Gastric and esophageal dysfunction after ingestion of acid.

Esophageal and gastric function was measured in a patient who swallowed a household acid solution. Dysphagia, transient ulceration of the esophagus with luminal narrowing, and complete loss of peristalsis without loss of lower esophageal sphincter function were noted. Gastric dysfunction appeared 2 weeks after ingestion with complete obstruction, necessitating antral resection. The proximal stomach was relatively spared.
