Aortoesophageal Fistula Due to Caustic Ingestion

PurposeCaustic agent ingestion may produce corrosive lesions that can extend beyond adjacent organs. We report three cases of aortoesophageal fistulas (AEF) after caustic ingestion that were diagnosed by autopsy.ResultsAEF is a fatal complication that should be suspected in any patient with caustic ingestion who presents with gastrointestinal bleeding. A high index of suspicion, early recognition by gastrointestinal endoscopy, computed tomography scan, and aortography are important to improve the outcome
