Video capsule endoscopy: procedure, indications and diagnostic yield.

ABSTRACT

Video capsule endoscopy (VCE) is a new noninvasive imaging technique for the complete small bowel. It provides good to excellent visualisation of the mucosa of the small bowel and has a high diagnostic yield in selected patients with gastrointestinal blood loss of suspected small bowel origin and in patients with Crohn's disease. In comparison with small bowel X-ray and push enteroscopy, diagnostic yield appears to be superior. Although VCE is becoming increasingly popular, good studies on its clinical implications and application are only just emerging. In this paper we review the possibilities and limitations of clinical application of VCE.
