Conclusions:  Wire

assisted transpancreatic septotomy is a safe and effective alternative technique to traditional NK in patients who have failed standard BC techniques. It also allows other pre-cut techniques such as NK to be used should initial WTS be unsuccessful. “

“Damage to the hepatic vessels can be caused by iatrogenic factors, systemic diseases, prothrombotic disorders or hereditary hemorrhagic telangiectasia. Several uncommon clinical entities are related to these vascular disorders. (a) ischemic cholangiopathy, due to impaired hepatic arterial inflow, consists of necroses and/or stenoses of the bile ducts, or ductopenia; (b) Budd–Chiari syndrome (mostly due to thrombosis of the hepatic Vemurafenib order veins or terminal portion of inferior vena cava); and (c) sinusoidal obstruction syndrome – venoocclusive disease (mostly due to toxic injury), both cause ascites, portal hypertension and marked hepatic dysfunction. (d) Acute portal vein thrombosis causes acute abdominal pain and may be complicated by intestinal infarction. (e) Noncirrhotic portal hypertension can be caused by chronic extrahepatic portal vein obstruction (generally due

to thrombosis), obstruction of hepatic microcirculation (including schistosomiasis), or arterioportal fistula. “
“Aim:  Mast cells may be involved in the pathogenesis of nonalcoholic selleck chemical steatohepatitis (NASH). The mast cell protease click here chymase contributes to the formation of angiotensin II and matrix metalloproteinase (MMP)-9, both of which are intimately involved in liver fibrosis. Therefore, we hypothesized that chymase plays an important role in the development

of NASH. Methods:  Hamsters were fed a methionine- and choline-deficient (MCD) diet for 8 weeks. These animals were divided into two groups and received either TY-51469 (1 mg/kg per day) or placebo. A third group was fed a normal diet as a control. Results:  Total plasma bilirubin, triglycerides, and hyaluronic acid levels were significantly higher in the MCD diet-fed hamsters than in the normal diet-fed hamsters, but the levels were significantly lower in chymase inhibitor-treated MCD diet-fed hamsters than in placebo-treated MCD diet-fed hamsters. Using histological analysis, marked steatosis and fibrosis were observed in MCD diet-fed hamsters, but these changes were significantly attenuated by treatment with the chymase inhibitor. Increases in mast cells and chymase-positive cells were observed in the liver after the MCD diet, but the increases disappeared in the chymase inhibitor-treated group. The significant increase observed in chymase activity in liver tissue extract from the MCD diet-fed group was also reduced by treatment with the chymase inhibitor. Chymase inhibition significantly reduced not only angiotensin II expression but also matrix metallopeptidase 9 activity in MCD diet-fed hamsters.
