Abstract :
Obscure gastrointestinal bleeding (OGB) means the bleeding from gastrointestinal tract that can not be detected by conventional investigations. The amount of bleeding can be only scanty amount of blood loss causing anemia or heavy bleeding like hematochezia. Currentl, the standard investigations include optimal
esophagogastroduodenoscopy and colonoscopy. Currently, there are many new techniques available to help for establishing diagnosis such as capsule and double balloon endoscopy. However, many radiological studies such as angiogram and bleeding scan still have a place to facilitate and treat OGB.
