Multiple biliary papillomatosis involves an epithelial field change of the intrahepatic and extrahepatic portions of the biliary tree. Pathologically it is benign, occasionally with dysplasia, but the clinical behavior is regarded as having a low-grade malignant potential. Such malignancy is rare but the prognosis is poor if it is impossible to remove the tumor completely. Here, we report one case of multiple biliary papillomatosis in the biliary tree.

Biliary self-expandable metal stents (SEMS), a group of non-vascular stents, have been used in the palliative management of biliary obstruction around the world. However, there are still unmet needs in the clinical application of biliary SEMS. Comprehensive understanding of the SEMS is required to resolve the drawbacks and difficulties of metal stent development. The basic structure of SEMS, including the materials and knitting methods of metal wires, covering materials, and radiopaque markers, are discussed in this review. What we know about the physical and mechanical properties of the SEMS is very important. With an understanding of the basic knowledge of metal stents, hurdles such as stent occlusion, migration, and kinking can be overcome to develop more ideal SEMS.

Background: Magnetic resonance pancreatography (MRCP) is a safe noninvasive imaging technique that has proven to be accurate in the diagnosis of biliary tract diseases. Objective: To evaluate the role of MRCP in diagnosis of the anatomic variants of the biliary tree. Subjects and method: A retrospective study (from Augusts 2003 to April 2006, at Gia Dinh People Hospital) was conducted in 147 MRCP. All of anatomic variants of the biliary tract were classified. Results: MRCP had the sensitivity of 85.1%, the specificity of 92.1%, and the accuracy of 89.2%. Anatomic variants of the biliary tract included: type I (65%), type II (33.6%), type III (0%), type IV (1.4%). The anatomic variants of extrahepatic biliary tract that had high risk of damaged bile duct during laparoscopic cholecystectomy such as ectopic of right posterior hepatic duct (18.2%) and abnormal of junction of cystic duct and hepatic commune bile duct (2.9 - 44.6%). Conclusions: In this study, MRCP showed the modality of choices in the evaluation of hepatobiliary diseases and the anatomic variants of the biliary tree. MRCP helped the surgeons to avoid the injury of bile ducts during the operations.
