Introduction: Mucosal healing has emerged as a desirable treatment goal in clinical practice for patients with Crohn's disease (CD). The aim of this study was to assess the relationship between endoscopic activity and the long-term prognosis of CD using simple endoscopic score for Crohn's disease (SESCD) and Rutgeerts' score. Methods: We conducted a cohort study in clinical practice at a single center. Among CD patients who underwent colonoscopy between July 2008 and June 2011 at our hospital, 131 patients with clinical remission were selected, and the patients were divided into 2 groups: a non-surgical group (n = 84) and a surgical group (n = 47). The primary endpoint of this study was to assess the associations between variables and clinical relapse after endoscopic procedures. The cut-off levels of SESCD or Rutgeerts' score for the prediction of relapse were also assessed in patients with clinical remission. Results: In the non-surgical group, SESCD and C-reactive protein at baseline were significantly higher in patients who had clinical recurrence than in patients who maintained remission. A factor of SESCD ≤2 was independently associated with sustained remission, even in patients with clinical remission. In the surgical group, patients with Rutgeerts' scores ≤1 had significantly prolonged clinical remission compared to patients with Rutgeerts' scores ≥3. Conclusion: A cut-off value of SESCD ≤2 and a Rutgeerts' score ≤1 enabled the prediction of long-term prognosis. These cut-off values could be used in clinical trials of endoscopic remission from the point of view of the clinical outcomes of CD.
