Filter by:High intravenous dosage of Proton Pump Inhibitors is not better than standard dosage in bleeding peptic ulcers successfully treated by endoscopic therapy
Gastric lavage is usually used for gastric preparation before endoscopy in patients with upper gastrointestinal bleeding. However, the benefit-risk balance of putting a nasogastric tube in these patients is not clearly defined. This randomized trial is aimed to determine if the use of erythromycin IV before endoscopy could avoid to put a gastric tube for the management of upper gastrointestinal bleeding.
This study is being carried out to see if constant 3 days infusion of Nexium is effective in preventing rebleeding after an endoscopic treatment.
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
The purpose of this study is to conduct a cost-effectiveness analysis of wireless capsule endoscopy in the investigation of patients with overt obscure gastrointestinal bleeding. To inform this analysis, a randomized controlled trial of capsule endoscopy compared with standard care will be conducted
Gastrointestinal bleeding is a severe adverse effect occurring in subjects secondary to the use of nonsteroidal anti-inflammatory drugs (NSAIDs). The enzyme CYP2C9 is responsible for the elimination of several NSAIDs. This protein is inactive in 12% of the subjects because of genetic mutations. We hypothesized that individuals carrying such mutations should be at higher risk of gastrointestinal bleeding since they display decreased NSAIDs elimination.
To evaluate if intravenous PPI infusion, when administered prior to endoscopy, hastens resolution of bleeding stigmata and thereby facilitates endoscopic examinations and reduces the need for endoscopic treatment. Clot stabilization may itself sustain control of bleeding before endoscopy. These may translate into improved patients’outcome and survival. To determine the therapeutic effect of high-dose PPI infusion in upper gastrointestinal bleeding from causes other than peptic ulcers.
To evaluate the incidence and etiology of small bowel or large bowel bleeding in patients presenting with melena.
To compare the diagnostic yield of mesenteric angiogram with CE in patients with active obscure GIB.
To assess the efficacy and safety of the early administration of somatostatin in infusion during 72 hours plus 2 boluses, compared to placebo in the control of acute severe UGIB with suspicion of PUB.
