Artificial wounds detected from endoscopy. (a) Artificial ulcer remained from ESD in the control group. (b) The ulcer bed 2 weeks later in the control group. (c) The wound of ESD in the experimental group. (d) The ulcer bed 2 weeks later in the experimental group. The wounds in the experimental group showed less severity than the control group when detected by endoscopy 2 weeks later. ESD, endoscopic submucosal dissection.
