Final answer:
Intussusception is a folding of one segment of the intestine into another, often causing severe complications such as bowel obstruction and ischemia. It is marked by severe abdominal pain, 'currant jelly' stools, swelling, vomiting, and lethargy. Immediate medical treatment is essential.
Step-by-step explanation:
Intussusception is a medical condition in which a part of the intestine folds into the section next to it, somewhat like the pieces of a collapsible telescope. This most commonly occurs in infants and young children, and the causes can range from idiopathic (unknown) to specific triggers like intestinal polyps or viral infections.
The primary complication of intussusception is bowel obstruction, which can lead to impaired blood flow to the affected part of the intestine (ischemia), and if left untreated, can cause intestinal perforation, infection (peritonitis), and death.
Signs and symptoms
Prompt medical intervention is critical to resolve intussusception and avoid severe complications.
