Efficacy of triamcinolone acetonide combined with recombinant bovine basic fibroblast growth factor in preventing scar formation after adult circumcision using a stapler device: A randomized controlled trial

Abstract

Background: This randomized controlled trial aimed to investigate the potential benefits of local application of triamcinolone acetonide combined with topical recombinant bovine basic fibroblast growth factor in promoting wound healing and reducing scar formation after circumcision using a stapler device. Methods: A total of 192 patients with phimosis or redundant prepuce were randomly assigned to either the observation group (n = 96) or the control group (n = 96). Both groups underwent circumcision using a stapler device. Postoperatively, the observation group received wet dressings of 2 mg/mL triamcinolone acetonide solution combined with topical recombinant bovine basic fibroblast growth factor until complete wound healing. The control group received saline wet dressings and standard postoperative wound care. Outcome measures included: postoperative edema, time to resolution of swelling at the incision edges, wound exudate, healing time, staple removal time and rate, scar formation, and patient satisfaction with penile cosmesis. Results: The observation group demonstrated significantly faster healing times and lower incidence of edema from the seventh postoperative day compared to the control group (P < .05). Furthermore, the observation group exhibited superior outcomes in terms of complete staple removal time, staple detachment rate, scar hypertrophy, and cosmetic scores using the modified Stony Brook Scar Evaluation Scale (P < .05). Patient satisfaction with penile cosmesis was also significantly higher in the observation group (P < .05). Conclusion: This study underscores the principle of “prevention over treatment” in scar management following stapler circumcision. The findings suggest that the combined use of triamcinolone acetonide and recombinant bovine basic fibroblast growth factor may be beneficial in reducing postoperative edema, improving scar formation, and enhancing patient satisfaction. However, further research is warranted to validate these findings, establish optimal treatment protocols, and ultimately assess the long-term efficacy and safety of this combined therapy.
