Background:
Few data exist of prospective parallel scoring of the validated endoscopic scores in Crohn's disease (CD), Crohn's Disease Index of Severity (CDEIS), and Simple Endoscopic Score for Crohn's Disease (SES-CD).
Methods:
Both the CDEIS and the SES-D were scored immediately after each endoscopy of 86 CD patients referred for ileocolonoscopy in a cross-sectional study. Furthermore, after CD therapy, 32 CD patients underwent a follow-up endoscopy with scoring of the CDEIS and SES-CD. Endoscopic scorings were graded as inactive, mild, moderate, or severe. Clinical activity was assessed with the Crohn's Disease Activity Index (CDAI) and serum C-reactive protein (CRP) was measured.
Results:
The SES-CD correlated with the CDEIS significantly (Spearman's r = 0.938, P < 0.0001). Weaker correlations were detected between the SES-CD and the CDAI (r = 0.473) or CRP (r = 0.525, both P < 0.0001). Grading of SES-CD from inactive to severe correlated significantly with grading of the CDEIS (r = 0.859, P < 0.0001). Changes between baseline and follow-up endoscopy scores correlated significantly (r = 0.828 between delta-CDEIS and delta-SES-CD, P < 0.001), but failed to correlate with delta-CDAI or delta-CRP (all P > 0.05).
Conclusions:
Both validated endoscopic scores, the CDEIS and SES-CD, and their changes during CD therapy demonstrated a close correlation. For scoring of endoscopic activity in clinical routine, the SES-CD could replace the CDEIS.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
