The most important factors in determining symptoms at presentation, as well as management, are location within the GI tract and duration of contact with the mucosal surface. Batteries that are lodged in the esophagus may be asymptomatic initially or can present with pain, drooling, dysphagia, poor oral intake, cough, vomiting, or fever. Mechanisms of injury associated with button battery ingestion include liquefactive necrosis resulting from alkali exposure due to battery leakage or the de novo synthesis of alkali at the surface of the battery, electrical current–induced soft-tissue injury, and tissue pressure necrosis.
