营养风险指数预测腹腔镜胃癌根治术后早期并发症的价值OA

Objective:To explore the value of the nutritional risk index(NRI)in predicting early complications after laparo-scopic radical gastrectomy.Methods:The clinical data of 150 patients who underwent laparoscopic radical gastrectomy between Jan.2019 and Dec.2024 were retrospectively analyzed to summarize the risk factors for early postoperative complications.Early postoperative complications occurred in 34 cases(22.67％),which were classified as the complication group,and the remaining116 patients served as the control group.Univariate and multivariate logistic regression analyses were used to identify the risk factors for early postoperative complications after radical gastrectomy for gastric cancer.The area under the receiver operating characteristic curve was used to evaluate the value of NRI in predicting early postoperative complications after radical gastrectomy for gastric cancer,and the optimal cut-off value was confirmed.Accordingly,patients were divided into the high nutritional risk group and the low nutritional risk group,and the clinical data of the two groups were compared.Results:Univariate analysis revealed statistically significant differences in age,albumin,NRI,to-tal lymphocyte count,number of lymph nodes dissected,and pathological stage between the complication group and the control group(P<0.05).Multivariate logistic regression analysis showed that NRI was a protective factor for early postoperative complications(OR=0.883,95％CI=0.818～0.953,P<0.001).The area under curve of NRI in evaluating postoperative complications after radical gas-trectomy for gastric cancer was 0.776,with an optimal cut-off value of 93.119.It exhibited favorable predictive value for both total gas-trectomy patients(AUC=0.869,cut-off value=94.670)and partial gastrectomy patients(AUC=0.721,cut-off value=90.756).The total incidence of early postoperative complications in the high nutritional risk group was higher than that in the low nutritional risk group(P<0.001).Conclusions:NRI<93.119 can serve as an objective indicator for preoperative nutritional intervention.Patients with preoperative NRI<93.119 should be given preoperative nutritional support in time.
