Proctocolectomy for colon cancer associated with ulcerative colitis a few months after living donor liver transplantation for primary sclerosing cholangitis: report of a case.

Colorectal cancer (CRC) frequently develops in patients with ulcerative colitis (UC). We report a case of CRC treated successfully by proctocolectomy 8 months after living donor liver transplantation (LDLT) for primary sclerosing cholangitis (PSC). The lesion was detected early, probably as a result of colonoscopic surveillance after LDLT. Thus, patients with a long history of UC, who undergo LDLT for PSC, should be followed up with regular surveillance colonoscopy. Moreover, surgery, such as radical resection of the colon and rectum should be performed without delay, even shortly after LDLT. To our knowledge, this is the first report of a patient undergoing proctocolectomy after LDLT.
