title: [Obscure gastrointestinal bleeding].
abstract: Obscure gastrointestinal bleeding represents 5% of all cases of bleeding into the gastrointestinal tract (GIT). The cause of this type of bleeding cannot be found by gastroscopy or colonoscopy - the most common cause being bleeding from the source in the small intestine. In other cases it is bleeding from other parts of the digestive tube which has already stopped or was not noticed during admission endoscopy. Imaging methods (X-ray, CT, MRI, scintigraphy) and endoscopic methods (flexible or capsule enteroscopy) are used in the diagnosis and treatment. If, despite having used these methods, the source of bleeding is not found and the bleeding continues, or if the source is known but the bleeding cannot be stopped by radiologic or endoscopic intervention, surgical intervention is usually indicated. The article provides an overview of current diagnostic and treatment options, including instructions on how to proceed in these diagnostically difficult situations.
