The optimal time of double balloon enteroscopy for patients with obscure gastrointestinal bleeding: a case-control study / 中华消化内镜杂志

ABSTRACT

Objective To investigate the optimal time for double balloon enteroscopy (DBE) in patients with obscure gastrointestinal bleeding (OGIB).Methods Data of 78 patients with OGIB who underwent DBE from January 2009 to November 2013 were retrospectively analyzed.They were classified into two groupsemergency DBE and non-emergency DBE.The demographic and clinical features and outcomes of DBE,the time of examination and complications were compared.Results The overall diagnostic yield of DBE was 48 lesions (61.54 ％).The overall diagnostic yield of emergency DBE group was 77.14％,which was significantly higher than that in non-emergency DBE group (48.83％) (P =0.019).The time of examination in emergency group was shorter than that of non-emergency group with significant difference (P =0.031).Conclusion Emergency DBE takes less time and yields a higher rate of detection.Patients withOGIB should receive DBE as soon as possible.
