Early Adoption of Robotic Pulmonary Lobectomy: Feasibility and Initial Outcomes

Abstract

Despite the published benefits of minimally invasive video-assisted thoracoscopic surgery (VATS) for lobectomy, the majority of lobectomies in the United States continue to be performed through a thoracotomy. The low adoption rate of VATS has been attributed to its technical challenges and ergonomic inefficiencies. Robotic surgery has been proposed as an alternative minimally invasive technique that allows the replication of open lobectomy with wristed instruments and three-dimensional vision. Our aim was to analyze the transition from open to robotic lobectomy at our hospital where there had been no significant VATS lobectomy experience. We analyzed 88 open and 43 robotic lobectomies that met criteria for inclusion. Operative times were significantly longer with the robotic group but decreased with experience. The resection time of the latter half of the robotic cases decreased to within 20 minutes of the open cases. There were no conversions in the robotic cases to either VATS or open. Robotic lobectomy was associated with faster postoperative recovery with a 60 per cent decrease in length of stay. Complications were uncommon and there were no deaths in the robotic group. We conclude that the transition from open to robotic lobectomy can be achieved safely with excellent postoperative outcomes. This new technique is a viable alternative to VATS lobectomy.
