Active clinical trials for "Gastrointestinal Hemorrhage"

Controlled and randomized study comparing combined treatment (nadolol and endoscopic ligation) versus nadolol associated with isosorbide mononitrate or prazosin according to hemodynamic response, in the prevention of esofagic verices rebleeding.

Upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality in patients with portal hypertension secondary to schistosomiasis mansoni. Taking into account the endemic nature of schistosomiasis mansoni in our region and the high morbidity and mortality directly associated with rupture of esophageal varices and UGIB in affected patients, we conducted a prospective randomized trial in patients with schistosomiasis and a history of bleeding esophageal varices. Its purpose was to assess the efficacy of endoscopic treatment alone compared with the efficacy of sclerotherapy preceded by a surgical treatment: Esophagogastric devascularization with splenectomy (EGDS).

Capsule endoscopy (CE) is a safe and effective tool for the assessment of obscure gastrointestinal bleeding (OGIB). However, its real efficacy and its position in the diagnostic algorithm of OGIB vs. push enteroscopy (PE) remain unknown since in previous studies both techniques were performed in all included patients The purpose of this protocol is to conduct a randomized prospective controlled trial in patients with OGIB comparing a strategy based on CE or PE followed by the alternative exploration only when the first line exploration was negative. The main outpoint of this study concerns the diagnostic yield of the two explorations. Second endpoint concerns the clinical relevance of the two strategies tested (CE ± PE vs. CE ± PE) in terms of diagnostic yield, clinical outcome, therapeutic impact and added explorations

Critically ill patients are at an increased risk of having upper gastrointestinal (GI) bleeding due to stress related mucosal damage. Cimetidine, delivered continuously through intravenous infusion, is the only drug that the FDA has approved for the prevention of upper GI bleeding in critically ill patients. The present trial is intended to assess the safety and efficacy of an omeprazole sodium bicarbonate immediate-release suspension in this indication.

Prospective observational pilot study evaluating the frequency of cow's milk protein allergic prococolitis in newborns hospitalized in neontal medicine at the university hospital of Nice who presented rectal bleeding.

Obscure gastrointestinal bleeding (OGIB) has been one of the most challenging area in the field of gastroenterology, as small bowel is beyond the reach of ordinary endoscopes like oesophagogastroduodenoscopy (OGD) and colonoscopy. Thanks for the latest technological advancement for investigating small intestine, we are now capable of obtaining intraluminal images safely through capsule endoscopy (CE). Its role in obscure gastrointestinal bleeding, Crohn's disease and other small bowel pathologies has already been proven, and nowadays it is suggested by various authorities to be the first-line modality among all small bowel investigations. The investigators group has showed that CE can alter the clinical management of patients with OGIB - patients with negative CE has lower rebleeding rate, and therefore we may adopt a conservative approach for them. Although supported by some other group as well, conflicting results were still reported in the literature about the out-come of these patients. The main criticisms for these studies are that, CE can only identify 61% of the underlying small bowel bleeding pathology, and one can never ascertain the outcome of patients with negative CE examination. Apparently there is still room for improvement in the current CE technology.

Study hypothesis is that performing early colonoscopy in patients who present to the hospital with lower GI bleeding improves their outcome. Patients who are admitted with bleeding from their rectum and a negative endoscopic exam of the stomach and upper intestine are randomized (like flipping a coin) to receive a colonsoscopy either as an emergency (within 12 hours) or as a routine procedure (36 hours after admission). Patients are followed during their hospitalization to see if they have further bleeding, if they require blood transfusions, if they need other diagnostic tests, if they need surgery or other treatments, and how long they stay in the hospital.

Small bowel capsule endoscopy is the main diagnostic standard for small bowel bleeding. This study investigates the detection rate of small bowel bleeding in capsule endoscopy and further endoscopic treatment in a prospective and retrospective cohort.

timely short-term antibiotic prophylaxis is an essential step in the management of these patients . Prophylaxis must be instituted as early as variceal hemorrhage is suspected, and timely administration has been associated with a reduced re-bleeding rate and lower mortality . More recently, the American Association for the Study of Liver Diseases (AASLD), the Department of Veterans Affairs (VA), and the American Society for Gastrointestinal Endoscopy (ASGE) recommended antibiotic prophylaxis in all cirrhotic patients with UGIB, regardless of its source (i.e. variceal or non-variceal) or the presence of ascites.

Upper endoscopy is performed for upper gastrointestinal bleeding (bleeding in the esophagus, stomach, or part of the duodenum) to identify and potentially treat the cause of bleeding. However, blood clots often make visualization difficult during endoscopy. The current practice is to try to wash off and suction up these blood clots with the endoscope. However, this is often not successful due to blood clots blocking the suction channel. A new device has been approved by Health Canada that attaches to the endoscope and helps prevent blockage. It is believed that this device will help doctors suck out blood clots and potentially improve visualization, identification of the cause of bleeding, and possibly health outcomes, although this has never been proven. The purpose of the this clinical trial is to test whether the device works and whether it can help patients with this type of bleeding.
