title: Primary aorto-enteric fistula: a practicable curable condition? Pathogenetic and clinical aspects.
abstract: Primary aorto-enteric fistulas is now being a rare occurrence because of an aggressive approach in terms of surgery of abdominal aortic aneurysms. Three cases is presented in an attempt to elucidate the ethiology, pathogenesis and diagnostic possibilities when dealing with primary aorto-enteric fistulas. The clinical presentation of the patients with primary aorto-enteric fistulas is inconstant, but a hightened index of suspicion should be present when a patient presents with gastrointestinal bleeding of obscure origin, abdominal or back pain and an abdominal mass. Endoscopy and diagnostic imaging may detect a fistula, but a high rate of false negative investigations are produced. The result of diagnostic workup is often laparotomy, which is the safest diagnostic method and may save the patients life.
