Abstract
A prospective survey of patients with anorectal abscesses treated at Cook County Hospital [Chicago, Illinois, USA] over a 35 mo. period produced data on 474 patients. The peak incidence was in the 3rd decade of life. Males were affected 1.76 times more frequently than females. Perianal abscess was the most common anatomic type (42%), with ischiorectal abscess (20%) being 2nd. The supralevator space was involved in 7% of the abscesses. Primary fistulotomy was performed when an anal fistual could be demonstrated (34%). A standardized method of treatment, utilizing radical incisions for drainage, produced satisfactory results with a complication rate of 3%, an in-hospital reoperation rate of 0.6% and an average hospital stay of 5.7 days.
