Abstract    The key to the management of gastrointestinal  hemorrhage is localization, which can be achieved by detail review of the patients’history, physical examination and scrutinizing the blood. Endoscopy is the first choice for gastroduodenal and colorectal bleeding. For small bowel hemorrhage, CT scan, isotope or wireless capsule endoscopy provide nontraumatic examination for the patients. DSA is very important for massive bleeding, which provides visualization as well as control of bleeding by embolization. For the difficult patients, intraoperative endocopic examination enable accurate localization for resection.
