Question: A 63-year-old man was referred for outpatient endoscopic ultrasound examination (EUS) to evaluate a pancreatic cyst. His past medical history was notable for ulcerative colitis requiring colectomy and primary sclerosing cholangitis (PSC) cirrhosis requiring cadaveric liver transplantation 4 years earlier. At that time, he underwent a split liver graft (right lobe trisegmentectomy) transplant surgery with choledochoduodenostomy anastomosis. Pathologic examination of the liver explant revealed biliary cirrhosis, severe PSC, portal vein thrombosis, and grade I biliary intraepithelial neoplasia of the common hepatic duct without malignancy.
