Abstract:
Disc batteries as foreign bodies present challenges in both diagnosis and management and carry a high risk for complications. We describe a novel device for disc battery removal using a magnet and basic medical supplies readily available in the emergency department setting. We also review diagnosis, complications, and management recommendations for disc batteries as foreign bodies.
