食管术后良性狭窄的介入治疗

Interventional therapy for benign strictures after esophagectomy

目的探讨介入治疗在食管术后良性狭窄中的安全性及临床疗效。方法对32例食管术后良性狭窄的患者行介入治疗术，其中球囊成形术26例59次，每例扩张1—4次不等；支架植入术6例8次，共置入可回收覆膜金属支架8枚。结杲26例行球囊扩张患者，经1次扩张治愈者4例，2次13例，3次7例，4次2例，术后所有患者梗阻症状均明显改善。6例支架植入术患者中4例出现支架上口处明显狭窄。结论球囊扩张结合可回收覆膜金属支架具有可重复治疗，对于食管术后良性狭窄的治疗安全有效。

Objective To explore the safety and clinical curative effect of interventional therapy for post-operative benign esophageal strictures. Methods Interventional therapies were performed on 32 patients with post-operative benign strictures, of them, balloon tympanoplasty was used in 26 cases 59 times（ 1 to 4 times per case ）, and stent implantation in 6 cases with 8 retrievable metallic-covered stents. Results In 26 cases of balloon dilatation, 4 cases were cured in 1 treatment, 13 cases in 2 treatments, 7 cases in 3 treatments and 2 cases in 4 treatments, and the constrictive manifestations were all improved. In 6 cases of stent implantation, stenosis above the stent was found in 4 cases. Conclusion Balloon dilatation combined with stent implantation is a safe and effective therapeutic method for post-operative benign esophageal strictures.
