腹腔鏡下大腸がん手術におけるロボットおよび手動スコープホルダーの比較

To compare the performance of a robotic (da Vinci Xi-based) scope holder with manual holding during laparoscopic colorectal cancer (CRC) surgery.

A total of 170 CRC cases were retrospectively assigned to two equal groups: an investigation group (da Vinci Xi-assisted procedures) and a reference group (human camera assistant). Surgical and recovery outcomes were analyzed, including pain intensity, stress levels, and gastrointestinal and humoral immune functions. Additionally, the safety of the procedures and surgeons' subjective experiences were evaluated.

The investigation group showed significant improvements, including reduced blood loss, shorter surgical duration, earlier drain removal and discharge, lower costs, and less post-operative pain (24, 48, and 72 hours post-surgery). This group also exhibited lower stress levels, fewer complications, and better recovery in terms of gastrointestinal and humoral immunity (all P<0.05). Surgeons in the investigation group reported higher scores for procedural vigor, operational efficiency, and comfort (P<0.05).

The robotic system offers clinical advantages in laparoscopic CRC procedures.
