多次球囊导管扩张效果不佳的吻合口狭窄，应用食管自扩金属支架治疗，可取得立竿见影的疗效。对于恶性狭窄，应用食管自扩金属支架治疗的同时，再配合放、化疗才能提高总体疗效。
The authors summarized 5 cases of benign and malignant upper gastrointestinal esophageal self-expanding metal stent treatment experience. The application of the guide wire insertion method and esophageal self-expanding metal stent in severe stenosis (<0.2cm) were introduced. The diameter of the stenosis was expanded from 01 ~ 03 cm to 18 ~ 21 cm. Dysphagia improved from 3 to 4 to 0 to 1 level. The authors believe that: for the multiple balloon catheter ineffective anastomotic stenosis, esophageal self-expanding metal stent treatment can be achieved immediate effect. For malignant stenosis, esophageal self-expanding metal stent treatment at the same time, together with radiotherapy and chemotherapy in order to improve the overall efficacy.
