Epidemiology and Diagnosis of Acute Nonvariceal Upper Gastrointestinal Bleeding

Acute upper gastrointestinal bleeding (UGIB) is a common gastroentero-logical emergency. A vast majority of these bleeds have nonvariceal causes, in particular gastroduodenal peptic ulcers. Nonsteroidal anti-inflammatory 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.
