This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing a new magnetic retraction system to help surgeons during endoscopic submucosal dissection (ESD)—a minimally invasive procedure used to remove early-stage cancers from the stomach or colon. Instead of using clips and strings inside your body (which can be cumbersome and block the surgeon's view), the magnetic retractor is controlled from outside your body, keeping your internal workspace clearer and giving your surgeon better visibility and control during the procedure.
Current traction techniques during ESD require multiple clips and instruments inside the body, which makes the procedure more complex, longer, and harder for surgeons to see clearly—especially with flat or large lesions. This new magnetic approach is designed to simplify the procedure, reduce operating time, and improve outcomes by providing better visualization and steadier traction from outside the body.

If you enroll, you will receive your endoscopic submucosal dissection procedure with the aid of the new magnetic retraction system. The surgery itself will proceed as your doctor normally would perform it, but with the added benefit of external magnetic guidance to help position and hold the tissue during the removal. You will be one of approximately 20 patients in this pilot study, which helps researchers evaluate whether this new magnetic approach is safe and effective.
