title: Colonic fistulas.
abstract: Colonic fistulas are uncommon. They are frequently external but also occur internally to a number of organs. External fistulas are usually caused by a complication or are the result of a surgical procedure, such as leaking anastomosis or incision and drainage of an abscess resulting from an underlying pathologic condition.
