Pediatric esophageal foreign bodies (FBs) that involve disc batteries are increasingly common. Emergent retrieval may minimize potentially avoidable morbidities, such as esophageal perforation, tracheoesophageal fistula, and death. Management strategies for removal of pediatric esophageal batteries differ from those for retrieval of coins, for example, where serial imaging during a period of observation may be appropriate. Emergency physicians who also practice FB retrieval or advancement in the emergency department setting must be certain that the object is not a disc battery.
