Active clinical trials for "Gastrointestinal Hemorrhage"

The purpose of the study is to evaluate the safety and efficacy of Rifaximin in the treatment of cirrhotic gastroesophageal variceal bleeding.

UI-EWD (NextBiomedical Co, Incheon, South Korea), a new hemostatic powder for endoscopic treatment of high-risk bleeding peptic ulcers and bleeding after ESD/EMR.

Pre-market, multi-center, international, double-blind, randomized, controlled, prospective, first-in-human clinical investigation of a Class IIb Investigational Medical Device, in which Patients presenting with acute upper gastrointestinal hemorrhage (AUGIH) and due to undergo a plasma transfusion, will be randomized to receive a one-time infusion (up to 8 hours) of up to two 250 mL units of plasminogen-depleted plasma (PDP) or fresh-frozen plasma (FFP). In case of transfusions needing more than two units, the third unit and above will consist in regular plasma for both treatment groups. Patients will be continuously monitored for 8 hours following the transfusion, and will be assessed between 8-12 hours after plasma transfusion or the following morning (the earlier of the two options), between 24-48 hours after plasma transfusion or at discharge (the earlier of the two options) and after 30+/-3 days after transfusion.

The purpose of this study is to determine whether Thalidomide is effective in the treatment of arteriovenous malformations in the gastrointestinal tract.

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.

This multi-center, randomized controlled trial study is planned to include 162 outpatients with onset of acute lower gastrointestinal bleeding to compare the rate of identification of stigmata of recent hemorrhage (SRH), and other clinical outcomes, including the 30-day rebleeding rate, between 'early' colonoscopy and 'elective' colonoscopy.

This study evaluates the efficacy of high-dose fish oil in decreasing rates of gastrointestinal bleeding in patients with continuous-flow left ventricular assist devices. Half of the patients without history of bleeding will receive fish oil while the other half will not. Half of the patients with history of bleeding will receive fish oil while the other half will not. Markers of angiogenesis and inflammation, as well as changes in the microbiome will be assessed in each group.

Gastrointestinal bleeding originating from the small bowel is difficult to diagnose and treat because the small bowel is difficult to see and reach. Balloon assisted enteroscopy (BAE) is a new enteroscopy methods that allow examination of the small bowel and allows for diagnosis and treatment of bleeding originating from this part of the intestine. Unfortunately, BAE is unsuccessful in identifying the cause of bleeding in 40-50% of patients. This may be due to limited visualization of the small bowel lining during conventional endoscopy. One way to improve visualization of the small bowel lining is by adding a transparent plastic cap to the end of the endoscope (camera), which allows the endoscope to see around sharp turned and behind folds in the small bowel. The investigators goal in this randomized controlled study is to see if adding a transparent cap to the end of the endoscope will help to identify and treat small bowel bleeding. The investigators will invite patients referred for BAE to participate in the study; the alternative to participating in the study is having standard BAE (without a cap). If patients choose to participate in the study they will be randomized to BAE with or without a cap on the end of the endoscope. Subjects time commitment will be limited to the consent process and pre-procedure paperwork at time of initial endoscopy and time required to complete telephone questionnaire at 12 months follow up.

The purpose of this study is to determine whether 40 mg octreotide long-acting release intramuscular every 28 days is effective in the treatment of patients with refractory anemia due to gastrointestinal angiodysplasias. We hypothesize that octreotide is effective in reducing the transfusion requirements (consisting of red blood cell transfusions and intravenous iron infusions) of patients with angiodysplasia-related anemia.

The investigators hypothesize that octreotide LAR (Long Acting Release) safely decreases GI bleeding in patients with a left ventricular assist device (LVAD). Patients undergoing implantation of non-pulsatile, continuous-flow LVAD have a higher incidence of gastrointestinal bleeding. This is a significantly associated morbidity and can threaten a patient's life as well as their ability to undergo eventual heart transplantation secondary to both general health/strength and the potential development of antibodies to blood products that would make future transfusions and transplantations more difficult. If this research finds that use of octreotide LAR can decrease the incidence of gastrointestinal bleeding in this patient population, it will revolutionize the manner in which these patients are managed. The finding of reduced GI bleeding would allow the patient to have less exposure to blood products, reduce hospitalizations, and ensure that subsequent transplant planning not be delayed. This would not only be of great benefit to the patient, but would significantly decrease health-care costs through preventive measures. The goal of this project is to study whether the regular administration of monthly octreotide LAR is safe and if it will decrease the incidence of gastrointestinal bleeding in patients undergoing implantation of non-pulsatile, continuous flow left ventricular assist devices (LVAD).
