    PurposeSurgical site infections (SSIs) are the most common infections in colorectal surgery. Although some studies suggest that rectal surgery differs from colon surgery for SSI incidence and risk factors, the National Nosocomial Infection Surveillance system categorizes all colorectal surgeries into only one group. The aim of this study was to determine incidence, characteristics, and risk factors of SSIs according to the subclassification of colorectal surgery into right colon surgery (RCS), left colon surgery (LCS), and rectum surgery (RS).MethodsFrom November 2005 to July 2009, all patients requiring colorectal resectioning were enrolled into our program. The outcome of interest was an SSI diagnosis. Univariate and multivariate analyses were performed to determine SSI predictors in each group.ResultsTwo hundred seventy-seven consecutive colorectal resections were analyzed. SSI rates were 8% in RCS, 18.4% in LCS, and 17.6% in RS. LCS and RS showed significantly higher SSI incidences (p = 0.022) and greater rates of organ/space infections compared to RCS (p = 0.029). Predictors of SSI were steroid use among RCS, age greater than 70 years, multiple comorbidities, steroid use, non-neoplastic colonic disease, urgent operation, ostomy creation, postoperative intensive care among LCS, preoperative chemoradiation, heart disease, and prolonged operation among RS patients. On multivariate analysis, the coupled LCS and RS groups showed an increased risk for SSI compared to RCS (OR, 2.57).ConclusionsSSI incidences, characteristics, and risk factors seem to be different among RCS, LCS, and RS. A tailored SSI surveillance program should be applied for each of the three groups, leading to a more competent SSI recognition and reduction of SSI incidence and related costs.
