Initial Surgical Results of Subcostal Single-Port Robotic Lung Resection: A Comparative Analysis With the Multi-Port Robot.

BACKGROUND

The da Vinci SP enables single-port robot-assisted thoracoscopic surgery and this modality represents a novel approach to lung resection via the subcostal arch technique. We implemented this technique at our institution, performed 30 surgeries, and then compared the outcomes with those of surgeries using the da Vinci Xi system.

METHODS

Thirty consecutive patients in each group with stage I-III lung cancer, who were all operated on with da Vinci SP and Xi, were compared.

RESULTS

The SP group included 24 lobectomies and 6 segmentectomies. The Xi group included 16 lobectomies, 1 bilobectomy, and 13 segmentectomies. No conversion was required in either group. An additional port was needed in two cases in the SP group. There were no significant differences in the perioperative outcomes between the SP and Xi groups. Postoperative complications occurred in two patients in the SP group and nine patients in the Xi group. No complications classified as Clavien-Dindo grade ≥ 3 were observed in the SP group.

CONCLUSIONS

Anatomic lung resection using the da Vinci SP system demonstrated outcomes that were comparable to those of the da Vinci Xi system.
