Core Tip

Core Tip: This retrospective study evaluated the predictive factors for postoperative anorectal abscess recurrence and proposed a new classification to guide surgical procedures, including incision and drainage alone or a combined concurrent fistulotomy. We found that the recurrence rate of fistula-prone and non-fistula-prone abscesses (FPAs) was 81.0% and 23.5%, respectively. Additionally, we demonstrated that FPAs, a duration ≥ 7 days from symptom onset to surgery, chronic diarrhea, and local anesthesia were independent risk factors for postoperative anorectal abscess recurrence. Our findings support using this new classification to guide the choice of surgical procedures for treating anorectal abscesses.
