Common features of caustic ingestions include dysphagia, odynophagia, epigastric pain, and vomiting with gastrointestinal (GI) tract injuries. Dysphonia, stridor, and respiratory distress can be seen with laryngotracheal injury. Esophageal injuries are graded by direct visualization: (1) edema and hyperemia; (2) ulcerations, blisters and exudates (2a-noncircumferential; 2b-circumferential); (3) deep ulceration and necrosis. Intentional ingestions are associated with higher-grade injury that can lead to the development of strictures. Most ingestions with serious injury are symptomatic with stridor, drooling, or vomiting, although distal GI injury without oral or facial burns is possible. Disc battery ingestions may be asymptomatic, though batteries >15 mm in diameter can become lodged in the esophagus and cause pressure necrosis.
