Between January 1991 and December 1998, we performed two successful procedures to repair abdominal aortic aneurysm with primary aortoenteric fistula. We had 197 surgical repair proceduers of aortic aneurysm during the same period. Incidence of primary aortoenteric fistula in abdominal aortic aneurysm was 1% in our institute. We performed primary closure of the fistula and removal of the possibily infected aneurysmal wall followed by anatomical grafting. We utilized omental wrapping for prophylaxis of potential graft infection. We achieved excellent surgical results in both patients by this approach.
