微波联合气囊扩张治疗良性食道狭窄

Treatment of Benign Esophageal Stenosis by Microwave Coagulation and Balloon Dilatation

目的 探讨微波及气囊扩张对良性食道狭窄的治疗效果。方法 通过胃镜检查明确食道狭窄部位及程度。根据狭窄的程度不同 ,采用内镜下气囊扩张或微波治疗 +气囊扩张治疗。结果 87例良性食道狭窄中 ,术后吻合口狭窄 3 7例 ,放疗术后狭窄 2 5例 ,化学烧伤后狭窄 2 2例 ,不明原因性狭窄 3例。其中气囊扩张治疗 66例 ,微波 +气囊扩张治疗 2 1例。治疗 1～ 43次 ,显效 78例 ( 89 65 %) ,有效 8例 ( 9 19%) ,穿孔 1例 ( 1 15 %)。结论 根据良性食道狭窄程度不同 ,采用内镜下气囊扩张或微波 +气囊扩张治疗 ,方法简单、廉价、安全、有效 ,适用于各种原因引起的食道狭窄 。

Objective To evaluate the therapeutic effects of microwave coagulation and balloon dilatation on benign esophageal stenosis. Methods The location and degree of esophageal stenosis was diagnosed by endoscopy. Balloon dilatation or microwave coagulation plus balloon dilatation were selected to treat esophageal stenosis according to the severity of esophageal stenosis. Results 87 cases of esophageal stenosis were caused by esophageal anastomosis after esophagectomy (n=37), radiotherapy(n=25), chemical damage(n=22) and unclear causes(n=3) respectively. 66 cases of esophagostenosis were treated by balloon dilatation and 21 cases were treated by microwave coagulation plus balloon dilatation. 78 cases of esophageal stenosis were significantly improved, 8 cases were improved, and 1 case happened esophageal perforation. Conclusion Endoscopic therapies including balloon dilatation or microwave coagulation plus balloon dilatation were efficacious to esophageal stenosis caused by various causes.
