AIM: To determine the frequency of @entity548 source detection in @entity1 with obscure @entity360 (OGIB) who underwent double balloon enteroscopy (DBE) after pre-procedure imaging [multiphase computed tomography enterography (MPCTE), video capsule endoscopy (VCE), or both] and assess the impact of imaging on DBE diagnostic yield. METHODS: Retrospective cohort study using a prospectively maintained database of all adult @entity1 presenting with OGIB who underwent DBE from September 1(st), 2002 to June 30(th), 2013 at a single tertiary center. RESULTS: Four hundred and ninety five @entity1 (52% females; median age 68 years) underwent DBE for OGIB. AVCE and/or MPCTE performed within 1 year prior to DBE (in 441 @entity1 ) increased the diagnostic yield of DBE (67.1% with preceding imaging vs 59.5% without). Using DBE as the gold standard, VCE and MPCTE had a diagnostic yield of 72.7% and 32.5% respectively. There were no increased odds of finding a @entity548 site at DBE compared to VCE (OR = 1.3, P = 0.150). There were increased odds of finding a @entity548 site at DBE compared to MPCTE (OR = 5.9, P < 0.001). In inpatients with overt OGIB, diagnostic yield of DBE was not affected by preceding imaging. CONCLUSION: DBE is a safe and well-tolerated procedure for the diagnosis and treatment of OGIB, with a diagnostic yield that may be increased after obtaining a preceding VCE or MPCTE. However, inpatients with active ongoing @entity548 may benefit from proceeding directly to antegrade DBE.
