- Abstract
The aim of the present study was to draw an outline of the clinical epidemiology of bleeding gastrointestinal angiodysplasias. The study includes a report of a case and of our series of patients with bleeding gastrointestinal angiodysplasias admitted, between 1993 and 2003, to a ward of Internal Medicine where digestive endoscopy is also performed. A review of the literature is also provided. An 80-year-old cirrhotic woman with aortic stenosis, was referred to our Department because of anemia due to melena. In spite of 13 hospitalizations during which numerous diagnostic procedures including endoscopy, X-ray studies, arteriography, labeled red blood cells scanning and laparotomy with intraoperative ileoscopy, the site and nature of the bleeding lesion remained unidentified. Her red blood cell requirement progressively increased from 6 U in 1993 to 24 U in 1994 to 40 U as of September 1995. Enteroscopy disclosed duodeno-jejunal angiodysplasia. The patient subsequently received 35 additional red blood cell units during 7 new admissions. Between 1993 and 2003, 24 patients were identified. They were mainly women and their average age was 77 years. Angiodysplasias were localized in the large bowel in 92% of cases. Comorbidities included: heart disease (79%), chronic liver disease (29%) and chronic renal failure (21%). One fourth of patients were under anticoagulant drugs or had a hemostatic blood disorder. All patients received blood transfusions and endoscopic treatment was performed in approximately half of the cases. The most relevant updates are related to the pathogenic relationship between aortic stenosis, von Willebrand's disease and bleeding gastrointestinal angiodysplasias, the hemostatic alterations associated with liver cirrhosis or with chronic renal failure and the diagnosis and treatment of bleeding gastrointestinal angiodysplasias. A better understanding of the clinical epidemiology of bleeding gastrointestinal angiodysplasias may facilitate their diagnosis and contribute to an effective clinical management.
