Abstract
Objective:
This study aimed to compare the perioperative outcomes of robot-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) for lung cancer in patients with obesity.
Methods:
Anatomical pulmonary lobectomy or segmentectomy performed at a single institution from April 2018 to September 2023 in patients with obesity (body mass index ≥25 kg/m2) were statistically compared in terms of perioperative clinical factors including operative time, blood loss, chest tube duration, pain score, intraoperative events, and early postoperative complications between RATS and VATS.
Results:
In all, 89 patients were evaluated; 43 underwent RATS and 46 underwent VATS. All RATS procedures were performed using the da Vinci Xi system. Patient characteristics were comparable between the 2 groups. The operative time, blood loss, number of dissected lymph nodes, intraoperative events, and conversion rate to open thoracotomy were similar between the 2 groups. The frequencies of postoperative complications and chest tube placement duration between the groups were also similar. The median pain scores were slightly higher in the RATS group on postoperative day 1 but were equivalent between the 2 groups on postoperative day 7. The RATS group had a shorter postoperative hospital stay than the VATS group (P < 0.01).
Conclusions:
A surgical team proficient in conventional VATS can safely introduce RATS in patients with obesity and lung cancer with equivalent perioperative outcomes.
