Abstract：
:Double-balloon enteroscopy (DBE) is an effective tool for diagnosing and treating obscure gastrointestinal bleeding. The aim is to describe how outcomes differ with patient setting (with DBE diagnosis and intervention, with DBE diagnosis but without intervention, and without DBE diagnosis), and thus demonstrate the value of endoscopic intervention when encountering potential bleeder during DBE. From November 2003 to January 2008, 90 patients with obscure gastrointestinal bleeding presented with DBE at our tertiary referral center. A total of 113 DBE procedures were carried out. Overall diagnostic yield was 75.6% (68/90). Endoscopic intervention was performed in 58 (85.3%) of the 68 patients with potential bleeder. The 90 patients were divided into three settings: with endoscopic diagnosis and intervention (n = 58), with endoscopic diagnosis but without intervention (n = 10), and without endoscopic diagnosis (n = 22). Rebleeding rates for the three groups were 22.4%, 60%, and 22.7%, respectively. For the 35 patients diagnosed with vascular lesions, the rebleeding rates in patients with and without endoscopic intervention, were 38.5% (10/26) and 66.7% (6/9), respectively. One (0.9%) severe adverse event occurred during the 113 procedures, and the patient died. DBE is an effective tool for diagnosing and treating obscure gastrointestinal bleeding. DBE involves relatively safe procedures and has an acceptable complication rate. When potential bleeders are encountered during the procedure, especially for vascular lesions, therapeutic intervention should be attempted, since the intervention-related complication rate is acceptable, and such intervention can reduce the rebleeding rate and enhance the cost-effectiveness of DBE.
