Characteristics of early gastric tumors with different differentiation and predictors of long-term outcomes after endoscopic submucosal dissection

Figure 1 Endoscopic submucosal dissection process. A: 0-IIa + 0-IIc lesion in the greater curvature of the antrum (white light), the lesion flattened after inflation; B: NBI + ME: DL (+), the lesion elevation was evident after inspiration; C: Indigo carmine staining; D: Peripherally marked lesion; E: The surrounding mucosa was incised; F: Submucosal dissection; G: The resected wound; H: Fixed specimen.

Figure 2 Kaplan-Meier curves showed overall survival and disease-free survival during the follow-up period. A: Overall survival; B: Disease-free survival (DFS); C: DFS based on complete resection; D: DFS based on white moss; E: DFS based on multiple primary cancer; F: DFS based on lesion differentiation. LGIN: Low-grade intraepithelial neoplasia; HGIN: High-grade intraepithelial neoplasia.
