A: Endoscopic images of the lesion before endoscopic submucosal dissection (ESD); B: Magnifying endoscopy with narrow-band imaging images of the lesion before ESD; C: Endoscopic images after ESD; D: Photographs of longitudinal sections of the gross appendix specimen; E: Endoscopic images of longitudinal sections of the gross appendix specimen; F and G: Magnifying endoscopy with narrow-band imaging images of longitudinal sections of the gross appendix specimen; H: Endoscopic images 1 year after laparoscopic appendectomy showed no signs of recurrence.
