INDICATIONS AND CHOICE OF TECHNOLOGY FOR POLYMERIC MATERIALS IMPLANTATION IN THE ABDOMINAL WALL FOR PREVENTION AND TREATMENT OF POSTOPERATIVE VENTRAL HERNIAS

Abstract

The absolute indication for primary covering a laparotomic wound with a synthetic prosthesis is complicated anatomic and functional insufficiency. There are relative indications for this surgery, such as old age, III–IV degree of obesity, repeated laparotomy in location of the same scar, covering a laparostoma in patients treated with programmed sanation of the abdominal cavity and laparotomy in patients treated with radiology or chemotherapy methods. Lowering of functional activity of ribosomal genes is a reason of the anterior abdominal cavity weakness, its progress causes lowering in skin and aponeuroses composition I–III types of collagen. We examined the speed of growing and differentiation of connective tissue after implantation endoprosthesis made of lavsan, polypropylene, polyvinylidene fluoride, polytetrafluoride ethylene. It was proved that the polyvinylidene fluoride mesh had the best biocompatibility. The progress of wound implantation process could be predicted by dynamics of cytokine profile, temperature, leukocyte and exudative reactions of a patient. The best insensitiveness to infection belonged to a standard polypropylene endoprosthesis, it could be used for covering a hernia defect in patients with strangulated hernias. The fact that urine poured into the operation wound during urinary system surgery combined with lateral hernias of abdomen was not a contraindication for endoprosthesis.
