Brief Summary
This study is being done to: To attempt to increase the detection of precancerous colon tissue in patients with chronic ulcerative colitis and primary sclerosing cholangitis; To determine if an investigational scope that can look at the lining of the colon in different ways will help the doctor identify abnormal tissue in patients with chronic ulcerative colitis and concurrent primary sclerosing cholangitis; and To determine if this investigational scope can accurately detect precancerous or cancerous tissue in patients with chronic ulcerative colitis that are known to have had cancerous or precancerous tissue in the past.

Outcome Measures
Primary Outcomes (1)
Compare the dysplasia detection rate between scope modalities and biopsy type; surveillance or targeted biopsies in CUC patients with concurrent PSC.
Two years
Secondary Outcomes (1)
Assess the impact of patient related factors on the difference in dysplasia detection rate between while light colonoscopy and the AFI and NBI techniques in patients with CUC and concurrent PSC.
Two years.
Study Arms (2)
1
Patients with chronic ulcerative colitis and concurrent primary sclerosing cholangitis.
2
Patients with chronic ulcerative colitis and known dysplasia or cancer.
