Abstract (original English)

Introduction Stromal Vascular Fraction cells (SVFs) and Platelet Rich Plasma (PRP) are clinically proven to aid in cell regeneration and wound healing. The healing effects can be measured by the level of Epidermal Growth Factor (EGF). This study aims to investigate the effect of an SVFs and PRP combination on EGF levels in the anal trauma model. Method Twenty-eight adult Wistar rats were divided into 3 groups: Group A consisted of healthy rats as a normal control group; Group B and C underwent modified anal surgical trauma and repair. Group B was treated with saline only and Group C was treated with local injection of a combination of SVFs and PRP after anal surgical repair. The EGF level was subsequently assessed on days 1, 7, and 14. Results EGF levels were generally increased in Group C compared to Group B. A one-way ANOVA test result showed significantly increased EGF levels on days 7 (p = 0.038) and 14 (p = 0.018). Based on the linear regression test results, we found that local injection of PRP and SVFs after anal repair on an anal surgical trauma model can increase the EGF level in group C by 36.9% more than that of group B. Conclusion The combination of PRP and SVFs can increase the EGF level in the wound healing process of anal trauma. EGF is critical in the anal trauma healing process.
