Comparative Approaches of Antibiotic Therapy and Surgical Intervention in Managing Recurrent Perirectal Abscess in Children Under Two Years Old

Background: Recurrent perirectal abscesses in children under 2 years pose management challenges due to high relapse risks, with limited evidence comparing long-term outcomes of antibiotic therapy versus surgical drainage. This study aimed to compare antibiotic treatment approaches and surgical interventions in managing this condition. Methods: This retrospective cohort study analyzed 336 medical records of children under two years old with perianal abscesses treated at Hazrat Masoumeh Children’s Hospital from 2012-2019. Patients were divided into three groups: antibiotic treatment only, spontaneous drainage, and incision and drainage. Data, including demographics, abscess characteristics, and treatment outcomes (recurrence, fistula formation), were analyzed using SPSS software version 26. Results: A retrospective cohort study of 336 children with perianal abscesses found no significant differences in age, weight, sex, or nutritional status among the three treatment groups (P>0.05). However, statistically significant differences were observed in abscess location (distance from the anus) and size, with the incision and drainage group having larger and more distally located abscesses (P<0.05). Colic was less prevalent in the antibiotic-only group. The spontaneous drainage group had a significantly higher recurrence rate (37%). Antibiotic type distribution was similar across groups. The antibiotic-only group showed symptom resolution within 3-10 days, averaging 6 days. Conclusion: In general, according to the lowest rate of recurrence in the group receiving antibiotics and the average duration of short treatment of 6 days, the antibiotic approach is the preferred and primary method for the treatment and prevention of abscess recurrence.
