The picture shows a condition in which one segment of the bowel mostly proximal (intussusceptum), invaginates into the adjacent distal segment (intussuscipiens). Children are commonly affected with a peak incidence between 5 to 10 months of age. Most cases are idiopathic but an association with gastroenteritis has been seen in some cases. Ileocolic is the most common variety found in children. Intussusception is relatively uncommon in adults and usually presents secondary to intestinal pathology i.e. polyp, Meckel's diverticulum. If not treated timely the blood supply can be compromised leading to a number of complications. The most feared complication is necrosis and bowel perforation from strangulated intussusception.
