Nutritional risk screening 2002 in preoperative patients with gastric carcinoma / 中华普通外科杂志

ABSTRACT

Objective To evaluate the preoperative nutritional status of patients with gastric carcinoma by using the European Nutritional Risk Screening 2002(NRS 2002)and its prediction for postoperative nutrition-related complications.Methods We prospectively evaluated the nutritional risk of 314 gastric cancer patients admitted in one center from 2004 to 2007 with NRS 2002 with China's normal body mass index(BMI),in terms of postoperative complications,mortality and hospital stay.Results NRS 2002 scoring system was applicable in 93.1% cases.Preoperatively 125 patients were of score≥3,accounting for 39.8% of this group.The postoperative complication rate(26.2%)was higher than 13.8% in those with normal preoperative nutritional scores(NRS 2002 score＜3)(P＜0.05);The odds ratio to develop a complication was 0.642 in patients with preoperative nutritional risk score(P＜0.05),and 1.596 in patients with clinicopathological stage of gastric cancer(P＜0.01).The correlation between length of hospital stay and nutritional risk was also assessed by Pearson correlation analysis.The Pearson coefficient was 0.177(P=0.002).Conclusion Preoperative nutrition score(NRS 2002)≥3 predicts higher postoperative complications and longer hospital stay.Preoperative nutritional support is necessary in patients with preoperative nutrition score(NRS 2002)≥3.
