Tracheoesophageal fistulas are uncommon and present diverse etiologies, among which is burning of the esophagus due to caustic ingestion. Herein, we report the case of a 27-year-old male patient having ingested a caustic substance 14 days prior and presenting burning retrosternal pain, weakness, productive cough with purulent sputum and dyspnea accompanied by hoarseness for the preceding 24 h. Endoscopy of the upper digestive tract revealed a tracheoesophageal fistula. Treatment consisted of cervical exclusion of the esophageal transit, together with gastrostomy. Subsequently, the nutrient transit was reconstructed through pharyngocoloplasty. The postoperative evolution was favorable.
