Abstract/OtherAbstract:
BACKGROUND AND STUDY AIMS: Bile duct varices are not a well-recognized feature of portal venous obstruction. The aim of the present study was to describe the clinical and endosonographic features of biliary involvement in patients with extrahepatic portal venous obstruction (EPVO). PATIENTS AND METHODS: A retrospective study was conducted of the clinical features, outcome, and endosonographic findings (using Olympus EUM-3 or EUM-20 probes) in 21 patients with EPVO and endosonographic features of biliary varices. Biliary varices were defined as multiple, large, serpiginous, anechoic vascular channels in and/or surrounding the extrahepatic biliary tracts. RESULTS: Biliary varices have not previously been visible using conventional imaging methods (computed tomography and ultrasonography). They were identified using EUS in the wall of the common bile duct in 16 patients (76%), surrounding the common bile duct (CBD) in 11 patients (52%), and in the gallbladder in nine (43%). The varices were the cause of obstructive jaundice in three of the 21 patients (14%), but only when they were in the wall of the CBD. Two of these patients were treated using portosystemic shunting, and the other received a biliary endoprosthesis. The EUS examination also provided evidence of unrecognized pancreatic or biliary tumors in three other patients with EPVO of undetermined origin. CONCLUSIONS: EUS can serve to diagnose biliary varices in patients with EPVO and jaundice. Although biliary varices are mainly asymptomatic, they may cause obstructive jaundice when they are located in the wall of the CBD. EUS can also detect unrecognized malignant tumors in patients with EPVO of undetermined origin.
