Materials on surgical treatment of 365 patients with various types of ventral hernias are discussed. The authors describe original methods of ventroplasty which they developed and approved . The methods comprise duplication of the whole peritoneal-muscular-cicatricial-aponeurotic complex of the abdominal wall by means of a double-row suture passed through all these layers and application of a third reinforcing row of sutures; whenever necessary, the operation is divided into two stages. Preoperative compression training of the abdomen is conducted in cases of a large hernia. Attention is focused on the need to choose the method of plasty for each individual patient, which makes it possible to avoid serious complications and fatal outcomes and produce good results of the treatment. Recurrences in large ventral hernias occurred in 8% of cases.
