MAG-ESD, controlled by an extracorporeal electromagnet, facilitates the standard ESD procedure by providing this retraction capability using magnets.
According to the researchers, the MAG-ESD technique allowed for excellent visualization of the submucosal layer because it made suitable tissue tension possible. This simplifies a gastric ESD, even for large lesions in the gastric body.
The study showed that the long-term exposure to the magnetic field did not cause any unwanted physiological or mental effects. Furthermore, no delayed complications or allergies related to the stainless steel magnetic anchor were observed. All the tumors were resected en bloc, without any perforation or severe uncontrollable bleeding.
