What is the “classic triad” of intussusception? Does it occur in most patients?
Intussusception occurs when a portion of the bowel, usually the distal ileum, telescopes into an adjacent segment of bowel. This effectively leads to intestinal obstruction followed by venous congestion and, finally, arterial insufficiency. The classic triad of pain, currant-jelly stool, and abdominal mass on palpation is present in only 20% to 25% of children with intussusception.
