摘要
目的分析总结小肠出血的病因及临床特点。方法回顾性分析2000年1月～2007年6月北北京协和医院收治77例小肠出血的病因与临床特点。结果89．6％（69／77）和81．1％（63／77）患者出血前无明显症状和腹部阳性体征。平均Hb（55±43.78）g／L．确诊时间（3．22±0．59）年。慢性显性出血49例，慢性隐性出血7例，急性或反复急性大出血21例，确诊率58．4％（45／77）。血管畸形占33．3％（15／45），小肠炎症28．9％（13／45），小肠肿瘤13．3％（6／45），小肠憩室6.7％（3／45），其他肠道吻合口出血2例，肠伤寒、肠紫癜等少见病各1例。结论缸管畸形、小肠炎症、小肠肿瘤是小肠出血的三大常见病因；小肠炎症发病较前增加、小肠出血临床症状与体症少且无特异性，是小肠出血病因学诊断的难点。
Objective To analyze the etiology and clinical feature of small bowel hemorrhage. Methods Seventyseven patients with obscure gastrointestinal bleeding were evaluated from Jan 2000 to Jun 2007 in Peking Union Medical College（PUMC） hospital. The etiology and clinical feature were analyzed retrospectively. Results For all patients, 89.6% （69/77）and 81. 1% （63/77） without obviously symptoms and abdominal physical signs before their bleeding were found. The mean Hb was（55 ~43.78 ）g/L and the diagnostic time was （3.22 ＋ 0. 59 ） years. Obscure bleeding was 49 cases. Overt bleeding was 7 and acute massive bleeding was 21. The accuracy diagnostic was 58.4% （45/77）. Angiodysplasia were found in 15 cases（33.3% ）, inflammation bowel disease in 13（28.9% ）, small bowel tumor in 6 （13.3%）, diverticula in 3 （6.7%）. A few of etiology was included as anastomosis, ileotyphus and purpura, et al. Conclusion Angiodysplasia, inflammation disease and tumor are the main common causes of small bowel hemorrhage. The incidence of enteritis is increasing. It is difficult to identify the etiology of small bowel bleeding in the patients lack of the specific clinical symptom and physical sign before the bleeding.
