Bleeding may occur at any site of the digestive (gastrointestinal) system from the mouth to the anus, and presenting the leakage of blood from the vascular space. It can occur as blood in the stool or vomit content, and may also be hidden (occult)-which can be detected by testing. Bleeding anywhere in the gastrointestinal tract may intensify and result in a second bleeding disorder. Possible symptoms include vomiting blood (hematemesis), passage of black stools (melena) and the passage of visible blood from the rectum (hematochezia). Black tarry stools are typically caused by bleeding in higher parts of the digestive system as the stomach and duodenum. Bleeding from the gastrointestinal tract is a serious medical condition, and is often a reason for hospital admission. This results in high morbidity and high costs of treatment. The incidence of gastrointestinal bleeding in developed countries ranges between 103-172/100.000 inhabitants per year, of which approximately 50% involve bleeding from the upper gastrointestinal tract. Despite revolutionary advances in endoscopic diagnosis and therapy, as well as pharmacological therapy, the frequency of certain types of bleeding from the upper gastrointestinal tract are increased, though mortality continually remains at the same level as the ‘70s of the 20th century-, all of which is associated with the aging population, higher co-morbidity, the wide spread use of NSAIDs and anticoagulants and the high incidence of liver cirrhosis. Although the observed is a decreased in the incidence of bleeding, there is no reduction in the mortality rate or the occurrence of re-bleeding. It is assumed that the reason lies in the aging population and associated diseases. Through circumstances it is necessary to find predictive tools such as Glasgow and Blatchford’s and Rockall’s scoring system, which would be in patients with bleeding from the upper gastrointestinal tract helping determine how much endoscopic treatment and hospitalization is required.
