Video-assisted anal fistula treatment (VAAFT) combined with ozonide oil dressing: standardization of technique in pediatric patients

Anal fistula and perianal abscess are commonly acquired anorectal pathologies in children. Surgical treatment options commonly adopted are fistulotomy, fistulectomy, cutting seton placement, and more recently video-assisted anal fistula treatment (VAAFT). Optimal postoperative wound dressing remains debated. This study aimed to report our series of pediatric patients, who received VAAFT and postoperative wound dressing using ozonide oil. All patients who underwent VAAFT between August 2018 and May 2023 were included in the study. Demographics, clinical features, pre-operative imaging, surgical details, outcome, and mid-term outcome data were retrospectively reviewed for each patient. All VAAFT procedures were performed under general anesthesia and using a 10-Ch fistuloscope. Thirty-three VAAFT procedures were performed in 30 patients over the study period. The median patient age was 5.7 years (range 1.75–14). Anal fistula was idiopathic in 26/30 (86.6
