The prognosis of patients with unresectable and recurrent biliary tract cancer (BTC) is very poor. Although gemcitabine (GEM) plus cisplatin therapy is useful for unresectable cases, the median overall survival (OS) of the patients is <1 year, and third-line chemotherapy following failure of 5-fluorouracil (5-FU) and GEM plus cisplatin is currently unavailable. The clinical efficacy and basic effects of low-dose paclitaxel (PTX) therapy for patients with BTC was previously reported. We herein present the results of a phase I clinical trial of weekly low-dose PTX as third-line palliative chemotherapy...

Gallbladder carcinoma (GBC) is the most common biliary tract cancer and exhibits poor patient prognosis. Previous studies have identified that long non-coding RNAs (lncRNAs) serve important regulatory roles in cancer biology. Alterations in lncRNAs are associated with several types of cancer. However, the contribution of lncRNAs to GBC remains unclear. To investigate the lncRNAs that are potentially involved in GBC, lncRNA profiles were identified in three pairs of human GBC and corresponding peri-carcinomatous tissue samples using microarray analysis...

INTRODUCTION: Biliary complications occur in 10-30% of liver transplants. The aim of this study was to compare the incidence of these complications in liver transplants when the T-tube was or was not used during the biliary anastomosis. MATERIAL AND METHODS: Analysis of 2 groups of patients undergoing liver transplantation between 2008 and 2012. Patients were divided considering if the T-tube was used (G1) or if it was not (G2). We sought explanatory models of the occurrence of biliary complications by logistic regression, including the variables identified in the univariate analysis...

A double common bile duct is extremely rare among the anatomical variations in the biliary tract system. We report an incidentally encountered case of the double common bile duct and discuss the novel anatomical findings of the accessory common bile duct from the viewpoint of embryology. A unique point of our case is that the accessory common bile duct bifurcated at the level of the intrapancreatic bile duct. There is no similar case in the previous literature among type II double common bile duct in the viewpoint of anatomical findings of the accessory common bile duct...

AIM: To investigate the association between a recent gastrointestinal (GI) endoscopy and the subsequent risk of pyogenic liver abscess (PLA). METHODS: We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were selected as reference controls. We identified and compared the possible risk factors for PLA and GI endoscopies performed before the index date (when PLA was diagnosed) between the two cohorts...

Autoantibody detection for autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and autoimmune gastritis (AIG) is traditionally performed by IIF on a combination of tissues. Multiplex line/dot blots (LIA/DIA) offer multiple advantages, i.e. automation, objective reading, no interfering reactivities, no coincidental findings. In the current study we evaluated automated DIA (D-Tek) for detecting autoantibodies related to autoimmune diseases of the gastrointestinal tract. We tested samples of the Dutch EQC program and compared the results with the consensus of the participating labs...

This article aims to describe step-by-step technique performed with the aid of a video. We report the performance of an endoscopic approach to the biliary tract on 2 patients who had previously undergone duodenal switch (DS). It was successfully performed a laparoscopic-assisted transenteric endoscopic retrograde cholangiopancreatography (ERCP) in both the patients. Although successful experiences with ERCP after Roux-en-Y gastric bypass have been found, few cases of ERCP after DS have been reported. Nevertheless, this is the first study to include a multimedia video with description of details and all technical steps of the transenteric ERCP performed on 2 patients who had previously undergone DS...

Rotavirus infection is one of the most common causes of diarrheal illness in humans. In neonatal mice, rhesus rotavirus (RRV) can induce biliary atresia (BA), a disease resulting in inflammatory obstruction of the extra-hepatic biliary tract and intrahepatic bile ducts. We have previously shown that the amino acid, arginine (R) within the sequence "SRL" (amino acids 445-447) on the RRV VP4 protein is required for viral binding and entry into biliary epithelial cells. To determine if the single amino acid (R) influences the pathogenicity of the virus, we generated a recombinant virus with a single amino acid mutation at this site through a reverse genetics system...

PURPOSE OF REVIEW: IgG4-related disease (IgG4-RD) is an immune-mediated disease of unknown cause. It predominantly affects the biliary tract [IgG4-associated cholangitis (IAC)] and pancreas [autoimmune pancreatitis (AIP)] of mostly elderly men. Accurate diagnostic tests are lacking. Patients benefit from predniso(lo)ne treatment. However, disease relapse is often seen. This review will address pathophysiological aspects and advances in diagnostic and therapeutic strategies. RECENT FINDINGS: The role of IgG1 and IgG4 in the pathophysiology of IgG4-RD was studied in mice which showed more intense organ damage of pancreas and salivary glands when IgG1 rather than IgG4 of patients with IgG4-RD was injected...

This case describes a technique used to close a long-term 14F transpleural biliary drainage catheter tract to prevent biliopleural fistula and further complications. We deployed a compressed gelatin foam pledget provided in a pre-loaded delivery device (Hep-Plug™) along the intrahepatic tissue tract for sealing it against the pleural cavity. The device used is easy to handle and gives the Interventional Radiologist the possibility to safely manage and prevent complications after percutaneous transhepatic interventions...

INTRODUCTION: Bacterial infection and bile flow retardation form a vicious cycle which promotes stone formation and recurrence, and it seems that mucin overexpression plays an important role in this process. However, the mechanism of increased mucus secretion in the biliary tract by bacterial infection and its treatment remain unclear. MATERIAL AND METHODS: Human biliary epithelial cells were induced by neutrophil elastase (NE), and H2O2 production in the cell supernatants was detected by a specific kit, and then cells were pretreated with a H2O2 inhibitor, and expression of MUC5AC was detected by real-time polymerase chain reaction (PCR), Western blot, and immunohistochemistry...

Intrahepatic cholangiocarcinoma (ICC) is a rare entity with a distinct clinical course and epidemiology from hilar and extrahepatic cholangiocarcinoma. ICC makes up 8-10% of cholangiocarcinomas and 10-20% of all primary liver tumors. There remains a considerable amount of geographic variation in the incidence of ICC worldwide; however, the overall incidence of this malignancy appears to be rising. Several risk factors have been identified, such as infectious causes (liver flukes, viral hepatitis), biliary tract disease [primary sclerosing cholangitis (PSC), hepaticolithiasis, biliary cystic diseases], metabolic syndrome, lifestyle choices (alcohol abuse, tobacco use), and cirrhosis...

Biliary tract cancer (BTC) is a heterogeneous group of cancers, which is composed of intrahepatic cholangiocarcinoma (ICCA), extrahepatic cholangiocarcinoma (ECCA), gallbladder cancers and ampullary carcinomas. While all anatomic subgroups are treated uniformly, our understanding about the pathogenesis has allowed us to reason that each group represents a clinically and genetically diverse disease. The majority of patients present with locally advanced or metastatic disease, where the standard treatment is combination systemic cytotoxic chemotherapy with gemcitabine and cisplatin...

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer, accounting for 10-15% of primary hepatic malignancy. The incidence and cancer-related mortality of ICC continue to increase worldwide. At present, hepatectomy is still the most effective treatment for ICC patients to achieve long-term survival, although its overall efficacy may not be as good as that for patients with hepatocellular carcinoma (HCC) due to the unique pathogenesis and clinical-pathological profiles of ICC. Viral infection, lithiasis and metabolic factors may all be associated with the pathogenesis of ICC...

The treatment of biliary stenosis after pediatric LDLT is challenging. We describe an innovative technique of peripheral IHCJ for the treatment of patients with complex biliary stenosis after pediatric LDLT in whom percutaneous treatment failed. During surgery, the percutaneous biliary drainage is removed and a flexible metal stylet is introduced trough the tract. Subsequently, the most superficial aspect of the biliary tree is recognized by palpation of the stylet's round tip in the liver surface. The liver parenchyma is then transected until the bile duct is reached...

Gallbladder cancer (GBC) is one of the most common malignancy of the biliary tract characterized by its high chemoresistant tendency. Although great progresses have been made in recent decades for treating many cancers with anticancer drugs, effective therapeutics methods for anti-GBC are still lacking. Therefore, investigations into identifying the mechanisms underlying the drug resistance of GBC are greatly needed. In this study, we show that miR-218-5p plays a critical role in gemcitabine resistance of GBC...

Stereotactic body radiation therapy (SBRT) is delivered in a curative intent to many primary and secondary tumors. Concerning liver metastasis, SBRT can be safely delivered using one to five fractions. An excellent local control is obtained with doses from 20 to 60 Gy. For primary hepatic tumors, results are also good, but the risk of hepatic toxicity related to liver pre-existent pathology must be taken into account. Radiation induced liver disease (RILD) is not frequent in its classical presentation, but modifications of liver enzymes are often observed...

BACKGROUND: Biliary tract malignancies, in particular cholangiocarcinomas (CCA), are rare tumors that carry a poor prognosis. BRCA2 mutation carriers have an increased risk of developing CCA with a reported relative risk of ∼5 according to the Breast Cancer Linkage Consortium. In addition to this risk, there are potential therapeutic implications in those harboring somatic and/or germline (GL) BRCA mutations. Therefore, it is important to define the clinical characteristics of GL/somatic BRCA1/2 variants in CCA patients...
