intussusception
Pronunciation: in-tus-suh-SEP-shun
Telescoping of one portion of intestine into an adjacent section, causing obstruction and requiring urgent intervention.
Full Definition
Intussusception occurs when one segment of intestine slides into an adjacent portion, similar to a telescope collapsing. This condition is most common in infants and young children between 6 months and 2 years of age. The telescoping action creates intestinal obstruction and compromises blood supply to the affected bowel segment. Classic symptoms include intermittent abdominal pain, vomiting, and bloody stools (currant jelly appearance). Emergency treatment typically involves pneumatic or hydrostatic reduction under fluoroscopic guidance, though surgical intervention may be necessary if reduction fails or complications develop.
Usage
Usage note: Often misspelled as 'intussuception' - note the double 's' in the correct spelling.
