Invasives GI Practice Exam

In endoscopic assessment of inflammatory bowel disease, clinicians use scoring systems that quantify what the mucosa looks like during colonoscopy. The Mayo endoscopic subscore is used for ulcerative colitis and grades mucosal appearance on a 0–3 scale, where 0 is normal or inactive and 3 indicates severe disease with friability, ulcers, or spontaneous bleeding. The Simple Endoscopic Score for Crohn’s Disease (SES-CD) is used for Crohn’s disease and evaluates four features (ulcer size, proportion of ulcerated mucosa, proportion of involved mucosa, and presence of stringent stenosis) across five segments of the colon and ileum, giving a total score that reflects endoscopic activity.

These indices are widely accepted because they are validated, reproducible, and useful for tracking mucosal healing and response to therapy in trials and routine care. The other options are not endoscopic indices for IBD: APGAR is a newborn health score, Glasgow Coma Scale assesses level of consciousness after brain injury, and Child-Pugh evaluates liver disease severity.
