Corrosive injury to the stomach due to acid ingestion.

Ingestion of acid often causes severe damage to the stomach. Ingestion of alkali, however, usually injures the esophagus and spares the stomach. Early complications of acid ingestion, e.g., massive gastric hemorrhage or perforation, are unusual. The absence of severe symptoms in most patients soon after ingestion of acid is often misleading. Gastric outlet obstruction is a common late result and may develop following an asymptomatic interval. The authors' experience with three patients with severe complications following ingestion of acid is presented. The initial treatment, as well as the surgical management, are discussed.
