【摘要】 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（＜０２ｃｍ）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０１～０３ｃｍ扩张至１８～２１ｃｍ。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。更多还原

【Abstract】 The paper discussed the experiences from 5 cases with upper-digestive tract benigne or malignant strictures treated by self-expanding metallic stent and the methods of inserting the guide wire for severe stricture (<0.2cm) and the use of self-expanding metallic stent.Diameters of stricture were expanded from 0.1～0.3cm to 0.8～1.8cm and dysphagia relieved from 3～4 grade to 0～1 grade after treating.The authors think:some patients with unsatisfied outcome resulting from balloon expanding could get good curative effect by using self-expanding metallic stents.For the malignant stricture cases,using self-expanding metallic stent combined with chemical treatment at the same time could increase the total curative effect.更多还原
