There was no statistical association with body mass index greater than 25, diabetes mellitus, age over 65 years or with blood transfusion. Conclusions: The SSI is within the reported ranges, the factors for SSI are duration of surgery 120 minutes and more, preoperative stay 24 hours and more, ASA III and IV, contaminated and dirty wound, blood transfusions, use of drains, admission to the intensive care unit, conventional approach and lack of administration of antibiotics before surgery.
