MICROBIOLOGICAL AND HISTOLOGICAL CHANGES IN CASE OF REMOVAL OF INFECTED MESH IMPLANTS AFTER HERNIOPLASTY

Abstract

Purpose of research - to study microbiological and histological changes in tissues during removal of infected mesh prostheses after hernioplasty performed by various methods.Materials and methods. The study included 69 patients, which required the removal of the previously installed mesh prostheses at hernioplasty in connection with their infection and formation of cutaneous fistulas. All patients were divided into 2 groups depending on the methods of removal of the prosthesis: the main and the comparison group. Results. In the main group of patients it was noted statistically significant reduction of microbial number in relation to the comparison group at all stages of prosthesis removal. Morphological study of the bed tissue of the removed prosthesis showed that pronounced histological changes, characterized by the presence of voids and foreign bodies (remains of prosthesis) in granulation tissue, were present in patients of the comparison group. In patients of the main group the density of granulation tissue was significantly higher and the remains of the prostheses were noted in individual cases.Conclusion: As a result of research it is revealed that ultrasonic cavitation of antiseptic solution allows to effectively eliminate microflora in purulent cavities, as well as to remove the infected prostheses with preservation of high density of granulation tissue and without damage to subtissues.
