Ingested Button Battery Retrieved by a Modified Magnet Endoscope

Ingestion of button battery (BB) by toddlers has been seen with increasing frequency over the past decade. Significant morbidity may develop if the ingested BB cannot be removed in time. Herein, we describe 2 infants whose ingested BBs were smoothly and successfully retrieved, from a stenotic esophagus and stomach, by the use of a self-made modified magnet endoscope.
