BackgroundThere are varying opinions on the feasibility of the placement of synthetic materials in contaminated surgical fields. The aim of this study was to investigate the outcomes of the use of a commercially available composite mesh in the presence of abdominal infection.MethodsTwenty-four hours after the induction of experimental peritonitis, 20 rats were randomized into 2 groups of 10 subjects. After abdominal cleansing with a second laparotomy, the abdomen was closed with running sutures in the control group and the composite mesh was applied in the experimental group before closure. The rats were followed up for findings of sepsis, mortality, and wound infection. On the 28th day, the rats were sacrificed and evaluated for abdominal infection, abdominal adhesions, and bacterial growth in the mesh and tissue cultures.ResultsThe mortality rate was 0% and 30% in the control and mesh groups, respectively (p=0.21), and the wound infection rate was 20% and 57.1% (p=0.162). In the mesh group, the adhesions were significantly more intense (p=0.018) and significantly more microorganisms proliferated in the tissue cultures (p=0.003).ConclusionThe significant increase in the intensity of adhesions and bacterial proliferation, as well as the higher rate of mortality and wound infection in the mesh group indicated that this composite mesh cannot be used safely in the repair of abdominal defects in the presence of abdominal infection.
