Abstract. In the period from 2001 to 2017, 1419 patients with ventral and postoperative ventral hernia were operated on. The unsatisfactory results of the surgical treatment of this pathology were due to a number of disadvantages: the choice of an inadequate method of hernioplasty in a specific clinical situation, an incomplete revision of the muscle-aponeurotic layer of the anterior abdominal wall, especially in patients with postoperative veterinary hernias, concomitant syndrome of undifferentiated connective tissue dysplasia and obesity, and weak points, the wrong choice of the type of mesh implant (“light” or “heavy” polypropylene mesh) and its size, the choice of an inappropriate type of suture material, as well as the high invasiveness of surgical intervention. Based on the given causes of complications in the operated patients with a high risk of their development, we have made a technical improvement of the existing methods of hernioplasty and development of new ones, which significantly reduced the number of postoperative complications and increased the safety of performing surgical interventions in patients with ventral and postoperative ventral hernia.

Purpose. Based on the results of the analysis of surgical treatment of patients with comorbid conditions for primary and incisional ventral hernias to develop technical prerequisites for improving the safety of surgical interventions in this category of patients.

Methods. Іn the period from 2001 to 2017, an in-depth comprehensive clinical-instrumental and laboratory examination of 1419 patients with primary ventral hernia (PVH) and postoperative ventral hernia (PVH) was conducted. The patients were divided into groups according to the periods of surgical treatment of patients. For this purpose, two periods were formed: from 2001 to 2009 and from 2010 to 2017. At the first period, 597 (42.07%) patients were examined and operated on. These patients formed a comparison group. The main group corresponding to patients who were treated in the period from 2010 to 2017 was 822 (57.93%) people.

Results. Developed techniques for performing retromuscular allogernioplasty, which were based on controlled visualization of suturing when fixing polypropylene mesh to the posterior leaf of the vagina of the rectus muscle, allowed us to reliably and safely place and secure the implant in the retromuscular space, significantly reduce the trauma and duration of surgery.

Kind of treatment using the mesh allograft with a liposomal complex with included antibacterial and immunosuppressive agents during the operation on the "onlay" method significantly reduced the number of local infectious complications. The location of the PRF membrane over the polypropylene mesh during retromuscular allogernioplasty improved neoangiogenesis at the mesh implantation site, increased fibroblast activity and the formation of collagen fibers around the mesh material, which provided maximum integration of the "light" abdominal wall with polypropylene tissue.

Conclusion. These features of the dynamics of the used methods of surgical interventions and types of polypropylene nets with an individualized approach to each patient were reflected in a significant reduction in the number of both early local and general late postoperative complications, which improved the effectiveness of surgical treatment of patients with primary postoperative ventral hernias.
