[Reconstructive surgery in tracheobronchial tumors].

Malignant tumours are the most frequent indications for reconstructive tracheobronchial surgery. From 1970 to 15.6. 1989 there were 95 reconstructive operations on the tracheobronchial tree from this indication. Primary tumours of the trachea and the bifurcation are very rare, especially benign tumours. All tumours of the trachea and the bifurcation have need of a reconstruction, while this is an elective operation on the bronchial tree. The purpose of these operations is the preservation of lung tissue despite of radical resection. The main problem ist the insufficiency of the anastomosis (n = 6) associated with an acute pulmonary hemorrhage (n = 4) and death. The perioperative mortality was 9.5%.
