RESULTS Duodenal ulcer was the first cause of upper gastrointestinal hemorrhage. Gastric ulcer, cirrhosis, Mallory-Weiss syndrome or acute gastric mucous lesion was the second cause of the illness alternatively. The rate of endoscopy and emergent endoscopy has been going up year after year and got up to 80% in 1998. Bleeding and active hemorrhage, respectively were found in 24.3% and 14.9% of the patients underwent endoscopy before medication. Endoscopic hemostasis was performed in 108 patients by spraying hemostatics and a good response was achieved subsequently. Hemostatics were mainly cimetidine and yunnan baiyao before 1994. Reptilase, pPI, famotidine and ranitidine were used increasingly while cimetidine and yunnan baiyao were used decreasingly. Octreotide was used in patients with cirrhosis commonly. The length of hospital stay and the period from admission to bleeding cease tended to be shorter year by year, but the reduction rate was small. The uses of ranitidine, famotidine, pPI, reptilase, octreotide, early endoscopy and endoscopic therapy may play a role in improving the therapeutic effect of hemostasis, reducing the hospitalization and the mortality.

结果 十二指肠球部溃疡是历年上消化道出血的首要原因，胃溃疡、肝硬变、Mallory -Weiss综合征、急性胃粘膜病变则交替成为第2位出血原因；内镜诊断率和急诊内镜率逐年提高，1998年达到80%，内镜下见出血者占内镜检查的24.3%，而见到活动性出血者仅占内镜检查者的14.9%；内镜下止血108例次，成功率100%；1994年前治疗药物主要为云南白药和甲氰咪胍，之后，随着立止血、质子泵抑制剂、法莫替丁、雷尼替丁等药物使用的逐渐增多，前二者的使用逐渐减少，善得定多用于肝硬变出血；住院天数和止血天数呈逐年下降的趋势，但幅度微小；雷尼替丁、法莫替丁、PPI、立止血、善得定的使用以及及时的内镜检查和内镜下治疗在提高止血效果、缩短住院天数、降低死亡率方面可能起到了一定作用。
