intussusception
Pronunciation: in-tuh-suh-SEP-shun
Telescoping of one segment of intestine into another, creating a surgical emergency most common in infants and toddlers.
Full Definition
Intussusception is a condition where one portion of the intestine slides into an adjacent section, similar to a telescope collapsing. It is the most common cause of intestinal obstruction in children between 6 months and 3 years of age, with peak incidence around 5-9 months. The classic presentation includes intermittent abdominal pain, vomiting, and bloody stools (often described as 'currant jelly' stool), though this complete triad is present in only a minority of cases. Diagnosis is often made by ultrasound or CT scan, and treatment may involve pneumatic or hydrostatic reduction, though surgical intervention may be necessary if reduction fails or complications arise.
Usage
Usage note: Note the double 's' in the middle of the word; commonly misspelled.
