colonoscopy is used routinely, the incidence of endo-scopically diagnosed CI appears to increase dramatically to 60%.1,3-7 When CI is present the mortality rate exceeds 60%, whereas transmural necrosis, as a result of CI, is associated with a higher mortality rate approach-ing 90%.8,9 Late recognition of CI usually results in a fatal outcome. Based on these data, several investigators have focused on the need for timely identification of patients with CI to decrease subsequent mortality rate with early and appropriate intervention. Patients who survive ruptured abdominal aorticaneurysm (rAAA) are susceptible to a variety ofserious postoperative complications.1,2 Among these one of the most significant is colonic ischemia Purpose To evaluate the reliability of selective surveil-lance colonoscopy based on 6 specific perioperative risk factors in the early diagnosis of colonic ischemia (CI
