Characteristics of perianal abscess and fistula-in-ano in healthy children.
BACKGROUND
Probably because of the low frequency, perianal abscess (PA) and fistula-in-ano (FIA) in children older than 2 years have not been investigated except in those with a predisposing condition such as Crohn's disease. This study aims to summarize our experience about the characteristics and treatment of PA and FIA in healthy children.


METHODS
The charts of all children older than 24 months of age treated for PA and/or FIA from 1990 to 2003 were reviewed.


RESULTS
We found 40 patients, 37 of them boys (92.5%), ranging from 2 to 14 years of age (average: 7.19 years). At the first examination, the diagnosis was PA in 36 patients (mean age: 6.8 years; range: 2.3-13 years), and FIA in 4 patients (mean age: 10.8 years; range: 6-14 years). The primary local treatment of PA was drainage (needle aspiration in 26 patients, and incision and drainage in 4 patients) and local care in 6 patients. All patients received antibiotics. Overall, 29 children (80.6%) had primary cure of the abscess. Evolution included recurrent abscess in 3 patients (8.3%) and FIA in 4 patients (11.1%). Crohn's disease was diagnosed in only one boy with an abscess of long duration. No patient developed a new PA in another location or a recurrent FIA. Four male patients aged 6 to 14 years (range: 7.1 years) had a FIA of long duration. One patient underwent a fistulectomy. Crohn's disease was found in three other children and treated conservatively.


CONCLUSIONS
Drainage of PA by needle aspiration associated with antibiotics is effective in children older than 2 years of age with a low rate of evolution toward FIA. Associated pathology must be ruled out in children with FIA.
