Inferior bile ductal carcinoma, Endoscopic ultrasonography
We report a case of curative excision for inferior bile ductal carcinoma suspected in anicteric
phase ultrasonographic screening and diagnosed in endoscopic ultrasonography in a 47-years-old
female patient with a chief complaint of right upper abdominal pain.
Endoscopic ultrasonography revealed an irregularly bordered 1.5 cm diameter tumor at the
inferior bile duct and carcinoma was diagnosed.
Endoscopic ultrasonography is useful as a method to confirm the presence of inferior bile ductal
carcinoma and also to discriminate it from other disturbances.
