Figure 2. Radiological findings at cholelithiasis treatment 1 year earlier. Endoscopic retrograde cholangiopancreatography (ERCP) at electrohydraulic lithotripsy (A) and volume rendering image of drip infusion cholecystocholangiography (DIC-CT) before cholecystectomy (B) about 1 year earlier, showing no abnormality of the bile duct, such as stenosis. The ERCP shows stones at the orifice of and in the cystic duct. At DIC-CT, a transpapillary gallbladder stent is placed. The DIC-CT shows the anomaly of branching at the hilar bile duct: the right posterior sectoral duct and right anterior sectoral duct individually join the left hepatic duct in this order from upstream to form the common hepatic duct.
