Magnetic hydrogel-assisted endoscopic submucosal dissection of large intestine in vitro animal experimental study.

ABSTRACT:

Background

Magnetic anchor-guided endoscopic submucosal dissection (MAG-ESD) has significant advantages in the treatment of difficult lesions (Mortagy et al. in World J Gastroenterol 23:2883-2890, 2017). However, the main problem of MAG-ESD is that the placement of the magnetic anchor in vivo often requires the withdrawal and reinsertion of the endoscope, which prolongs the operation time (Zhang et al. in Tech Coloproctol 27:679-683, 2023). We introduced a novel technique, magnetic hydrogel-assisted ESD, and compared it with conventional ESD to explore its advantages and disadvantages.

Methods

We uniformly configured 0.5% sodium alginate (Sanchez-Ballester et al. in Carbohydr Polym 270:118399, 2021) (SA) solution, 1% CaCl₂ solution and nano-Fe₃O_4</
