INFORMATION AND REFERENCES
The endoscopic Mayo Score (Mayo endoscopic subscore) evaluates ulcerative colitis stage, based only on endoscopic exploration (subscore "Endoscopic findings" of the Full Mayo Score) and can be used on its own (1).
The following table shows the decoding for endoscopic findings, with some example images.
