Background Here, we report our initial experience with subxifoid video-assisted thoracoscopic surgery (SVATS) lobectomy for the management of primary lung cancer, and compared the outcomes of SVATS with those of conventional transthoracic VATS (CVATS) lobectomies to validate its feasibility and usefulness.Methods The clinical data of consecutive patients undergoing VATS lobectomy via SVATS or CVATS for lung cancer were retrospectively compared. The endpoints were to evaluate the statistical differences in surgical results, postoperative pain (measured with visual analog scale [VAS] scores at 8 hours, Day 1, Day 2, Day 3, at discharge, one month and three months after surgery) and paresthesia (measured at one- month, and three months after surgery). The two groups were compared before and after matching analysis.Results Our study population included 223 patients: 84 in the SVATS and 139 in the CVATS group.

These differences were overcome by propensity score matching (PSM) analysis that yielded two well-matched groups which included 61 patients in each group.
