摘　　要：疑似小肠出血在早期被称为不明原因消化道出血,其被定义为不明原因的显性或隐匿性出血,在包括结肠镜和胃十二指肠镜在内的初步阴性的双向内窥镜检查后持续或复发,约占消化道出血的5%~10%。随着视频胶囊内镜(VCE)、血管造影术和辅助小肠镜(DAE)小肠成像技术的发展,大多数不明原因消化道出血的患者能识别出为小肠来源的出血。因此,美国胃肠病学会(ACG)和美国胃肠内窥镜指南(ASGE)指出,在胃镜和结肠镜检查呈阴性后,适宜用“疑似小肠出血”(SSBB)取代“不明原因的消化道出血”(OGIB)一词。尽管如此,由于小肠生理结构的特殊性,其一度被称为“人体黑匣子”,因此,疑似小肠出血的诊断以及治疗对胃肠科医生来说仍然是一项挑战。因此,该文对疑似小肠出血的诊断方法进行系统综述,为临床提供参考。Suspected small bowel bleeding(SSBB)is called obscure gastrointestinal bleeding(OGIB)in the early stage,and it is defined as obscure overt or occult bleeding,which persists or recurs after the initial negative two-way endoscopic examination,including colonoscopy and gastroscopy,accounting for about 5%~10%of gastrointestinal bleeding.With the development of small bowel imaging techniques,including video capsule endoscopy(VCE),angiography and device-assisted enteroscopy(DAE),most patients with obscure gastrointestinal bleeding can recognize bleeding from the small bowel.Therefore,the American College of Gastroenterology(ACG)and American Gastrointestinal Endoscopy Guidelines(ASGE)point out that after gastroscopy and colonoscopy are negative,it is appropriate to use SSBB instead of OGIB.However,because of the particularity of the physiological structure of the small bowel,it was once called"the human black box",so the diagnosis and treatment of SSBB is still a challenge for gastroenterologists.Therefore,this paper systematically reviews the diagnosis methods of SSBB,in order to provide reference for clinical practice.
