Intussusception
Pronunciation: in-tuh-suh-SEP-shuhn
Telescoping of one bowel segment into another, causing intestinal obstruction and potential ischemia.
Full Definition
Intussusception occurs when a proximal segment of bowel invaginates into a distal segment, most commonly at the ileocolic junction in infants. It presents with intermittent severe abdominal pain, vomiting, and the classic 'currant jelly' stools containing blood and mucus. The condition can be precipitated by viral infections, particularly adenovirus and rotavirus, which cause lymphoid hyperplasia. Prompt recognition and treatment with pneumatic or hydrostatic reduction is essential to prevent bowel necrosis.
Usage
Usage note: Often follows viral gastroenteritis in pediatric patients.
