RESUMO
Objective:To investigate the characteristics and related risk factors for postoperative surgical site infection(SSI) for patients of left-sided colon radical operation , so as to guide clinical intervention measures.Methods:Three hundred and twenty-two patients who underwent left-sided colon radical operation between January 2015 and December 2019 were surveyed retrospectively in the Department of Gastrointestinal and Anal Surgery, Jilin university First Hospital, including 205 male, and 117 female, aged from 18 to 80 years old. The clinical data for each patient were collected and analyzed. The influencing factors and possible risk factors were conducted by single factor analysis and Logistic analysis.Results:Among 332 patients, 79 patients developed SSI, total SSI rate was 24.5%, among which 56 cases of superficial incision infection and 23 cases of organ/lacunar infection. Single factor analysis showed that hypoalbuminema(<35 g/L), BMI≥24 kg/m 2, ASA≥3, operation time≥120 min, hospitalization time≥10 d, diabetes, hospitalization expenses, anastomotic leakage were high risk factors for SSI. Logistic analysis showed the risk factors for SSI infection were diabetes, ASA≥3, operation time≥120 min, hypoalbuminema(<35 g/L). Conclusions:The occurrence of SSI was related to multiple factors. The patients with hypoalbuminema(<35 g/L), BMI≥24 kg/m 2, ASA≥3, operation time≥120 min were high-risk factors for SSI. The implementation of relevant prevention or intervention measures should be intensified.
