Rectal prolapse
Rectal prolapse

Rectal prolapse
Definition:
Rectal prolapse is the abnormal movement of the rectal mucosa down to or through the anal opening.

Causes, incidence, and risk factors:

When protruding through the anus, prolapse appears as a red mass that may be several inches long. The rectal mucosa is visible and may bleed slightly. Rectal prolapse occurs predominantly in children under age 6, and in the elderly.

Rectal prolapse is often associated with other conditions such as:
Symptoms:
The main symptom is a protrusion of a reddish mass from the anal opening, especially following a bowel movement.
Signs and tests:
See the individual conditions.
Treatment:

Call your health care provider if a rectal prolapse occurs. In some cases, the prolapse can be treated at home.

The rectal mucosa must be returned to the rectum manually. A soft, warm, wet cloth is used to apply gentle pressure to the mass to push it back through the anal opening. The affected person should be in a knee-chest position before applying pressure to allow gravity to help return the prolapse.

Immediate surgery for repair is seldom needed. The underlying condition must be treated.
Expectations (prognosis):

Treating the underlying condition usually cures the problem. In elderly patients with recurrent rectal prolapse who are good candidates for surgery, surgery can repair the anatomic problems that can predispose them to prolapse.
Complications:
Calling your health care provider:
Call your health care provider promptly if there is a rectal prolapse.
Prevention:
Treating the underlying condition usually prevents further rectal prolapse.
