Bronchoplastic surgery for lung cancer and the results.

Fifty-nine patients with lung cancer underwent bronchoplastic surgery in our institute from September, 1965 to May, 1982. The post surgical stages of disease were as follows: 7 cases of Stage I disease, 7 cases of Stage II, 41 cases of Stage III, 4 cases of Stage IV. The bronchoplastic surgery performed included sleeve resection combined with lobectomy in 35, wedge resection combined with lobectomy in 11, reconstruction of the lower area of the trachea in 5, bronchial sleeve resection combined with pulmonary artery resection in 6 and bronchial wedge resection combined with pulmonary artery resection in 2. There was no case of operative mortality within 30 days after the operation. To prevent postoperative complications, careful techniques are required in suturing and postoperative bronchoscopic suction of intrabronchial secretion is necessary. The use of Dexon or Dexon S, polyglycolic acid sutures, showed good results. Adjuvant therapies were performed on 42 cases, including preoperative infusion of Mitomycin C into the bronchial arteries or postoperative irradiation or both. Twenty-eight of 59 were alive and well from 7 months to 16 years after the operations. The relative 5 year survival rates were 40.5 per cent in total cases and 46.5 per cent in those with squamous cell carcinomas. The prognosis of patients undergoing bronchoplasty was compared with that of patients undergoing lobectomy and pneumonectomy. There was a statistical difference between bronchoplasty and pneumonectomy.
