Bile duct cancer is subdivided according to the anatomic location of origin into intrahepatic and extrahepatic cholangiocarcinoma, gallbladder cancer, or ampulla of Vater cancer. While biliary tract cancer is uncommon in Western countries, the incidence is relatively high in Asia, including Japan, and Latin America. However, in biliary tract cancers, the incidence of intrahepatic cholangiocarci...

Interventional radiologists fi rst became involved in the management of malignant obstruction of the biliary tree in the late 1960s, when Kaude et al. introduced nonsurgical biliary drainage. Since then, improved diagnostic imaging techniques, significant developments in interventional radiology, and the results of clinical trials have revolutionized and clearly defi ned the role of percutaneou...

Biliary tract cancers are rare but fatal malignancies, with increasing incidence in Shanghai, China. Gallstones, the primary risk factor for biliary tract cancer, typically result from oversaturation of cholesterol in bile. We examined the association of five variants in three lipid metabolism-related genes (CETP, ABCG8 and LRPAP1) and biliary tract cancers and stones in a population-based case...

Bile is normally sterile. Bactibilia occurs when bile flow is impaired and bacteria gain access to the biliary duct by the papilla or portal circulation. Bile duct obstruction leads sequentially to increase in intra biliary pressure, infection of bile, cholangiovenous and cholangiolymphatic reflux leading to bacteremia [1-3]. The bacteria described commonly in biliary tract infections include E...

OBJECTIVE The purpose of this essay is to illustrate the imaging findings of congenital cystic lesions of the biliary tract. CONCLUSION Congenital cystic lesions of the biliary tract include ductal plate malformations and choledochal cysts and can be recognized with characteristic imaging findings and basic knowledge of the embryologic development of the biliary tree.

OBJECTIVE The diagnosis of cholecystitis or biliary tract disease in children and adolescents is an uncommon occurrence in the emergency department and other acute care settings. Misdiagnosis and delays in diagnosing children with cholecystitis or biliary tract disease of up to months and years have been reported in the literature. We discuss the technique and potential utility of point-of-care...

Malignancies of the biliary tract include cholangiocarcinoma, gallbladder cancers and carcinoma of the ampulla of Vater. Biliary tract adenocarcinomas are the second most common primary hepatobiliary cancer. Due to their slow growing nature, non-specific and late symptomatology, these malignancies are often diagnosed in advanced stages with poor prognosis. Apart from incidental discovery of gal...

OBJECTIVE To investigate the role of biliary tract disease in patients with acute non-A-E hepatitis. DESIGN Prospective study. SETTING Infectious diseases unit, government hospital, Hong Kong. PATIENTS Sixty-one consecutive patients, admitted with the diagnosis of acute hepatitis and negative hepatitis serology for hepatitis A, B, C, D, and E virus. MAIN OUTCOME MEASURES Abdominal ultra...

Minimally invasive percutaneous techniques, staged as part of the combined treatment high stricture complications biliary tract, demonstrated efficiency in short term. On other hand, use self-expanding nitinol stents a definitive for non-tumor tract long-term life prognosis cannot be recommended routine intervention. The these cases can only justified absence alternative options, subject to fre...

INTRODUCTION Percutaneous nephrolithotomy is generally considered a safe option for the management of large complex or infectious upper urinary tract calculi. Biliary tract injury is a rare and potentially serious complication of percutaneous nephrolithotomy that can even lead to mortality, especially in cases where biliary peritonitis develops. All reported cases of biliary tract injury have b...
