title: [Primary aortoduodenal fistula: apropos of 2 cases].
abstract: Aortoenteric fistulas are rare. Located at various level of the gastrointestinal tract - from the esophagus to the rectum - the most frequent are aortoduodenal, secondary to abdominal aortic aneurysms. Two new cases, successfully treated, are reported. The characteristic clinical symptoms are abdominal aortic aneurysm, pain and gastrointestinal bleeding; recurrent bleeding is usual; endoscopy is the accuratest method of early diagnosis. Aggressive surgical approach is mandatory: in addition to a prosthesis in uninfected area, even in extra-anatomical position, epiplooplasty between the graft and the gastrointestinal tract is recommended.
