FIELD : medicine.SUBSTANCE : invention refers to medicine, namely to neonatal surgery, and can be used in reconstruction of gastrointestinal tract after gastrectomy in newborn. Treatment is carried out in two stages. At the first stage, an upper transverse laparotomy and a total necrotized stomach resection are performed. Suspended jejunostomy is brought out on anterior abdominal wall, for this purpose nutrient probe Ch8 is placed into intestinal cavity at distance of 15 cm in 10 cm from ligament of Treitz. Postoperative period involves an intensive respiratory and antibacterial therapy, correction of water-electrolyte disturbances, complete parenteral nutrition. Second reconstructive stage of the operation is performed 10 days later. Relaxation is performed under general anesthesia after 2-fold surgical procedure. Abdominal esophagus is mobilized at a distance sufficient to apply an anastomosis without tension. Isolated jejunal loop is formed by cutting off at 20 cm from the Treitz' s ligament, and the loop is passed through a mesentery of the transverse colon. Single-line oesophagoenteroanastomosis is performed. Then a false jejunostomy is brought out on an anterior abdominal wall, for this purpose a nutrient probe Ch8 is placed into the intestinal cavity at distance of 15 cm. In the postoperative period on 4th day, enteral microfluid feeding into the jejunostomy is started. On 10th postoperative day – partial bolus oral feeding with transition to full bolus in 3 weeks.EFFECT : invention provides reducing time between stages of operation and length of hospital stay, prevention of postoperative complications, possibility of early enteral nutrition, eliminates additional surgical intervention.1 cl, 2 dwg, 1 ex
