title: Corrosive tracheo-esophageal fistula following button battery ingestion.
abstract: We describe a case of corrosive tracheo-esophageal fistula following button battery ingestion in a 1-year old nonverbal pediatric patient. The delay in diagnosis was caused by failure to obtain correct history and failure to detect opacity of the battery in the neck at the first visit.  The large fistula was successfully treated with division and repair with non absorbable sutures, with interposition of strap muscles between separated trachea and esophagus.
