During the years 1960 through 1989, 145 patients underwent sleeve lobectomy or sleeve resection of a main bronchus. Completion pneumonectomy was performed in 19 patients (13.1%). Indications were bronchostenosis without malignancy in 10 patients, positive resection margins in 3, recurrent tumor in 5, and anastomotic dehiscence in 1. Mean age at sleeve operation was 59.3 years. In 18 patients the histology was squamous cell carcinoma and in 1 patient, carcinoid tumor. The mean interval between sleeve resection and completion pneumonectomy was 5.7 months (range, 3 to 16 months) for the patients with stenosis and 6.6 months (range, 1 to 17 months) for the others. There were 3 operative deaths (15.8%). The mean follow-up was 53.2 months. Five-year and 10-year survival rates after completion pneumonectomy for the patients with stenosis were 54% and 41%, respectively, and for the others, 52% and 52%.
