Confirmation of anomalous biliary anatomy. Transhepatic cholangiogram. Yellow arrows show endoscopic placed stent in right anterior sectoral duct. There is no contrast in the anterior sectoral duct or its branches. Black arrows show contrast in the posterior sectoral duct and filling of posterior duct and branches. White arrow shows extrahepatic pigtail placed catheter. Red arrow shows extravasation of bile. This cholangiogram demonstrates that the anterior and posterior ducts are not in continuity.
