Background: Trachea-esophageal fistula (TEF) recurrence is frequent complication after esophageal atresia (EA) repair. Long new fistulas localized different from congenital TEF sites are called acquired TEFs (acq-TEF). We presented 4 cases to discuss diagnostic and management challenges in different localizations of acq-TEF.
Case report: We retrospectively evaluated the medical records of patients admitted with acq-TEF in last 5 years. From 16 postoperative TEFs, four TEFs were classified as acquired fistulas. Admission age was ranging from 1 to 8 years. Female/Male ratio was 2/2. The presented cases admitted with recurrent respiratory tract infections, choking, coughing. The acq-TEFs were between esophagus and cervical trachea, and right bronchus by passing through intrathorasic abscess cavity, and directly right bronchus, and between colon conduit and trachea. One of acq-TEF was healed spontaneously. Surgical fistula ligation was performed in others.
Conclusion: Acq-TEF is mostly seen secondary to local or diffuse mediastinitis. Besides its classical location of TEF, acq-TEF may be seen at unusual rare localizations such esophagus-to-right bronchus, and conduit-to-trachea. Acq-TEF may be seen at unusual rare localizations that should be kept in mind to evaluate and manage these patients more comprehensively.
