Modified Rutgeerts Score

Endoscopic post-operative recurrence after ileocolonic resection.

Crohn'sPost-operativeEndoscopicValidated score

Clinical indication

Endoscopic recurrence in the neoterminal ileum after ileocolonic resection, conventionally assessed six to twelve months postoperatively, to guide prophylaxis and monitoring.

What is scored

The calculator collects 1 item:

Any item left blank stops the score being calculated — an incomplete form never reports as remission.

Interpretation

i0 - i1No recurrence
i2aIntermediate
i2b - i4Recurrence

Bands as implemented in IBD Care. A band is a description of the score, not an instruction.

Limitations

Applies only after ileocolonic resection with anastomosis. The i2 category is the contested one — the modified score splits it into i2a (anastomotic lesions only) and i2b (ileal lesions), and the prognostic meaning of i2a remains debated. Findings confined to the anastomosis may reflect ischaemia or suture effects rather than recurrent Crohn's disease.
