Perianal sepsis in children.
BACKGROUND
Perianal sepsis is a relatively common surgical problem in children and yet the contribution of rare aetiological factors, the frequency of fistula formation complicating perianal abscess, the significance of bacteriological findings and the optimum treatment of fistula in ano are poorly understood.


METHODS
A consecutive series of 58 children (51 boys, seven girls) with a perianal abscess or fistula attending a tertiary referral centre over a 4-year period was reviewed.


RESULTS
Thirty-eight children (34 boys, four girls), ranging in age from 1 month to 12 years, presented with an abscess. After treatment, three developed a further abscess but only four developed a fistula. Fistula formation only occurred in those with enteric bacterial infection. Of 24 children with a perianal fistula five required further surgery for recurrence, four of whom were initially treated by fistulotomy. In most patients, the fistula was simple, low and direct, and treatment by fistulectomy resulted in significantly fewer recurrences. Apart from Crohn's disease, identifiable aetiological factors were rare.


CONCLUSIONS
Perianal sepsis is most common in otherwise healthy boys under 2 years of age. Abscess is best treated by incision and drainage, and fistulectomy is successful for the small proportion who develop a fistula.
