Filter by:The investigators establish a randomized controlled clinical trial, comparing the efficacy and prognosis of GVL and GVO in secondary prevention of GVs, especially in patients with portosystemic shunting, and exploring the endoscopic treatment selection of different types of GVs. Outcome expectations: Compared with glue injection, endoscopic ligation for secondary prevention of gastric varices is safe and effective, especially in patients with portosystemic shunting.
The primary objective of the study is to demonstrate the superiority of an "early tips" strategy over standard treatment by glue obliteration (G0) in preventing bleeding recurrence or death at one year after a non GOV1 gastric variceal bleeding in cirrhotic patients initially treated by GO.
A single-center randomized controlled study comparing endoscopic or interventional therapy guided by the hepatic venous pressure gradient (HVPG) , to standard endosopic variceal ligation plus nonselective beta-blocker therapy (NSBB) in patients with esophageal varices due to liver cirrhosis with a history of esophageal variceal hemorrhage.Primary study outcome of the study is variceal rebleeding episodes occurring within the first years after interventions. Second study outcomes of the study are hepatic encephalopathy occurrence, mortality occurrence, liver transplantation or other cirrhosis-related complications.
Non-selective beta blockers are commonly used drugs for primary prevention and secondary prevention in patients with cirrhotic decompensated esophageal varices bleeding，the basic heart rate, blood pressure and condition of different patients have individual differences.This paper mainly discusses the compliance of patients taking NSBB under different follow-up methods and analyze the factors affecting patient compliance.
This study evaluates the safety and efficacy of 24-hour vs 72-hour octreotide infusion after variceal banding in cirrhotic patients with bleeding esophageal varices.
Liver cirrhosis is caused by chronic liver diseases, varices exist in 30 - 60% of patients with liver cirrhosis. Variceal bleeding is one of the most important complications of cirrhosis, accelerating the progression of decompensation to a stage at which the patient is at an extremely high risk of death. Endoscopy is the gold standard for the diagnosis of varices, However, periodic endoscopic screening in all cirrhotic patients might unnecessarily induce an invasive and expensive procedure, ultimately increasing not only the medical workload of endoscopy units, but also the financial burden of patients. To avoid unnecessary endoscopy in low- risk patients, some simple, non-invasive and accurate tests have been developed to identify EVs. Such as Transient elastography (TE) , which is a noninvasive tool that measures liver stiffness (LS) correlating to liver fibrosis stage. Moreover, the LS-spleen size-to-platelet ratio score (LSPS), which is a combination of three simple examination methods (LS, spleen size and platelet count) has been established to accurately predict EVs in patients with cirrhosis. Therefore, investigators design this cross-sectional study to assess these non-invasive tests in predicting the presence of EVs in patients with cirrhosis.
Background: Standardization and new therapeutic treatments of variceal bleeding has significantly reduced the mortality the last 25 years, but there is still a high 6-week mortality around 15-20% and 1-year mortality of about 40%. Cirrhotic patients without prophylactic treatment suffer a risk of 60% of re-bleeding within the first year after the first bleeding episode. Variceal ligation and NSBB are the standard therapy as secondary prophylaxis, while only non-selective beta-blocker (NSBB) is offered as first-line therapy in primary prophylaxis. If portal pressure is reduced to a value below 12 mmHg or by 20% (10% if assessed by intravenous administrations), the risk of bleeding is substantially reduced, but not all patients respond to the treatment with propranolol (40-50%). Hence, patients who are non-responders to NSBB should be offered alternative treatment with e.g. carvedilol, which is a combined alpha-beta-receptor blocker or endoscopic band ligation. Currently, the response to NSBB is assessed invasively during a liver vein catheterization (LVC). Unfortunately, only a few centres in the world can perform this procedure and there are no reliable non-invasive alternatives to assess the respond to NSBB, which is of extreme importance, since non-responders have three fold increased risk of a new variceal bleeding episode. Aim: In general the aim of the project is to develop faster and non-invasive methods to evaluate portal hypertension and individual pharmacological response of NSBB in patients with cirrhosis. Furthermore, we expect to detect changes in liver and spleen stiffness as measured by MR-Elastography (MRE) after NSBB and that these depend on the drug-related effects on portal pressure. Study design and patients: 39 patients with cirrhosis and esophageal varices that require NSBB (propranolol) treatment. Patients are assessed with LVC, MR-scans, echocardiography and biochemical tests. LVC is the gold standard method to test if patients respond to propranolol treatment. At visit 1. the response to NSBB is defined as a reduction of HVPG ≥10%, or to a HVPG< 12mmHg after intravenous NSBB administrations during LVC. MRI-scan with intraveneus NSBB administration is performed at visit 2. Minimum 5 days of NSBB wash out between visit 1 and 2.
Endoscopic Injection Sclerotherapy vs N-butyl-2-cyanoacrylate Injection
Esophageal varices (EVs) resulting from portal hypertension are a prevalent complication of cirrhosis with a high mortality when variceal hemorrhage (VH) occurs. Screening endoscopy for EVs is recommended for all patients with cirrhosis, and prophylactic treatments are proposed for preventing VH, which may be financially onerous. Therefore, noninvasive tools for diagnosing EVs and risk stratifying VH in cirrhotic patients are needed to decrease the number of unnecessary invasive endoscopic examinations of low-risk patients and avoid unneeded prophylactic treatment. This is a prospective, multi-center diagnostic trial conducted at 9 high-volume liver centers in China designed to determine the diagnostic performance of radiomics-based surrogate (rEndosc) (investigational technology) by CT imaging for noninvasive prediction of EVs and risk stratification of VH in patients with hepatitis B virus-related cirrhosis using endoscopic examinations as reference standard.
INTRODUCTION: Bleeding from gastric varices (GV) is associated with a high mortality rate. Injection of cyanoacrylate (CYA) using standard gastroscope has demonstrated to achieve higher hemostasis and lower rebleeding rates compared to band ligation or sclerotherapy. Nevertheless CYA treatment is known to be associated with significant adverse events. Pulmonary embolism due to CYA injection is a serious and sometimes fatal complication of this therapy. These patients usually have respiratory symptom, however this complication can be present in asymptomatic patients, being demonstrated only by a pathological CT scan. On the other hand, it has been described that the risk of glue embolism dependent on the volume of CYA injected, being significantly greater with high volumes. Other complications related to CYA injection are hemorrhage from injection site ulcers, fever, peritonitis, needle impaction, and even death. Also the injection material can cause serious damage to the endoscope. Currently, endoscopic injection of CYA can be performed by direct visualization using a standard gastroscope or guided by Endoscopic Ultrasound (EUS) with injection of CYA alone or in combination with coils. The injection of coils in conjunction with CYA may reduce or eliminate the risk of glue embolization as coils can function as a scaffold to retain CYA within the varix and may decrease the amount of glue injection needed to achieve obliteration. It has been previously demonstrated that treatment under EUS guidance may have some benefits. It allows a precise targeting of the varix lumen or afferent feeding veins, being the vessel obstructed with less amount of CYA than used for the "blind" injection by standard endoscopy, reducing the risk of glue embolism. EUS can confirm varix obliteration by Doppler effect and also the visualization of GV is not impaired by blood or food in the stomach, thus it can be used in the setting of active hemorrhage.
