Endoscopic Findings Associated w/ Button Battery Ingestion in Children
Foreign body (FB) ingestion is a very common problem in children and a cause for presentation to the emergency department (Rios et al., 2020).
Button batteries (BB) given their corrosive properties, can damage gastrointestinal (GI) mucosa and cause serious injury within a few hours.
3 mechanisms of mucosal injury have been described for BBs:
leakage of battery content directly corroding adjacent mucosa
burns due to electric current
necrosis due to direct compression
Esophageal mucosal lesion occurs within a very short time after ingestion, then current recommendation is BB removal within 2 hours of ingestion (Rios et al., 2020).
Button battery ingestion is an accident that occurs mainly at home and is more common in children younger than 6 years.
It is imperative to keep in mind that being asymptomatic does not rule out the presence of an FB and that mucosal damage may still be present.
