Abdominal Wall Reconstruction after Flap Surgery and the Effect on the Immune System.

Abstract:

Background:The aim of our study was to investigate the impact of abdominal wall reconstruction surgery on tissue anatomy and to explore how flap surgery influences the patient's immune status. Methods:Experimental abdominal wall defects were created in 8 Sus scrofa (swine) animal models. The animals were divided into two groups: 4 swine were euthanized one month after surgery for the biopsies retrieval purpose and the other 4 swine were kept alive and the collection of blood samples has been done 6 months after surgery. In order to evaluate the relative gene expression in operated-on animal cohorts we compared them with samples from 4 healthy swine used as controls. Results:The inflammatory process was present in all types of repairs. Collagen I deposition was higher in the flap repairs. The expression level for the genes related to immune response after 6 months from surgery was relatively similar to the control group except minor alteration registered in the case of two swine models. Conclusion:Our findings indicate a less pronounced proinflammatory response to surgical trauma in animal models after flap surgery. The postoperative levels of the inflammatory cytokines did not show significant differences after abdominal wall reconstruction using flap surgery.
