Severe esophageal injuries caused by accidental button battery ingestion in children.
BACKGROUND
Button batteries represent a low percentage of all foreign bodies swallowed by children and esophageal location is even less frequent. However, these cases are more likely to develop severe injuries. The aim of this essay is to report three cases treated in our institution and review previous reports.


METHODS
Chart review and literature search.


METHODS
We treated three children between 2-7- years old with button batteries lodged at esophagus. They all presented esophageal burns (EB), which evolved in esophageal stenosis in two out of the three cases.


RESULTS
We found 29 more cases in literature and the injuries included EB, esophageal perforation (EP) and tracheoesophageal fistula (TEF).


CONCLUSIONS
Swallowed button batteries rarely remain in esophagus, but these cases present a higher risk of tisular damage. Injuries can take place even after few hours; and therefore, endoscopy must be performed as soon as possible. Further study on button batteries' safety and the establishment of a maximum size for them would be good preventive measures.
