Figure 6 Endoscopic view of each step of endoscopic submucosal dissection using the clutch cutter for granular and homogeneous type laterally spreading tumor of the ascending colon. A: Several points along the contour of the lesion are marked with a coagulation current; B: Submucosal injection of hyaluronic acid solution; C: The targeted mucosa is grasped outside the marking points for fixation prior to first mucosal incision; D: First mucosal incision; E: The deep submucosal layer is gradually dissected using the clutch cutter from the muscularis propria; F: The tumor is completely resected; G: The resected specimen shows en-bloc resection of the tumor; H: Cross-section of the resected specimen showing R0 resection.
