BACKGROUND: The aim of the present study was to determine the prevalence of hepatic artery stenosis (HAS) and the prognostic implications of hepatic arterial collaterals in liver transplant (LT) recipients with biliary strictures. METHODS: 105 LT recipients transplanted between 2004 and 2015 at our center had documented biliary strictures. HAS and collaterals were assessed in high quality imaging of the hepatic artery available from 66 recipients. Clinical, demographic and biochemical recipient and donor data were retrospectively analyzed and tested for their association with biliary of arterial complications after LT...

The physiologically-based model with segregated flow to the intestine (SFM-PBPK; partial, lower flow to enterocyte region vs. greater flow to serosal region) was found to describe first-pass glucuronidation of morphine (M) to morphine-3β-glucuronide (MG) in rats after intraduodenal (ID) and intravenous (IV) administration better than the traditional model (TM), for which a single intestinal flow perfused the whole of the intestinal tissue. The SFM described a greater extent of intestinal M glucuronidation for ID vs...

BACKGROUND: Evidence from controlled trials and meta-analyses suggests that laparoendoscopic rendezvous (LERV) is preferable to sequential treatment in the management of common bile duct stones. MATERIALS AND METHODS: With this retrospective analysis of a prospective database that included consecutive patients treated for cholecystocholedocholithiasis at our institution between January 2007 and July 2015, we compared LERV with sequential treatment. The primary endpoint was global cost, defined as the cost/patient/hospital stay, and the secondary end points were efficacy and morbidity...

Recent studies have revealed that deep pancreatic duct wire passage, even in the absence of contrast injection, is a major technique-related culprit in post-ERCP pancreatitis, unless followed by placement of a pancreatic stent. As guidewire cannulation becomes increasingly widespread, precise control of the guidewire is thus critical. The first randomized trial to compare endoscopist-controlled wire guided vs. assistant-controlled bile duct cannulation has shown a significant reduction in post ERCP pancreatitis when the physician manipulates the wire...

Sepsis and septic shock are characterized by life-threatening organ dysfunction caused by a dysregulated host response to infection. The liver has a central role during sepsis, and is essential to the regulation of immune defence during systemic infections by mechanisms such as bacterial clearance, acute-phase protein or cytokine production and metabolic adaptation to inflammation. However, the liver is also a target for sepsis-related injury, including hypoxic hepatitis due to ischaemia and shock, cholestasis due to altered bile metabolism, hepatocellular injury due to drug toxicity or overwhelming inflammation, as well as distinct pathologies such as secondary sclerosing cholangitis in critically ill patients...

Accumulation of hydrophobic bile acids in the liver contributes to cholestatic liver injury. Inflammation induced by excessive bile acids is believed to play a crucial role, however, the mechanisms of bile acids triggered inflammatory response remain unclear. Recent studies have highlighted the effect of NLRP3 inflammasome in mediating liver inflammation and fibrosis. In this study, we for the first time showed that chenodeoxycholic acid (CDCA), the major hydrophobic primary bile acid involved in cholestatic liver injury, could dose-dependently induce NLRP3 inflammasome activation and secretion of pro-inflammatory cytokine-IL-1β in macrophages by promoting ROS production and K+ efflux...

: Hepatitis A virus (HAV) is an unusual picornavirus that is released from cells cloaked in host-derived membranes. These quasi-enveloped virions (eHAV) are the only particle type circulating in blood during infection, whereas only nonenveloped virions are shed in feces. The reason for this is uncertain. Hepatocytes, the only cell type known to support HAV replication in vivo, are highly polarized epithelial cells with basolateral membranes facing onto hepatic (blood) sinusoids and apical membranes abutting biliary canaliculi from which bile is secreted to the gut...

Patients with non-alcoholic fatty liver disease (NAFLD) have an increased risk for progression to hepatocellular carcinoma in addition to comorbidities such as cardiovascular and serious metabolic diseases; however, the current therapeutic options are limited. Based on our previous report that omega-3 polyunsaturated fatty acids (n-3 PUFAs) can significantly ameliorate high fat diet (HFD)-induced NAFLD, we explored the therapeutic efficacy of n-3 PUFAs and N-IgY, which is a chicken egg yolk-derived IgY specific for the Niemann-Pick C1-Like 1 (NPC1L1) cholesterol transporter, on NAFLD in mice...

BACKGROUND: Hyperbaric oxygen (HBO) therapy may improve cholestasis, increase hepatic regeneration, and decrease oxidative stress in liver. In this study, we aimed to investigate the effects of HBO therapy on hepatic oxidative stress parameters, such as total thiol groups (T-SH), protein carbonyl (PCO), and total antioxidant capacity (TAC) as well as the predictive value of the noninvasive biochemical marker, sialic acid (SA), and prolidase activity in bile duct ligation (BDL)-induced oxidative damage and fibrosis in rats...

Wilms tumor 1 (WT1) is considered to be a promising target of cancer treatment because it has been reported to be frequently expressed at high levels in various malignancies. Although WT1-targeted cancer treatment has been initiated, conclusive detection methods for WT1 are not established. The present study aimed to consolidate immunohistochemistry for WT1 with statistical basis. Transfected cells with forced WT1 expression yielded specific western blot bands and nuclear immunostaining; cytoplasmic immunostaining was not specifically recognized...

BACKGROUND: Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease of unknown cause that is characterized pathologically by an inflammatory and fibrotic process centered on the epithelium, leading to diffuse biliary stenosis and increased wall thickness throughout the intra- and extra-hepatic biliary trees. A nationwide survey in Japan revealed several differences in the clinical aspects of PSC between Japan and Western countries. PSC was recently designated an intractable hepatobiliary disease in Japan...

Acute pancreatitis (AP) in the early postlaparoscopic cholecystectomy (LC) period is a rare complication. The cause is often a missed common bile duct stone. Having been reported only once before, we present a second case of AP after LC caused by hemobilia secondary to hepatic artery pseudoaneurysm. The management of this complication is distinctly different from the treatment for AP caused by a stone and must be done on an emergency basis.

BACKGROUND: MRCP is the method of choice in diagnosing pathologies of the biliary system. One of them is bile fistulae. They are uncommon but tend to cause many diagnostic problems. The possible way to improve MRCP is using it with intravenous injection of hepatobiliary-specific contrast agents. As it is eliminated via the hepatobiliary system, it can be visualized in the bile ducts and may help to reveal disorders undetected by a standard MRCP. CASE REPORT: We report a case of a 36-year-old woman with leakage in the biliary system which led to creation of a subcutaneous bile reservoir...
