摘要
目的：探讨和分析小肠出血诊断问题。方法：对52例经动脉造影、核素扫描、小肠钡灌等1项或多项检查及手术证实的小肠出血进行分析、结果：良性病变（82．7％）多于恶性病变（17．3％）。良性病变中以平滑肌瘤及血管病变为主，以便血而无呕血及特异性消化道症状为其临床特点。小肠钡灌可提高诊断率，但其应用受急诊检查条件差，插管困难等影响，本组仅作2例，ECT可以做为血管造影的预先检查项目。结论：本组血管造影21例，17例阳性，占81％，对小肠平滑肌瘤和血管病变确诊率高。对剖腹探查及术中肠镜仍未能发现病变者应慎重考虑是否切除肠段．
Objectives: Analysis and discussion on diagnosis of small intestinal hemorrhage.Methods: To assess the role of various diagnostic methods in 52 cases of small intestinal bleeding confirmed by surgery, digtal subtraction angiography(DSA), emission computed tomagraphy(ECT) and enteroclysis. Results: Intestinal bleeding due to beign diseases (43 cases, 82.7％),malignancy(9 cases, 17.3％),leioinyoma and angiodysplasia (27/43,62.8％) were most common. The characteristic feature of the small intestinal bleeding was hematochezia without hematemesis and gastrointestinal symptoms. Enteroclysis is helpful to the diagnosis, but limited by difficult tube insertion during acute massive bleeding and was done in 2 cases only in our series. ECT is non-invasive and can be used as a screening test. Conclusions: DSA was dones in 21 cases and the positive rate was 81％(21/17).The accuracy of DSA was high especially in small bowel leiomyoma and angiodysplasia.Intestinal segmentectomy should be considered if the bleeding focus could not be found during operation and during intraoperative enteroscopy.
