Abstract
We treated a 58-year-old man with a large squamous cell lung carcinoma occupying S6. Bronchoscopy revealed a polypoid tumor protruding to the truncus intermedius and almost occluding the lower lobe bronchus. At operation we found that the volume of the middle lobe was as large as that of the upper lobe. Right lower sleeve lobectomy with anastomosis of the truncus intermedius to the middle lobe bronchus was performed. Postoperative bronchoscopy revealed good patency of the anastomotic site. Postoperative respiratory function tests showed a decrease of only 13% in both vital capacity and forced expiratory volume in one second.
