What this trial studies

This study investigates the use of magnetic traction to assist in endoscopic submucosal dissection (ESD) for early gastric and colorectal cancers. ESD is a complex procedure that requires effective tissue traction to improve visibility and facilitate the dissection process. The magnetic retractor allows for dynamic manipulation of the tissue, potentially simplifying the procedure compared to traditional static traction methods. By enhancing the dissection technique, this approach aims to improve patient outcomes and reduce procedure time.

Who should consider this trial

Good fit: Ideal candidates include patients with superficial gastric or colorectal lesions scheduled for ESD.

Not a fit: Patients with contraindications such as cardiac pacemakers or metallic implants will not benefit from this study.

Why it matters

Potential benefit: If successful, this method could lead to more efficient and safer endoscopic treatments for early gastrointestinal cancers.

How similar studies have performed: While various traction methods have been explored, the use of magnetic traction in this context is a novel approach that has not been extensively tested in prior studies.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patient with superficial gastric or colorectal lesions, scheduled for endoscopic submucosal dissection (ESD).

Exclusion Criteria:

1. Patient who refused to participate
2. Other cases deemed by the examining physician as unsuitable for safe treatment

   The robotic magnetic countertraction system consist of a strong permanent magnet which always have a strong magnetic field in its surrounding. Therefore, we follow the MRI precautions for the strict safety measurement:
3. Patient who had a cardiac pacemaker.
4. Patient who had any metallic implant or device, such as drug pump, stent, etc.
5. Patient who has or had any metal fragments in eye or any other part of body, or had ever worked with metal.
