To investigate bile culture and susceptibility test in patients with malignant biliary obstruction (MBO) or relation between bile, portal vein or vein culture and biliary infection. Culture of the organism is recognized as the "gold standard" for diagnosis of infection. Our research may be one of the first research on culture and susceptibility test in patients with MBO. The results of the trial research will be benefit to experiential therapy of MBO with biliary infection.
We will obtain bile sample for culture and susceptibility test after PTCD.

The purpose of this study is to compare the duration of stent patency of a covered vs. an uncovered biliary self-expandable metal stents (SEMS) placed to relieve biliary obstruction in pat...
Malignant obstructive jaundice is a common complication of advanced stage cholangiocarcinoma, GB cancer, and pancreatic cancer. In biliary stricture by malignancy, biliary drainage with pl...
Only a small proportion of patients with biliary obstruction caused by hepatopancreatobiliary malignancies are suitable for surgical resection. Therefore, most patients with malignant bili...
The aim of this study is to determine whether administration of aspirin can help maintain the patency of metallic stents for distal malignant common bile duct obstruction. Metal stents are...
This is a a prospective study of the WallFlex™ Biliary Partially-covered Stent designed to collect data to support regulatory clearance by the FDA in the United States and to determine t...
ERCP-guided biliary drainage (ERCP-BD is a criterion standard treatment for malignant biliary obstruction when curative surgery is not an option. Alternative methods such as PTBD would significantly l...
The impact of preoperative biliary drainage (PBD) on postoperative morbidity and mortality in patients with malignant biliary obstruction is still unclear. We examined short-term surgical outcomes amo...
To evaluate clinical outcomes of endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) for unresectable malignant biliary obstruction for cases in which endoscopic retrograde cholangiopancreato...
Endoscopic nasobiliary drainage (ENBD) is often recommended in preoperative biliary drainage (PBD) for hilar malignant biliary obstruction (MBO) but endoscopic biliary stent (EBS) is also used in the ...
Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstruction. We aimed to compare stent patency, adverse events rate and overall survival of covered (Niti-S Biliary ComVi) ve...
FIBROSIS of the hepatic parenchyma due to obstruction of BILE flow (CHOLESTASIS) in the intrahepatic or extrahepatic bile ducts (BILE DUCTS, INTRAHEPATIC; BILE DUCTS, EXTRAHEPATIC). Primary biliary cirrhosis involves the destruction of small intra-hepatic bile ducts and bile secretion. Secondary biliary cirrhosis is produced by prolonged obstruction of large intrahepatic or extrahepatic bile ducts from a variety of causes.
Progressive destruction or the absence of all or part of the extrahepatic BILE DUCTS, resulting in the complete obstruction of BILE flow. Usually, biliary atresia is found in infants and accounts for one third of the neonatal cholestatic JAUNDICE.
Abnormal passage in any organ of the biliary tract or between biliary organs and other organs.
Chronic inflammatory disease of the BILIARY TRACT. It is characterized by fibrosis and hardening of the intrahepatic and extrahepatic biliary ductal systems leading to bile duct strictures, CHOLESTASIS, and eventual BILIARY CIRRHOSIS.
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
