Filter by:To determine if carvedilol reduces the rate of variceal haemorrhage in patients with cirrhosis and small oesophageal varices
Non-selective beta blockers are commonly used drugs for primary prevention and secondary prevention in patients with cirrhotic decompensated esophageal varices bleedingļ¼the 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.
Assessment of blood ammonia level as a non-invasive predictor for presence of EV and risk of bleeding
Balloon-occluded retrograde transvenous obliteration (BRTO) has been effective method to manage gastric varices. However, more than one third of patients after BRTO treatment experienced worsening of esophageal varices. The present study was designed to evaluate the effect of post-BRTO propranolol adminstration on the change of esophageal varices.
Aim: To test if MRI can detect meaningful changes in portal pressure in the liver to assess whether treatment with beta-blockers has worked. Liver Disease: Most people with liver disease do not have symptoms. Over time they develop 'cirrhosis' - severe liver scarring. In the United Kingdom deaths due to cirrhosis have doubled over the last decade, because of increasing rates of alcohol consumption and obesity, while heart, kidney, lung diseases, strokes and cancer fatalities have fallen. Portal pressure: Cirrhosis causes increased pressure within the liver and changes in the circulation leading to the development of varicose veins in the gullet and stomach called 'varices'. Varices bleed easily, leading to emergency situations that can be life threatening. However, if the increased pressure within the liver (portal pressure) is detected early, then treatment can prevent variceal bleeding. The only test we have to predict prognosis and treatment success in someone with cirrhosis is by measuring the portal pressure. Measuring portal pressure: Currently the only existing test to measure portal pressure is to pass a pressure sensor through a vein in the neck, down into the liver. This is called the hepatic venous pressure gradient (HVPG) measurement. The HVPG measurement is disliked by patients because it is an invasive procedure. It is also expensive and not widely available. Hence, patients with cirrhosis need to have regular camera tests (endoscopies) to look for varices. How can you treat varices? Two options; 1. With tablets to lower the pressure (beta-blockers) 2. Endoscopy treatment (banding) Both have advantages and disadvantages; - Beta-blockers only lower the portal pressure in about half of those that take them, with some evidence they may also have a protective effect against infections from the bowel by increasing the speed of bowel motion - Treating the varices with endoscopy requires several endoscopies and can lead to life-threatening bleeding. Most patients are therefore given beta-blockers and monitored closely to see if they work. Why does it matter? Beta-blockers can cause side effects (e.g. fainting) that are unpleasant enough to make up to one third of patients stop taking them. Beta-blockers only reduce the portal pressure in half of patients. The remaining patients are exposed to potential side effects and possible harm in those with the most advanced liver disease. These patients may still have a life-threatening bleed as the varices have not been adequately treated. There is a desperate need to discover whether the portal pressure changes with treatment (such as with beta-blockers) without invasive tests across the NHS. Proposed study: Researchers in Nottingham have shown MRI can be used as an accurate marker of portal pressure with just one scan. To be useful to patients, doctors and researchers, this study will investigate whether MRI can detect meaningful changes in portal pressure after treatment with beta-blockers. This study has been designed with patient and public involvement (PPI) integrated throughout. A focus group shaped the study design and committed to collaborate in developing patient materials, recruitment, retention and dissemination. All patients who have HVPG will be given information about the study. Study Visit 1 - One hour MRI scan - Endoscopy to identify varices - If varices are present the patient will be started on beta-blockers and invited to visit 2 - If there are no varices, patients will return to regular follow up with the liver team Study Visit 2 (after one week) - Assess side effects, blood pressure and pulse - Increase dose of beta-blocker as appropriate Study Visit 3 (after 4-12 weeks) - One hour MRI scan - Repeat HVPG measurement Treatment success is determined by the second HVPG measurement. If beta-blockers are working they will be continued. If not, the patient will have treatment with endoscopy. This represents the ideal pathway which is more personalised than current standard care.
The purpose of the study is to evaluate the efficacy of Rifaximin in the treatment of cirrhotic gastroesophageal variceal bleeding.
To observe the Safety and Efficacy of Compont Medical Glue in the Treatment of Esophagogastric Varices.
To date, there is no treatment strategies for these patients according to American Association of the Study of Liver Disease (AASLD) practice guidelines and Baveno V consensus. Thus, we aim to compare the safety and efficacy of TIPS and conservative treatment (non-selective beta blockers, endoscopic therapy and/or anticoagulation) in patients with PVT and CPTV.
Esophageal variceal bleeding is a severe complication of portal hypertension. Banding ligation plus non-selective beta-blockers is the current recommendation for prevention of recurrent bleeding. However, the optimal duration of use of non-selective beta-blockers is not well defined. This study aims at comparing the rebleeding rate and adverse effects in patients using or without using propranolol after eradication of esophageal varices.
