Foreign body ingestion in children: beware of disk batteries and multiple magnets.

Foreign body ingestion in children is a challenging clinical scenario. Children may be completely asymptomatic or present with overt symptoms, including drooling, dysphagia, chest pain, and feeding refusal (1, 2, 3). The majority of ingested foreign bodies passes spontaneously along the gastrointestinal (GI) tract and causes no harm nor symptoms.
