Representative images for quality of post-ESD ulcer scar at 8 weeks after ESD: flat scar (a), intermediate scar (b), and nodular scar (c). Flat scars were defined as lesions with smooth mucosal healing without any elevation; nodular scars exhibited one or more elevated nodular components at the ulcer base or margin; intermediate scars were characterized by ambiguous features that did not fully meet the criteria for either flat or nodular types. ESD, endoscopic submucosal dissection.
