title: Double-balloon enteroscopy for obscure gastrointestinal bleeding: a single center experience in China.
abstract: OBJECTIVE
  To evaluate the diagnostic value of double-balloon enteroscopy (DBE) for obscure gastrointestinal bleeding (OGIB).
  
  
  METHODS
  The data about 75 OGIB patients who underwent DBE in January 2007-June 2009 in our hospital were retrospectively analyzed.
  
  
  RESULTS
  DBE was successfully performed in all 75 patients without complication. Of the 75 patients, 44 (58.7%) had positive DBE findings, 22 had negative DBE findings but had potential bleeding at surgery and capsule endoscopy, etc. These 66 patients were finally diagnosed as OGIB which was most commonly caused by small bowel tumor (28.0%), angiodysplasia (18.7%) and Crohn's disease (10.7%). Lesions occurred more frequently in proximal small bowel than in distal small bowel (49.3% vs 33.3%, P = 0.047).
  
  
  CONCLUSIONS
  DBE is a safe, effective and accurate procedure for the diagnosis of OGIB.
