Filter by:The aim of this study is to explore whether using endoscopic ultrasound (EUS) to assess gastric varices (GV) and giving additional treatment according to the diameter and blood flow of residual after endoscopic cyanoacrylate injection for GV can reduce the rate of GV rebleeding, mortality, the risk of adverse events, and cost-effectiveness. This study is a multicenter prospective, open-label, randomized controlled study, including 5 study centers: Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The Southwest Hospital of Army Medical University, Affiliated Hospital of Zunyi Medical University and Shanxi Coal Center Hospital. The total sample size is 150 patients, with 75 patients in the EUS evaluation group and 75 patients in the control group, respectively. The patients who meet the inclusion and exclusion criteria are randomly assigned to EUS evaluation group and control group by using block randomization. The EUS evaluation group uses EUS to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for GV to evaluate the embolization effect. Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by EUS. The control group return to the ward after endoscopic cyanoacrylate injection, without EUS evaluation. During the study, the patients are followed up for at least 12 months, and they are requested to return to the hospital for follow-up at 1 month, 3 months, 6 months and 12 months after the treatment, respectively. The data of baseline, treatment, postoperative and follow-up of the two groups are need to collect. The primary outcome of this study is rebleeding rate. Secondary outcomes are eradication rate of GV, mortality rate, retreatment, and cost-effectiveness.
The main purpose of this exploratory study was to investigate the instant efficacy and safety of alverine oral administration in decreasing portal hypertension. Condition of disease: Cirrhotic portal hypertension Intervention/treatment: Drug: Alverine 60 mg (1 capsule), orally Drug: Alverine 120 mg (2 capsules), orally
To evaluate whether atorvastatin can improve portal hypertension in patients with chronic hepatitis B related compensated cirrhosis with portal hypertension
This pilot study to determine the feasibility of EUS-Portal Pressure Measurements to guide Beta-Blocker Therapy in patients with compensated cirrhosis .The study will be a prospective tandem controlled trial consisting of 30 patients who are already undergoing routine endoscopy screening for portal hypertension as part of their routine clinical care . The decision to start a beta-blocker will be made at the conclusion of the EGD based on the endoscopic findings (presence of esophageal varices). EUS-PPG will then be performed and measurements will be collected. The primary outcome is the feasibility of guiding B blocker therapy by EGD+EUS-PPG at the time of EGD for variceal screening. The secondary outcome will be the proportion of patients initiated on beta-blocker therapy based on EGD alone versus EGD+EUS-PPG
How to construct a novel, non-invasive, accurate, and convenient method to achieve prediction of hepatic venous pressure gradient (HVPG) is an important general problem in the management of portal hypertension in cirrhosis. We plan to investigate the ability of AI analysis of Ultrasound, computed tomography (CT) or magnetic resonance (MR) to establish a risk stratification system and perform tailored management for portal hypertension in cirrhosis.
Portal hypertension contributed to the main complications of liver cirrhosis. Currently, hepatic venous pressure gradient (HVPG) was the reference standard for evaluating portal pressure in patients with cirrhosis. However, the practice of HVPG is limited to require the extensive experience and highly specialized centers. In recent years, non-invasive methods were proposed to predict the degree of cirrhotic portal hypertension. Of them, liver stiffness measured by FibroScan had shown good performance for predicting clinically significant portal hypertension. However, the correlation between liver stiffness and HVPG was poor when HVPG was more than 12mmHg. Since the spleen was stiffer than the liver, the current vibration-controlled transient elastography examination is dedicated to the liver, rather than the spleen. Very recently, a novel spleen-dedicated stiffness measured by FibroScan was proposed. The prospective, multicenter study aims to evaluate the correlation between SS (measured by the novel FibroScan) and HVPG, and further develop a novel model based on SS for predicting the liver decompensation in patients with compenstaed cirrhosis.
This study is a prospective, multi-center and observational clinical study. Investigators would like to explore the optimal emergency endoscopy timing in cirrhosis patients with esophagogastric variceal bleeding (EGVB) by evaluating and comparing the efficacy and safety of emergency endoscopy performed at different times ( within 6 hours or between 6 and 24 hours after gastroenterologic consultation ) and its impact on the short-term prognosis.
Complications associated with portal hypertension are the leading cause of death in patients with cirrhosis. Until now, hepatic venous pressure gradient (HVPG) - the difference between the wedged hepatic venous pressure (WHVP) and the free hepatic vein pressure (FHVP)- has been the criterion standard to determine portal pressure. Antiviral therapy may decrease HVPG which needs to be verified.
Transjugular intrahepatic portosystemic shunt (TIPS) could effectively decrease portal hypertension-related complications. This study intends to evaluate the efficacy and safety of TIPS combined with subsequent microwave ablation in HCC patients with refractory ascites.
Myeloproliferative neoplasms (MPNs), including polycythemia vera, essential thrombocythemia, and primary myelofibrosis, may lead to gastroesophageal varices. The quality of life, morbidity, and mortality of MPN patients mainly depend on disease-related symptoms, thromboembolic and hemorrhagic complications. Previous studies have shown that JAK2 V617F has a prominent role in vascular risk and MPN-associated gastroesophageal varices. Portal vein thrombosis and portal cavernoma frequently occur in the MPN population and the management of gastroesophageal varices in these patients are sometimes technically difficult. The aim of this study is to investigate the the characteristics of patients with gastroesophageal varices and portal caver cavernoma with or without JAK2 mutation.
