In a very few years, the video capsule for small bowel enteroscopy has gained widespread clinical acceptance. It is readily ingested, disposable, and allows for a complete, low-invasive endoscopic examination of the entire mucosa of the small bowel. It is a patient-friendly method and a first-line procedure in the difficult evaluation of obscure gastrointestinal bleeding. It has the highest proven figure of diagnostic sensitivity for detecting lesions of the mucosa, irrespective of aetiology. The limitations of capsule endoscopy include difficulty in localising mucosal lesions anatomically and its restricted use in patients with dysphagia, strictures or motor dysfunction. Strictures, transmural and extra-mural lesions in patients with small bowel Crohn's disease are evaluated by MRI- enterography and CT-enterography.
在短短几年内，用于小肠肠镜检查的视频胶囊已获得广泛的临床认可。它易于吞咽、一次性使用，并且能够对小肠的整个黏膜进行完整的、低侵入性的内镜检查。这是一种对患者友好的方法，也是在评估不明原因的胃肠道出血时的一线检查手段。在检测黏膜病变方面，无论病因如何，它都具有经证实的最高诊断敏感性。胶囊内镜的局限性包括在解剖学上定位黏膜病变存在困难，以及在吞咽困难、狭窄或运动功能障碍患者中的应用受限。小肠克罗恩病患者的狭窄、透壁和壁外病变通过磁共振肠造影和计算机断层扫描肠造影进行评估。
