A vast majority of these bleeds have nonvariceal causes, in particular gastroduodenal peptic ulcers. Nonsteroidal antiinflammatory drugs, low-dose aspirin use, and Helicobacter pylori infection are the main risk factors for UGIB. Current epidemiologic data suggest that patients most affected are older with medical comorbidit. Widespread use of potentially gastroerosive medications

underscores the importance of adopting gastroprotective pharamacologic strategies. Endoscopy is the mainstay for diagnosis and treatment of acute UGIB. It should be performed within 24 hours of presentation by skilled operators in adequately equipped settings, using a multidisciplinary team approach. Andrew C. Meltzer and Joshua C. Klein The established quality indicators for early management of upper gastrointestinal (GI) hemorrhage are based on rapid diagnosis, risk stratification, and early management. Effective preendoscopic treatment Y-27632 cell line may improve survivability of critically ill

patients and improve resource allocation for all patients. Accurate risk stratification helps determine the need for hospital admission, hemodynamic monitoring, blood transfusion, and endoscopic hemostasis before esophagogastroduodenoscopy (EGD) via indirect measures such as laboratory studies, physiologic data, and comorbidities. Early management before the definitive EGD is essential to improving outcomes for patients with upper GI bleeding. Yidan Lu, Yen-I Chen, and Alan Barkun This review discusses the indications, selleck chemicals llc technical aspects, and comparative effectiveness of the endoscopic treatment of upper gastrointestinal bleeding caused by peptic ulcer. Pre-endoscopic considerations, such as the use of prokinetics and timing of endoscopy, are reviewed. In addition, this article examines aspects of postendoscopic care such as the effectiveness, dosing, and duration of postendoscopic proton-pump inhibitors, Helicobacter pylori

testing, and benefits of treatment in terms of preventing rebleeding; and the use of nonsteroidal anti-inflammatory drugs, antiplatelet agents, and oral Fenbendazole anticoagulants, including direct thrombin and Xa inhibitors, following acute peptic ulcer bleeding. Eric T.T.L. Tjwa, I. Lisanne Holster, and Ernst J. Kuipers Upper gastrointestinal bleeding (UGIB) is the most common emergency condition in gastroenterology. Although peptic ulcer and esophagogastric varices are the predominant causes, other conditions account for up to 50% of UGIBs. These conditions, among others, include angiodysplasia, Dieulafoy and Mallory-Weiss lesions, gastric antral vascular ectasia, and Cameron lesions. Upper GI cancer as well as lesions of the biliary tract and pancreas may also result in severe UGIB. This article provides an overview of the endoscopic management of these lesions, including the role of novel therapeutic modalities such as hemostatic powder and over-the-scope-clips. Louis M.
