Active clinical trials for "Esophageal and Gastric Varices"

Randomized comparison within the endoscopic esophageal varices ligation versus non-selective beta-blocker in the primary prevention of esophageal variceal bleeding in patients with HCC.

Design a randomized trial to compare the effect of endoscopic cyanoacrylate injection obliteration versus non-selective beta-blocker in the primary prevention of gastric variceal bleeding.

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.

The purpose of this study is to study the efficacy of endoscopic cyanoacrylate injection versus balloon-occluded retrograde transvenous obliteration in the prevention of gastric variceal 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.

We design a randomized trial to clarify the necessity of antibiotic prophylaxis for the patients chronic liver disease with gastric varices treated by elective GVO.

Research has proven that large varices can be treated with beta-blockers (a type of anti-hypertensive medication) to reduce the pressure in the veins. The management of small varices is still uncertain. This study aims to discover if beta blockers can be used in this setting. We hypothesize that beta blockers will reduce the risk of bleeding from small varices from 20% to 10% over a period of 3 years, resulting in significant cost savings to the NHS from better patient outcomes.

To determine if carvedilol reduces the rate of variceal haemorrhage in patients with cirrhosis and small oesophageal varices

A prospective, randomized controlled study on whether re-education after discharge can reduce the rebleeding rate after endoscopic treatment of esophageal and gastric varices in patients with liver cirrhosis

The goal of this exploratory validation study is to compare levels of expertise (or non-expertise) between GI fellows and experts with the varix trainer. The main question it aim to answer is: Can the varix trainer distinguish levels of expertise (or non-expertise) between novices and experts for specific skills (torque, small wheel and retroflexion techniques)? Does the training with the varix trainer improves these specific skills of GI fellows? Participants will do the pre-training test, practicing eight-sessions (each session is approximately 15minutes) and then do the post-training test.
