Between 1972 and 1982, 43 patients underwent sleeve resection for different types of bronchial tumors. A 5-year survival could be calculated for 23 patients (48%), which is in the range of simple lobectomy. In the patients with lymph-gland involvement, the 5-year survival was 40%, in those not radically resected, it was 25%. All of the latter received irradiation after resection. All patients who died 5 or more years after the first operation had second primary bronchial carcinoma. In 27 patients we were able to compare lung function before and after the operation. Only in 3 patients lung function tests after resection were worse than expected, due to greater asthmatic bronchial obstruction. Ventilation-perfusion scanning was also performed in 22 patients. Only 3 scans showed diminished perfusion, probably as a result of postoperative irradiation.
