TI  - Angiographic evaluation and management of nonvariceal upper
      gastrointestinal bleeding.
AB  - Endoscopy is the primary diagnostic and therapeutic tool used in the
      evaluation and treatment of patients with upper gastrointestinal
      bleeding. When endoscopy is unsuccessful in identifying or
      controlling GI hemorrhage, however, arteriography is useful in both
      the evaluation and treatment of upper GI hemorrhage.
