Rectal prolapse occurs when the rectum descends (falls and comes through) the anal opening.
Rectal prolapse occurs most often in children under age 6 and in the elderly.
In children, it can be found with cystic fibrosis, worm infections of the intestine, or long-term diarrhea.
In adults, it is usually found with constipation, or with a muscle or nerve problem in the pelvic or genital area.
The main symptom is a reddish-colored mass that sticks out from the opening of the anus, especially after a bowel movement. This reddish mass is actually the inner lining of the rectum. It may bleed slightly and can be uncomfortable and painful.
The health care provider will perform a physical exam, which will include a rectal exam. Tests can determine the cause.
Call your health care provider if a rectal prolapse occurs. In some cases, the prolapse can be treated at home.
The rectum must be pushed back inside manually. A soft, warm, wet cloth is used to apply gentle pressure to the mass to push it back through the anal opening. The person should lie on one side in a knee-chest position before applying pressure. This position allows gravity to help put the rectum back into position.
Immediate surgery is rarely needed. In children, treating the cause usually solves the problem. In adults, the only cure for rectal prolapse is a procedure that repairs the weakened anal sphincter and pelvic muscles.
In children, treating the cause usually cures rectal prolapse. In adults, surgery is usually cures the prolapse.
When rectal prolapse is not treated, constipation and loss of bowel control may develop.
Call your health care provider promptly if there is a rectal prolapse.
In children, treating the cause usually prevents rectal prolapse from happening again.
