目的　为避免或减少食管胃吻合术后吻合口狭窄、返流性食管炎及吻合口瘘 ;设计了食管胃椭圆形吻合法。方法　实验与临床均随机分为椭圆形吻合法组与传统吻合法组进行对比研究。结果　椭圆形吻合法组无论是吻合口径、组织愈合过程、抗返流、食管粘膜充血、水肿及食管粘液pH值测定等方面均优于传统吻合法 (P <0 0 5)。结论　椭圆形吻合法是食管胃消化道重建中更为理想的手术方法 Objective To avoid or reduce esophageal and anastomotic stenosis, reflux esophagitis and anastomotic fistula; designed esophageal oval anastomosis. Methods Both experimental and clinical randomized patients were randomly divided into two groups: oval anastomosis group and traditional anastomosis group. Results Oval anastomosis was superior to traditional anastomosis (P <0.05) in terms of anastomotic caliber, tissue healing process, anti-reflux, esophageal mucosal congestion, edema and esophageal mucus pH measurement. Conclusion Oval anastomosis is a more ideal surgical method for reconstruction of esophageal and gastric digestive tract
