ClinConnect Summary

This clinical trial is studying a new tool called the MAG-ESD system, which uses magnets to help doctors perform a procedure known as endoscopic submucosal dissection (ESD). ESD is a technique used to remove early-stage cancers from the stomach and colon while preserving the organ. This trial aims to see if the magnetic system can make the procedure easier and safer for patients by providing better control and visibility during the surgery.

To participate in this trial, patients should be between the ages of 65 and 74 and have superficial lesions in the stomach or colon that need treatment. However, some patients may not be eligible if they have certain medical devices, like a pacemaker, or if they have metal fragments in their body. Those who join the study can expect to have their procedure performed using the new magnetic system, and the research team will closely monitor their safety and the effectiveness of this innovative approach.

Eligibility 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.
