Endoscopic ultrasound for cholangiocarcinoma re-evaluation after Wallstent® placement

Abstract

Together with methods as magnetic resonance imaging (MRI) cholangiography and endoscopic retrograde cholangiography (ERC), endoscopic ultrasound (EUS) readily visualizes common bile duct (CBD) and allows the diagnosis of bile duct masses or strictures (1). Once a Wallstent has been placed, re-evaluation of the bile duct and stent patency may be difficult. We present the case of a patient with a Klastkin tumor to show the utility of EUS in this setting.
