| 2 | Assessment of multi-modality evaluations of obscure gastrointestinal bleeding显示文摘AIM To determine the frequency of bleeding source detection in patients with obscure gastrointestinal bleeding(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 patients 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 patients(52% females; median age 68 years) underwent DBE for OGIB. AVCE and/or MPCTE performed within 1 year prior to DBE(in 441 patients) 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 bleeding site at DBE compared to VCE(OR = 1.3, P = 0.150). There were increased odds of finding a bleeding 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 bleeding may benefit from proceeding directly to antegrade DBE. | Ryan Law Jithinraj E Varayil Louis M Wong Kee Song Jeff Fidler Joel G Fletcher John Barlow Jeffrey Alexander Elizabeth Rajan Stephanie Hansel Brenda Becker Joseph J Larson Felicity T Enders David H Bruining Nayantara Coelho-Prabhu | 2017 | World Journal of Gastroenterology2017，23，4： | 1 |
