Ursodeoxycholic acid combined with percutaneous transhepatic balloon dilation for management of gallstones after elimination of common bile duct stones

Figure 1 Computed tomography scan and cholangiography showing filling defect in the common bile duct and gallbladder (white arrow). Dilation of the common bile duct and cystic duct was detected. A and B: Ultrasonography, enhanced computed tomography, magnetic resonance cholangiopancreatography, or cholangiography was carried out to determine the diagnosis of stones; C: Advancing cholangiography was performed to detect the number, size, and location of stones.
