Surgery for Right Upper Lobe Lung Cancer in a Patient With Bridging Bronchus.

A 70-year-old man with back pain presented with a tumor invading the chest wall of his right upper lobe. Three-dimensional computed tomography revealed an aberrant right lower bronchus originating from the left main bronchus. Open thoracotomy right upper lobectomy with combined resection of the chest wall was performed under ventilation for the left and right lower lobes. The aberrant bronchus was defined as a bridging bronchus, a rare congenital anomaly. For such cases, careful planning is necessary to manage ventilation during operation. The area and extent of lymph node dissection are debatable.
