What is the learning curve associated with double-balloon enteroscopy? Technical details and early experience in 6 U.S. tertiary care centers

Management of Obscure Occult Gastrointestinal Bleeding: A Cost-Minimization Analysis

“…In the case of DBE, incomplete upper DBE examinations warrant performing the retrograde procedure another day; it is not uncommon that the antegrade procedure takes 90 minutes while the retrograde procedure is an additional 70 minutes. 15,21,22 The willingness of endoscopists to provide DBE will likely depend on reimbursement;…”

Role of small-bowel endoscopy in the management of patients with inflammatory bowel disease: an international OMED–ECCO consensus
