早期胶囊内镜和小肠镜检查在小肠显性出血诊断中的作用

Role of Early Capsule Endoscopy and Device-assisted Enteroscopy in Diagnosis of Overt Small Bowel Bleeding

小肠出血是指经常规胃镜和结肠镜检查无法明确病因的胃肠道出血,其中肉眼可见的出血归为显性出血。胶囊内镜、小肠镜等内镜检查在小肠显性出血的诊断中占据重要地位,如何选择合适的时间进行检查与诊断能力密切相关。本文对早期胶囊内镜和小肠镜检查对小肠显性出血的诊断作用和检查时机作一概述。

Small bowel bleeding is defined as bleeding from the gastrointestinal tract where the cause cannot be clearly identified after routine gastroscopy and colonoscopy,of which bleeding visible to the naked eye is classified as overt bleeding.Endoscopy,such as capsule endoscopy and device-assisted enteroscopy,occupies a dominant position in the diagnosis of overt small bowel bleeding,and how to choose the right time for endoscopy is closely related to the diagnostic yield.This article provided an overview of the timing and diagnostic role of early capsule endoscopy and device-assisted enteroscopy in overt small bowel bleeding.
