AIM: To identify patients' characteristics associated with double balloon endoscopy (DBE) outcomes in investigation of obscure gastrointestinal bleeding (OGIB). METHODS: Retrospective study performed at an academic tertiary referral center. Evaluated endpoints were clinical factors associated with no diagnostic yield or non-therapeutic intervention of DBE performed for OGIB evaluation. RESULTS: We included fifty-five DBE between August 2010 and April 2012. The mean age of the sample was 67 with 32 males (58.2%). Twenty-four DBE had no diagnostic yield and 30 DBE did not require therapy. Non-diagnostic yield was associated with performing two or more DBE studies in one day [odds ratio (OR): 13.72, P = 0.008], absence of blood transfusions within a year of the DBE (OR: 7.16, P = 0.03) and absence of ulcers or arteriovenous malformations (AVMs) on prior esophagogastroduodenoscopy (EGD) or colonoscopy (OR: 19.30, P = 0.033). Non-therapeutic DBE was associated with performing two or more DBE per day (OR: 18.579, P = 0.007), gastrointestinal bleeding episode within a week of the DBE (OR: 11.48, P = 0.003), fewer blood transfusion requirements prior to DBE (OR: 4.55, P = 0.036) and absence of ulcers or AVMs on prior EGD or colonoscopy (OR: 8.47, P = 0.027). CONCLUSION: Predictors of DBE yield and therapeutic intervention on DBE include blood transfusion requirements, previous endoscopic findings and possibly endoscopist fatigue.
