Nutritional risk screening in preoperative patients with colorectal carcinoma and its influence on postoperative outcomes / 中国医师进修杂志

ABSTRACT

Objective To evaluate the preoperative nutritional status of patients with colorectal carcinoma by using the nutritional risk screening 2002 (NRS2002) score and its prediction for postoperative outcomes.Methods Retrospectively evaluated the nutritional risk of 259 colorectal cancer patients with NRS2002 score in terms of different sexes,ages,tumor location,pathology and differentiation,Dukes stages.The relationship between different NRS2002 score and postoperative complications and hospital stay were also observed.Results NRS2002 score was applicable in 243 cases,≥ 3 scores of 80 cases,＜ 3 scores of 163 cases.Gender,histological differentiation and before surgery NRS2002 score unrelated (P ＞ 0.05).Ages,tumor location,and Dukes stages related NRS2002 score (P ＜ 0.01).No case of perioperative death,hospital stay 10-101 (21.6 ± 9.7) d.The incidence of complications in ≥ 3 scores patients was significantly higher than that in ＜ 3 scores patients [30.0％ (24/80) vs.17.2 ％ (28/163),P ＜ 0.05],hospital stay in ≥ 3 scores patients was significantly shorter than that in ＜ 3 scores patients[(20.5 ± 8.2) d vs.(23.9 ± 11.9) d,P＜ 0.05].Multiple Logistic regression analysis showed that gender,age,tumor location,histological differentiation,Dukes stages,surgical and colorectal cancer complications unrelated (P ＞ 0.05),NRS2002 score associated with colorectal cancer complications (P ＜ 0.05).Pearson correlation analysis showed that hospital stay correlated with NRS2002 score (P ＜ 0.01).Conclusions NRS2002 score is applicable in Chinese colorectal cancer patients.The youth and the elderly,the proximal part of colon,and Dukes D stage patients are more liable to develop preoperative nutritional risk than those of middle age,the distal part of colon,or other Dukes stages.≥ 3 scores predicts higher postoperative complications and longer hospital stay.Preoperative nutritional support is necessary in patients with ≥ 3 scores.
