intussusception
Pronunciation: in-tə-sə-SEP-shən
Telescoping of one segment of bowel into an adjacent segment. Pediatric surgical emergency causing intestinal obstruction and potential bowel ischemia.
Full Definition
A condition where one segment of intestine slides into an adjacent segment, similar to a collapsing telescope, creating intestinal obstruction and compromising blood supply to the affected bowel. Most commonly occurs in infants and young children, typically involving the ileocolic region. Emergency treatment may include pneumatic or hydrostatic reduction, but surgical intervention is required when non-operative reduction fails or when signs of perforation or peritonitis are present.
Usage
Usage note: Plural form is 'intussusceptions'; avoid confusion with 'invagination' in formal reports.
