FIELD: medicine.

SUBSTANCE: patients keep a diet with reducing an amount of liquid taken up to 1.5l a day that is compensated by the intravenous administration of solutions an amount and composition of which depends on a degree of water-electrolyte disturbances. Additionally, after bandage removal, the wound and edges of the fistulous passage is 5% potassium permanganate, which is then washed with 3% hydrogen peroxide. A mouth of the fistula and the wound edges are dried. That is followed by an aeration of the mouth of the fistula with a cooled plasma flow of nitrogen monoxide at a depth of 0.5cm in the therapeutic mode of 2000 mg/m³ and exposition of 1.5min. The mouth of the fistula and the wound edges are treated with a plasma flow of nitrogen monoxide in the concentration within the contact area with the wound surface of 1500 mg/m³ and time of exposure of 20 seconds per each 1 cm² of the surface. The mouth of the fistula and the wound edges are dried. The mouth is packed with the gauze swab. The fistulous wound is exposed to EHF waves with the pure noise spectrum and the provided integral power on the wound surface of 1.5 mcWt along the perimeter of the mouth at 15mm from the fistulous passage for 30 minutes. The swab is removed. The mouth and the surrounding skin is treated with zinc paste and covered with gauze swabs. The further bandages are performed in the similar way as the bandage wets with the intestinal contents, but no more than 2 times a day and at least once every 3 days.

EFFECT: safe and effective conservative treatment of the intestinal fistulas at any phase of the wound process that enables avoiding risks of surgical intervention and general anaesthesia by rapid reduction of skin maceration and perifocal inflammation surrounding the mouth and prevents them, stimulates the growths of granulocyte tissue and epithelisation of the fistuous wound.
