Video Capsule Endoscopy: Technology, Reading, and Troubleshooting

Abstract

Video capsule endoscopy (VCE) has completed the endoscopic visualization of the entire luminal gastrointestinal tract. VCE can be performed in inpatients and outpatients, requires appropriate bowel preparation before the study, and can be administered via oral swallowing or endoscopic device placement into the small bowel based on outlined patient-dependent factors. Current commercially available VCE systems were reviewed and compared for individual features and attributes. This article focuses on preparation for VCE, currently available VCE technology, how to read a VCE study, and risks and contraindications to VCE.
