Abstract
A 73-year-old lady presented with clinical features of gastric outlet obstruction. It was found to be secondary to a spontaneous haematoma in duodenal wall as a complication of warfarin therapy given for atrial fibrillation. The diagnosis was confirmed by abdominal CT scan and upper G I endoscopy. Warfarin was stopped and blood transfusions given. She recovered completely after three weeks of conservative treatment. Repeat CT scan and upper G I endoscopy done after two months showed complete resolution.
