The most commonly used clinical parameters for predicting a more serious course of CD are age of disease onset less than 40 years of age, perianal disease or the need for steroids during the first flare.[56 57] If a patient carries two out of the three parameters the positive predictive value for disabling CD in the future is approximately 90%. A history of smoking is another risk factor for complicated CD[58 59] and a faster rate of progression from diagnosis to first stricture.[60] Patients with active colonic or ileocolonic CD with deep and extensive mucosal ulcerations have a higher risk of subsequent surgical intervention.[61] Location of inflammation to the small bowel, rather than the colon, has also been identified as predictive of a patient's progression to stricturing disease and a higher rate of surgery.[60] The commonly used classification systems, in particular the Montreal classification,[45] only identify a stricture after it has become clinically apparent, and therefore using this classification to perform risk factor studies has substantial limitations
