Feasibility and safety of endoscopic submucosal dissection for lower rectal tumors with hemorrhoids

Figure 3 Endoscopic submucosal dissection for lower rectal lesions with hemorrhoids. A, B: The laterally spreading tumor granular type (nodular mixed type) with hemorrhoids located at the lower rectum expanding to half of the lumen; C: The ulcer floor after endoscopic submucosal dissection (ESD); D: Hemorrhoid was partially improved (1 year after ESD). Yellow arrow indicates remnant hemorrhoids and red arrow indicates ESD scar.
