    Abstract:
    PURPOSE: The aim of the study is to investigate whether a tracheoesophageal fistula (TEF) found after the primary repair of type C esophageal atresia (EA) is a recannulation of the original fistula, a missed proximal fistula, or other rare foregut malformation. METHODS: Between 2000 and 2009, 143 different types of patients with EA were admitted in our hospital. Seven patients (2 from our series, 5 referred to us by other hospitals with the history of primary repair of type C EA) had late presenting TEF. Esophagogram, 3-dimensional computed tomographic (CT) reconstruction, bronchoscopy, and reoperation were performed to confirm the TEF. Their medical records were reviewed and summarized. RESULTS: Persistent feeding or respiratory problems were the common symptom. The mean age of the first appearance was 17 ± 26 (1-63) months. Preoperative diagnosis was made by esophagograms and bronchoscopy in 6 patients. Reoperations were performed in all patients through thoracotomy. Missed proximal TEF shown as a distinct fistula above the primary anastomosis without much adhesion was confirmed in 5 cases. A recurrent TEF was found in 1 case. A case of communicating bronchopulmonary foregut malformation was confirmed by 3-dimensional CT reconstruction and reoperation. CONCLUSION: A missed proximal TEF after repair of EA may be misdiagnosed as a recurrent TEF. Accurate preoperative diagnosis depends on combined evaluations of radiologic contrast study, 3-dimensional CT, and bronchoscopy.
