Etiology and Outcome of Acute Gastrointestinal Bleeding in Iran: A Review Article
Abstract
Upper gastrointestinal bleeding (UGIB) is defi ned as bleeding that results from lesions located above the ligament of Treitz and is a common cause for emergency hospital admissions in patients with gastrointestinal disorders. UGIB also increases the risk of morbidity and mortality in patients already hospitalized for other reasons. According to epidemiological surveys of acute UGIB in Iran, peptic ulcer is the most common endoscopic diagnosis. Gastric and duodenal erosion accounts for 16.4%-25% of etiologies. Other relatively common causes of UGIB are variceal hemorrhage, Mallory-Weiss tears, and arterial and venous malformations. However, in 9%-13.3% of patients, the endoscopy is normal.
