Acquired tracheo-esophageal fistulas caused by button battery lodged in the esophagus.

摘要

Esophageal impacting of button batteries must be distinguished from impacting of other foreign bodies because of their severe complications. We present a 2.5-year-old girl who had an acquired tracheo-esophageal fistula (TEF) caused by a calculator battery lodged in her esophagus. We also review the literature and assess the applicability of multislice CT and its possible advantages in children with acquired TEF.
