Summary
A modified 5-point surgical rating scale (SRS) was validated for robot-assisted radical nephrectomy (RARN). This tool reliably assesses surgical workspace, proving valuable for future robot-assisted surgery research.
Area of Science:
- Urology
- Surgical Robotics
- Surgical Education
Background:
- Sufficient surgical workspace is critical for minimizing complications in laparoscopic surgery.
- Subjective surgical rating scales (SRSs) have been used to evaluate workspace in traditional laparoscopy.
- Robot-assisted radical nephrectomy (RARN) requires objective workspace assessment.
Purpose of the Study:
- To validate a modified 5-point SRS for assessing the surgical workspace during RARN.
- To determine the reliability of the modified SRS in a robotic surgery context.
Main Methods:
- Thirty-two intra-operative videos of intraperitoneal spaces during RARN were recorded from eight patients.
- Videos captured different pneumoperitoneum pressures (3, 5, 7, 12 mmHg) to visualize diverse workspaces.
- Eight experienced robotic surgeons evaluated randomized videos using the modified 5-point SRS, with inter- and intra-rater reliability tested.
Main Results:
- The validation study demonstrated moderate inter-rater reliability.
- Good to excellent intra-rater reliability was observed for the modified SRS.
Conclusions:
- The modified 5-point SRS is a valid tool for evaluating surgical workspace in RARN.
- This validated scale can be confidently employed by researchers in robot-assisted surgery.
