[Immuno-Nutritional Factors Affecting the Incidence of Surgical Site Infection（SSI）after Rectal Cancer Surgery].
BACKGROUND
We analyzed immune nutritional factors that affected the incidence of SSI in rectal cancer surgery.


METHODS
A total of 103 patients who underwent rectal cancer resection were enrolled in this retrospective study. The risk factors (DM, BMI<18.5, ≥25.0, PNI≤40, G/L>2, CONUT≥2, mGPS D) for SSI (Grade≥Ⅱ) were analyzed.


RESULTS
The factors that significantly affected SSI (in 13 cases) was PNI≤40 on univariate analysis. In the analysis adjusted by age and sex, mGPS D and PNI≤40 were significant factors. In the stepwise selection method, PNI≤40 was selected as an independent factor.


CONCLUSIONS
As a risk factor for SSI after rectal cancer surgery, PNI≤40 and mGPS were risk factors.
