Core Tip

Core Tip: The early acquisition of endoscopic hemostasis skills may be hindered by the lack of tools for assessing the operator’s viewpoint. We validated the effects of a training system that allowed an understanding of the operator’s gaze pattern during gastric endoscopic submucosal dissection on hemostasis. The time required to recognize the bleeding point was shorter after gaze pattern education using the training system. The number of coagulation attempts was fewer after the education. Learning from the operator’s viewpoint can facilitate acquiring the skills required to achieve hemostasis during endoscopic submucosal dissection.
