Video capsule endoscopy vs double-balloon enteroscopy in the diagnosis of small bowel bleeding: A systematic review and meta-analysis

Figure 8 Suggested management approach to overt and occult small-bowel bleeding after upper endoscopy and colonoscopy did not identify vascular bleeding origin. Positive test results should direct specific therapy. When video capsule endoscopy is contraindicated or unavailable, device-assisted endoscopy may serve as the initial test for small-bowel evaluation. VCE: Video capsule endoscopy; DAE: Device-assisted endoscopy; DBE: Double-balloon enteroscopy.
