Caustic ingestion in children.

Caustic ingestion continues to be a significant problem worldwide especially in developing countries. In 2008 over 200,000 exposures to caustic substances were reported to the National Poison Data System. The presence or absence of symptoms or oral lesions does not predict the existence or severity of lesions. The best predictor of morbidity and mortality is the extent of injury as assessed during initial evaluation. Upper endoscopy remains the mainstay diagnostic modality for the evaluation of patients with caustic ingestion. There is a pressing need for noninvasive diagnostic modalities and effective therapeutic options to evaluate and treat the complications associated with caustic ingestion.
