In Stage I, an appropriate pedicled myocutaneous flap was selected and prepared based on the patient's surgical history. Then, the thoracostomach was removed transthoracically to expose the tracheal fistula, and the pedicled myocutaneous flap was used to repair the fistula by anastomosing it to the airway.

One patient developed a tracheal-myocutaneous flap anastomotic leakage 1 week after surgery, resulting in chronic empyema.
