Abstract: the analysis and pathogenetic substantiation of the feasibility of using non-tension plastic surgery in ventral hernias of the abdominal wall with a defect size of more than 10 cm was carried out. Preparation for a non-tension plastic surgery consists in introducing the oxygen-air mixture at 1: 1 intervals into the abdominal one the cavity with an increase in the volume of the injected gas mixture with each subsequent introduction of 300-500 ml. Preoperative preparation is carried out until the degree of stretching of the abdominal wall necessary for hernioplasty with local tissues without tension is achieved according to the formula: M = (d1-d2) × 1.3, where d1 is the circumference of the abdominal wall in the zone of maximum value of the hernia gate; d2 – incomplete circumference at the edges of the hernial ring with deduction of a hernia size defect; 1.3 – the correction coefficient of reduction of stretched abdominal wall tissue after hernioplasty due to their elasticity. According to this technique, hernioplasty was performed in 23 patients. In the postoperative period, 2 (8.7%) patients developed an infectious complication of a wound. The rest of the postoperative period was uneventful. 4 months after surgery, no complications were noted. It is advisable to continue research in patients with ventral hernias with more severe comorbidities.
