摘要

Purpose

This study compared the peri- and postoperative outcomes of robot-assisted thoracic surgery (RATS) and video-assisted thoracic surgery (VATS) lobectomy for primary lung cancer.

Methods

This retrospective cohort study included patients who underwent RATS or VATS at Nagoya University Hospital between April 2018 and March 2022. Propensity score matching was used to balance patient characteristics between the two groups. The following long-term outcomes were assessed: the 3-year overall survival (OS), causes of death, 3-year disease-free survival (DFS), and recurrence patterns. Various peri- and postoperative outcomes were examined as short-term outcomes.

Results

After propensity score-matching, 137 patients were included in each group. RATS was associated with a longer operative time (median 180 vs. 144 min, p < 0.001), less blood loss (median 5 vs. 12 ml, p = 0.005), and a lower rate of conversion to open thoracotomy (1 [0.7%] vs. 10 [7.4%], p = 0.010) than VATS. The 3-year OS and DFS were comparable between the groups.

Conclusion

In lobectomy for lung cancer, RATS demonstrated long-term outcomes that were comparable to those of VATS. Although RATS has a longer operative time, it is associated with less blood loss and a lower conversion rate to open thoracotomy than VATS, suggesting that it is a beneficial surgical approach for patients.
