Abstract
A total of 383 infants with anal fistula (perirectal abscess) were studied. This disease was frequently seen in infants less than six months of age, usually started as a perianal abscess, then getting to form subcutaneous fistula to direct lateraly. Three or more lesions located in the median sites often occurred at the lower age group. The incidence of a single lesion tended to increase when patients aged one year or more, where lateral lesions were less frequent. Diseases with early onset at lower age and the presence of multiple lesions were factors to prolong treatment, The out-patient compression method seems to be the treatment of choice when self-limited condition and patients' burden are taken into account.
