Esophageal lesions following button-battery ingestion in children: Analysis of causes and proposals for preventive measures

Esophageal lesions due to ingestion of button-batteries in children are almost always due to batteries larger than 20 mm in diameter, mostly from devices with a poorly protected compartment, or batteries that are not individually packaged. These lesions cause serious complications in a quarter of cases and their management entails high health costs. Legislation requiring screw-secured compartments and individual blisters for batteries could have prevented 69.2% of the ingestions.
