    Endoscopic submucosal dissection (ESD) allows for complete tumor removal with minimal invasiveness, improving patient outcomes in gastrointestinal diseases.

  • 2

    Traditional training for ESD faces limitations, including biomechanical differences in animal models and ethical concerns with live animal use.

  • 3

    A novel 3D-printed gastric ESD training model was developed using dual-network composite hydrogels to replicate human gastric wall stratification.

  • 4

    The training model incorporates simulated bleeding responses and tunable stiffness to enhance realism and training effectiveness for endoscopists.

  • 5

    Evaluation of the model showed high realism ratings and positive feedback on its effectiveness in improving procedural competency among trainees.
