Button battery induced traumatic tracheoesophageal fistula: Case report and review of literature.

Although accidental ingestions by children of various household chemicals and medicines are well described and the treatment is supported by protocols and hotlines, the ingestion of button batteries is less publicized, and the dangers are less understood by both parents and health care providers. We describe the case of a three-year-old girl, who presented to hospital with respiratory distress, cough, and fever; three weeks after the ingestion of a button battery. Endoscopic examination revealed impacted 20 mm disc battery, which was removed, and a tracheoesophageal fistula (TOF) in the upper third of the oesophagus associated with severe oesophagitis, and oesophageal ulcers.
