Prediction Value of Postoperative Abdominal Infection by Preoperative Nutritional Risk Index in Patients with Colorectal Cancer
Objective To explore the predictive value of preoperative nutritional risk index(NRI)for postoperative abdominal infections in colorectal cancer patients.Methods A prospective study was conducted on 125 colorectal cancer patients who underwent laparoscopic radical surgery and were admitted to the Third Affiliated Hospital of Luohe Medical College from April 2019 to April 2022.Relevant examinations were conducted and preoperative NRI was calculated.After 14 days of follow-up,patients were divided into two groups based on the incidence of postoperative abdominal infections during the follow-up period:the occurrence group and the non-occurrence group.Logistic regression analysis was used to examine the relationship between preoperative NRI and postoperative abdominal infection in patients with colorectal cancer,and to explore its predictive value for postoperative abdominal infection.Results Among the 125 patients,31(24.80％)experienced postoperative abdominal infection,while 94(75.20％)did not experience postoperative abdominal infection.There was statistically difference in preoperative NRI,surgical time and tumor TNM staging between the two groups of patients(P＜0.05),and there was no statistically difference in other general data between groups(P＞0.05).The results of logistic regression analysis showed that tumor TNM stage Ⅲ was a risk factor for postoperative abdominal infection in colorectal cancer patients(OR＞1,P＜0.05),and high preoperative NRI was the protective factor for postoperative abdominal infection in colorectal cancer patients(OR＜1,P＜0.05).The receiver operating characteristic curve was drawed,and the results showed that AUC of NRI ≥0.7,which has certain predictive value for postoperative abdominal infection in colorectal cancer patients.When the optimal threshold value of 90.770 was taken,the best predictive value could be obtained.Conclusion Low preoperative NRI can increase the risk of postoperative abdominal infection in patients with colorectal cancer.Early detection of preoperative NRI can be used to predict the risk of postoperative abdominal infection in patients.
