Small bowel prolapse, also called enterocele (EN-tur-o-seel), occurs when the small intestine (small bowel) descends into the lower pelvic cavity and pushes at the top part of the vagina, creating a bulge. The word "prolapse" means to slip or fall out of place.
In women who have had surgery to remove the uterus (hysterectomy), small bowel prolapse is also called apical prolapse or vaginal vault prolapse and may involve the bladder or rectum as well as the small bowel.
Childbirth, aging and other processes that put pressure on your pelvic floor may weaken the muscles and ligaments that support pelvic organs, making small bowel prolapse more likely to occur.
To manage small bowel prolapse, self-care measures and other nonsurgical options are often effective. In severe cases, you may need surgical repair.
Mild small bowel prolapse may produce no signs or symptoms. However, if you have significant prolapse, you might experience:
- A pulling sensation in your pelvis that eases when you lie down
- A feeling of pelvic fullness, pressure or pain
- Low back pain that eases when you lie down
- A soft bulge of tissue in your vagina
- Vaginal discomfort and painful intercourse (dyspareunia)
Many women with small bowel prolapse also have related conditions, such as:
- Posterior prolapse, also known as rectocele, when the bottom or back of the vagina bulges, often because the rectum pushes on the vaginal wall
- Anterior prolapse, also known as cystocele, when the front of the vagina is pushed down — usually by the bladder — into the vaginal canal
- Uterine prolapse, when the uterus pushes down into the vagina
When to see a doctor
See your doctor if you develop signs or symptoms of prolapse that bother you.
Increased pressure on the pelvic floor is the main reason for any form of pelvic organ prolapse. Conditions and activities that can cause or contribute to small bowel prolapse or other types of prolapse include:
- Pregnancy and childbirth
- Chronic constipation or straining with bowel movements
- Chronic cough or bronchitis
- Repeated heavy lifting
- Being overweight or obese
Pregnancy and childbirth
Pregnancy and childbirth are the most common causes of pelvic organ prolapse. The muscles, ligaments and fascia that hold and support your vagina stretch and weaken during pregnancy, labor and delivery. Not everyone who has had a baby develops pelvic organ prolapse. Some women have very strong supporting muscles, ligaments and fascia in the pelvis and never have a problem.
Factors that increase your risk of developing small bowel prolapse include:
- Pregnancy and childbirth. Vaginal delivery of one or more children contributes to the weakening of your pelvic floor support structures, increasing your risk of prolapse. The more pregnancies you have, the greater your risk of developing any type of pelvic organ prolapse. Women who have only cesarean deliveries are less likely to develop prolapse.
- Age. Small bowel prolapse and other types of pelvic organ prolapse occur more often with increasing age. As you get older, you tend to lose muscle mass and muscle strength — in your pelvic muscles as well as other muscles.
- Pelvic surgery. Removal of your uterus (hysterectomy) or surgical procedures to treat incontinence may increase your risk of developing small bowel prolapse.
- Increased abdominal pressure. Being overweight increases pressure inside your abdomen, which increases your risk of developing small bowel prolapse. Other factors that increase pressure include ongoing (chronic) cough and straining during bowel movements.
- Smoking. Smoking is associated with developing prolapse because smokers frequently cough, increasing abdominal pressure. Also, smokers may have problems with healing of damaged connective tissues in the pelvic area, which can contribute to prolapse.
- Race. For unknown reasons, Hispanic and Caucasian women are at higher risk of developing pelvic organ prolapse. Black women seem to have the lowest risk of all groups of women.
- Family history. If your mother experienced small bowel prolapse or prolapse of other pelvic organs, your chances of having prolapse are greater than that of a woman with no family history of prolapse.
- Connective tissue disorders. You may be genetically prone to prolapse due to weaker connective tissues in your pelvic area, making you naturally more susceptible to small bowel prolapse and other types of pelvic organ prolapse.
Preparing for your appointment
Your first appointment may be with your primary care provider or with a doctor who specializes in conditions affecting the female reproductive tract (gynecologist) or the reproductive tract and urinary system (urogynecologist, urologist).
What you can do
Here's some information to help you prepare for your appointment.
- Make a list of any symptoms you've had, and for how long.
- List your key medical information, including other conditions for which you're being treated and any medications, vitamins or supplements you're taking.
- Take a family member or friend along, if possible, to help you remember all the information you'll receive.
- List questions to ask your doctor, putting them in order of importance, in case time runs out.
For small bowel prolapse, basic questions to ask your doctor include:
- Is the prolapse causing my symptoms?
- What are the goals of treatment in my case?
- What treatment approaches do you recommend?
- What is the risk of treating the prolapse compared with not treating the prolapse?
- What is the risk that this problem will recur at any time in the future?
- Do I need to follow any restrictions to prevent progression?
- Are there any self-care steps I can take?
- Should I see a specialist?
Don't hesitate to ask questions during your appointment if you don't understand something.
What to expect from your doctor
Your doctor may ask questions such as:
- What symptoms do you have?
- When did you first notice these symptoms?
- Have your symptoms gotten worse over time?
- Do you have pelvic pain? If yes, how severe is the pain?
- Does anything seem to trigger your symptoms, such as coughing or heavy lifting?
- Do you have urine leakage (urinary incontinence)?
- Have you had an ongoing (chronic) or severe cough?
- Is heavy lifting involved in your work or daily activities?
- Do you strain during bowel movements?
- Do you have any other medical conditions?
- What medications, vitamins or supplements do you take?
- Have you been pregnant and had vaginal deliveries?
- Do you wish to have children in the future?
Tests and diagnosis
Your doctor performs a pelvic exam to confirm a diagnosis of small bowel prolapse. During the exam, your doctor may ask you to take a deep breath and hold it while bearing down (Valsalva maneuver), which is likely to cause the prolapsed small bowel to bulge downward. If your doctor can't verify that you have a prolapse while you're lying on the exam table, he or she may repeat the exam while you're standing.
Treatments and drugs
Mild and moderate cases of small bowel prolapse typically do not need treatment. Surgery may be effective for more significant cases of symptom-causing prolapse. Nonsurgical approaches are available if you're not interested in surgery, if surgery would be too risky or if you want to become pregnant in the future.
Treatment options for small bowel prolapse include:
- Observation. If your prolapse causes few or no obvious symptoms, you don't need treatment. Simple self-care measures, such as performing exercises called Kegels to strengthen your pelvic muscles, may provide symptom relief. Avoiding heavy lifting and constipation may reduce the likelihood of worsening your prolapse.
- Pessary. A silicone, plastic or rubber device inserted into your vagina supports the bulging tissue. Pessaries come in a variety of styles and sizes. Finding the right one for you may involve trial and error. Your doctor will measure and fit you for the device, and you'll learn how to insert, remove and clean it.
Surgery. Your surgeon can perform surgery to repair the prolapse through the vagina or abdomen, with or without the use of a robot. During the procedure, your surgeon moves the prolapsed small bowel back into place and tightens the connective tissue of your pelvic floor. Sometimes, small portions of synthetic mesh may be used to help support weakened tissues. Larger pieces of mesh are associated with mesh erosion and generally aren't recommended.
A small bowel prolapse usually doesn't recur. However, further injury to the pelvic floor can happen with increased pelvic pressure, for instance with constipation, coughing, obesity or heavy lifting.
Lifestyle and home remedies
Depending on the severity of your condition, self-care measures may provide the relief you need:
- Perform Kegel exercises to strengthen pelvic muscles and support weakened vaginal tissues.
- Avoid constipation by drinking plenty of fluids and eating high-fiber foods, such as whole grains, and fresh fruits and vegetables.
- Avoid heavy lifting.
- Try to control coughing.
- Lose weight if you're overweight or obese.
- Avoid bearing down to move your bowels. Rely on your natural colorectal function to empty your lower bowel.
Kegel exercises strengthen your pelvic floor muscles, which, in part, support the uterus, bladder and bowel. A strong pelvic floor provides better support for your pelvic organs, prevents prolapse from worsening and relieves symptoms associated with pelvic organ prolapse.
To perform Kegel exercises, follow these steps:
- Tighten (contract) your pelvic floor muscles — the muscles you use to stop urinating.
- Hold the contraction for five seconds, then relax for five seconds. (If this is too difficult, start by holding for two seconds and relaxing for three seconds.)
- Work up to holding the contraction for 10 seconds at a time.
- Aim for at least three sets of 10 repetitions each day.
Ask your health care provider for feedback on whether you're using the right muscles. Kegel exercises may be most successful when they're taught by a physical therapist and reinforced with biofeedback. Biofeedback involves using monitoring devices that help ensure you're tightening the proper muscles, with optimal intensity and length of time.
Once you've learned the proper method, you can do Kegel exercises discreetly just about anytime, whether you're sitting at your desk or relaxing on the couch.
You may be able to lower your chances of small bowel prolapse with these strategies:
- Maintain a healthy weight. If you're overweight, losing some weight can decrease the pressure inside your abdomen.
- Prevent constipation. Eat high-fiber foods, drink plenty of fluids and exercise regularly to help prevent having to strain during bowel movements.
- Treat a chronic cough. Constant coughing increases abdominal pressure. See your doctor to ask about treatment if you have an ongoing (chronic) cough.
- Quit smoking. Smoking contributes to chronic coughing.
- Avoid heavy lifting. Lifting heavy objects increases abdominal pressure.
