A novel endoscopy training system by video-based asynchronous communication

概要

Although instruction by experienced en- doscopists is preferable for improving trainees’ endoscopic skills [1–4], 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 trai- nees. However, the opportunities to at- tend these events are limited and effec- tive instruction is difficult to achieve in a short time. Tsucom (BonBon Inc., Kyoto, Japan) is an online platform supporting video-based asynchronous communica- tion [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 proce- dure in a porcine model (▶ Video 1). This demonstration was designed for a situation where a trainee could not re- ceive direct instruction from instructors. The trainee performed endoscopic sub- mucosal dissection on the porcine stom- ach and recorded the intraoperative en- doscopic field. The endoscopic maneu- ver 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 com- ments were overlaid directly onto the vi- deo and synced to specific playback times. While rewatching the commented video, the trainee could simulate an ex- perience of real-time instruction and ob- tain sufficient feedback (▶ Fig. 4). This endoscopy training system may pro- vide a preferable learning environment for endoscopists who are unable to re- ceive sufficient hands-on training or post-training feedback, not only within a specific facility, but across countries and regions.
