| 1 | Probiotics in hepatology显示文摘The paper provides a basic review of intestinal micro- flora and its importance in liver diseases. The intestinal microflora has many important functions, above all to maintain the microbial barrier against established as well as potential pathogens. Furthermore, it influences the motility and perfusion of the intestinal wall, stimu- lates the intestinal immune system and therefore also the so-called common mucosal immune system, re- ducing bacterial translocation and producing vitamins. Immune homeostasis at mucosal level results from a controlled response to intestinal luminal antigens. In liver cirrhosis, there are many changes in its function, mostly an increase in bacterial overgrowth and trans- location. In this review, probiotics and their indications in hepatology are generally discussed. According to recent knowledge, these preparations are indicated in clinical practice only for cases of hepatic encephalopa- thy. Probiotics are able to decrease the permeability ofthe intestinal wall, and decrease bacterial translocation and endotoxemia in animal models as well as in clinical studies, which is extremely important in the prevention of complications of liver cirrhosis and infection after liv- er transplantation. Probiotics could limit oxidative and inflammatory liver damage and, in some situations, improve the histological state, and thus non-alcoholic steatohepatitis could be considered as another possible indication. ? 2011 Baishideng.

| 2 | Spontaneous bacterial peritonitis:A severe complication of liver cirrhosis显示文摘This report presents a survey of current knowledge concerning one of the relatively frequent and severe complications of liver cirrhosis and associated ascites-spontaneous bacterial peritonitis. Epidemiology,aetiology,pathogenesis,clinical manifestation,diagnosis and present possibilities of treatment are discussed. | Jan Lata Oldich Stiburek Marcela Kopacova | 2009 | World Journal of Gastroenterology2009，15，44： | 12 |
| 3 | Hepatorenal syndrome显示文摘Hepatorenal syndrome(HRS) is defined as a functional renal failure in patients with liver disease with portal hypertension and it constitutes the climax of systemic circulatory changes associated with portal hypertension.This term refers to a precisely specified syndrome featuring in particular morphologically intact kidneys,where regulatory mechanisms have minimised glomerular filtration and maximised tubular resorption and urine concentration,which ultimately results in uraemia.The syndrome occurs almost exclusively in patients with ascites.Type 1 HRS develops as a consequence of a severe reduction of effective circulating volume due to both an extreme splanchnic arterial vasodilatation and a reduction of cardiac output.Type 2 HRS is characterised by a stable or slowly progressive renal failure so that its main clinical consequence is not acute renal failure,but refractory ascites,and its impact on prognosis is less negative.Liver transplantation is the most appropriate therapeutic method,nevertheless,only a few patients can receive it.The most suitable 'bridge treatments' or treatment for patients ineligible for a liver transplant include terlipressin plus albumin.Terlipressin is at an initial dose of 0.5-1 mg every 4 h by intravenous bolus to 3 mg every 4 h in cases when there is no response.Renal function recovery can be achieved in less than 50% of patients and a considerable decrease in renal function may reoccur even in patients who have been responding to therapy over the short term.Transjugular intrahepatic portosystemic shunt plays only a marginal role in the treatment of HRS. | Jan Lata | 2012 | World Journal of Gastroenterology2012，18，36： | 4 |
| 4 | Single balloon enteroscopy for endoscopic retrograde cholangiography in patients with Roux-en-Y hepaticojejuno anastomosis显示文摘AIM:To evaluate single balloon enteroscopy in diagnostic and therapeutic endoscopic retrograde cholangiography(ERC)in patients with Roux-en-Y hepaticojejunoanastomosis(HJA).METHODS:The study took place from January 2009to December 2011 and we retrospectively assessed 15patients with Roux-en-Y HJA who had signs of biliary obstruction.In total,23 ERC procedures were performed in these patients and a single balloon videoen-teroscope(Olympus SIF Q 180)was used in all of the cases.A transparent overtube was drawn over the videoenteroscope and it freely moved on the working part of the enteroscope.Its distal end was equipped with a silicone balloon that was inflated by air from an external pump at a pressure of≤5.4 kPa.The technical limitations or rather the parameters of the single balloon enteroscope(working length-200 cm,diameter of the working channel-2.8 mm,absence of Albarran bridge)showed the need for special endoscopic instrumentation.RESULTS:Cannulation success was reached in diagnostic ERC in 12 of 15 patients.ERC findings were normal in 1 of 12 patients.ERC in the remaining 11 patients showed some pathological changes.One of these(cystic bile duct dilation)was subsequently resolved surgically.Endoscopic treatment was initialized in the remaining 10 patients(5 with HJA stenosis,2 with choledocholithiasis,and 3 with both).This treatment was successful in 9 of 10 patients.The endoscopic therapeutic procedures included:balloon dilatation of HJA stenosis-11 times(7 patients);choledocholitiasis extraction-five times(5 patients);biliary plastic stent placement-six times(4 patients);and removal of biliary stents placed by us-six times(4 patients).The mean time of performing a single ERC was 72 min.The longest procedure took 110 min and the shortest took34 min.This shows that it is necessary to allow for more time in individual procedures.Furthermore,these procedures require the presence of an anesthesiologist.We did not observe any complications in these 15 patients.CONCLUSION:This method is more demanding than standard endoscopic retrograde cholangiopancreatography due to altered postsurgical anatomy.However,it is effective,safe,and widens the possibilities of resolving biliary pathology. | Bohuslav Kianika Jan Lata Ivo Novotny Petr Dítě Jirí Vaníek | 2013 | World Journal of Gastroenterology2013，19，44： | 2 |
