Endoscopic findings of SSL and SSLD with NBI and BLI. (a) NBI magnification finding of SSL. Expanded crypt opening (ECO) (white arrows) and thick and branched vessels (TBV) (red arrows) are observed. (b) NBI magnification finding of SSL with dysplasia (SSLD). White dendritic changes (WDC) are white dendritic and serrated network or winding-line-like structures around crypts (white arrows). (c) NBI magnification finding of SSLD. Network vessels (NV) are meshed or spiral vessels with or without irregularity around crypts (white arrow). (d) BLI magnification finding of SSL. ECO (white arrows) and TBV (red arrows) are observed. (e) BLI magnification finding of SSLD. WDC is observed (white arrows). (f) BLI magnification finding of SSLD. NV is observed (white arrow).
