胶囊内镜与其他小肠检查技术的比较

Comparison of capsule endoscopy with other imaging modalities in small bowel

由于小肠解剖结构特殊,传统技术对大部分小肠的检查受到很大限制.胶囊内镜的问世填补了小肠无创性、可视化检查的空白.胶囊内镜能够直接观察全小肠黏膜,且敏感性高、安全无创,逐渐成为诊断小肠疾病的重要手段,广泛用于不明原因消化系出血、小肠克罗恩病、家族性腺瘤性息肉病等小肠疾病的诊断和监测.但是,胶囊内镜也表现出特异性不足的缺点,发现的部分异常并不具有临床意义,而且其使用前需排除小肠梗阻等情况.现就近年来胶囊内镜的应用与其他小肠检查技术进行阐述.

Until only a few years ago, most of the small bowel was beyond the range of conventional examinations Because of its special anatomical position. The advent of capsule endoscopy （CE） represents a significant breakthrough for noninvasive and visual diagnosis of diseases in the small bowel. Since CE permits direct acquisition of images from the mucosa with high sensitivity and safety, it has become an important tool for diagnosis and surveillance of obscure gastrointestinal bleeding, Crohn＇s disease, familial adenomatous polyposis and other small bowel diseases. However, CE also has some weakness such as low specificity and risk of retention. In this review, we will compare CE with other imaging modalities in small bowel.
