Since it was introduced 17 years ago, capsule endoscopy has become an important diagnostic tool for the small bowel. Three generations of the original small bowel capsule have been developed since (PillCam SB3, Medtronic, USA), and four competitors were introduced for the small bowel. A non-video patency capsule (Agile patency capsule, Medtronic, USA) was also developed, in order to confirm patency and thus avoid retention in the GI tract. Moreover, capsules viewing other organs of the body (esophagus, colon) as well as three different magnetic guided capsules that visualize the stomach as good as optical endoscopy (OE) have been developed. Over 2,000 articles looking at the efficacy of the small bowel capsule in different clinical situations were published since then. Studies are comparing capsule endoscopy versus other modalities in various indications, looking at preparations aiming to improve the diagnostic yield and at technical aspects. The present paper, describes the available capsules in the market and my biased future expectations.
自17年前被引入以来，胶囊内镜已成为小肠的重要诊断工具。此后，原始小肠胶囊已发展到第三代（美国美敦力公司的PillCam SB3），并且有四款用于小肠的竞品被推出。还研发了一种非视频通畅性胶囊（美国美敦力公司的Agile通畅性胶囊），以确认肠道通畅，从而避免在胃肠道内滞留。此外，还研发了用于观察身体其他器官（食管、结肠）的胶囊，以及三种不同的磁控胶囊，其对胃的可视化效果与光学内镜（OE）一样好。从那时起，发表了2000多篇关于小肠胶囊在不同临床情况下疗效的文章。各项研究正在不同适应症中比较胶囊内镜与其他检查方式，探讨旨在提高诊断率的准备工作以及技术方面。本文介绍了市场上现有的胶囊以及我带有偏向性的未来期望。
