A 9-month-old has episodes of intense crying drawing his legs to his abdomen, and is quiet and lethargic between episodes. He has vomited several times, and the nappy contains stool mixed with blood and mucus like jelly. T 37.5 °C, HR 160. What is the likely condition?

1. Intussusception
2. Hypertrophic pyloric stenosis
3. Normal infant colic
4. Viral gastroenteritis

Answer: A) Intussusception. Intermittent colicky pain with drawn-up legs, lethargy between episodes, vomiting and redcurrant-jelly stool indicate intussusception, commonest at 6–36 months. Diagnose by ultrasound; usually reduced by air or contrast enema.
