自胀式全覆膜可回收金属内支架在良性食道狭窄中的应用

The application of covered self-expendle retrievable metallic stents in treatment of benign esophageal strictures

目的 :探讨自制可回收金属覆膜内支架在缓解良性食道狭窄中的作用及效果。 方法 :在X线监视下 ,采用经口腔内支架置入回收术。 结果 :本组 15例患者支架均成功回收 ,吞咽困难缓解率达 10 0 % ,有 2例患者于术后 3个月再次发生食道狭窄 ,行第二次可回收支架置入术 ,症状缓解。 1例患者在术中行球囊扩张时造成食道纵隔瘘 ,被迫置入永久性支架。所有患者在术后 3个月、6个月复查时 ,食道均扩张良好 ,无严重并发症发生。 结论 :用可回收全覆膜支架治疗良性食道狭窄是一种安全有效的方法。

Objective: To evaluate the treatment effect of covered self-expendle retrievable metallic stents in treatment of benign esophageal strictures. Methods: In all cases peroral intubation of the stents were performed under X-ray. Results: All stents were successfully placed and retrieved. Remittent rate of dysplagia was 100%. Only 2 cases again with esophagas stenosis when checked after 3 months replaced again and symptoms were remittented.1 case was made esophageal mediastinal tube during operating ballooning-diliated and was forced to implant permanent stent. In all cases esophageal were expendled well when re-checked after 3 months and 6 months respectively and didn't find any rital complications. Conclusion: It's a safe and efficient method that treating esophagus nonmalignant stricture covered self-expendle retrievable metallic stents.
