食管、贲门癌切除术后吻合口狭窄是常见的术后远期并发症 ,发生率为 0 .5 %～ 3.7% [1 ] ,特别是使用机械吻合后吻合口狭窄的发生率增高 ,其原因可能由于器械挤压食管胃壁造成组织损伤 ,最后纤维化而致吻合口狭窄。为探讨“梅氏”扩张器治疗食管、贲门癌切除术后吻合口狭窄的疗 Esophageal and cardiac resections of anastomotic stenosis is a common long-term postoperative complications, the incidence rate of 0.5% to 3.7% [1], especially the use of mechanical anastomotic stricture anastomosis increased the reason, the reason May be due to equipment squeeze esophageal stomach tissue damage caused by the final fibrosis caused by anastomotic stenosis. To explore the “Mei’s” dilator treatment of esophageal and cardiac resection of anastomotic stenosis after treatment
