下消化道出血的诊断与介入治疗

目的：探讨介入方法在下消化道出血的诊断和治疗中的价值。方法：对11例经过内及钡剂检查来明确出血原因和部位的消化道出血患者，进行选择性动脉造影，通过显示对比例外溢、病理血管和肿瘤染色来确定出血原因及部位。同时对出血处用胶海棉栓塞或用保留导管灌注血管加压素止血。结果：全组11例，其中10例见对比剂外溢1例同时见肿瘤染色，7例显示病理血管。1例未能明确诊断。3例用明胶海棉栓塞治疗，8例采用保留导管灌汪血管加压素治疗，均达到止血效果。结论：介入治疗下消化道出血，可以快速作出定位诊断，且止血效果好，见效快，并发症少，既安全又可靠。

The diagnosis and interventional treatment for lower digestive tract hemorrhage

Objective:To study the value of angiography and interventional treatment for lower digestive tract hemorrhage.Methods:Eleven patients with digestive tract hemorrhage,whose nature and location were unknown by endoscopy and barium meal examination,were performed selective arteriography.The location and cause of hemorrhage were determined by angiography according to demonstration of contrast medium extravasation,abnormal vasculature and tumour staining.Meanwhile,the bleeding artery was embolized with gelfoam or infused with vasopressin for hemostasis.Results:Among 11 cases,10 cases showed contrast medium extravasation except one.1 case showed tumor staining,and 7 showed abnormal vasculature.3 cases underwent embolization with gelfoam and 8 cases infusion with pitressin.All cases obtained hemostasis.Conclusion:Angiography can rapidly locate and detect the cause of hemorrhage in lower digestive tract,and interventional therapy is a safe and effective hemostatic method with fewer complications in lower digestive tract hemorrhage.
