Intussusceptions

Intussusception is the most common cause of intestinal obstruction in infants and children aged 3 months to 6 years and is the second most common cause of acute abdomen in this age group. It occurs when a proximal segment of the intestine (called intussusceptum) telescopes or invaginates into the lumen of another immediately adjacent distal segment (called intussuscipiens). The peak age of presentation is between 5 and 10 months. Intussusception is more common in males. Less than 1% of intussusceptions are found in neonates; however, cases have been reported in newborns and premature babies. Early diagnosis and prompt treatment prevent catastrophic complications in this group of patients. In 95% of cases, the intussusception is in the ileocecal area. Ileoileal and colocolic intussusceptions are rare. Occasionally, an ileoileal intussusception of the terminal ileum may progress through the ileocecal valve, a condition known as ileoileocolic intussusception
