ABSTRACT
Background: Surgical site infection (SSI) is one of the most important and costly complications of surgical operations. The present study hypothesized that vitamin D deficiency is associated with an increased risk of SSI, and this current study investigated this hypothesis. Patients and Methods: A prospective cohort study was performed with adult patients undergoing open right hemicolectomy operation with stapled anastomosis between February 2018 and March 2021 in the surgery ward of Imam Khomeini hospital. A logistic regression test examined and analyzed the connection between serum 25-OH vitamin D levels and post-operative wound infections. Results: This study comprised 315 participants who met the inclusion criteria. Pre-operative serum vitamin D levels were <30 ng/mL in 107 participants (34%) and ≥30 ng/mL in 208 participants (66%). The mean serum vitamin D level was 35.66 ± 13.26 ng/mL among the study population. Increased vitamin D deficiency was linked with elevated odds of surgical wound infection incidence among the patients after surgery (odds ratio [OR], 5.49; 95% confidence interval [CI], 2.06-14.6; p = 0.001). Conclusions: Pre-operative vitamin D level strongly affects post-operative SSI in patients with colon cancer. This study highlighted the importance of conducting further research to determine the possible advantages of vitamin D in preventing incision infection after surgery.
