case_images: Contrast-enhanced computed tomography.. (a) Contrast-enhanced computed tomography revealed a gallbladder tumor (white arrow) and liver metastases (black arrow). (b) Bile ducts in the hilar region were obstructed by a gallbladder tumor (arrowhead).

case_images: Contrast-enhanced computed tomography (CE-CT) revealed a gallbladder tumor, liver metastases, and bile duct obstruction caused by a gallbladder tumor in the hilar region (Figure 1).
case_images: Endoscopic retrograde cholangiopancreatography.. Endoscopic retrograde cholangiopancreatography was performed. (a) A catheter was inserted into the bile duct (white arrow), and cholangiography was performed. When the bile duct was imaged, the pancreatic duct (white arrowhead) was also imaged at the same time. It showed that the bile duct and pancreatic duct merged outside the duodenal wall. (b) The area of bile duct obstruction was also confirmed (black arrow). The bile duct upstream of the obstruction was dilated (black arrowhead).

case_images: An area of bile duct obstruction was confirmed (Figure 2).
case_images: Transpapillary biliary stenting.. Two metal biliary stents without covers were placed transpapillary using the side-by-side method in the left and right intrahepatic bile ducts across the hilar biliary strictures.

case_images: Two metal biliary stents without covers were placed transpapillary using the side-by-side method in the left and right intrahepatic bile ducts across the hilar biliary strictures (Figure 3).
case_images: Histopathology of the gallbladder tumor obtained from biopsy during endoscopic retrograde cholangiopancreatography.. Atypical cells proliferate in tubular and vesicular shapes, indicating adenocarcinoma. (a) Hematoxylin and eosin stain (40x magnification). (b) Hematoxylin and eosin stain (100x magnification).
