Impact of gastric neoplasms location on clinical outcome of patients treated by endoscopic submucosal dissection

Figure 3 Illustrative pictures of endoscopic submucosal dissection in the upper-middle third of the stomach. A: A 33-year-old woman presented with a flat-type lesion (0-IIb) in the upper-middle third of the stomach (gastric body); B: Markings were placed for endoscopic submucosal dissection. Mucosal incision was started at the distal margin of the lesion; C: Mucosal incision; D: Submucosal layer dissection; E: Complete tumor resection was achieved en bloc; F: Histological analysis of the endoscopic submucosal dissection specimen that revealed predominantly undifferentiated (diffuse) mixed-type adenocarcinoma.
