Endoscopic resection of colorectal laterally spreading tumors: Clinicopathologic characteristics and risk factors for treatment outcomes

Figure 1 Laterally spreading tumors treated with endoscopic submucosal dissection. A: 4.5 cm laterally spreading tumors in the ascending colon; B: Following injection of the lesion; C: Full circumstantial mucosal resection was performed; D: The mucosal wound after removal of the lesion; E: The wound was closed with titanium clips; F: The resected specimen.
