[Congenital tracheoesophageal fistula; report of an adult case].

We experienced an adult case of congenital tracheoesophageal fistula which was successfully treated by surgical intervention. A 69-year-old female was admitted with complaint of coughing and fever. The patient previously had had several episodes of pneumonia. Esophagography and thoracic CT demonstrated a tracheoesophageal fistula in the upper of the thoracic esophagus. Following the resection of the fistula, the trachea was closed with one layer suture and the esophagus was closed with two layer sutures. A pedicled fifth intercostal muscle was interposed between the tracheal and esophageal suture lines. There was mild inflammatory change in surrounding tissues of the fistula. Pathological examination revealed that the fistula was covered with the squamous epithelium, and had the muscularis mucosa. Her postoperative course was uneventful.
