| 概要 | PURPOSE:The hinotori™ surgical robot system (hinotori) is the first Japanese-made surgical robot. We conducted this study to compare the short-term outcomes of robotic surgery for colorectal cancer between the hinotori and da Vinci Xi systems during the same period.METHODS:This retrospective study included 204 patients who underwent robotic colorectal cancer surgery at our institution between June 2024 and September 2025. Patients were classified into hinotori (n = 78) and da Vinci Xi (n = 126) groups. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to adjust for patient and tumor characteristics.RESULTS:After adjustment, the baseline demographics were well-balanced between the groups. No significant intergroup differences were observed in operative time, console time, blood loss, or postoperative hospital stay. Both groups had comparable histopathological outcomes. The incidence of Clavien-Dindo grade ≥ II complications did not differ significantly between the two groups after PSM or IPTW adjustments.CONCLUSIONS:This study showed that robotic colorectal surgery using the hinotori system is as safe and feasible as surgery performed using the da Vinci Xi system. |
