Severe gastric damage caused by button battery ingestion in a 3-month-old infant

Ingestion of a button battery has been considered a serious problem, causing necrosis and perforation, when impacted in the esophagus. However, such batteries in the stomach rarely cause any harm to the gastric wall, which is regarded as evidence supporting the use of conservative treatment. We present the rare case of a 3-month-old infant with severe gastric wall injury caused by a button battery lodged in the stomach. The present case suggests that button batteries located in the stomach should be removed as soon as possible, especially in infants.
