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