This study retrospectively reviewed patient data from 2004 to 2019 and compared patient populations and outcomes between robotic surgery, VATS, and open surgery for segmentectomy. The results showed that despite longer operative time, robotic segmentectomy had lower blood loss, shorter chest tube days, and shorter lengths of stay compared to VATS and open surgery. There were no conversions from robotic to open surgery, and the occurrence of prolonged air leak was lower in the robotic group compared to open surgery.
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 < .001). Operative time for robotic resections were longer compared with VATS and open (205 vs 147 vs 147 minutes; P < .001) but had lower blood loss (50 vs 75 vs 100 mL; P < .001) and shorter chest tube days (2 vs 2 vs 3 days; P = .004) and lengths of stay (3 vs 3 vs 4 days; P < .001). Perioperative mortality was low in all groups. No robotic segmentectomy was converted to open compared with 7.5% for VATS (P = .038). Prolonged air leak was lower for robotic compared with open (4% vs 13%; P = .038). CONCLUSIONS Robotic segmentectomy has increased in our institution, with a concurrent rise in atypical segmentectomies. Despite performing more complex procedures, there were no conversions and low perioperative morbidity and mortality. Our results suggest that the robotic platform can facilitate performance of complex anatomic segmentectomies.
