The use of robotics for lung resection has increased significantly over the past several years. We favor a completely portal 4-arm approach. Left upper lobectomy, which many believe is the most complex of the 5 lobectomies, is well-suited for robotic assistance. Port placement and conduct of the operation are described. Robotic left upper lobectomy can be done with minimal morbidity and extremely low perioperative mortality, with similar postoperative and oncological results when compared with video-assisted thoracoscopic surgery lobectomy.
