Objective:
This study aimed to investigate the outcomes of robot-assisted lung resection using the hinotori™ surgical robot system.
Methods:
Between June 2024 and November 2025, four thoracic surgeons performed 21 lung resections with the hinotori™ and 78 lung resections with the da Vinci Xi. Patient characteristics, operative variables and postoperative outcomes were compared between the two surgical robot groups.
Results:
The patient characteristics were similar between the groups. The hinotori group showed a significantly longer median operative time (265 min) than the da Vinci group (195 min; P ≤ 0.001). One patient in the hinotori group required conversion to video-assisted thoracoscopic surgery, whereas two patients in the da Vinci group required conversion to open thoracotomy. Intraoperative blood loss was minimal in both groups. There was no significant difference in the postoperative outcomes, including the duration of chest tube drainage and hospital stay, between the groups. Postoperative complications (Clavien-Dindo grade ≥ 2) were observed in 3 patients (14.3%) in the hinotori group and 10 patients (12.8%) in the da Vinci group (P > 0.999).
Conclusions:
Robot-assisted anatomical lung resection using the hinotori™ was feasible in selected patients. Further studies are warranted to establish its comparative safety.
