A Case of Delayed Tracheo-esophageal Fistula Complicating Acute Intoxication of Hydrogen Peroxide

ABSTRACT

Hydrogen peroxide is a commonly used oxidizing agent. If injected, it may result in morbidity via direct caustic injury, oxygen gas formation, and lipid peroxidation. We report a 40-year-old male patient who accidentally swallowed undiluted hydrogen peroxide (35%). The initial chest computed tomography scan showed no active lesions. He was admitted to the intensive care unit for conservative treatment. Fourteen days after treatment, uncontrolled fever and foul oder sputum occurred, which was not alleviated despite empirical antibiotics therapy. Findings on a chest computed tomography showed tracheo-esophageal fistula at the lower trachea and left main bronchus. He underwent surgical replacement surgery and was discharged without complication after 52 days of admission.
