BACKGROUND: Telepresence enables real-time observation and remote mentoring across distances, potentially accelerating the dissemination of advanced minimally invasive techniques. The da Vinci 5 platform integrates Telepresence within the My Intuitive digital ecosystem, facilitating remote case observation, collaboration, and mentoring.
METHODS: This technology paper reports an international telepresence session in which an expert colorectal robotic surgeon located in Daegu, Republic of Korea, provided real-time remote mentoring during a robot-assisted colorectal procedure performed in Saitama, Japan. A representative clinical implementation involved a patient with rectosigmoid cancer (clinical stage T1bN0M0) and obesity (BMI 30.1 kg/m2). The telepresence-mentored segment focused on the most technically demanding phase: peritoneal incision, dissection around the superior rectal artery (SRA), and vascular handling.
RESULTS: The mentored phase lasted 40 min. During this segment, the remote mentor provided step-by-step guidance on exposure strategy, traction direction, and plane selection. Additionally, console-integrated objective force visualization ("Force Gauge") was used as a shared reference to optimize retraction. The operation was completed without intraoperative complications (operative time: 214 min; estimated blood loss: 5 mL).
CONCLUSION: These findings demonstrate the feasibility of cross-border telepresence mentoring on the da Vinci 5 platform. Coupling remote mentoring with objective intraoperative force feedback may improve shared situational awareness and support safe decision-making during complex robotic colorectal surgery.
