Abstract:Objective To investigate the effects of Compound Huangbai Liquid for sitz bath on wound healing and serum levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) following mixed hemorrhoid surgery.Methods A retrospective analysis was conducted on 102 patients with mixed hemorrhoids who underwent surgical treatment at Hefei First People’s Hospital from January 2023 to December 2024. According to postoperative treatment, the patients were divided into a Compound Huangbai Liquid group (n = 55) and a Kangfuxin Solution group (n = 47). Wound healing efficacy, healing time, and healing rate were compared between the two groups. Additionally, wound edema, exudation, and granulation tissue scores, as well as traditional Chinese medicine (TCM) symptom scores (difficulty in defecation, fresh blood during defecation, and anal pain/swelling), serum levels of VEGF and bFGF, and safety were evaluated.Results The overall effective rate in the Compound Huangbai Liquid group was higher than that in the Kangfuxin Solution group (P < 0.05). The Compound Huangbai Liquid group had a shorter wound healing time and a higher healing rate (P < 0.05). The changes in wound edema, exudation, and granulation tissue scores before and after treatment were greater in the Compound Huangbai Liquid group than in the Kangfuxin Solution group (P < 0.05). Similarly, the changes in TCM symptom scores (difficulty in defecation, fresh blood during defecation, and anal pain/swelling) and serum VEGF and bFGF levels were greater in the Compound Huangbai Liquid group than in the Kangfuxin Solution group (P < 0.05). No obvious adverse reactions were observed in either group.Conclusion Compound Huangbai Liquid for sitz bath promotes wound healing after mixed hemorrhoid surgery, increases serum VEGF and bFGF levels, and has a good safety profile.
