[Tracheoesophageal fistula]

Abstract

Congenital deformities, various forms of trauma, foreign bodies, granulomatous infection and tumors are the most common causes of tracheoesophageal fistulas. This is a rare but life-threatening complication with mortality rates up to 60% due to chronic aspiration and innominate artery arrosion and bleeding. Bronchoscopy should be done promptly if a fistula is suspected, followed by esophagoscopy. Radiologic examinations are only helpful for operational planning. Surgical treatment is mandatory for benign fistulas with excellent short-term and long-term results. However, for malignant fistulas the survival time is often only weeks to months and are best treated by palliative stenting, which offers a short-term improvement in the quality of life.
