A 75 year old man presented with a three day history of melaena without any abdominal pain. He had one episode of haematemesis (about 100 ml blood) in the emergency room. He had no previous history of peptic ulcer disease but had significant heart disease with coronary arterial by pass graft in 1992, poor left ventricular function, paroxysmal atrial fibrillation, and type 2 diabetes. His regular medications included aspirin, warfarin, bisoprolol, bumetamide, amiodarone, lisinopril, and metformin. He was tachycardic with a pulse of 110 beats/min and blood pressure of 110/66 mm Hg. No abdominal tenderness was noted on examination and rectal examination revealed black tarry stool.
Laboratory tests showed a haemoglobin of 93 g/l (135−180) and international normalised ratio of 3.0. He was initially treated with 5 mg of vitamin K intravenously, fresh frozen plasma, and blood transfusion. An urgent upper gastrointestinal endoscopy showed excess altered and clotted blood in the fundus of stomach and duodenum but no source of bleeding was seen. He had no further overt bleed overnight but had six units of blood transfusion guided by the haemoglobin level. A repeat upper gastrointestinal endoscopy the following morning showed fresh clotted blood in the fundus of stomach with a bleeding source seen on the body of the stomach (fig 1).
