Figure 3 The operational process of magnetic anchor technique-assisted endoscopic submucosal dissection. A: Esophageal mucosa was examined by gastroscopy; B: The putative diseased mucosa was marked with the electric knife; C and D: The target magnet and mucous membrane were sucked up, the operating field was exposed, and the direction and tissue tension were changed as the anchor magnet position was changed; E: The marked mucosa was completely exfoliated; F: The mucous membrane that has been removed.
