Combined common bile duct and gastric outlet obstruction demonstrated during hepatobiliary scintigraphy.

A 64-year-old man presented with jaundice. Hepatobiliary imaging using 99mTc-DISIDA revealed complete hepatobiliary tract obstruction with a photopenic area corresponding to a dilated gallbladder and a large photopenic region corresponding to a distended stomach as a result of gastric outlet obstruction. At surgery, carcinoma of the head of the pancreas was found to be the cause of the combined common bile duct and gastric outlet obstruction.
