Summary
This study shows cross-border telepresence mentoring is feasible for robotic colorectal surgery using the da Vinci 5 platform. Objective force feedback enhances situational awareness and decision-making for complex procedures.
Area of Science:
- Robotic Surgery
- Surgical Technology
- Medical Education
Background:
- Telepresence facilitates remote observation and mentoring, accelerating advanced minimally invasive technique adoption.
- The da Vinci 5 platform integrates Telepresence for remote case observation, collaboration, and mentoring within the My Intuitive ecosystem.
Purpose of the Study:
- To report on an international telepresence session for remote mentoring in robot-assisted colorectal surgery.
- To evaluate the feasibility and impact of remote mentoring on complex surgical phases.
Main Methods:
- An expert surgeon in South Korea remotely mentored a robot-assisted colorectal procedure in Japan using the da Vinci 5 platform.
- The focus was on the peritoneal incision, superior rectal artery (SRA) dissection, and vascular handling in a patient with rectosigmoid cancer.
- Objective force visualization (Force Gauge) was utilized for enhanced retraction guidance.
Main Results:
- The mentored phase lasted 40 minutes, with the remote mentor providing guidance on exposure, traction, and plane selection.
- The surgery was completed without intraoperative complications (operative time: 214 min; estimated blood loss: 5 mL).
Conclusions:
- Cross-border telepresence mentoring on the da Vinci 5 platform is feasible for complex robotic colorectal surgery.
- Integrating remote mentoring with objective intraoperative force feedback can improve shared situational awareness and support safe decision-making.
