Anorectal abscess   

Overview | Symptoms | Treatment | Prevention

Alternative names:

Anal abscess; Rectal abscess; Abscess - anorectal

Definition:

A collection of pus in the anal or rectal region.

Causes and Risks

Infection of an anal fissure (cleft or slit), sexually transmitted infections, and blocked anal glands are causes of anorectal abscesses. Abscesses may occur in an area that is easily accessible for drainage, or higher in the rectum. Deep rectal abscesses may be caused by intestinal disorders such as Crohn's disease or diverticulitis.

Superficial perianal abscesses are not uncommon in infants and toddlers who are still in diapers and have a history of anal fissures. The abscess often appears as a swollen, red, tender lump at the edge of the anus. The infant may be fussy from discomfort but there are generally no other associated systemic symptoms. Surgical drainage and antibiotics provide prompt relief.
