title: Risk factors for surgical site infection after gastric surgery: a multicentre case-control study.
abstract: BACKGROUND
  Surgical site infection (SSI) is a potentially morbid and costly complication of surgery. We conducted a multicentre case-control study to determine the risk factors for SSI in patients undergoing gastric surgery and to establish strategies to reduce the risk of SSI.
  
  
  METHODS
  Between January 2007 and December 2008, 121 patients who developed an SSI after gastric surgery were matched with controls who had undergone surgery on the dates closest to those of the cases, at 13 centres in Korea.
  
  
  RESULTS
  The results of multivariate analyses showed that the independent risk factors for SSI after gastric surgery were older age (p = 0.016), higher body mass index (BMI) (p = 0.033), male gender (p = 0.047), and longer duration of prophylactic antibiotic use (p < 0.001).
  
  
  CONCLUSIONS
  Older age, higher BMI, male gender, and longer duration of prophylactic antibiotic use were independently associated with significant increases in the risk of SSI. Additional prospective randomized studies are required to confirm these results.
