Figure 2 ESD of colorectal neoplasms. (A) Chromoendoscopic view with indigo carmine dye showing demarcation of the margin of an LST-NG-F, intramucosal adenocarcinoma, 2.5 cm in size, located in the ascending colon. (B) Submucosal injection at the oral margin of the lesion with the retroflexed position of the endoscope. (C) Initial mucosal incision at the oral margin of the lesion with the retroflexed position of the endoscope. (D) Submucosal injection at the anal margin with the straight position of the endoscope. (E) Mucosal incision at the anal margin and extension of the incision in a circumferential manner around the lesion with the straight position of the endoscope. (F) Repetition of submucosal injections from the exposed submucosal layer and dissection of the submucosal connective tissue until the lesion detached. (G) Artificial ulcer after removal. (H) Complete resection of the lesion in one piece. Clinical Gastroenterology and Hepatology 2007 5, 678-683DOI: (10.1016/j.cgh.2007.01.006) Copyright © 2007 AGA Institute Terms and Conditions
