Thoracoscopic right S6 sleeve segmentectomy for squamous-cell carcinoma arising from the B6 central bronchus.

We describe a patient with low respiratory function who underwent thoracoscopic sleeve segmentectomy to preserve lung function as much as possible. The patient had already used home oxygen therapy because of chronic obstructive lung disease. There was a squamous-cell carcinoma at inlet of right B6 bronchus, and cT1aN0M0 disease was diagnosed. Because respiratory function was poor, right S6 segmentectomy was scheduled. Moreover, to preserve the respiratory muscles as much as possible, a thoracoscopic approach was selected. We performed S6 sleeve segmentectomy, and sutured the lower bronchus and basal bronchus. There were some limitations in handling needles during thoracoscopy. To resolve these difficulties, we devised two techniques. One was to suture the bronchus with continuous sutures on the mediastinal side and simple interrupted sutures on the other side. The other was to create a working space for handling the needles to avoid entanglement of the sutures. These techniques allowed us to suture the bronchi relatively easily.
