Figure 1 Representative images of visibility score for tumor margin. Visibility score was defined as following: score 4, excellent (easily detectable); score 3, good (detectable with careful observation); score 2, fair (hardly detectable without careful examination); score 1, poor (not detectable without repeated careful examination). WLI: White light imaging; TXI: Texture and color enhancement imaging; NBI: Narrow band imaging; CE: Chromoendoscopy.
