探讨食管贲门癌术后吻合口良性狭窄的治疗方法及效果。采用锥形硅胶扩张器和气囊扩张器，在纤维内镜直视下，对３２ 例食管贲门癌术后吻合口良性狭窄患者进行５２ 例次扩张治疗，症状改善率１００ ％ ，显效率９３ ．７％ ，无明显并发症。表明该法安全、可靠。影响扩张效果因素：狭窄段过长、扭曲成角及反复再狭窄。对反复狭窄仍需支架治疗 To investigate the treatment of benign stenosis anastomotic after esophageal and cardiac cancer surgery. Conical silicone expanders and balloon dilators were used to perform 52 dilations for 32 patients with benign stenosis of anastomotic squamous cell carcinoma under fiberoptic endoscope. The improvement rate of symptoms was 100%, and the effective rate was 93. 7%, no significant complications. It shows that the law is safe and reliable. Factors affecting the expansion effect: excessively long narrow segments, distorted angulation, and repeated restenosis. Stent treatment is still needed for repeated stenosis
