Robot-assisted thoracoscopic surgery using a narrow-profile vascular stapler through an 8-mm robotic port

The number of robot-assisted thoracoscopic surgery (RATS) procedures performed for thoracic disease has been increasing. Recently, a narrow-profile vascular stapler (Signia small-diameter reload, Covidien Japan, Tokyo, Japan) has been developed to provide superior access and precise staple placement in video-assisted thoracoscopic surgery (VATS) procedures. A 70-year-old man who was an exsmoker visited our hospital with a complaint of coughing. Chest computed tomography revealed a tumor with a cavity, ~55 mm in diameter, in the right-middle lobe. A 4-arm RATS right-middle lobectomy was performed with a 4-cm utility thoracotomy with da Vinci Xi (Intuitive Surgical, Sunnyvale, CA, USA). The pulmonary vessels were divided using a narrow-profile vascular stapler through an 8-mm port. No complications occurred in the postoperative course. With a narrow-profile vascular stapler, portal RATS can be performed after VATS lung biopsy using 8-mm ports.
