The patient is a 70-year-old Caucasian man who had recently undergone uncomplicated coronary artery bypass surgery on 12/26/02 and was being treated with aspirin to prevent thrombosis. He was admitted to this Hospital on January 9, 2003 for symptoms of diaphoresis, dizziness, and bright red rectal bleeding. An upper gastrointestinal endoscopy revealed a 6.0 mm cratered antral ulcer which was not actively bleeding as well as a non-bleeding duodenal ulcer with a visible vessel. This ulcer extended from the bulb to the second portion of the duodenum. The vessel was injected with epinephrine and subsequently coagulated with bipolar electrocautery.
