The objective of this observational study is to analyze the factors influencing wound healing after anal fistula surgery and to assess the effectiveness of interventions in improving overall patient outcomes post-surgery. The primary questions this study aims to answer are: 1. Does the use of the growth factor (New Epi) contribute to accelerating wound healing, reducing the risk of infection, and enhancing patient recovery speed after surgery? 2. Do other factors, such as infection, nutritional status, diabetes, surgical methods, patient age and overall health, immune status, and lifestyle habits, affect the healing of surgical wounds?
