Modifications in the production of cytokines and growth factors in drainage fluids following mesh implantation after incisional hernia repair.
BACKGROUND
The aim of this study was to evaluate changes in the production of some cytokines (interleukins [ILs]-6, -10, -1, and -1ra), vascular endothelial growth factor, and beta-fibroblast growth factor after polypropylene mesh implantation.


METHODS
Twenty female patients were divided into 2 groups. In 1 group, hernia repair was performed with conventional sutures (CR), whereas in the other group polypropylene mesh (MR) was used. Growth factors and cytokines production was analyzed in wound drain fluids based on the amount produced during 24 hours.


RESULTS
IL-1 increased substantially in MR patients on postoperative days 1 and 2. IL1-ra and IL-10 production was always significantly higher in CR patients. IL-6 production did not show any considerable difference between the 2 groups. Vascular endothelial growth factor production was significantly higher in the MR than the CR group at all time points, whereas beta-fibroblast growth factor production was higher in the MR than the CR group only on postoperative day 1.


CONCLUSIONS
Our data suggest that different surgical procedures induce various levels of inflammation and that implantation of prostheses significantly stimulates the inflammatory response.
