Surgical Strategy of Hepatocellular Carcinoma with Bile Duct Tumor Thrombus
… for hepatocellular carcinoma (HCC) with bile duct tumor thrombus (BDTT) have not been well assessed. This study intended to research the surgical strategy of HCC patients with BDTT. Methods: From February 1994 to December 2012, 877 HCC patients underwent hepatic resection in Ajou …

A cost analysis of operative repair of major laparoscopic bile duct injuries
Major bile duct injuries occur infrequently after laparoscopic cholecystectomy but may result in life-threatening complications. Few data exist about the financial implications of bile duct repair. This study calculated the total inhospital costs of operative repair in a cohort of patients who …

The surgical management and prevention of laparoscopic cholecystectomy associated bile duct injuries
… performed general surgery operations worldwide. Bile duct injury (BDI) in LC remains a feared complication as it is associated with significant morbidity, prolonged hospital stay, increased costs, and reduced quality of life for patients, as well as the risk of litigation for the injuring …

Endoscopic large-balloon dilation alone versus endoscopic sphincterotomy plus large-balloon dilation for the treatment of large bile duct stones
… been proposed as an alternative to manage large bile duct stones. However, recent reports indicate that LBD without EST may be safe and effective in this setting. One hundred thirty-one patients with large common bile duct (CBD) stones 12 mm in size or larger underwent LBD alone (n = 62) or EST …

Chirurgie der extrahepatischen Gallenwegskarzinome
The carcinoma of the extrahepatic bile duct and gallbladder has with the exception of the carcinoma of the papilla of Vater a very bad prognosis. Even though resection rates and perioperative mortality were improved, the survival rates remain unfavourably. This study investigated retrospectively …

Therapeutic Gene Delivery to Human Pancreatic Islets for Treatment of Diabetes and the Effect of TFO on Liver Fibrosis Induced by Bile Duct Ligation
… of plasmid DNA and the better known islet transduction efficiency of adenoviral (Adv) vectors, in this study, we constructed Adv‑hVEGF‑hIL‑1Ra by cloning hVEGF and hIL‑1Ra coding sequences and polyA signal under separate cytomegalovirus (CMV) promoters in Adenoquick plasmid (Ad 13.1). There was …

Physical and chemical changes in porcine gastric mucus in the normal and ulcerated status
… pars oesophagea of the pig's stomach following bile duct ligation. The reproducibility of this model has made possible its use in the investigation of the biochemical aspects of mucus secretion in both the normal state and at various states of ulceration. The main findings are summarised below: …

Taurocholat-Transport in isolierten proximalen Tubuluszellen der Ratte : Einfluss einer extrahepatischen Cholestase
… the non-protein bound fractions of plasma bile acids are filtered in the glomeruli. The bile acids reaching the tubular fluid are nearly completely reabsorbed by the apical sodium-dependent bile salt transporter (asbt). Hence, with normal conditions, urinary excretion of bile acids is …

Do balloons larger than 15 mm in size increase the risk of adverse events in endoscopic large balloon dilation?
… introduced to facilitate the removal of large bile duct stones and minimize the need for endoscopic mechanical lithotripsy (EML). Much recent literature has suggested EPLBD is safe and effective for extraction of large or difficult stones without any additional risk of lifethreatening …

A study of the effects of sucralfate in the bile duct litigated pig peptic ulcer model with particular reference to the effects on the physico-chemical properties of gastric mucus and including comparisons with famotidine and misoprostol
… porcine model of peptic ulceration, the bile duct ligated pig. In addition, the effects of Sucralfate were compared with those of Famotidine and Misoprostol, and changes in mucous prostaglandins, gastric juice pepsin and gastric flora were sought. By way of introduction, the known and …

Understanding regional diversity in the human biliary tree through transcriptomic profiling of primary tissues and in vitro derived organoids
The biliary tree is a series of ductular tissues responsible for the drainage of bile produced by the liver and pancreatic secretions from the pancreas. The biliary tree is affected by a diversity of life- threatening diseases collectively called cholangiopathies. Cholangiopathies show …

Auswirkungen der obstruktiven Cholestase auf die intestinale Expression von MRP2 bei Ratten und Menschen
… of MRP2 in male Sprague-Dawley rats with bile duct ligation (BDL) or biliary diversion as well as in 20 cholestatic patients with biliary obstruction. In biliary obstruction, but not biliary depletion, intestinal Mrp2 protein mass was reduced to 9.3% ± 5.5% of controls and mRNA to 40.5% ± …

Which pre-operative findings translate to a positive intra-operative cholangiogram?
… have a low sensitivity for detecting common bile duct stones amongst the intermediate-risk groups. Aim: Identify pre-operative findings which predict choledocholithiasis in intermediate-risk groups. Describe the implications of a positive intra-operative cholangiogram (IOC). Method: A …

Finite Element Analysis of a Novel Design for a Non-Migrating Biliary Stent
… by an interruption in the ability to drain bile into the duodenum. This obstructive jaundice is commonly a result of a stricture from a tumor located at the pancreas’s head, peri-ampulary area, bile duct, or gall bladder. Jaundice can also occur from anastomotic strictures which result from …

The role of the mechanical microenvironment in regulation of cholangiocyte specification and tubulogenesis
… I then employed this system to study bile duct specification and morphogenesis in vitro using well-established differentiation protocols (Hannan et al. 2013b; Sampaziotis et al. 2017). Through carefully controlling the ECM, I observed that high densities of collagen type I serve as an …

TGF-β Signaltransduktion in der experimentell induzierten Leberfibrose durch die Gallengangsligatur bei der Ratte
… Here, liver fibrosis was assessed subsequent to bile duct ligation by determining liver enzymes in serum and collagen deposition in liver tissue. Activated hepatic stellate cells were identified by immunohistochemistry and immunoblots for alpha smooth muscle actin. Cellular localization of Smad3 …

Leber-Fibrose: Erstellung eines Modells zur Analyse lebertoxischer Substanzen und Analyse der ltbp1-abhängigen Aktivierung hepatischer Sternzellen
… in vivo using an experimental model for the induction of liver fibrosis (ligation of the common bile duct). After 4 weeks of bile duct obstruction, ltbp1-/- mice showed markedly reduced signs of liver fibrosis, i.e. less Collagen I deposition by HSC in the affected liver parenchyma. The study …
