Long-term Study in US Cystic Fibrosis Patients Receiving Digestive Enzyme Supplements to Assess Narrowing of the Large Intestine Causing Adverse Intestinal Symptoms (Fibrosing Colonopathy)

This is a long-term study in cystic fibrosis patients who are participating in the Cystic Fibrosis Patient Registry to assess the occurrence and risk factors for a rare bowel disorder called fibrosing colonopathy (narrowing of the large intestine). Patients will be followed at their regular clinical care visits over a 10-year period and approached if they develop symptoms of fibrosing colonopathy for collection and use of further detailed information.
