Intussusception in children refers to a condition in which a part of intestine telescopes into an adjacent part of intestine. This movement blocks food and fluid from passing through the intestine as it should, and if left untreated, can lead to damage of the bowel. The lack of blood flow to the bowel can result in significant damage and even perforation. Patients typically will present with colicky abdominal pain and bloody, mucoid stool. Treatment is aimed at pushing the intestines back into the correct position using either an air enema or surgery where necessary.
