A Meckel diverticulum (also called a Meckel’s diverticulum) is a small pouch in the lining of the small intestine. Some babies have it at birth. The diverticulum doesn’t usually cause symptoms, so most people don’t know they have it.
Meckel diverticulum doesn’t cause symptoms in most people who have it. However, sometimes a child has symptoms such as:
Stools that look bright red, rust, purple, or black because of a bleeding diverticulum—this is most common in children under age 5
Sometimes, severe belly pain, belly tenderness, and throwing up if the diverticulum gets infected or inflamed—this is called diverticulitis
If doctors suspect your child has a Meckel diverticulum, they may do tests such as:
A Meckel scan, where doctors will give your child a tiny bit of a harmless radioactive substance through a vein and take pictures of the small intestine with a special camera
Video capsule endoscopy, where your child swallows a tiny camera that takes pictures as it passes through the digestive tract, including the intestines
Endoscopy, where doctors place a small flexible viewing tube up your child’s anus (the opening in your buttocks where stool comes out) to see the small intestine
