Correlation Analysis of Preoperative Nutrition Risk and Postoperative Complications in Patients with Colorectal Cancer
Objective To investigate the correlation between preoperative nutrition risk and postopera-tive complications in patients with colorectal cancer.Methods Total 90 patients with colorectal cancer who received surgical treatment in Anyang Cancer Hospital from January 2021 to December 2023 were se-lected and divided into high-risk malnutrition group(NRI≤100)and low-risk malnutrition group(NRI＞100)according to preoperative nutrition risk index(NRI).Postoperative complications were compared be-tween the two groups.The correlation between preoperative NRI and postoperative complications was ana-lyzed.Results Among 90 patients,29 cases were in the high risk malnutrition group and 61 cases were in the low risk malnutrition group.Postoperative complications occurred in 20 patients,including 14 cases in the high risk malnutrition group and 6 cases in the low risk malnutrition group.The incidence of post-operative complications in the high risk malnutrition group(48.28％)was significantly higher than that in the low-risk group(9.84％)(P＜0.05).Spearman correlation analysis showed that preoperative NRI was negatively correlated with postoperative complication rate(r=-0.289,P＜0.05).Logistic regres-sion analysis showed that NRI≤100,smoking history and TNM stage were risk factors for postoperative complications in colorectal cancer patients(P＜0.05).Conclusion There is a certain correlation be-tween preoperative nutrition risk and postoperative complications.Good nutritional status before operation helps to reduce the occurrence of postoperative complications.In clinical work,preoperative nutrition risk assessment should be emphasized,nutrition risk stratification can be carried out according to NRI,and targeted nutritional intervention programs can be formulated to improve patient prognosis.
