Active clinical trials for "Gastrointestinal Hemorrhage"

Acute Gastrointestinal (GI) Bleeding are a common chief complaint among Emergency Department. The mortality rate for Lower GI Bleeding is 3.9%. While the mortality rate can be as high as 10% for Upper GI Bleeding. Most existing scores take into account hemodynamic parameters such as systolic blood pressure or heart rate. Studies have shown that hemodynamic instability only develops late in the course of a bleed, as evidenced by a blood depletion of 30 to 40% of the total blood volume. Currently, few studies have examined the value of echocardiography in the management of patients presenting for Acute GI Bleeding in the Emergency Department. The main objective of this study is to show whether simple ultrasound parameters can, combined with clinico biological parameters, predict in an early manner the evolution of the patient presenting to the Emergency Department for Acute Gastrointestinal Bleeding.

Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.

Hp infection is closely related to upper gastrointestinal bleeding in patients who need dual-antiplatelet after PCI. Taking anti-Hp treatment has the effect of reducing bleeding risk. Thus, we propose a scientific hypothesis: the C13 breath test may be used to assess the risk of upper gastrointestinal bleeding in patients who need dual- antiplatelet after PCI.

The rate of complication and death of patients with acute digestive tract bleeding is increased in the setting of acute coronary heart disease. The aim of the study is to establish the relative importance of the risk factors contributing to the death rate from acute digestive tract bleeding in patients admitted with acute coronary heart disease.

Up to 5% of patients with recurrent gastrointestinal (GI) bleeding remain undiagnosed by EGD and colonoscopy, the presumed source of bleeding in these patients being the small intestine. These patients fall under the category of "obscure gastrointestinal bleeding," and frequently require an extensive diagnostic work-up. For these reasons, most patients who present with obscure or occult gastrointestinal bleeding typically undergo multiple endoscopic evaluations, including capsule endoscopy and various radiologic imaging studies, including enteroclysis, small bowel series, CT scan, angiography, and radionuclide scan. Recently, many centers (included the Brigham and Women's Hospital) have begun using capsule endoscopy and CT enterography (CTE) for evaluation of suspected small bowel pathology. This is an observational study enrolling patients referred to the Brigham and Women's Hospital for obscure gastrointestinal bleeding designed to compare the diagnostic yield of various diagnostic modalities, in particular capsule endoscopy and CT enterography in the evaluation of obscure gastrointestinal bleeding.

The purpose of this study is to assess gastroprotective agent compliance in patients at risk suffering from a gastrointestinal bleeding ulcer or a symptomatic ulcer with NSAID.

The hypothesis is that the mortality of patients with non-varicose upper gastrointestinal bleeding after performing early gastroscopy who are admitted on weekends and night hours is higher than those admitted on weekdays or during daytime hours.

Gastrointestinal bleeding represents a serious clinical problem and a common cause of hospitalisation with a mortality rate of 6-10% for upper Gastrointestinal bleeding and of 4% for lower Gastrointestinal bleeding requires a multidisciplinary approach involving gastroenterologists, endoscopists, surgeons and radiologists. Gastrointestinal bleeding is self-limited in 80% of cases requiring only supportive measures. However, the persistence of bleeding represents a diagnostic challenge to locate the site of bleeding especially in severe bleeding and to determine, if possible its cause. This will allow to select the most appropriate therapeutic approach in order to reduce the morbidity and mortality, the length of hospitalisation and the transfusion requirements. Current diagnostic algorithms vary widely from institution to institution and from clinician to clinician. Imaging modalities remain the mainstay of the diagnostic approach. They include endoscopy, video capsule, radionuclide imaging, catheter angiography and multidetector computed tomography imaging. In recent years, Multidetector computed tomography has emerged as a promising technology to evaluate Gastrointestinal bleeding. The modality's ease of use and rapid results favour its use in any emergent situation. In addition, today's high-speed, narrow collimation multi-detector technology allows a large coverage area with minimal motion artifacts, with the ability to capture both arterial and venous phase with ease. Multidetector computed tomography is being increasingly used as this is a widely available, non-invasive and fast diagnostic technique that allows for visualisation of the entire intestinal tract and its lesions, the identification of vascularity and possible vascular abnormalities.

Cross sectional case-control study investigating the difference of volatile organic compound in the exhaled breath of the patients with GI bleeding and normal population.

Unlike the management of patients with various forms of accidents (e.g. polytrauma), only a few data exists for the emergency management of patients with acute gastrointestinal bleeding. The aim of our study is to develop optimal diagnostic and therapeutic algorithms for the management of acute upper and lower gastrointestinal bleedings.
