Gastric damage from ingested acid in children

Abstract 

Acid ingestion occurs relatively rarely and produces a spectrum of injury that is markedly different from the more commonly encountered alkaline burns of the oropharynx and esophagus. Gastric damage results from pylorospasm with pooling of the ingested caustic in a dependent location. Symptoms may be delayed for days or weeks. Perforation and/or strictures may require extensive gastric surgery. Early fiberoptic endoscopy is essential. (J Pediatr Surg 1985 Oct;20(5):494-6)
