Disc Battery in Esophagus

Extraction Case

Disc batteries are one of the most dangerous choking hazards, because they can burn through the esophagus (in as little as 6 hours) and cause a serious chest infection.

Radiographically, some disc batteries look exactly like a coin (potentially delaying diagnosis and treatment). In this case, xrays showed the “double ring” sign which most disc batteries make.

Please keep disc batteries out of reach of young children.
