Résumé
The feasibility of magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD) using a neodymium magnet for colorectal tumors has not been evaluated. The aim of this study was to clarify the feasibility of MAG-ESD for colorectal tumors. This prospective trial was conducted at Yamashita Hospital. MAG-ESD was performed for 49 colorectal tumors. The magnetic anchor comprised an internal magnet attached to an endoclip with 3-0 silk. Both external and internal magnets were made using neodymium magnets. The feasibility of traction achieved using MAG-ESD, en bloc resection rate, complete en bloc resection rate, time required for preparation and attachment of the magnetic anchor, procedure time, rate of retrieval of magnetic anchors, and adverse events were evaluated. MAG-ESDs were successfully performed for 48 colorectal tumors except for a rectal case in which the internal magnet stuck to the endoscope. En bloc resections and complete en bloc resections were achieved in all cases. Attaching the magnetic anchor required a median of 8 min (range 3-37 min). Median procedure time was 76 min (range 28-283 min) and the magnetic anchors were retrieved in all cases without adverse events. MAG-ESD is feasible and safe in the colon and may facilitate the treatment of all difficult lesions. (UMIN000024100).

BACKGROUND
The feasibility of magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD) using a neodymium magnet for colorectal tumors has not been evaluated. The aim of this study was to clarify the feasibility of MAG-ESD for colorectal tumors.
METHODS
This prospective trial was conducted at Yamashita Hospital. MAG-ESD was performed for 49 colorectal tumors. The magnetic anchor comprised an internal magnet attached to an endoclip with 3-0 silk. Both external and internal magnets were made using neodymium magnets. The feasibility of traction achieved using MAG-ESD, en bloc resection rate, complete en bloc resection rate, time required for preparation and attachment of the magnetic anchor, procedure time, rate of retrieval of magnetic anchors, and adverse events were evaluated.
RESULTS
MAG-ESDs were successfully performed for 48 colorectal tumors except for a rectal case in which the internal magnet stuck to the endoscope. En bloc resections and complete en bloc resections were achieved in all cases. Attaching the magnetic anchor required a median of 8 min (range 3-37 min). Median procedure time was 76 min (range 28-283 min) and the magnetic anchors were retrieved in all cases without adverse events.
CONCLUSION
MAG-ESD is feasible and safe in the colon and may facilitate the treatment of all difficult lesions. (UMIN000024100).
