[Non-reflux esophago-gastric anastomosis]

A new method of performing esophago-gastric anastomosis in proximal gastric resection is proposed. It is based on a circular enveloping of the anastomotic zone with the "spurs" of the greater curvature of the stomach. The method was designed and experimentally tested on nonfixed cadavers, as well as on the 60 dogs. Esophago-gastroscopy, histological examination of the anastomotic zone and mucosa of esophagus were used to evaluate long-term results. The method was used in 8 patients with proximal gastric resections. Good permeability of the esophagus and lack of signs of anastomotic insufficiency were found. The method is advocated for the use in clinical practice to provide safe peritonization of anastomotic zone and prevent gastroesophageal reflux.
