A form of intestinal obstruction caused by the PROLAPSE of a part of the intestine into the adjoining intestinal lumen. There are four types: colic, involving segments of the LARGE INTESTINE; enteric, involving only the SMALL INTESTINE; ileocecal, in which the ILEOCECAL VALVE prolapses into the CECUM, drawing the ILEUM along with it; and ileocolic, in which the ileum prolapses through the ileocecal valve into the COLON.

An abnormality of the intestine in which part of the intestine invaginates (telescopes) into another part of the intestine.

Telescoping or invagination of a part of the intestine into an adjacent segment.

Intussusception is telescoping of one portion of the intestine (intussusceptum) into an adjacent segment (intussuscipiens), causing intestinal obstruction and sometimes intestinal ischemia. Diagnosis is by ultrasonography. Treatment is with an air enema and sometimes surgery.

Intussusception (see the image below) is a process in which a segment of intestine invaginates into the adjoining intestinal lumen, causing bowel obstruction. With early diagnosis, appropriate fluid resuscitation, and therapy, the mortality rate from intussusception in children is less than 1%.

Intussusception (in-tuh-suh-SEP-shun) is a serious condition in which part of the intestine slides into an adjacent part of the intestine. This "telescoping" often blocks food or fluid from passing through. Intussusception also cuts off the blood supply to the part of the intestine that's affected, which can lead to a tear in the bowel...

Intussusception is a common cause of intestinal obstruction in young children and is defined as the prolapse of one part of intestine into the lumen of an adjoining distal part. This condition most often occurs in the ileocecal region. The lead point of the intussusception is most often an enlarged lymph node (Peyers patch) in the...
