Active clinical trials for "Esophageal and Gastric Varices"

Prospective investigations into the role of hemostatic factors in the risk of variceal bleeding among children with chronic liver disease (thromboelastometry e.g) is still required. A better understanding of these factors would permit better risk stratification and targeted prophylaxis or therapy.

We will include patients with EV and EVB. They will be randomized to EVL vs. NSBB for primary prevention And EVL+long-term NSBB vs. EVL+short-term NSBB for secondary prevention. 150 patients will be included in a 3-year period. Primary end-points are formation/progression of ascites, acute kidney injury and survival. The other outcomes such as bleeding, rebleeding, infection and other risk factors will be also analyzed.

The purpose of this study is to assess whether the add of Rifaximin in patients with liver cirrhosis and esophageal varices treated with a standard therapy with beta blockers, leads to a significant reduction of portal hypertension.

This prospective randomized controlled trial will compare endoscopic band ligation (EBL) with propranolol and EBL alone in primary prophylaxis of variceal bleeding among cirrhotic patients with high-risk varices.

Optimal time for follow up after variceal band ligation in cirrhotic patients remains to be determined

Endoscopic Injection Sclerotherapy vs N-butyl-2-cyanoacrylate Injection

To compare the efficacy and safety of Carvedilol and Propranolol in patients with cirrhosis-related esophagogastric varices after multiple endoscopic treatments for secondary prophylaxis.

Patients with cirrhosis require endoscopic screening for large esophageal varices. The aims of this study were to determine the cost -effectiveness and patient preferences of a strategy employing abdominal computerized tomography (CT) as the initial screening test for identifying large esophageal varices. In a prospective evaluation,102 patients underwent both CT and endoscopic screening for gastroesophageal varices. Two radiologists read each CT independently; standard upper gastrointestinal endoscopy was the reference standard. Agreement between radiologists, and between endoscopists regarding size of varices was determined using kappa statistic. Cost-effectiveness analysis was performed to determine the optimal screening strategy for varices. Patient preference was assessed by questionnaire. CT was found to have an approximately 90% sensitivity in the identification of esophageal varices determined to be large on endoscopy, but only about 50% specificity. The sensitivity of CT in detecting gastric varices was 87%. In addition, a significant additional number of gastric varices, peri-esophageal varices, and extraluminal pathology were identified by CT but not identified by endoscopy. Patients overwhelmingly preferred CT over endoscopy . Agreement between radiologists was good regarding the size of varices (Kappa = 0.56), and exceeded agreement between endoscopists (Kappa = 0.36). Use of CT as the initial screening modality for the detection of varices was significantly more cost-effective compared to endoscopy irrespective of the prevalence of large varices. In conclusion, abdominal CT as the initial screening test for varices could be cost-effective. CT also permits evaluation of extra-luminal pathology that impacts management.

The purpose of the study is to evaluate the efficacy and safety of prophylactic use of antibiotics in endoscopic injection of tissue adhesive in gastric varices.

Aim of this thesis is to predict the incidence of esophageal ulcer bleeding after endoscopic management of esophageal varices. This study will be in the department of Tropical Medicine and Infectious Diseases, Tanta University, in at least six months in the period from august 2014 to march 2015 or until the target number of patients reached whichever is longer.
