Since 2020, we have conducted an online colorectal endoscopic submucosal dissection (ESD) training course, holding 9 sessions and training a total of 75 participants. The aim of this study is to evaluate the effectiveness of our remote hands-on training program for colorectal ESD.</div></div><div><h3>Methods</h3><div>Using a wired 50 Mbps connection, we linked a central facility to 3 remote sites across Japan. A 4-screen Picture-in-Picture (PinP) video integrating hand, scope, posture, and endoscopic views was streamed for real-time demonstration. Each participant underwent a structured 70-minute training session consisting of an initial and final time trial using the Scope handling Training (ST) kit, endoscope handling practice, and hands-on ESD training with an artificial model. During the remote hands-on phase, trainees performed procedures while receiving real-time instruction from experts via a Picture-in-Picture video system, which displayed both the endoscopic view and hand movements. There were no detectable delays in audio or video communication, enabling seamless 2-way interaction.</div></div><div><h3>Results</h3><div>The results of the ST kit time trials conducted before and after the training showed a significant improvement in speed after the training (from 89.3 seconds before training to 49.4 seconds after training).
