UNLABELLED: Ischemic colitis (IC) is an important clinical problem, and may present after aortic surgical procedures. The aim of this work was to establish risk factors for IC presentation in aortic surgical replacement patients.
MATERIAL AND METHODS: A retrospective study of patients with aortic surgical replacement in a 3-year period was carried out. Patients were divided into two groups: patients without IC and patients with IC, the later group subdivided into patients with gangrenous ischemic colitis and without gangrenous ischemic colitis. Multiple logistic regressions was used to obtain the variables for possible risk factor for IC.
RESULTS: We included 101 patients in the study; ischemic colitis was present in 16.8% of all cases, with 47.1% of gangrenous type. Metabolic acidosis was the most frequent alteration. Diagnosis was made by endoscopy in 94.1%. Mortality in IC group was 18.2% with an increase in the gangrenous group to 62.5%. Identified risk factors were disrupted aneurysm, previous colonic surgery, emergency surgery, and hemodynamic instability.
CONCLUSIONS: Ischemic colitis is most frequent in emergency surgery for disrupted aneurysm in the hemodynamically unstable patient with retroperitoneal hematoma. We must entertain a high suspicion index for IC in all patients with aortic surgical procedures for early detection and adequate treatment.
