We read the article entitled 'Endoscopic biodegradable biliary stents in the treatment of benign biliary strictures: First report on clinical use in patients' by Siiki et al with great interest (1). The authors successfully treated two patients with benign biliary strictures, possibly due to choledocholithiasis, with endoscopic insertion of polydioxanone biodegradable biliary stents. They reported that the treatment was uneventful and the stents were completely dissolved between 3 and 6 months without leaving a sequela in the bile ducts...

Hepatic innervation represents a potentially underestimated regulator of liver function and regeneration. The muscarinic 3 receptor (M3 -R) is the primary cholangiocyte receptor for the afferent parasympathetic innervation of bile ducts. We aimed to determine the specific role of the M3 -R in bile formation and models for cholestatic liver disease in mice. We compared bile flow and composition in M3 -R knock-out mice (M3 -R(-/-) ) and wild type littermates (WT). M3 -R(-/-) mice showed significantly reduced bile flow compared to WT mice, most likely due to decreased biliary HCO3(-) secretion...

BACKGROUND: Hepatic artery aneurysms (HAAs) constitute 14% to 20% of visceral artery aneurysms. Most HAAs are asymptomatic. Although rare, obstructive jaundice due to external bile duct compression or rupture of the HAA into the biliary tree with occlusion of the lumen from blood clots has been reported. CASE PRESENTATION: A 56-year-old white man presented to an outside hospital with symptoms of obstructive jaundice, including abdominal pain and yellowing of the skin...

Pathogen-associated biliary fibrosis (PABF) is a type of liver fibrosis characterized by injuries of cholangiocytes and extra cellular matrix (ECM) deposition around bile ducts caused by various bacteria, fungi, virus and parasites. Recent studies show that TLR4 plays an important role in several other types of liver fibrosis, but the mechanism of TLR4 in PABF is yet really unclear. In the present study, a PABF mouse model was established by a trematode infection-Clonorchis sinensis which dwells in the bile ducts and causes severe biliary fibrosis of mice...

Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

Melatonin therapy or prolonged exposure to complete darkness reduces biliary hyperplasia and liver fibrosis in bile-duct-ligated (BDL) rats; however, no information exists in primary sclerosing cholangitis (PSC). Thus, we aimed to determine the therapeutic effects of prolonged dark therapy or melatonin administration on hepatic fibrosis in the Mdr2(-/-) mouse model of PSC. Melatonin levels, biliary mass, liver fibrosis, angiogenesis and miR-200b expression were evaluated in wild-type and Mdr2(-/-) mice exposed to darkness or melatonin treatment or in male PSC patient samples and healthy controls...

BACKGROUND: Rupture of the common bile duct is a life-threatening condition, usually observed after a trauma or in association with choledocholithiasis or an obstructive tumor of the bile duct. However, a spontaneous rupture of the common bile duct is a rare entity. CASE PRESENTATION: We report a new observation of a spontaneous rupture of the common bile duct, associated with biliary peritonitis and pancreatitis, in a 15-year-old North African girl. Etiological aspects, specificities of clinical presentation, means of diagnosis, as well as surgical and perioperative management are discussed...

Moon Joo Hwang, Tae Nyeun Kim
Caroli disease (CD) is a rare congenital malformation of the liver characterized by non-obstructive, segmental, cystic dilatation of the intrahepatic bile ducts (IHDs). The clinical course is usually asymptomatic for the first 5-20 years, and symptoms may seldom occur throughout the patient's life. Bile stagnation leads to recurrent episodes of cholangitis, stone formation, or liver abscesses, and biliary cirrhosis usually occurs years later. Here we report on a 42-year-old man diagnosed with diffuse-type CD with a characteristic central dot sign, who had multiple intrahepatic and common bile duct (CBD) stones...

PURPOSE: We compared diagnostic performance of Magnetic Resonance (MR), Computed Tomography (CT) and Ultrasound (US) with (CEUS) and without contrast medium to identify peribiliary metastasis. METHODS: We identified 35 subjects with histological proven peribiliary metastases who underwent CEUS, CT and MR study. Four radiologists evaluated the presence of peribiliary lesions, using a 4-point confidence scale. Echogenicity, density and T1-Weigthed (T1-W), T2-W and Diffusion Weighted Imaging (DWI) signal intensity as well as the enhancement pattern during contrast studies on CEUS, CT and MR so as hepatobiliary-phase on MRI was assessed...

OBJECTIVE: Hepatopulmonary syndrome (HPS) is characterized by hypoxia in patients with chronic liver disease. The mechanism of HPS includes pulmonary vasodilatation, inflammation, and angiogenesis. Prostaglandins synthesized by cyclooxygenases (COX) participate in vascular responsiveness, inflammation and angiogenesis, which can be modulated by COX inhibitors. We therefore evaluated the impact of COX inhibition in rats with common bile duct ligation (CBDL)-induced liver cirrhosis and HPS...

To describe cell-specific acetylation of histones and their zonal localization in normal mouse liver and characterize their changes in acetaminophen (APAP)-damaged mouse liver 24 hr after APAP exposure, we performed an immunohistochemical study using normal and APAP-injured mouse livers. Cell-specific expression of acetylated H4 was observed in normal mouse liver. The highest acetylated H4 expression levels were found in bile duct epithelial cells, followed by sinusoidal non-parenchymal cells, venous endothelial cells, and hepatocytes...

BACKGROUND: There is still a debate regarding the optimal management of bile duct injury following cholecystectomy. Our aim was to ascertain if delayed referral influenced clinical outcomes for patients with BDI treated in our institution. MATERIALS AND METHODS: We interrogated a prospectively maintained database, including all patients with BDI (Bismuth and Strasberg classifications) post LC managed in our unit from 2000-2014. Referrals were arbitrarily defined as early (<96 hours from the injury) and delayed (>96 hours)...

The article gives our own experience in the determination and study of additional laboratory criteria (total lipids, cholesterol, maximum and area chemiluminescence, antioxidant activity) at the local level (in bile) in patients with bile duct obstruction of malignant etiology. Constellation of metabolic disorders allowed to propose an original method for determining the lithogenicity of bile (integral indicator of lithogenicity). The obtained data made it possible to justify the need to assess the degree of metabolic disturbances in bile, on the basis of which it is possible to predict the risk of lithogenesis and the duration of stent operation, which in turn helped optimize the algorithm for choosing the method of bile ducts decompression aimed at preventing early obturation of endoprostheses...

Pancreaticobiliary maljunction (PBM) is a congenital malformation that is associated with biliary cancer development. When patients are diagnosed with PBM, a diversion operation is recommended. Although a risk remains for developing residual bile duct carcinoma following diversion, the development of a carcinoma of the ampulla of Vater after a diversion operation for PBM is rare. We present a treated case of carcinoma of the ampulla of Vater after a diversion operation for PBM. A 65-year-old woman presented with abdominal pain...

BACKGROUND: Anastomotic bile duct stricture (ABS) remains as one of the most common complications in liver transplant patients. Current practice of endoscopic retrograde cholangiopancreatography (ERCP) with insertion of plastic stent (PS) often requires multiple procedures before achieving stricture resolution. To date, studies utilizing covered self-expandable metallic stent (cSEMS) in ABS management reported varying degree of efficacy. The aim of this study was to analyze long term efficacy of cSEMS in patients with ABS, and identifying factor(s) influencing the probability of stricture resolution...

Our recent work revealed that elevated expression of claudin-18 is involved in bile duct neoplasia. In the present study, we found that wound generation of a cell sheet de novo induced claudin-18 expression in its leading edge, coincident with high mitotic activity. We also found that the suppression of claudin-18 expression significantly reduced cell growth and invasiveness of bile duct cancer cell lines and tumorigenicity in vivo. In addition, an antibody specific to an extracellular loop of claudin-18 showed similar effects on the cells such as cell proliferation...

BACKGROUND: Although laparoscopic transcystic common bile duct exploration (LTCBDE) is the preferred approach for CBD stone clearance, the success rate can vary between 55% and 85%. This study evaluated if ultrathin choledochoscope and holmium laser lithotripsy could improve the success rate of LTCBDE. METHODS: Records of 126 patients (average age, 46.1 ± 13.8 years) with cholecystocholedocholithiasis treated with laparoscopic cholecystectomy (LC) and LTCBDE were retrospectively reviewed...
