What is an omphalocele?

An omphalocele is a birth defect. It happens when your baby is forming during pregnancy.

In this condition, some of your baby’s abdominal organs poke out (protrude) from the belly through the belly button (umbilicus). A clear (translucent) membrane covers the organs.

The omphalocele may be small. Only a part of the intestine may stick out. Or it may be large, with most of the abdominal organs being outside the abdomen. These can include the intestine, liver, and spleen.

Your baby’s abdominal cavity may also be too small. This is because it did not fully form in pregnancy.

What causes an omphalocele?

Healthcare providers don't know what causes this condition.

Your baby’s abdominal organs and muscles just don’t form like they should. Many babies born with this condition also have other health issues.

What are the symptoms of an omphalocele?

Your baby’s abdominal organs will poke out (protrude) from the belly through the belly button.

How is an omphalocele diagnosed?

Your baby’s healthcare provider may spot this issue on an ultrasound in the second or third trimester of pregnancy. Your baby may also need an ultrasound of the heart (fetal echocardiogram) before they are born. This test looks for heart problems.

After your baby is born, their healthcare provider will see the omphalocele during an exam. Your baby may also need an X-ray. This test is done to look for problems with other organs.

How is an omphalocele treated?

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how bad the condition is.

What are possible complications of an omphalocele?

If the protective membrane around your baby’s organs breaks, your baby could get an infection. Also, if an organ is pinched or twisted, it can lose its blood supply. This can harm the organ.

Living with an omphalocele

After surgery, your baby may still be at risk for long-term issues. Your baby’s chance for future problems depends on:

• The size of the omphalocele

• If part of the intestine or other organs lost blood flow

• Other health issues

Small omphaloceles normally cause no long-term problems.

Babies with damage to the abdominal organs may have long-term problems. Your child may have trouble with digestion,bowel movements, and infection.

Ask your child's healthcare provider about your child’s outlook. They will make a care plan for your baby. You may need to watch your baby’s nutrition, bowel function, and other aspects of your baby’s health.

When should I call my child's healthcare provider?

You’ll learn how to care for your baby once they leave the hospital. If you have any questions, call your baby’s healthcare provider.

If your child doesn’t gain weight or has trouble eating or having bowel movements, call your child’s healthcare provider.
