ABSTRACT

Objective:

To investigate the feasibility of magnetic anchor technique for endoscopic submucosal dissection (ESD) in the treatment of early esophageal cancer.

Methods:

A self-designed magnetic anchoring device (including an anchor magnet and a target magnet) was used to perform ESD on the hypothesized esophageal lesion mucosa of six isolated esophagus of Beagle dogs. The feasibility and convenience of the operation was evaluated.

Results:

ESD of 6 isolated esophagus of dogs was successfully completed. Through adjusting the position of anchor magnet, the pulling direction and force of the target magnet on the mucosa could be flexibly controlled, the mucosal peeling surface was fully exposed, and tissue tension was provided to ensure the smooth removal of the diseased mucosa. The entire operation was smooth, and the target magnet was conveniently retained. No target magnet slippage or mucosal laceration occurred during the operation.

Conclusion:

The magnetic anchor technique is safe and feasible for the ESD, effectively pulling the diseased mucosa in treatment of early esophageal cancer, which can greatly improve the endoscopic operation experience.
