Anorectal abscesses in immunosuppressed patients.

The results of surgery in 14 immunosuppressed patients with 17 anorectal abscesses are presented. Abscess incision was followed by almost immediate relief of pain. Healing was obtained in 15 cases, but two patients died of causes unrelated to surgery. Symptoms, therapeutic possibilities and prognosis are discussed. The authors conclude that surgery should be performed in all cases to prevent development of septicemia. Fluctuation should not be awaited, but surgery should be minimized if granulocyte and platelet counts are low. Each patient must be managed individually, according to the nature of malignant disease, general state of health and degree of immunosuppression. Antibiotic cover is important, and primary closure of the abscess cavity should never be attempted.
