Button Battery Ingestions cause the Majority of Severe Complications

Abstract

Abstract Background Foreign body ingestion in children is a clinically important reason for presentation to the emergency department. The individual outcome ranges from benign spontaneous courses to severe complications. Fatal outcomes occur rarely and complications are related to patient’s age as well as type and location of the foreign body. The aim of our present study was to evaluate the outcome of children and adolescents with foreign body ingestion with a focus on complications, which mainly occurred after button battery ingestion. Methods We reviewed medical records of patients between 0 and 18 years of age who had presented to the paediatric emergency department of our hospital with suspected foreign body ingestion between January 2011 and March 2021 (123 months). Clinical, imaging, and endoscopic data as well as treatment modalities were analysed. Results In the ten10 year period under review, a total of 1,162 children and adolescents (6 months – 18 years) presented to our emergency room with suspected foreign body ingestion. Among those, 398 ingestions (34%) could be verified radiologically and/or endoscopically, while in the remaining 764 cases (66%) the suspicion could not be confirmed. The majority of patients with verified ingestion (n=324; 81%) presented with ingestion of a metallic foreign body. We observed 55 cases with verified ingestion of a button battery. Five of these cases had severe complications, with a near-fatal course in two patients who developed an oesophageal-tracheal fistula. Conclusion In contrast to all other ingestions of foreign bodies in children, button battery ingestions lead to mucosal damage and severe complications in a significant number of children.
