Figure 2 The grasping forceps-assisted endoscopic resection procedure. A: Normal saline solution was injected into the submucosa around the lesion; B: A snare and grasping snare were both deployed through one of the scope’s two channels; C: The grasping snare was used to firmly grasp the elevated mucosa; D: The snare encircled the grasped mucosa; E: We ensured that the entire lesion was inside the snare, and then the resection was performed; F: After the resection, the mucosal defect was checked for residual tumour.
