The patient had undergone a normal colonoscopic examination 18 months prior to this admission, and there was no history of lower abdominal pain or hematochezia.

Laboratory evaluation showed hemoglobin, 12.3 gm/dL; albumin, 3.5 gm/dL; total bilirubin, 11.2 mg/dL; direct bilirubin 7.8 mg/dL; alkaline phosphatase, 204 IU/dL; aspartate transaminase,35 IU/dL; and alanine tranaminase 48 IU/dL. Prothrombin time was 13.6, and INR 1.2. Computerized tomography of the abdomen at admission revealed intrahepatic biliary ductal dilatation, proximal common bile duct dilation to 1.2 cm, and gallbladder wall thickening. No mass lesion was identified. A percutaneous transhepatic cholangiogram was performed.
