Insights
Surgery for pediatric perianal abscesses can be effective. Anal fistula probing predicts success, while a history of abscesses indicates recurrence risk in children.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Proctology
Background:
- Perianal abscess management in children lacks definitive surgical guidelines.
- Recurrence data after pediatric perianal abscess surgery is limited.
Purpose of the Study:
- To assess surgical outcomes for pediatric perianal abscesses.
- To identify predictors of recurrence following surgical intervention.
Main Methods:
- Retrospective review of pediatric patients (<14 years) undergoing surgery for perianal abscess from 2000-2018.
- Analysis of recurrence rates and associated clinical factors.
Main Results:
- 26% of 103 patients experienced recurrent perianal disease (abscess or fistula).
- Anal fistula probing (OR=22.08) was independently associated with treatment success.
- History of perianal abscess (OR=0.032) predicted treatment failure.
Conclusions:
- Anal fistula probing is a key predictor of successful surgical outcomes in pediatric perianal abscess.
- A prior perianal abscess history signifies a higher risk of recurrence.
- Surgical recommendations include fistula probing and fistulotomy when indicated.
Purpose:
The role of surgery in managing perianal abscesses in the pediatric population is debatable, and data on recurrence risk is rare. This study aimed to evaluate the efficiency of surgery for a perianal abscess in children and identify parameters that predict recurrence.
Methods:
We performed a retrospective review of all children younger than age 14 requiring surgery for a perianal abscess from 2000 to 2018.
Results:
Out of 103 enrolled patients, 27 (26%) had recurrent perianal disease. Recurrences appeared after a median of 5 months (range: 1-18 months), in 12 cases as perianal abscess and 15 cases as fistula in ano. Anal fistula probing was performed in 33% of all patients, of which 16 (15%) underwent fistulotomy. In univariate analysis, older age (p = 0.034), fistula probing (p = 0.006) and fistulotomy (p = 0.009) was associated with treatment success. History of perianal abscess, multilocal occurrence, and the presence of enteric flora in wound swabs was associated with treatment failure (p = 0.002, OR = 0.032). In multivariate analysis, anal fistula probing was independently associated with treatment success (p = 0.019, OR = 22.08), while the history of perianal abscess was associated with treatment failure (p = 0.002, OR = 0.032).
Conclusion:
Our study identified probing for fistula as a predictor of therapy success, while the history of perianal abscess was identified as a predictor of treatment failure. Therefore, in all children with perianal abscess, fistula probing and if present, fistulotomy should be performed.
