Active clinical trials for "Gastric Antral Vascular Ectasia"

The purpose: To determine the safety and efficacy of Radiofrequency Ablation (RFA) HALO Ultra system in patients with Gastric Antral Vascular Ectasia patient cohort (GAVE). Research design: This is a prospective observational study. Procedure Used: Radiofrequency Ablation Risks and potential benefits: There are no risks associated with this study as it is a retrospective chart review. Potential benefits include the knowledge gained from this study which may be of help to patients in the future. Importance of knowledge that may reasonably be expected to result The knowledge gained from this study may be of help to other patients in the future.

overall aim: To compare the efficacy and safety of endoscopic band ligation and endoscopic argon plasma coagulation for the management of gastric antral vascular ectasia. Secondary aims: Study risk factors of GAVE. Prevalence of GAVE among causes of non-variceal gastrointestinal bleeding.

We will evaluate all out-patients and in-patients with cirrhosis, who undergo upper gastrointestinal endoscopy (EGD) in the Department of Hepatology, Institute of Liver and Biliary Sciences (ILBS), for inclusion. Patients with cirrhosis, with age >18-years, who have characteristic findings of GAVE on endoscopy will be included in this study. Their clinical and biochemical features, and endoscopy findings will be compared with a gender and age-matched control group of cirrhosis without GAVE. This observational, case-control study will aim to define the predictors of GAVE in patients with cirrhosis.

Gastric antral vascular ectasia (GAVE) is a condition that can lead to blood loss in the gastrointestinal tract and low blood counts or anemia. 1,2 GAVE is commonly associated with liver disease, kidney disease and autoimmune immune problems, but can also be seen in patients without those problems. 2-4 It is common for GAVE to cause hospitalization of patients and significant blood transfusion requirements. Given these problems, effective treatment of GAVE is needed to reduce these potential problems. These treatments are performed by a gastroenterologist through a flexible endoscope most often with argon plasma coagulation (APC).5-7 APC is only partially successful at eradicating GAVE and often entails repeated endoscopic procedures. Therapy with APC can also cause ulceration at times resulting in acute bleeding. Cryoablation is an attractive alternative to APC as it should not cause increased blood loss and case reports suggest that ablation may be achieved with limited number of endoscopic sessions. Prior problems with endoscopic cryotherapy include the high flow of gas and risk of perforation.8,9 A recent retrospective investigation by this group has evaluated the first generation cryotherapy balloon, demonstrating clinical safety and efficacy for GAVE.10 A new balloon cryotherapy spray device was recently developed and does not require venting. In this study we plan to prospectively evaluate the use of balloon cryotherapy to treat GAVE. We predict that the therapeutic response of balloon cryotherapy will be greater than 80% effective at achieving clinical success or the loss of overt bleeding and need for packed red blood cell (PRBC) transfusion at 6 months after treatment.

Background: Repeated episodes of bleeding from gastrointestinal vascular malformations refractory to endoscopic or surgical therapy often pose a major therapeutic challenge. Methods: The investigators performed a randomized, parallel controlled study of thalidomide as a therapy for recurrent gastrointestinal bleeding due to vascular malformation. Patients with at least six episodes of bleeding in the prior year due to vascular malformation were randomly grouped, prescribed a four-month regimen of either 25 mg of thalidomide or 100 mg of iron orally four times daily, and monitored for at least one year. The primary end point was defined as the patients whose rebleeds decreased from baseline by ≥ 50% at 12 months and the cessation of bleeding. Rebleeding was defined based on a positive fecal occult blood test (FOBT) (monoclonal colloidal gold color technology) at any visit after treatment. Secondary outcomes included the participants dependent on blood transfusions and changes from baseline in transfused packed red cell units, bleeding episodes, bleeding durations, and hemoglobin levels at 12 months. Statistical significance was defined at P < 0.05.

The investigators goal is to compare the standard argon plasma coagulation (APC) treatment with endoscopic band ligation (EBL) in patients with Gastric Antral Vascular Ectasia.

the study aims to evaluate the role of similar technology of Narrow Band Imaging VIST video intelligent staining technology in the diagnosis of Gastric Antral Vascular ectasia in cirrhotic patients
