Other related information

This study is exploratory, not a comparative controlled trial, and is conducted using surgical videos of laparoscopic gastrectomies, with no direct impact on patients. Therefore, consent is obtained through an opt-out approach, and due to the lack of necessity for strict randomization, a randomization center will not be established.
