From 1989 to 1999 75 proximal resections of the stomach were performed. There were two variants of operation. In the first variant, invaginative valve from submucous-mucous membrane of the esophagus and the stomach was formed in the zone of gastroesophageal anastomosis. In the second variant, for prevention of anastomotic sutures eruption late after surgery and prophylaxis of valve expanding, duplication of muscular membrane on esophagus was formed. 58 patients were operated by the first variant, 17--by second variant. Postoperative lethality was 2.7% (1 patient died after operation of the first variant, 1 patient--after the second variant). In early postoperative period the complications were revealed in 8 (10.7%) patients. There was no insufficiency of anastomotic sutures. Mean hospital stay after operation was 14.7 +/- 3.5 bed days. Reflux-esophagitis of severe degree in remote period after operation was seen in 1 (1.3%) patient, catarral--in 4 (5.3%), all the patients were operated by the first variant.
