The first description of percutaneous biliary drainage in the United States appeared in 1965 [1]. The percutaneously placed catheters were left in the obstructed biliary tract for drainage for up to 5 days. Since then, biliary drainage techniques have advanced substantially, and options have proliferated. Now, the nonsurgical palliation of malignant biliary obstruction, accomplished either endo...
BACKGROUND Salmonella enterica serotype Typhi can colonize and persist in the biliary tract of infected individuals, resulting in a state of asymptomatic chronic carriage. Chronic carriers may act as persistent reservoirs of infection within a community and may introduce infection to susceptible individuals and new communities. Little is known about the interaction between the host and pathogen...
Trends in biliary tract cancer incidence rates have increased in Shanghai, China. These trends have coincided with economic and developmental growth, as well as a shift in dietary patterns to a more Westernized diet. To examine the effect of dietary changes on incident disease, we evaluated associations between diet and biliary tract cancers amongst men and women from a population-based case-co...
(18)F-Labeled fluorodeoxyglucose positron-emission tomography (FDG-PET), a rapidly evolving functional imaging modality, has recently been shown to be useful in the diagnosis and staging of various malignant tumors due to focal uptake of FDG-labeled glucose in malignant cell populations. However, the role of FDG-PET in the diagnosis and staging of biliary tract cancer is still controversial and...
To reevaluate the current features of spontaneous internal biliary fistulas, we reviewed 1,929 consecutive patients who had been treated for biliary tract diseases during the recent 12-year period. Thirty-three patients had internal biliary fistulas and the incidence was 1.9%. Of 33 patients, 20 were women and 13 were men with the average age 63 years, and their mean duration of illness was 4 y...
Chronic pancreatitis can be complicated by benign biliary stricture in about 5-40% of the patients[1]. The severity of this biliary narrowing varies with patients having a wide range of presentation ranging from asymptomatic elevation of liver enzymes to deep jaundice and cholangitis. It is important to treat biliary obstruction, as long standing biliary stricture can lead on to secondary bilia...
Determination of the minimum inhibitory concentrations of rifamide necessary to inhibit organisms isolated from the biliary tract showed that the organisms were almost invariably sensitive to concentrations which are readily attainable in the biliary tract. Three cases of severe acute inflammation of the biliary tract were treated and this led to rapid clinical improvement. In 61 patients under...
Biliary tract carcinoma is a relatively rare tumor with a poor prognosis. Surgical resection is the only potential cure. However, the efficacy of chemotherapeutic agents is disappointing in advanced or recurrent cases. Gemcitabine (GEM) appears to be one of the most promising chemotherapeutic agents in biliary tract carcinoma, and ribonucleotide reductase subunit M1 (RRM1) plays an important ro...
Several infectious agents are considered to be causes of cancer in human, mainly hepatitis B and C viruses, high-risk human pailloma viruses, Helicobacter pylori, Clonorchis sinensis, and Opisthorchis viverrini. Here we described the evident research and the association between Helicobacter spp. and biliary tract cancer particularly cholangiocarcinoma (CCA). Global epidemiological studies have ...
