Predictive factor of re-bleeding after negative capsule endoscopy for obscure gastrointestinal bleeding: over 1-year follow-up study.
Capsule endoscopy (CE) is now widely accepted as a first-line diagnostic modality for obscure gastrointestinal bleeding (OGIB), with a high diagnostic yield compared to other modalities. However, even after negative CE examination, re-bleeding is often known to occur. The aim of the present study was to identify predictive factors of re-bleeding after negative CE, and to clarify the clinical utility of double-balloon enteroscopy (DBE) after negative CE for OGIB. ⋯ In patients of advanced age, more extensive follow up is needed, even if the CE result is negative. In addition, DBE subsequent to negative CE may be useful to detect lesions that were overlooked on CE.
