FIELD: medicine, abdominal surgery. SUBSTANCE: one should apply sutures by using greater omental flap. Moreover, flap's material edge should be sutured to parietal peritonium being behind defect's posterior edge. Then one should suture defect's posterior edge to the flap. Defect's anterior edge is sutured to greater omental flap by keeping intestinal diameter in defect's area. The second row of sutures is applied onto serous-muscular layer of intestinal wall and omental flap. Flap's medial edge is sutured to free strip of large intestine. The method enables to close considerable defect in large- intestinal wall in weakened patients. EFFECT: higher efficiency of operation. 1 cl, 1 dwg
