title: Postoperative airway stenosis and stent therapy in carinal reconstruction for lung cancer.
abstract: A 48-year-old male had adenocarcinoma of the right upper lung lobe that invaded the lower trachea. The right upper lobe, the carina, and 5 rings of the lower trachea were resected. The carina was reconstructed using end-to-end anastomosis between the trachea and right intermediate bronchus, with the left main bronchus anastomosed to the side wall of the intermediate bronchus. Two months after surgery, the right intermediate bronchus developed bronchomalacia and the tracheal anastomosis granulatory stenosis. Bronchomalacia was treated with 2 expandable metallic stents, and granulatory stenosis with a Dumon stent. Although the silicone stent successfully dilated the granulatory stenosis, the metallic stents caused delayed glanulatory stenosis. We concluded that a metallic stent is not desirable for treating postreconstructive airway stenosis including bronchomalacia, whereas a Dumon stent may be effective.
