A novel endoscopy training system by video-based asynchronous communication

Although instruction by experienced endoscopists is preferable for improving trainees’ endoscopic skills [1] [2] [3] [4], this is not always achievable in clinical practice because of manpower shortages or other circumstances. Recently, synchronous training (e. g. hands-on seminars) has become popular among endoscopy trainees. However, the opportunities to attend these events are limited and effective instruction is difficult to achieve in a short time. Tsucom (BonBon Inc., Kyoto, Japan) is an online platform supporting video-based asynchronous communication [5]. This platform allows intra-group communication at any time and place via addition of reactions by text and audio to uploaded videos ([Fig. 1]). Herein, we demonstrate our novel training system using Tsucom for an endoscopic procedure in a porcine model ([Video 1]).

Video 1 Demonstration of our novel endoscopy training system using Tsucom (BonBon Inc., Kyoto, Japan) for endoscopic submucosal dissection in the porcine stomach.

This demonstration was designed for a situation where a trainee could not receive direct instruction from instructors. The trainee performed endoscopic submucosal dissection on the porcine stomach and recorded the intraoperative endoscopic field. The endoscopic maneuver was also recorded with a 360° camera (Insta360; Arashi Vision Inc., Shenzhen, China) worn around the neck ([Fig. 2]). The two video files were merged into one ([Fig. 3]) and then uploaded to the platform. Two instructors respectively reviewed the video on the platform, and then used text and audio to point out how to improve the procedure. The 360° camera allowed free movement of the viewpoint and focus on any part of the endoscopic maneuver. The posted comments were overlaid directly onto the video and synced to specific playback times. While rewatching the commented video, the trainee could simulate an experience of real-time instruction and obtain sufficient feedback ([Fig. 4]).

This endoscopy training system may provide a preferable learning environment for endoscopists who are unable to receive sufficient hands-on training or post-training feedback, not only within a specific facility, but across countries and regions.
