Obscure gastrointestinal bleeding (OGIB) is bleeding in the digestive tract which persist or recur and with unclear aetiology. OGIB is one of the important problems in the gastrointestinal field due to difficulty in diagnosing the aetiology and determining the source of digestive tract bleeding in patients. In diagnosing the cause of OGIB, clinical approach through history taking and physical examination still have important roles. Most of the sources of bleeding in OGIB is from the small intestine, which cannot be reached by esophagogastroduodenoscopy (EGD) or colonoscopy. Therefore, role of diagnostic tool which is able to perform total enteroscopy becomes important in diagnosing the cause of OGIB. Double balloon enteroscopy (DBE) technique is a safe endoscopy procedure which may use oral or even rectal approach. In finding the cause of OGIB, where most of the lesions is found in the proximal region of the small intestine, oral approach is more beneficial. When bleeding is not found after conventional endoscopy is performed, it needs to be suspected that the source might come from the small intestine. Currently, the two main modalities which can be used in the evaluation are video capsule endoscopy (VCE) and DBE. However, based on cost effectiveness DBE without prior VCE has benefit because it can also administer therapy in the abnormalities being found.
