Effects of platelet rich plasma on the gastric serosal surface neomucosa formation: an experimental rodent model

Abstract

Abstract Background Autologous platelet rich plasma (PRP) is the platelet concentration obtained from thrombocytes in the plasma. During the healing process, the platelets are activated and then release the granules which stimulate the inflammatory cascade and healing process. Platelet derived growth factor, vascular endothelial growth factor (VEGF), transforming growth factor β (TGFβ), epidermal growth factor (EGF) and fibroblast growth factor (FGF) are valuable markers used for cell regeneration. The aim of this study was to investigate the potential effects of PRP treatment on the neomucosa formation, a potential technique for increasing the intestinal surface area in patients with short bowel syndrome (SBS). Materials and methods Thirty-two male Wistar-Hannover rats were divided into: sham, control, PRP-treated and last group for PRP preparation (n=8). Plasma levels of VEGF, TGFβ, EGF and FGF were quantified by ELISA. En-bloc resection of anastomotic part was performed and stained with hematoxylin-eosin. Results VEGF, FGF, TGFβ and EGF levels were found significantly increased in PRP-treated group compared to others (p<0.001). Neomucosa formation was observed in experimental groups but the area increased significantly in PRP group, compared to other groups (p<0.001). Conclusion PRP therapy in gastrointestinal anastomoses is truly beneficial and surgically applicable treatment in SBS patients.
