上消化道胶囊内镜现状及研究进展

Current status and future developments of upper gastrointestinal tract capsule endoscopy

胶囊内镜是一种安全、无创、人群接受度高的消化道疾病诊断系统,目前已广泛用于小肠疾病的诊断.由于食管通过速度快,胃腔空间大,导致胶囊内镜在上消化道中的应用面临巨大挑战.目前随着磁导航技术、系线胶囊技术等工程技术的发展,胶囊内镜逐步拓展了在上消化道疾病诊断中的应用.有多款上消化道胶囊内镜已应用于临床,同时有更多的胶囊内镜新兴技术正处于研发阶段,为改善胶囊内镜在上消化道疾病诊断中的作用提供了新的希望,本文就用于上消化道的胶囊内镜现状及研究进展做一综述.

Capsule endoscopy has been widely used for the diagnosis of small bowel diseases due to its safety,noninvasiveness,and acceptability.Despite the potential benefits of capsule endoscopy,there are obvious challenges to capsule endoscopy application in the upper gastrointestinal tract,due to the fast transit speed in the esophagus and large space of the gastric cavity.With the development of innovative technologies,such as magnetic navigation and tethered capsule endoscopy,the indications for capsule endoscopy have recently been expanded.Various capsule endoscopes have been applied to clinical practice,and several state-of-the-art research-oriented designs and devices provide hope for further use in the diagnosis of upper gastrointestinal diseases.In this review,we will summarize the current status and future developments of upper gastrointestinal tract capsule endoscopy.
