Description
Annika Köhler and co-authors published this simulator evaluation in 2026. Stomach bleeding is a common emergency where endoscopists must act fast and precisely. Training chances are limited and often rely on animal models. OPTESK is a new open-source virtual reality simulator built for this task, pairing a real clinical endoscope with a headset. It offers two scenarios: treating a quiet vessel malformation, and stopping an actively bleeding one with adrenaline injection plus heat therapy.
Forty-four participants from over twenty centers tried it. Nearly all, 97.4 percent, achieved bleeding control in the emergency scenario. Users rated its training helpfulness and realism at a median of four out of five. Workload felt moderate and usability acceptable. Experienced endoscopists finished tasks significantly faster than novices, evidence the simulator measures real skill. The authors conclude OPTESK can prepare trainees safely before they face real bleeding, reducing reliance on animal practice.
