This study validates a new robotic surgery simulator for assessing surgical resident performance. The simulator effectively differentiates skill levels, showing high realism and utility for training in complex procedures.

Area of Science:

Medical Simulation
Surgical Training
Robotic Surgery

Background:

Assessing the validity of a novel robotic surgery task trainer.
Hypothesizing inter-cohort performance variations and differences between residents and fellows.

Purpose of the Study:

To evaluate the performance measurement validity of a new robotic surgery task trainer.
To determine if the trainer can differentiate between surgical resident and fellow performance.

Main Methods:

Developed a pelvic tumor model simulating unexpected bleeding for the da Vinci robot.
Participants (residents and fellows) performed tumor resection and hemostasis within 20 minutes.
Utilized a motion tracking system and post-participation surveys to assess performance and model utility.

Published on: December 6, 2024

Main Results:

Three of seven residents and one fellow successfully completed the task.
Residents exhibited significant variability in performance and blood loss (125-700 mL) compared to the fellow (150 mL).
All participants rated the simulator model as highly realistic and useful for training.

Conclusions:

The bleeding pelvic tumor simulator effectively discriminates resident performance in robotic surgery.
A multi-level assessment combining motion, decision-making, and blood loss metrics provides comprehensive performance evaluation.
The simulator demonstrates utility in assessing both technical skills and decision-making abilities in surgical trainees.
