Comment on: "Complex lung segmentectomy: comparative perioperative outcomes of robotic and video-assisted approaches".

This commentary evaluates a propensity-matched study by Nakamura et al. comparing robotic-assisted (RATS) versus video-assisted complex segmentectomy. The original study demonstrated that despite longer operative times, RATS achieved comparable perioperative outcomes with significantly fewer postoperative arrhythmias. While methodologically robust, limitations include the retrospective design, the absence of long-term oncologic data, and a lack of cost-effectiveness analysis. Furthermore, the potential influence of surgeon proficiency on outcomes was not assessed. Future multicenter prospective registries with comprehensive outcome measures are needed to validate these findings.
