Upper gastrointestinal bleeding (UGIB) is defined 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.
上消化道出血(UGIB)定义为由屈氏韧带以上部位病变引起的出血,是胃肠道疾病患者紧急住院的常见原因。UGIB还会增加因其他原因已住院患者的发病和死亡风险。根据伊朗急性UGIB的流行病学调查,消化性溃疡是最常见的内镜诊断结果。胃和十二指肠糜烂占病因的16.4%-25%。UGIB的其他相对常见原因包括静脉曲张出血、马洛里-魏斯撕裂伤以及动静脉畸形。然而,9%-13.3%的患者内镜检查结果正常。
