Background: Sarcopenia is a syndrome that can be associated with unfavorable outcomes after colorectal cancer surgical procedures. The present study evaluates the relationship between sarcopenia and surgical site infections (SSIs) that can occur after colorectal cancer operations and that are a significant cause of morbidity. Methods: The research was designed as a retrospective study in which data were collected on patients who underwent colorectal cancer surgical procedures between January 2013 and July 2019. A diagnosis of sarcopenia was established based on the skeletal muscle index (SMI), calculated from pre-operative computed tomography scans. The SSI scores of patients with sarcopenia (sarcopenic group, SG) and those without sarcopenia (non-sarcopenic group, NSG) were compared, and a logistic regression analysis was performed to determine the risk factors for SSI. Results: A total of 209 patients with a mean age of 61.2 years were included in the study. Post-operative complications (Clavien-Dindo ≥1) developed in 97 (46.4%) patients, SSIs developed in 46 (22%) patients, and sarcopenia developed in 97 (46.4%) patients. The mean age was 64.8 years in the SG group and 58.1 years in the NSG group (p = 0.016). No significant relationship was found between the development of SSI and sarcopenia (20 (20.6%) patients in the SG vs. 26 (23.2%) patients in the NSG, p = 0.65). Those in whom superficial SSIs developed in the early period formed the largest group (20 patients). The most commonly detected micro-organism was Escherichia coli with a rate of 55%. In a multi-variable logistic regression analysis, only the non-laparoscopic approach was identified as a risk factor (odds ratio 3.83; 95% confidence interval 1.26-11.58; p = 0.017). Conclusions: The present study reports no relationship between sarcopenia and SSI after colorectal cancer operations. The authors consider that studies that endeavor to reduce the incidence of SSI, as a significant cause of morbidity after colorectal surgical procedures, should be supported.
