目的：明确下消化道出血原因及止血治疗。材料与方法：对21例不明原因下消化造出血病人行选择性血管造影，并经导管灌注垂体后叶素、明胶海绵条栓塞。结果：血管造影诊断阳性率为76％，16例病人治疗后均止血。结论：血管造影是诊断不明原因下消化道出血的首选方法，垂体后叶素灌注短期（1周）止血效果显著，但易复发，栓塞治疗更重要的在于确定病变部位以利手术。
Objective: To clarify the causes of lower gastrointestinal bleeding and hemostasis. MATERIALS AND METHODS: Selective angiography of 21 patients with hemophagocytic lesion caused by unknown reason was perfused with vasopressin and gelatin sponge by catheterization. Results: The positive rate of angiography diagnosis was 76%. All the 16 patients had hemostasis after treatment. Conclusion: Angiography is the first choice for the diagnosis of gastrointestinal hemorrhage with unknown causes. The hemostatic effect of vasopressin infusion for a short period of one week is significant. However, it is more important for the recurrence and embolization to determine the lesion site to facilitate the operation.
