title: Short-term intravenous antimicrobial prophylaxis in combination with preoperative oral antibiotics on surgical site infection and methicillin-resistant Staphylococcus aureus infection in elective colon cancer surgery: results of a prospective randomized trial.
abstract: OBJECTIVE
  We performed a prospective randomized study to assess the effectiveness of short-term intravenous antimicrobial prophylaxis in combination with preoperative oral antibiotics on a surgical site and methicillin-resistant Staphylococcus aureus (MRSA) infection in elective colon cancer surgery.
  
  
  METHODS
  The patients were administered preoperative oral antibiotics, kanamycin and erythromycin, after mechanical cleansing, which began within 24 h of elective surgery for colon cancer. The patients were randomly assigned to receive the intravenous administration of cefmetazol or cefotiam on the day of surgery (group 1) or for 3 days (group 2). A total of 275 patients (136 for group 1 and 139 for group 2) were eligible for the study.
  
  
  RESULTS
  The incidence of a surgical site infection was 5.1% in group 1 and 6.5% in group 2 (P = 0.80). The incidence of MRSA infection was 2.2% in group 1 and 2.9% in group 2 (P > 0.99). A multivariate logistic regression analysis showed that the American Society of Anesthesiologists physical status score and the duration of surgery were independent significant factors affecting the surgical site infection and MRSA infection.
  
  
  CONCLUSIONS
  These findings suggest that short-term intravenous antimicrobial prophylaxis in combination with preoperative oral antibiotics may be successfully applied to colon cancer surgery that is generally performed in Japan.
