目的    总结手术治疗在消化道出血中的应用价值和治疗效果。 方法    对2007年1月至2009年12月中国人民解放军总医院普通外科收治的49例消化道出血病人进行回顾性分析。结果    术前明确诊断36例，无法明确诊断13例。49例均接受外科治疗，围手术期病死率12.24%（6/49）。术前明确诊断和无法明确诊断的病死率分别为5.56%（2/36）和30.76%（4/13，P=0.036），术前明确诊断组和未明确诊断组病死率差异有统计学意义。
结论    术前明确诊断是提高消化道出血外科治疗效果、降低病死率的关键。

Results    All cases were divided into two groups according to whether the etiology is clear or not. Thirty-six cases were belongs to the group of preoperative determined etiology and 13 cases belongs to the group of unknown in etiology. All the cases were performed surgical procedure. The perioperative mortality of gastrointestinal hemorrhage in the study was 12.24% (6/49), and that of the two group was 5.56% (2/36) and 30.76% (4/13) respectively. There was significant difference in the mortality between the two groups (P=0.036). Conclusion    Evidence from the series of cases suggests that preoperative definited diagnosis is the key to improving the curative effect and reducing the incidence of complication in perioperative period.
