Obscure gastrointestinal bleeding (OGIB) refers to bleeding of uncertain origin that persists or recurs after negative workup using any of the radiologic evaluation modalities. It can be divided into two types based on whether clinically evident bleeding is present, namely, obscure overt and obscure occult bleeding. As the visualization of the bowel mucosa is challenging, capsule endoscopy (CE) is the ideal go-to procedure as the process is wireless, ingestible, small, disposable, and, most importantly, non-invasive. This review article has compiled various studies to shed light on the guidelines for using CE, its structure and procedure, patient preferences, diagnostic yield, cost-effectiveness, and the future. The goal of this review is to show the influence of CE on OGIB on the aspects mentioned earlier.
不明原因胃肠道出血（OGIB）是指在使用任何放射学评估方法进行检查结果为阴性后仍持续或复发的来源不明的出血。根据临床上是否存在明显出血，可分为两种类型，即显性不明原因出血和隐匿性不明原因出血。由于肠道黏膜的可视化具有挑战性，胶囊内镜检查（CE）是理想的首选检查方法，因为该检查过程无线、可吞咽、体积小、一次性使用，而且最重要的是无创。这篇综述文章汇集了各种研究，以阐明使用CE的指南、其结构和操作程序、患者偏好、诊断率、成本效益以及未来发展。这篇综述的目的是展示CE在上述方面对OGIB的影响。
