Incidence and Treatment of Parietal Prosthesis Infections: A Retrospective Study of 793 Hernia and Eventration Cures

The cures of hernias and eventrations by prosthesis expose to the risk of infection of the prosthetic material. We carried out a retrospective study about 793 cures of hernia and eventration that were operated on in our service and treated by the establishment of the prosthesis between 2015 and 2020 with the aim of specifying the risk factors for prosthesis infections and the therapeutic modalities. The results were as follows: 9 cases of prosthesis infection (1.15%) are noted with 6 cases (66.7%) after inguinal hernia surgery and 3 cases (33.3%) after hernia surgery. The time to onset of the infection was early in 5 cases, medium in 3 cases and late in one case. A radical treatment was carried out in 4 patients and conservative in 5 cases. The incidence of prosthesis infection is variable between 0.2% and 8%; it is around 1.15% in our series, which is consistent with the results of the literature. This formidable complication requires the rigorous application of aseptic measures as well as a good indication of the use of parietal prostheses.
