title: Perirectal abscesses in six horses.
abstract: Perirectal abscesses were diagnosed retrospectively in 6 horses treated for colic. The abscesses caused colic in the horses by producing an extraluminal obstruction that led to fecal impaction. The abscesses were diagnosed by rectal palpation and aspiration of exudate from the masses and were drained surgically. In horses in which the abscess involved abdominal organs, peritonitis developed.
