title: Conservative management of fistula in ano in infants.
abstract: We analyzed the natural course of fistula in ano (FIA) and/or perianal abscess (PAA) in 97 children (male: 90, female: 7) and recommend conservative management in infants. Nearly one-half of these children had no recurrent episodes, and 80% of the infants recovered spontaneously within their 1st year of life. A radical operation was required in only 6 children after 2 years of age. Two-thirds of the children with a PAA did not develop fistula. Of the children who developed FIA, 42% had no recurrence. Although the duration of FIA was relatively longer than that of PAA, 55% of the children were cured within 1 year. PAA and/or FIA in infants is likely to be a period-limited disorder that occurs mainly in infancy and spontaneously resolves within 1 year of life. Fistulotomy or fistulectomy should be avoided in infants.
