Contrast cholangiogram via dual, split lumen catheter. The efferent catheter limb drapes the biliary confluence (small arrow), and the afferent catheter limb is in the duodenal lumen (round tip arrow). Normal caliber of the intrahepatic radicles (large arrow) with contrast within the duodenum (long arrow) is noted indicating biliary decompression and bile deposited in the bowel.
