A sufficient surgical workspace is crucial to avoid complications. Within classic laparoscopy, many subjective surgical rating scales (SRSs) have previously been used to evaluate the surgical workspace. This study aimed to validate a modified version of the 5-point SRS during robot-assisted radical nephrectomy (RARN).
Thirty-two intra-operative videos of intraperitoneal spaces were recorded from eight patients who underwent RARN. To attain the visualisation of different types of workspaces, we recorded 20 s panoramic videos of different pneumoperitoneum, namely 3, 5, 7 and 12 mmHg. The videos were randomised and presented two times to eight experienced robotic surgeons to evaluate the workspace using our modified 5-point SRS. Both inter-and intra-rater reliabilities were tested.
The results of the validation study showed moderate inter-rater and good to excellent intra-rater reliability.
This is a valid tool that can be confidently used by future researchers in the field of robot-assisted surgery.
足够的手术空间对于避免并发症至关重要。在传统腹腔镜手术中，先前已经使用了许多主观手术评分量表（SRS）来评估手术空间。本研究旨在验证改良的 5 分 SRS 在机器人辅助根治性肾切除术（RARN）中的有效性。
从接受 RARN 的 8 名患者中记录了 32 个腹膜内空间的术中视频。为了获得不同类型手术空间的可视化效果，我们记录了不同气腹压力（3、5、7 和 12mmHg）下 20 秒的全景视频。视频被随机呈现两次，由 8 名经验丰富的机器人外科医生使用我们改良的 5 分 SRS 对手术空间进行评估。同时测试了组内和组间的可靠性。
验证研究的结果表明，该评分具有中度的组内可靠性和良好到优秀的组间可靠性。
这是一种有效的工具，未来机器人辅助手术领域的研究人员可以自信地使用。
