Upper gastrointestinal bleeding (UGIB) is gastrointestinal bleeding in the upper gastrointestinal tract, commonly defined as bleeding arising from the esophagus, stomach, or duodenum. Blood may be observed in vomit or in altered form as black stool. Depending on the amount of the blood loss, symptoms may include shock.
Patients aged 80 years or more may be especially susceptible to bleeding complications, with a rate of 13 bleeds per 100 person-years. [49] This bleed rate would seem to preclude use of warfarin; however, a randomized controlled trial found benefit in treating patients 75 years or over against aspirin with a number needed to treat of 50.

An upper GI bleed is more common than lower GI bleed. [2] An upper GI bleed occurs in 50 to 150 per 100,000 adults per year. [8] A lower GI bleed is estimated to occur in 20 to 30 per 100,000 per year. [2] It results in about 300,000 hospital admissions a year in the United States. [1] Risk of death from a GI bleed is between 5% and 30%.
[3] [6] Chronic disease is a risk factor for acute disease. [7] The best method of diagnosis is angiography, with computed tomography (CT) used when that is not available. [1] Treatment of acute ischemia may include stenting or medications to break down the clot provided at the site of obstruction by interventional radiology. [1]
Blood in stool looks different depending on how early it enters the digestive tract—and thus how much digestive action it has been exposed to—and how much there is. The term can refer either to melena, with a black appearance, typically originating from upper gastrointestinal bleeding; or to hematochezia, with a red color, typically originating from lower gastrointestinal bleeding.

Commonly the embolism is caused by atrial fibrillation, valvular disease, myocardial infarction, or cardiomyopathy. [ citation needed ] In addition, ischemic colitis is a well-recognized complication of abdominal aortic aneurysm repair, when the origin of the inferior mesenteric artery is covered by the aortic graft.

The symptoms vary from the severity of the disorder. The most classic sign of AEN is the dark pigmentation of esophageal mucosa in an upper endoscopy, usually viewed as an ulcer or as an infectious disease. [6] Necrosis can be found mostly between the three distals of the esophagus, but stops abruptly at the gastroesophageal junction. [2]
