Achieving endoscopic remission has become one of the treatment goals in Crohn’s disease (CD) because recent studies have indicated that mucosal healing is associated with better CD outcomes after the initiation of medical treatment. Scoring the endoscopic disease severity is important, because endoscopy can objectively assess the severity of the disease. Crohn’s disease index of severity (CDEIS), the simple endoscopic score for Crohn’s disease (SES-CD), and the Rutgeerts postoperative endoscopic index are frequently used to assess endoscopic disease activity in CD. Changes in endoscopic scores are associated with clinical responses to medical treatments. CDEIS and SES-CD are clinically difficult to score. Although novel technologies to enable the diagnosis of small intestinal lesions have been developed, there have been few scoring systems to assess the severity of small intestinal lesions. The development of a simple score for both small and large intestinal lesions of CD is warranted.
