    The incidence and mortality rates of colorectal cancer in China are rising, highlighting the need for improved endoscopic techniques.

  • 2

    Conventional endoscopic submucosal dissection (ESD) faces challenges due to lack of reverse traction, complicating procedures in the colorectal region.

  • 3

    Magnetic hydrogel, a novel adjunct to ESD, can be injected easily and eliminates the need for repeated endoscope withdrawal during procedures.

  • 4

    In experiments, magnetic hydrogel-assisted ESD demonstrated improved lesion resection speed and reduced intraoperative complications compared to conventional ESD.

  • 5

    The interaction between magnetic hydrogel and external magnets enhances traction and control during ESD, potentially improving surgical outcomes.
