Role of Early Capsule Endoscopy and Device⁃assisted Enteroscopy in Diagnosis of Overt Small Bowel Bleeding / 胃肠病学

ABSTRACT

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.
