Crohn’s disease is a form of inflammatory bowel disease, or IBD. Nearly half of all Crohn’s disease patients will need to have surgery within ten years of being diagnosed. However, surgery is not a cure. Crohn’s disease can come back (recur), and up to 25 percent of patients will need another surgery within 5 years of their first surgery. Regular colonoscopy can help catch a recurrence of Crohn’s Disease before symptoms come back. Taking certain drugs after surgery for Crohn’s disease can reduce the risk of symptoms returning, but some of these drugs have side effects.
