Correlation between the endoscopic and histologic score in assessing the activity of ulcerative colitis

In routine practice, scoring of activity and severity of ulcerative colitis is based on combined clinical and endoscopic assessment. Histology also allows sensitive scoring of ulcerative colitis activity. The correlation between endoscopy and histology has not been investigated thoroughly. It is still unknown how well they correlate and whether scoring both endoscopy and histology better reflects the true disease activity than each of the methods separately.status: publishe
