Supralevator abscess: diagnosis and treatment

Abstract

Anorectal suppurations are quite common. Supralevator abscesses, previously regarded as a rare subgroup, were seen in 9.1 per cent of 506 patients admitted to Cook County Hospital in a two-year period. Aggressive supportive management was followed by early, adequate drainage through the rectum whenever indicated. When fistulas were identified, either a primary fistulotomy or a two-stage fistulotomy using a seton was performed in the majority of cases. Important factors in the prevention of morbidity and mortality included debridement of all necrotic tissue, careful bacteriologic studies and judicious use of antibiotics, close postoperative observation, and long-term follow-up of the patients.
