Intussusception is a condition in which part of the intestine (usually the lower part of the small intestine) folds inward and into itself, like a telescope. It can cause swelling, pain, and a complete or partial loss of blood supply to the affected area. If not treated, the affected intestine may burst or die, causing a serious, life-threatening condition. Intussusception is most common in children.
