Abstract Objective To explore the nutritional status of patients with gastrointestinal cancer and analyze the impact of the nutritional status of patients on postoperative infections， and to provide evidence for prevention and control of postoperative infection. Methods The relevant data of 271 patients with gastrointestinal cancer who underwent tumor surgery Yongchuan Hospital Affiliated to Chongqing Medical University from January 2016 to March 2019 were collected， the nutritional risk screening tool （NRS 2002） was used to screen the nutritional risk of patients before operation， according to the screening results， they were divided into nutrition risk group （121 cases） and non-nutrition risk group（150 cases），the differences between the two groups in general observation indexes， postoperative infection and admission to ICU were compared， and the correlation between the occurrence of postoperative infection and preoperative nutritional status， age， preoperative hematology indexes， surgical status， tumor status and other factors was analyzed. Results The preoperative nutritional risk of patients with gastrointestinal cancer was 44.6%，the total protein， albumin， hemoglobin and lymphocyte in the nutrition risk group were lower than those in the non-nutrition risk group， and the difference were statistically significant （P<0.05）；the incidence of postoperative infection was 27.3% （33/121） in the nutrition risk group and 14.7% （22/150） in the non-nutrition risk group， the difference between the two groups was statistically significant. Multivariate Logistic regression analysis showed that the risk factors of postoperative infection were associated with NRS 2002 ≥ 3 points， drinking history， and operation duration ≥6h， and the differences were statistically significant （P<0.05）. Conclusion The incidence of preoperative nutritional risk in patients with gastrointestinal cancer is high， the incidence of postoperative infection is high in patients with low NRS 2002 score， active measures should be taken to improve the nutritional status of patients.
