Right lower lobectomy and lymph node dissection for lung cancer with subcarinal bronchial diverticulum.

A tracheobronchial diverticulum is an incidental airway abnormality often identified on chest computed tomography. Thoracic surgery involves manipulation around the bronchial diverticulum, assessing its presence, and implementing appropriate strategies to prevent injury. However, few reports document cases of thoracic surgery complicated by a bronchial diverticulum. Herein, we report a case of surgical resection of lung cancer with a bronchial diverticulum. A 66 year-old woman was diagnosed with right lower lobe lung cancer, c-T1b N1 M0 stage IIB right lower-lobe lung cancer. Chest computed tomography showed a 9 mm bronchial diverticulum below the carina. Surgical intervention for bronchial diverticulum was performed simultaneously with the dissection of the inferior mediastinal lymph nodes. Right lower lobectomy with lymph node resection was safely performed using robot-assisted surgery.
