ORMENO JULCA, Alexis José  e  ECHEVARRIA LOPEZ, Nora Flor. Are strange radiopaque bodies with double contours in the digestive tract always button cell batteries?. Rev Col Gastroenterol [online]. 2020, vol.35, n.1, pp.114-117. ISSN 0120-9957.  https://doi.org/10.22516/25007440.326.

Accidental ingestion of foreign bodies constitutes an emergency for pediatric care services especially since the group most frequently affected consists of children between 6 months and 3 years of age. Ingestion of button cell batteries has high risks for severe early complications such as esophageal perforations and mediastinitis, as well as the long term risk of stenosis. Early identification and extraction are the most important management strategies. A double contour on a frontal cervical, thoracic, or abdominal x-ray is characteristic, but this same radiological sign has been reported for other foreign bodies. We present two cases with these characteristics.
