Hernia of abdominal wall found in 10% of the adult population and take 3-4 place in the structure of surgical diseases. Each year, on the planet performed over 20 million operations of hernia, which is 10-15% of all interventions. For plastic hernias of the abdominal wall during 1 year used 1 million synthetic fishing nets. In Ukraine, about 13 thousand operations performed on strangulated hernias of the abdominal wall when there is inflammatory exudate, infection in the wound. Purpose. In the experiment to prove the applicability of polypropylene mesh for hernioplasty in cases of infection, phlegmon of hernia sac. Materials and methods. The experimental research was conducted on 150 white male rats breed "Wistar" weighing 250-300 g, same age, without disease, detained in accordance with generally accepted standards, at least 10 days before the experiment. In carrying out the experiment followed the major domestic and international standards according to national "general ethical principles of animal experimentation" (Ukraine, 2001). The open question of herniology is possibility of surgical treatment of hernia defect of abdominal wall at the hurt hernia, infecting of wound, phlegmon of hernia. For the study of problem, in an experiment on 150 white rats with the phlegmon of hernia complex research of features of flow of reparative process on an area the allogernioplastic polypropilene net of Linteks esfil is executed. The rats were divided into 3 groups: 1-st group – the plastic arts of hernia by the net of polypropylene of Linteks esfil standard; 2 group – the plastic arts by the net of Linteks esfil easy; 3 group – the plastic arts by the net of Linteks esfil heavy. The opened sore was washed by 0,02% solution of Decasan, Оctenisept farblos (Germany), intramuscular entered 1 ml of Imunophan, Ceftriaxon during a week. A positive dynamics was marked toward diminishing of contamination by microorganisms to 7 days after an operation. There were inflammatory changes in three groups: it was swollen hyperemia of tissues, serous-hemorrhagic excretions from a wound. On the 14th  days reticulated implant was densely fixed to the muscles and was in the thin layer of connecting fabric with more mature granulation fabric. In 21 day reticulated implant surrounded connective capsule which consisted of well-organized collagen fibres with the insignificant external signs of inflammation.  The results of experimental researches confirm possibility of application of reticulated implant for the plastic arts of hernia defect in the phase of inflammation which more frequent meets at the hurt hernia. At presence of festerings excretions in hernia, the use of polypropilene net for the plastic arts must be accompanied careful rehabilitation of wound, abdominal region with adequate antibacterial therapy. Conclusions: The reaction of tissue to implant mesh matches with reaction of tissue bordering to necrotic cells, and the presence of an infected hernia does not worsen the conditions of integration polypropylene implant with tissues. Strengthening mesh in tissues observed at 21 day, and the most pronounced effects of fixation - on 90 days after alloplastic hernioplasty of the hernia defect. The results of experimental researches confirm the possibility of using plastic mesh implants for hernia defect in phase of inflammation that often occurs in strangulated hernia.

Numerous methods of plastic surgery of inguinal hernias with own tissues, which were developed by surgeons, gave relapses up to 35%. A large number of relapses in the treatment of inguinal hernias with tension methods forced surgeons to look for new ways to solve this problem. Without pathological changes in the deep inguinal ring, a hernia cannot occur, and this leads to the conclusion that all existing methods, which are aimed at strengthening only the front wall of the inguinal canal, are pathogenetically unfounded and often a recurrence of the hernia can be expected. Therefore, a justified operation for various types of inguinal hernia is the strengthening of the deep ring and the back wall of the inguinal canal. Changing the concept of the approach to the treatment of inguinal hernias should be aimed at minimizing trauma and take into account the pathogenetic features of the development of hernias. The reason for the development of inguinal hernias is expansion, destruction, functional insufficiency of deep inguinal openings: medial and lateral. The back wall of the inguinal canal does not have a protective function when intraperitoneal pressure increases and cannot resist hernia formation. At the same time, its weakening, destruction can contribute to the increase of the internal inguinal opening. Although we did not come across any publication that gave an example of a hernia exiting directly through the back wall of the inguinal canal. Based on our own clinical experience, as well as the processing of a large number of literary sources, we offer a modified type of Lichtenstein's operation in the following interpretation: a typical incision of the skin and subcutaneous tissue with the opening of the aponeurosis of the external oblique abdominal muscle; mobilization of the spermatic cord; mobilization of the hernia sac, its opening, stitching at the base and removal. With a direct inguinal hernia, if the bag is small, there is no need to remove it. Revision of the internal inguinal ring in case of an oblique hernia and, if necessary, sewing it to the required size (the tip of the little finger should pass between the cord and the ring). Revision of the medial deep ring in direct inguinal hernia and its suturing "tightly" over the hernial protrusion. Prepare a mesh implant so that its dimensions cover both deep holes, dissect it according to our proposed method. Fix the net to the deep ring using the described method. Sew the lower part of the mesh with an overlap of 1-1.5 cm to the pubic bone, fix the lateral edge of the implant to the pubic ligament with a wrapping suture or knotted single sutures. Above the spermatic cord, the legs of the dissected implant are sewn together and sewn to the aponeurosis of the external oblique muscle of the abdomen from below. The medial edge of the mesh is sewn to the internal oblique muscle and to the aponeurosis of the external oblique muscle in the manner described above. The middle part of the mesh is fixed to the sewn medial deep inguinal ring and to the middle of the inguinal canal with separate knotted stitches. We lay the spermatic cord on the mesh, over which we sew the aponeurosis of the external oblique muscle of the abdomen, subcutaneous tissue and skin. In our opinion, the method of surgery proposed by us for direct and oblique inguinal hernias is the most optimal, minimally traumatic, which best meets the modern requirements of the pathogenesis of the disease. But even this method of plastic inguinal hernias is not ideal and needs constant improvement.
