Obscure Gastrointestinal Bleeding: The Role of the Tagged Red Blood Cell Scan, Enteroscopy, and Capsule Endoscopy
published online 23 September 2005.
A 65-year-old African American man was referred for obscure gastrointestinal bleeding. He initially had presented 3 months previously with anemia and melena. Both upper-gastrointestinal endoscopy and colonoscopy on 2 occasions had not shown a bleeding source. A tagged technetium-99m red blood cell bleeding scan was negative. He had no weight loss or abdominal pain. He had received a total of 25 units of blood. Physical examination was unremarkable.
