Button battery ingestion: The battery that is not as cute as a button

Abstract

Button batteries lodged in the mucosal tract cause caustic injury, mucosal ulceration, and, if impacted long enough, perforation. The esophagus is the most common site for impaction. The severity of esophageal damage is determined by the length of time that the battery is lodged in place, the amount of electrical charge remaining in the battery, and the size of the battery.
