The Efficacy of Endoscopic Submucosal Dissection of Type I Gastric Carcinoid Tumors Compared with Conventional Endoscopic Mucosal Resection
Figure 2
(a) An approximately 1 cm, round, slightly elevated subepithelial lesion with a central hyperemic depression was observed at the anterior wall side of the lower body. (b) The marking was performed using an argon plasma coagulator. (c) A circumferential mucosal incision was performed after a submucosal injection. (d) A submucosal dissection being performed. (e) A large artificial ulcer created by endoscopic submucosal dissection for a type I gastric carcinoid tumor was observed. (f) Endoscopic en bloc resection was achieved. (g) Histologic findings (hematoxylin and eosin (H&E) stain, ×40) showed complete resection: negative lateral and negative deep resection margin.
