A Meckel’s diverticulum is a small pouch of tissue on the bowel (intestine). It forms when a baby is still growing in the womb. A Meckel’s diverticulum may bleed. It may also become infected. Or the intestine can twist around it. When these occur, the Meckel’s diverticulum must be removed.
Many children with a Meckel’s diverticulum never have symptoms. When a problem does occur, it’s often around age 2. The most common signs of a problem include:
Blood in stool
Low levels of red blood cells (anemia) due to blood loss that can cause low energy and pale skin
Signs of infection such as fever, chills, or pain in the abdomen
Signs of intestinal blockage such as nausea, vomiting, pain
It’s common for the problem to not be found unless it causes symptoms. If your child has symptoms, he or she may have tests such as:
Blood tests. These check for signs of bleeding or infection.
Stool sample. This may be done to check for blood.
Meckel’s scan. A special dye is injected into the child’s bloodstream through an intravenous (IV) line. This dye may make the Meckel’s tissue show up on a scan.
Ultrasound. This test uses sound waves to make images. In some cases, the problem can be seen on an ultrasound image.
Arteriogram. This is a special X-ray test. Dye is injected into the arteries to see if bleeding can be seen. This may be done if bleeding is severe and the source can't be found.
Other tests. Imaging tests such as an X-ray or CT scan may be done to rule out other problems.
If the child has no symptoms, treatment may not be needed. But if it’s causing symptoms, it will likely be removed with surgery. After surgery, the symptoms will go away.
