BACKGROUND AND AIM The aim of this study was to elucidate the risk of subsequent biliary malignancy in patients undergoing cyst excision for congenital choledochal cysts. METHODS A retrospective analysis of 94 patients who had undergone cyst excision for congenital choledochal cysts was conducted. The median age at the time of cyst excision and median follow-up time after cyst excision were 7...

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...

Post-cholecystectomy syndrome (PCS) is defined as a complex of heterogeneous symptoms, consisting of upper abdominal pain and dyspepsia, which recur and/or persist after cholecystectomy. Nevertheless, this term is inaccurate, as it encompasses biliary and non-biliary disorders, possibly unrelated to cholecystectomy. Biliary manifestations of PCS may occur early in the post-operative period, usu...

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...

BACKGROUND A meta-analysis was conducted to summarize the evidence from prospective cohort and case-control studies regarding the association between coffee intake and biliary tract cancer (BTC) and liver cancer risk. METHODS Eligible studies were identified by searches of PubMed and EMBASE databases from the earliest available online indexing year to March 2017. The dose-response relationshi...

Because of the increasing frequency of surgical procedures such as hepatic resection, partial liver transplantation, and laparoscopic cholecystectomy, the number of patients requiring biliary imaging has increased. In this report, magnetic resonance cholangiopancreatography findings of a case with an aberrant right posterior hepatic duct draining directly into the gallbladder, which was overloo...
