Modification and results of alloplasty of inguinal hernias in the experiment

Abstract

The aim of the present study was to modify the alloplasty of inguinal hernia known as the Lichtenstein operation by forming a cuff around the spermatic cord at the site of the opening in the mesh, which protects it from the proliferation of scar tissue and subsequent deformation. Materials and methods. In the experiment on rats, the surgical intervention was performed according to the type of operations for congenital inguinal hernias. In this case, in the control group, the spermatic cord was in direct contact with the opening in the polypropylene mesh, while in the experimental group, the cuff was formed due to the muscular membrane and peritoneum of the peritoneal process. Operations on rats were performed under general anesthesia. For alloplasty, a polypropylene mesh measuring 2×2 cm was used with an incision along one edge for the passage of the spermatic cord. The mesh was fixed to the anterior abdominal wall in an on-line manner, the spermatic cord was located above the mesh. Results and conclusions. After the operation, the testicle stopped moving into the abdominal cavity on the right, which indicated the completeness of the performed plastic surgery. The modified method of alloplasty of inguinal hernias allows to significantly level out the swelling and scarring at the site of contact of the spermatic cord with the hole in the polypropylene mesh, and the implementation of additional measures to prevent the cicatricial process in the form of laser irradiation allows to improve the results of operations. The combined use of laser therapy in the treatment method in the experimental group prevents the observed early and late complications. Laser irradiation in the infrared spectrum due to deep penetration into the tissue promotes the resorption of wound infiltrate and improves local blood circulation. Improved local microcirculation leads to early and rapid healing of this wound.
