Esophageal tracheobronchoplasty for diseases of the central airway

AbstractThree infants with congenital tracheal stenosis and three adults with various diseases of the central airway underwent esophageal tracheobronchoplasty to repair long-segment stenoses and defects. The primary operative goal was enlargement of the stenosis ( n = 4), repair of the defect ( n = 1), or both ( n = 1). Cardiopulmonary support was required in two cases. All three infants were operated on for generalized congenital tracheal stenoses. There was one postoperative death on the fifth day. Another infant died of pneumonia 3 months after operation. Tracheal patency was excellent in two infants. One infant is well without symptoms 6 years after the operation, although balloon dilation was required three times during the first postoperative year. In the three adult patients, the primary diseases were congenital tracheal stenosis, iatrogenic injury associated with relapsing polychondritis, and malignant mediastinal tumor involving the trachea. All lesions involved both the trachea and main stem bronchi. Postoperative airway patency was excellent in all three adults, although expandable metallic stents had to be inserted in one patient. Postoperative pulmonary function was improved, particularly forced expiratory volume in 1 second and peak expiratory flow rate. Although the postoperative mortality rate was still high, especially among the infants, and prolonged postoperative ventilatory support was required for five of the six patients, long-term patency and postoperative pulmonary functional improvement are encouraging.
