We assessed the independent contributions of the surgical approach and other variables of the National Nosocomial Infections Surveillance System (NNIS) surgical patient component to the surgical site infection risk after cholecystectomy. Laparoscopic cholecystectomy was associated with a lower overall risk of surgical site infection and a lower risk of incisional infection but not a reduced risk of organ-space infection, compared with open cholecystectomy. The contribution of most of the variables of the NNIS surgical patient component to the risk of surgical site infection depended on the depth of the infection.
