Symptoms
The first sign of
rectal prolapse is often the unexpected release of
mucus, stool, or blood from the
anus.
Other symptoms of rectal prolapse include:
- A feeling of having full bowels and an urgent
need to have a bowel movement.
- Passage of many very small
stools.
- The feeling of not being able to empty the bowels
completely.
- An inability to control bowel movements (fecal incontinence) that becomes worse over
time.
- Anal pain, itching, irritation, and
bleeding.
- Bright red tissue that protrudes from the anus.
You may notice tissue slipping out of the anus during a bowel
movement. As the condition becomes worse, tissue may slide out of the anus when
you stand and then may remain outside the anus all the time.
Prolapse of only the lining of the
rectum (mucosal prolapse) can be confused with
hemorrhoids. In mucosal prolapse, rings of red tissue
usually protrude out of the anus while you strain during a bowel movement. In
hemorrhoids, the tissue that protrudes out of or next to the anus may look like
a red or blue lump, and there may be several lumps.
Complications
Rectal prolapse that is not treated can lead to
complications.
- Fecal incontinence may become worse, and
permanent damage can occur to the circular muscle that controls the anus (anal
sphincter).
- The rectum can become damaged from the tissues
rubbing together, which can result in a sore (ulcer) that may
bleed.
- Normal blood flow to tissue in the rectum may be cut off,
causing the tissue to die (gangrene).
- If a prolapsed rectum swells,
it may prevent the passage of stools.
- Rarely, a loop of the large
intestine is pinched off (strangulated), causing blockage of the intestine
(bowel obstruction).
Other conditions that can cause symptoms similar to those of rectal
prolapse include
inflammatory bowel disease,
irritable bowel syndrome,
polyps, and colon or rectal cancer. Complications
after surgery for
hemorrhoids or a
fistula also can cause these symptoms.
