Epidemiology

Foreign body ingestion and food impaction are common gastrointestinal (GI) problems. Fortunately, >80% of ingested foreign bodies pass through the GI tract without incident. However, sharp/pointed objects (e.g., razor blades, bones, pins, needles, wire, or nails) and objects >2.5 cm in diameter will not pass through the pyloric opening. Objects >6 cm long will not advance through the duodenal loop. High-powered magnets and batteries have also been implicated in complications and are difficult to remove.
