Although the battery was extracted from the upper esophagus a mere 2 hours after its ingestion, it had already corroded and had begun to erode the esophageal wall.
The toddler was admitted for observation. Augmentin and Zantac were administered. After proving asymptomatic for 2 days, he was discharged.

Button/coin/disk batteries lodged in the esophagus must be retrieved immediately, as the mucosa can close a curcuit, resulting in an electrical burn or even perforation. Older batteries contained toxic metals, such as mercury or cadmium, for which a chelating agent was given if they leaked.
