FIELD: medicine. SUBSTANCE: method involves carrying out selective proximal vagotomy. The pylorobulbar segment is removed placing the inferior resection boundary 15-20 mm below the stenosis ring of the pylorus. Pylorus-like constrictor is built in the gastroduodenal anastomosis area. Visible blood vessels of the submucous layer are sutured with separate sutures all over the whole circumference of the distal portion of the stomach stump 18-20 mm below the distal boundary of the created constrictor. The seromuscular envelope of the duodenum is circularly cut 10-12 mm distal with respect to resection boundary, separated and removed all over the whole circumference as a strip of 12-15 mm in width. Then 4-5 interrupted sutures are put in over the posterior anastomosis semicircle. The inferior boundary of the created constrictor is taken into the suture on the stomach. The submucous layers of the posterior anastomosis wall are joined by suturing 18- 20 mm apart from the first row of sutures. Mucous membrane of the posterior and anterior stomach and duodenum stump semicircle are circumferentially cut off. Submucosubmucous suture is applied upon the anterior semicircle of the anastomosis. Then, separated interrupted sutures are put in passing through the inferior boundary of the created muscular constrictor of the stomach stump and the superior boundary of the seromuscular membrane of the anterior duodenal semicircle. The mucosubmucous layers of the stomach and duodenal stump are invaginated into the lumen of the latter one, forming circular artificial valve. EFFECT: normalized motor evacuation stomach function; prevented postresection complications. 7 dwg
