Abstract: | Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of an unknown origin that persists or recurs after negative initial upper and lower endoscopies.Several techniques,such as endoscopy,arteriography,scintigraphy and barium radiology are helpful for recognizing the bleeding source;nevertheless,in about 5%-10% of cases the bleeding lesion cannot be determined.The development of videocapsule endoscopy (VCE) has permitted a direct visualization of the small intestine mucosa.We will analyze those techniques in more detail.The diagnostic yield of CE for OGIB varies from 38% to 93%,being in the higher range in those cases with obscure-overt bleeding. |
