Small bowel angioectasias (SBA) are vascular malformations consisting of thin-walled, dilated capillaries located in the gastrointestinal mucosa. They are responsible for 10% of all causes of gastrointestinal bleeding and 60% of small bowel bleeding pathologies. The diagnosis and management of SBA depend upon bleeding acuity, patient stability and patient characteristics. Small bowel capsule endoscopy is a relatively noninvasive diagnostic approach ideal for non-obstructed and hemodynamically stable patients. It is superior to computed tomography scans in visualizing mucosal lesions, such as angioectasias, as it provides mucosal views. Management of these lesions will depend on the patient's clinical condition and associated comorbidities, and very often consists of medical and/or endoscopic treatment delivered through small bowel enteroscopy.
小肠血管扩张症（SBA）是一种血管畸形，由位于胃肠道黏膜的薄壁、扩张的毛细血管组成。它们占胃肠道出血所有病因的10%，以及小肠出血性病变的60%。SBA的诊断和管理取决于出血的严重程度、患者的稳定性和患者特征。小肠胶囊内镜检查是一种相对无创的诊断方法，适用于无梗阻且血流动力学稳定的患者。在可视化黏膜病变（如血管扩张症）方面，它优于计算机断层扫描，因为它能提供黏膜视图。这些病变的管理将取决于患者的临床状况和相关合并症，并且通常包括通过小肠镜检查进行的药物和/或内镜治疗。
