Robotic Surgery and Anatomic Segmentectomy: An Analysis of Trends, Patient Selection, and Outcomes

Abstract

Background: Whether robotic segmentectomies are advantageous is unclear. We describe our experience with the robot, comparing patient populations and outcomes with video-assisted thoracoscopic surgery (VATS) and open resection. Methods: Patients who underwent anatomic segmentectomy from 2004 to 2019 were reviewed. Resection methods were categorized as robotic, VATS, or open. Segmentectomies were categorized as simple or complex. Baseline characteristics and perioperative outcomes were analyzed from 2015 to 2019 due to implementation of the Enhanced Recovery After Surgery pathway for all thoracic surgery patients and to thus minimize confounders resulting from the Enhanced Recovery After Surgery protocol. Results: Since 2004, an increase has occurred in segmentectomies, including robotic and complex segmentectomies. Of the 222 segmentectomies performed from 2015 to 2019, 77 (35%) were robotic, 40 VATS (18%), and 105 open (47%). More complex segmentectomies were performed in the robotic group compared with VATS and open (45% vs 15% vs 22%; P
