Intestinal malrotation is a birth defect. It happens when your baby’s intestinal tract doesn’t form as it should during pregnancy. Malrotation happens when your baby’s intestine doesn’t turn like it should.
This can cause a problem called a volvulus after you baby is born. In this condition, your baby’s intestine gets twisted. This can cause an intestinal blockage. It also cuts of blood flow to the intestine. This can damage your baby’s intestine.
Most children with this condition have symptoms within the first year of life. Some people who have malrotation go their whole life without having any symptoms and are never diagnosed. Other people may not have symptoms until adolescence or adulthood.
Malrotation happens in the early stages of pregnancy when your baby’s intestines don’t form the right away. Healthcare providers don't know why this happens.
A volvulus is caused by the malrotation. It causes the small intestine to twist around the superior mesenteric artery. Not everyone who is born with a malrotation will develop a volvulus.
Malrotation happens equally in boys and girls. But more boys have symptoms by the first month of life than girls.
Babies with other health issues have a greater risk of having a malrotation. These problems include diaphragmatic hernia, omphalocele, and duodenal atresia.
Symptoms can happen a bit differently in each child. They can include:
The symptoms of malrotation may look like other health problems. Your child’s healthcare provider must diagnose him or her with this condition.
Your child's healthcare provider will ask about your child's health history. He or she will also give your child an exam.
Your child may also need tests that show pictures of the inside of his or her body (imaging studies). These tests will show the position of your child’s intestine, and whether it’s twisted or blocked.
Your child may have blood tests to check electrolytes.
Your child may have a test to look for blood in stool samples.
A CT scan shows detailed images of any part of the body. This test will show your child’s bones, muscles, fat, and organs. CT scans are more detailed than general X-rays.
This test can show if your child has intestinal blockages.
This test looks at the organs in the upper part of your child’s digestive system. For this test, your child will swallow barium. This is a metallic liquid that coats the inside of his or her organs. This helps them show up on an X-ray better. Then your child’s healthcare provider will take an X-ray of these organs. It can show an abnormal location for the small intestine, blockages, and other problems.
This test looks at the large intestine. The healthcare provider will put barium into your child's rectum as an enema. The provider will take X-rays of the belly. This can show that your child’s large intestine isn’t where it should be.
This test is done to check for volvulus. It looks at the lower part of your child’s gastrointestinal (GI) tract, rectum, and colon.
Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how severe the condition is.
A volvulus is a life-threatening problem. This is because the intestine can die when it’s twisted and doesn’t have enough blood supply.
Your child may need IV (intravenous) fluids to prevent dehydration. He or she may also need antibiotic medicine to prevent an infection. Your child may also need an NG (nasogastric) tube. This tube may be guided from your child’s nose, through the throat and esophagus, to the stomach. This can keep gas from building up.
A child with a volvulus needs surgery as soon as possible. Your child’s surgeon will untwist the intestine. He or she will also check it for damage. Your child’s intestine will turn pink after it’s unwound and circulation comes back.
If your child’s intestine is healthy, it will be put back into your child’s belly. This will move the location of your child’s appendix. This can make it hard for healthcare providers to diagnose appendix problems in the future. Because of this risk, your child’s appendix will also likely be taken out at this time.
If your child’s healthcare provider isn’t sure about the blood supply to the intestine, your child’s intestine may be untwisted and put back into your child’s belly. Your child will have another surgery 24 to 48 hours later. If the intestine has been damaged, the injured section will be removed.
If the injured section of intestine is large, a big part of the intestine may be taken out. In this case, your child will need a colostomy for his or her digestive system to work as it should.
In a colostomy, the two healthy ends of intestine are brought through openings in the belly. Stool will pass through the opening (stoma) and then into a collection bag. The colostomy may be temporary or permanent. This depends on the amount of intestine that was removed.
Volvulus can cause a blockage in your child’s intestine. This can keep food from being digested well. This can also cause blood supply to the twisted part of the intestine to be cut off. This can lead to the death of that part of the intestine.
Malrotation can also cause Ladd's bands. These form between the cecum and the intestinal wall. This can also form a blockage and keep food from being digested.
A child can become dehydrated quickly when an intestinal blockage happens.
Most children who have a volvulus fixed with surgery often have no long-term problems if there wasn’t any intestinal damage.
Children with intestinal injury who had the damaged part removed may have long-term problems. Taking out a large part of the intestine can affect digestion. This can keep your child from getting enough foods and liquids. You should offer your child food and liquids often to make sure he or she is getting enough nutrients.
