Prevalence and Long‐term Outcome of Sub‐clinical Primary Sclerosing Cholangitis in Patients with Ulcerative Colitis

Primary sclerosing cholangitis (PSC) is closely associated with inflammatory bowel disease, particularly ulcerative colitis (UC), with an increased risk of biliary and colorectal malignancy. We sought to clarify the prevalence, characteristics and long‐term outcome of sub‐clinical PSC diagnosed by magnetic resonance cholangiogram (MRC) in patients with UC and normal liver biochemistry, with or without colorectal dysplasia (CRD).
