Intussusception is a process in which a segment of intestine invaginates into the adjoining intestinal lumen, causing bowel obstruction. Intussusception presents in two variants: idiopathic intussusception, which usually starts at the ileocolic junction and affects infants and toddlers; and enteroenteral intussusception (jejunojejunal, jejunoileal, ileoileal), which occurs in older children. The latter is associated with special medical situations (eg, Henoch-Schönlein purpura, cystic fibrosis, hematologic dyscrasias) or may be secondary to a lead point (polyps or terminal ileum lymph node hyperplasia); occasionally it occurs in the postoperative period (after extensive retroperitoneal dissections).
