The Rutgeerts score after Crohn's resection
What is the Rutgeerts score and how does it guide management after CD resection
What is known
- The score was designed to predict clinical recurrence risk after ileocolonic resection from early endoscopic findings at the anastomosis and neoterminal ileum. 1,2
- Therapy is modified based on post-operative endoscopic findings to reduce clinical and surgical recurrence. 2
- The i2 category has heterogeneous recurrence risk, prompting a modified score (i2a anastomotic-confined vs i2b >5 ileal aphthae). 1
What is unknown / caveats
- A modified rutgeerts score separating anastomotic from ileal i2 lesions did not change determination of recurrence or need for intervention 1
- Ileal vs anastomotic lesion location did not impact recurrence rate in i2 patients 3
- Applies specifically to ileocolic/ileocolonic resection with anastomosis, not other Crohn's segments
- Interobserver variability in scoring is documented 4,5
- Whether subdividing the i2 category meaningfully alters management remains contested in the retrieved excerpts.

⚠ Required context not in this corpus (moderate). WITHOUT prophylaxis, ANY endoscopic recurrent lesion in the neoterminal ileum is seen in ~73% within 1 year and ~85% by 3 years of ileocolic resection (Rutgeerts 1990, PMID 2394349). The baseline is the majority, not a minority. (Denominator is any lesion, not a >=i2 cut.)
Why this matters: Understating the untreated recurrence rate makes declining postoperative prophylaxis look reasonable when the expected course is recurrence in most patients.
