[Right lower lobectomy with flap bronchoplasty for primary lung cancer]

A 59-year-old man was referred to our hospital for further investigation of an abnormal chest shadow. A chest computed tomography( CT) revealed a tumor shadow originating in the superior segment( S6)of the right lower lobe. Bronchoscopy showed no visible tumor, but adenocarcinoma cells were detected in brush cytology samples. We diagnosed primary lung cancer, classified as cT2aN0M0, and planned a radical operation. Intraoperatively, since the tumor had invaded the outer wall of intermediate bronchus, we considered a flap bronchoplasty to preserve the middle lobe. The right lower lobectomy and partial resection of intermediate bronchus were made with preserving unaffected ventral wall of lower bronchus. The lower bronchus remnant was used as a flap to cover the defect in the intermediate bronchus. The postoperative course was uneventful, and bronchoscopic findings revealed good healing of the suture line and sufficient airway patency.
