Up to 75% of cases occur in children under the age of 12 months.[10][13] Patients should be assessed first with a complete history and physical examination with a focus on the nature of abdominal pain (colicky versus constant), the presence of redcurrant jelly stools, and the presence or absence of vomiting. Almost all infants with intussusception present with abdominal pain and vomiting. The classic symptom of redcurrant jelly stool or rectal bleeding is present in 35% to 73% of cases.[5][10][13] Progressive lethargy is often associated, and patients may have a history of a recent viral illness.[5]
