  • CBC: 16/12.4/35.1/281
  • LFT: AST 281, ALT 302, AP 264, T.bili 22.1, D.bili 16.8


  • RUQ US: Biliary sludge, no stones, no GBW thickening, no pericholycystic fluid
  • ERCP: 3cm stricture of distal CBD, biopsies taken


51AAM w/DM, HTN, sarcoidosis with 3wks painless jaundice. Obstructive pattern along with only modest elevation of liver enzymes suggests the obstruction is likely extrahepatic which was supported by ERCP finding of a distal CBD stricture. Patient has no history of prior instrumentation to cause iatrogenic stricture, and while sarcoidosis is associated with cholestatic complications (portal granulomas), pathology from biopsy showed papillary adenocarcinoma. The patient was scheduled for surgery with a plan for initial laparoscopic survey of the abdomen followed by Whipple if no evidence of widespread disease.




3cm stricture of distal CBD



Filling defect in the common bile duct with marked dilatation of the common duct and intrahepatic ducts.
Findings may reflect an intraluminal mass or stone.

CT Abdomen/Pelvis

Common bile duct stent present
Expected air in the intrahepatic biliary tree and mild biliary ductal dilatation
