Although most ingested foreign bodies in children pass spontaneously, certain foreign bodies can be harmful and they require special attention and emergent medical intervention to prevent significant morbidity and mortality. This article presents an overview of the epidemiology, diagnosis, management, and complications of foreign body ingestions in children. Particular attention is paid to coins, sharp objects, long objects, food bolus, caustic liquids, batteries, and magnets.
Key points
- •
Foreign body ingestions are common in children, especially children younger than 5 years.
- •
Foreign bodies should be evaluated by radiograph so that high-risk foreign bodies are not misdiagnosed.
- •
Coins are the most commonly retained foreign body in children and may be managed conservatively in otherwise healthy, asymptomatic patients.
- •
Button batteries, high-powered magnets, sharp objects, and caustic liquids carry the risk of serious clinical complications and should be evaluated and managed urgently.
