Upper gastrointestinal bleeding (UGIB) is a common problem with an annual incidence of approximately 80 to 150 per 100,000 population, with an estimated mortality rate of 2% to 10%. UGIB is classified as any blood loss from a gastrointestinal source in the esophagus, stomach, or duodenum; historically defined as above the ligament of Treitz, a fibromuscular band extending from the upper surface of the duodenojejunal junction. UGIB can manifest as hematemesis, be it bright red or coffee-ground emesis, hematochezia, or melena. Patients may also present with systemic symptoms secondary to blood loss, such as orthostasis, syncope, fatigue, and weakness. Prior data from the United States show that UGIB accounts for nearly 40% of hospital admissions for gastrointestinal bleeding, with an estimated annual cost of over 2 billion dollars.
上消化道出血(UGIB)是一个常见问题,年发病率约为每10万人80至150例,估计死亡率为2%至10%。UGIB被定义为食管、胃或十二指肠胃肠道来源的任何失血;历史上定义为屈氏韧带以上,屈氏韧带是一条从十二指肠空肠交界处上表面延伸的纤维肌肉带。UGIB可表现为呕血,可为鲜红色或咖啡渣样呕血、便血或黑便。患者也可能出现失血继发的全身症状,如直立性低血压、晕厥、疲劳和虚弱。美国先前的数据显示,UGIB占胃肠道出血住院人数的近40%,估计每年费用超过20亿美元。
