Intussusception is when one part of the intestine slides up into another part of the intestine. This creates a blockage and makes it hard for the intestines to work as they should.

The cause of intussusception is not always known in most children. Rarely, it is triggered by a health problem, such as:
Intussusception is more common in children under 12 months of age. It is also more common in males. Other things that may raise the risk are:
- Having a health problem that can trigger intussusception
- Abdominal trauma or surgery
- Bacterial and parasitic infections
- Antibiotic use
- Rotavirus vaccine (uncommon)
- Severe belly pain that may cause a child to pull their knees up to their chest
- Vomiting, often yellow or green in color
- Stools mixed with mucus and blood
- Lack of alertness
The doctor will ask about the child's symptoms and past health. A physical exam will be done. This is often enough to make the diagnosis.
Pictures may be taken of the child's belly to confirm the diagnosis. This may be done with an ultrasound.
Intussusception is an emergency that must be treated right away to avoid severe problems. The goal of treatment is to unblock the intestine so that it can work the way it should. This may be done with:
- A small, soft tube in the rectum that delivers air or a solution with contrast material to unblock the intestine
- Surgery to release the trapped part of the intestine and remove any tissue damage
There are no current guidelines to prevent intussusception.
