IBD IBD Disease Monitoring and Activity Assessment 3

Question 1

After escalating IBD therapy, the treat-to-target approach recommends endoscopic reassessment within what timeframe?

Accepted Answer

3–6 months

Answer

Endoscopic reassessment 3–6 months after a treatment change allows adequate time for mucosal healing to occur while avoiding prolonged delays that permit ongoing inflammation-driven damage.

Question 2

In ulcerative colitis clinical trials, mucosal healing is most commonly defined as a Mayo endoscopic subscore of:

Accepted Answer

0 or 1

Answer

Mucosal healing in UC trials is typically defined as a Mayo endoscopic subscore of 0 (normal/inactive) or 1 (mild erythema with decreased vascular pattern), representing the threshold for acceptable endoscopic response.

Question 3

MRI enterography is preferred over CT enterography for monitoring Crohn's disease activity primarily because it:

Accepted Answer

Avoids ionizing radiation while providing equivalent soft tissue detail

Answer

MRI enterography eliminates ionizing radiation exposure, which is critical for young Crohn's disease patients who require repeated imaging over a lifetime, while providing superior soft tissue contrast for detecting mural and extramural disease.

Question 4

The Simple Endoscopic Score for Crohn's Disease (SES-CD) evaluates all of the following parameters EXCEPT:

Accepted Answer

Bowel wall thickness

Answer

The SES-CD assesses ulcer size, ulcerated surface, affected surface, and presence of narrowing (stenosis) at endoscopy; bowel wall thickness is a cross-sectional imaging parameter assessed by MRI or CT, not endoscopy.

Question 5

Current guidelines recommend initiating colorectal cancer surveillance colonoscopy in patients with extensive ulcerative colitis after what duration of disease?

Accepted Answer

8–10 years after symptom onset

Answer

CRC surveillance colonoscopy should begin 8–10 years after symptom onset in patients with extensive UC, as cumulative colonic inflammation progressively increases colorectal cancer risk over this timeframe.
