FIELD: medicine, surgery.
SUBSTANCE: one should perform cross-sectional anterior-lateral seromyotomy, coagulate the vessels of submucous layer, lance duodenal lumen, carry out parietal mobilization of posterior wall towards pylorus, dissect posterior wall by layers from mucous membrane towards serous one, dissect longitudinally scar-altered wall from two sides against the ulcer up to altered tissues, then it should be dissected circularly. One should apply a single-row anastomosis. In peculiar case, one should apply duodenoduodenoanastomosis. In peculiar case, at involving distal muscular portion of pyloric bagasse into scar process it is necessary to perform distal pylorolysis, form pyloroduodenoanastomosis, at its developing one should capture serous, mucous and submucous pyloric membranes by not capturing a muscular one. The method enables to conduct economic resection, keep pyloric function, prevent the damage of choledochal terminal department and pancreatic duct.
EFFECT: higher efficiency of duodenal resection.
