Case Reports: Children with tracheoesophageal Fistula after Button Battery Ingestion

Button battery ingestions in children increased in recent years and may lead to life-threatening complications, especially if the battery is impacted in the esophagus. The pH close to the negative pole of the battery can rise in a very alkalotic range (pH > 10) leading to severe tissue damage. Therefore, in this case series report, the clinical courses of four children with button battery ingestion leading to tracheoesophageal fistulas are presented. The diagnosis and removal of the button battery was delayed in all cases. The surgical reconstruction of the trachea was performed in intravenous anesthesia and with extended monitoring. The intraoperative oxygenation was maintained using a combination of extracorporeal membrane oxygenation (ECMO) and mechanical ventilation via an endobronchial tube. To prevent these life-threatening complications, the awareness of the parents and child care providers should be raised, and the manufacturers should redesign their products to secure the battery compartment. In children with suspected battery ingestions, the immediate localization and removal of the battery (< 2 h) is of highest importance. Local administration of honey or sucralfate can be considered in ingestions < 12 h but should not delay an endoscopic removal.
