Several centers have identified colorectal cancer in patients with primary sclerosing cholangitis (PSC) and ulcerative colitis (UC) who have undergone orthotopic liver transplantation. Increased frequency of surveillance colonoscopy and prophylactic colectomy has been recommended. To address these concerns, we reviewed the posttransplantation experience with colorectal neoplasia in patients with PSC and UC at our institution. ⋯ The risk of colorectal neoplasia (dysplasia and cancer) after liver transplantation in patients with PSC and UC is clinically important. However, this risk had no impact on patient survival. Prophylactic proctocolectomy does not appear necessary, but annual surveillance colonoscopy is recommended.
