UNASSIGNED: Background and study aims: In overt obscure @entity360 (OV), double balloon endoscopy (DBE) is recommended as one of the most important investigations as it can provide both diagnosis and treatment. However, there is no set standard on the timing of DBE in OV. The aim of this study was to compare the diagnostic and therapeutic yields between urgent and non-urgent DBE in @entity1 with OV. @entity1 and methods: Between January 2006 and February 2013, 120 @entity1 with OV who underwent DBE were retrospectively reviewed. An urgent DBE was defined as DBE performed within 72h from the last visible @entity360 (n=74) whereas a non-urgent DBE was defined as DBE performed after 72h (n=46). Diagnostic yields, therapeutic impact and clinical outcomes were evaluated. Results: Diagnostic yield in urgent DBE was significantly higher than that in non-urgent DBE (70% versus 30%; P<0.05). Urgent DBE offered significantly more therapies including endoscopic, angiographic embolization, and surgery than non-urgent DBE (54% versus 15%; P<0.001). Endoscopic therapy was performed in 43% of urgent-DBE @entity1 whereas only 13% of @entity1 in the other group received endoscopic therapy (P<0.01). In @entity1 with identified @entity548 sources, the rebleeding rate was lower in @entity1 who underwent urgent DBE than in those who underwent non-urgent DBE (10% versus 29%, NS). Conclusions: Regarding diagnostic and therapeutic impacts in OV, our retrospective study showed that urgent DBE is better than non-urgent DBE. The recurrent @entity548 rate in @entity1 undergoing urgent DBE tended to be lower.
