The role of preoperative oral immunonutrition in major vascular surgery.

The mean purpose of this study was to determine the prevalence of post-operative infection complications after major vascular surgery in group of patients with preoperative oral immunonutrition.

This group was compared to a control group.

Secondary purpose was to evaluate the effect of preoperative oral immunonutrition on postoperative mortality (30 days), the medium length of stay in the hospital and the cost of treatment in the two groups
