REVIEW
Amardeep Khanna, David E Jones
Primary biliary cholangitis (PBC) is a chronic autoimmune liver disease. It has a varied course of progression ranging from being completely asymptomatic to aggressive disease leading to cirrhosis and resulting in liver transplantation. In addition, symptoms can be debilitating and can have a major impact on quality of life. For decades, there was only one anti-cholestatic agent available to target this disease and that was only effective in around half of patients, with little or no effect on symptoms. With increasing understanding of the pathogenic mechanisms of PBC and potential targets for drug treatment, pharmaceutical companies have shown a greater interest in this rare disease...

Biliary atresia leads to cirrhosis in the vast majority of patients and constitutes the first cause of paediatric liver transplantation. Animal models allow us to understand the molecular basis and natural history of diseases. The aim of this study is to describe a surgically created animal model of biliary atresia with emphasis in long-term liver function. Forty-two 3-week-old Sprague-Dawley rats were randomly divided into two groups: bile duct ligature (BDL) and control. The animals were sacrificed on the 2nd, 4th, and 6th postoperative weeks...

BACKGROUND: The current (seventh edition) American Joint Commission on Cancer (AJCC) Staging System for pancreatic ductal adenocarcinoma (PDAC) dichotomizes pathologic lymph node (LN) involvement into absence (pN0) or presence (pN1) of disease. The recently announced eighth edition also includes stratification on the number of positive nodes. Furthermore, LNs detected on preoperative imaging (CT, MRI, or endoscopic ultrasound-EUS) are considered to be pathologically involved in other gastrointestinal cancers...

PURPOSE: Pediatric patients with intestinal failure need long-term parenteral nutrition (PN), but this nutritional support causes liver dysfunction, such as intestinal failure-associated liver disease (IFALD). Several studies have shown that the lipid emulsion produced by soybean oil (SO) is associated with the occurrence of IFALD. In this study, we evaluated the effect of SO and fish oil (FO) lipid emulsion on hepatic steatosis. METHODS: Sprague-Dawley rats underwent jugular vein catheterization and were divided into three groups: sham operation with normal chow (Sham group), 80% small bowel resection (80% SBR) + TPN with SO lipid emulsion (SO group), and 80% SBR + TPN with FO lipid emulsion (FO group)...

Liver abscess is the most common type of visceral abscess reported in the United States. Biliary tract disease is the most common cause of the development of liver abscess. In the last decade, many cases of liver abscesses silently manifesting as colon cancer have been reported in East Asian countries. We herein describe a case of an immunocompetent man who immigrated from East Africa to Unites States and presented with a suspicion of colon mass with metastasis to the liver, and who was later diagnosed to have a colonic malignancy with a concomitant liver abscess...

Although researchers have identified genetic alterations that contribute to development of esophageal adenocarcinoma, we know little about features of patients or environmental factors that mediate progression of chronic acid biliary reflux to Barrett's esophagus and cancer. Increasing our understanding of the mechanisms by which normal squamous epithelium progresses to early-stage invasive cancer will help formulate rational surveillance guidelines and allow us to divest resources away from patients at low risk of malignancy...

BACKGROUND: Biliary dyskinesia is a controversial clinical entity. Standardized diagnostic test and management guidelines are lacking in children. Published data suggest that long-term outcomes of surgical and medical management are similar. We sought to determine national population-based trends of cholecystectomies performed in children for biliary dyskinesia and associated healthcare expenditure in the US over a 10-year period. METHODS: Using Nationwide Inpatient Sample and the International Classification of Diseases, the 9th revision clinical modification codes, we identified children who had a cholecystectomy for biliary dyskinesia from 2002-2011 in the United States...

Cystic echinococcosis is an infectious disease that is potentially associated with the biliary tract. Of thousand cases of hydatid cysts that were successfully treated by the Örmeci method, only two presented with cholangitis subsequent to the percutaneous treatment. These cases were treated with endoscopic retrograde cholangiopancreatography, and this study provides details regarding the clear fistulization of hydatid cysts into the biliary tract.

Biliary atresia (BA) is a common cause of pediatric end-stage liver disease. While its etiology is not yet clear, evidence has suggested that BA results from interactions between genetic susceptibility and environmental factors. Disease relevant human cellular models of BA will facilitate identification of both genetic and environmental factors that are important for disease prevention and treatment. Here we report the generation of a human induced pluripotent stem cell line from a BA patient using episomal vectors...

Gallbladder carcinoma is the most common and aggressive malignancy of the biliary tree and highly expresses CD147, which is closely related to disease prognosis in a variety of human cancers. Doxycycline exhibited anti-tumor properties in many cancer cells. CD147 antagonist peptide-9 is a polypeptide and can specifically bind to CD147. The effect of these two drugs on gallbladder cancer cells has not been studied. The aim of this study is to investigate the effect of doxycycline and antagonist peptide-9 on gallbladder carcinoma cells and the possible mechanism of inhibition on cancer cell of doxycycline...

Bronchobiliary fistula (BBF), a rare complication of liver disease, is an abnormal communication between the biliary tract and bronchial tree. BBF may occur as a consequence of local liver infections such as hydatid or amebic disease, pyogenic liver abscess or trauma to the liver, obstruction of biliary tract, and tumor. As such management of liver disease with BBF is very difficult and often associated with a high rate of morbidity and mortality. Therefore, timely diagnosis of BBF is imperative. Hepatobiliary scintigraphy along with hybrid single photon emission computed tomography/computed tomography using Tc99m-mebrofenin is a very useful noninvasive imaging modality, in the diagnosis of BBF...

A Thébaut, D Debray, E Gonzales
Pruritus is a disabling symptom accompanying chronic cholestasis. In extreme cases, the refractory nature of pruritus can result in a need for invasive therapies including liver transplantation. The pathogenesis of pruritus in cholestatic disease is poorly understood. It may involve a specific neural pathway (similar to that associated with pain) regulated by several pruritogenic substances such as bile acids, opioids, serotonin, and the more recently identified lysophosphatidic acid. While the therapeutic management of cholestatic pruritus is well established in adults, there is no consensus in children, in light of the difficulty of conducting controlled clinical studies...

BACKGROUND This is the largest UK-based study on the effect of recipient body mass index (BMI) and its extremes (BMI <18.5 and BMI ≥35 kg/m²) on liver transplant (LT) outcomes. Its purpose was to analyze the BMI effect on post-LT mortality, graft loss, primary non-function (PNF), and graft vascular and biliary complications. MATERIAL AND METHODS Data were retrieved from a single-center LT database of 2,115 consecutive patients receiving first LT during period February 2004 to September 2015. Survivals were compared across the BMI groups; the effects of recipient BMI on survival, PNF, and graft vascular and biliary complications were analyzed via regression...

Biliary atresia (BA) is a unique cholestatic disease of newborns with a background of exaggerated immune response in the liver of unknown mechanism. Three hypotheses have been proposed; autoimmune type of cholangiopathy triggered by virus infection, graft-versus-host disease type of immune-mediated disease associated with maternal microchimerism and ductal plate malformation theory. Researchers on virus infection theory have experimentally explored immune process causing cholangiopathy on murine models of this disease, while in maternal microchimerism hypothesis were detected maternal cells in the BA patients' liver, of which roles are yet to be determined...

Liver transplant is considered to be the last-resort treatment approach for pediatric patients with end-stage liver disease. Despite the remarkable advance in survival rates, liver transplant remains an intricate surgery with significant morbidity and mortality. Early diagnosis of complications is crucial for patient survival but is challenging given the lack of specificity in clinical presentation. Knowledge of the liver and vascular anatomy of the donor and the recipient or recipients before surgery is also important to avoid complications...
