An improved method for the formation of a cuff-like end-to-side vertical anastomosis between the esophagus and intestine with antireflux properties was applied in gastrectomy in 142 patients with predominantly stage III gastric carcinoma. The postoperative mortality was 3.5%. Microincompetence of the sutures of the esophago-intestinal anastomosis, which did not result in death, was encountered in 2.1% of patients. Reflux esophagitis occurred in the late-term period in 9.3% of patients, cicatricial strictures of the anastomoses developed in none of the cases. The method suggested for the formation of an esophagointestinal anastomosis is simple, reliable, and may be successfully used in gastrectomy.
