Experimental substantiation of the original hernioplasty technique forrecurrent ventral hernias of median localization

Introduction. The reliability of non-tensioning alloplasty of ventral hernias of median localization is determined by the method of fixation of the mesh prosthesis. The aim of the study was a morphological and biomechanical assessment of the severity of fascial-muscular structures of the anterior abdominal wall in the rectus abdominal muscles in the aspect of the application of an original surgical technique for the treatment of patients with ventral postoperative hernias.

Materials and methods of research. The work was based on anatomical studies of 36 human corpses. Biomechanical parameters of native, scar-modified and reinforced fascial structures of the anterior abdominal wall with a skeleton thread according to the original surgical technique were studied at the ISS-500 stand using the Scaima ZF-500 force sensor. In the course of the study, radiography, computed tomography and ultrasonography were additionally used. Statistical analysis of the data was carried out using the Statistica 10 program.

Results. Five nodes were identified in the muscle-free areas and at the junction of the fascial structures of the anterior abdominal wall, which belong to the target structures of the median part of the anterior abdominal wall involved in the formation of hernias. The tensile strength and modulus of elasticity of the fascial structures of the anterior abdominal wall of various types of fascial structures of the anterior abdominal wall were studied. A comparative analysis of the results of the experiment showed that the highest indicators of tensile strength were in the scaraltered fascia, reinforced with a frame thread according to the original technique.

Conclusion. The proposed and patented technology of surgical treatment of ventral hernias of median localization increases the ability of tissues to withstand intra-abdominal pressure, which prevents the threat of relapse of the disease.
