Abstract

|
|
Background: Tracheoesophageal fistula (TEFs) is a rare condition that requires complex surgical treatment. We analyzed the surgical outcomes of TEF reported in the literature and at Pusan National University Yangsan Hospital using standardized techniques.
Methods: This retrospective study included 8 patients diagnosed with acquired benign TEF between March 2010 and December 2019. The surgical method was determined based on the size of the fistula observed within the endoscope.
Results: TEF occurred in 7 patients (87.5%) after intubation or tracheostomy and in 1 patient (12.5%) after esophageal surgery due to conduit necrosis. For tracheal management, 5 and 2 patients underwent tracheal resection and end-to-end anastomosis and primary repair, respectively. The median length of resection was 2.5 cm (range, 1.3?3.4 cm). For esophageal management, 6 patients underwent primary repair and 1 patient underwent esophageal diversion. One patient underwent TEF division with a stapler. Interposition of a muscle flap was performed in 2 patients. TEF recurrence, esophageal stenosis, and dehiscence or granulation occurred in 1, 1, and 2 patients, respectively. A long-term tracheostomy tube or T-tube was used in 2 patients for >2 months.
Conclusion: Although TEF surgery is complex and challenging, good results can be achieved if surgical standards are established and experience is accumulated.
