Post-ERCP Cholangiogram

This is a cholangiogram image of the patient who had undergone ERCP for cholelithiasis and common bile duct obstruction. On pre-ERCP images the level of the bile duct obstruction was clearly visible.

The above images were taken by injecting contrast through the external biliary drain. Now, you can see the contrast filling the biliary ducts and duodenum (labeled CBD and duodenum respectively).

Subsequently, the external drain was removed and the patient underwent open cholecystectomy.
