Results: There were statistically significant differences in BMI, albumin, total cholesterol, and lymphocyte count between patients from the two groups (all P < 0.05). There was no difference in the incidence rate of postoperative complications between the two groups, but there was a statistically significant difference in the total number of complications (P < 0.05). There were no significant differences between the two groups regarding abdominal drainage volume, exhaust (flatus) time, hospitalization cost, morbidity, or 60 d readmission rate (all P > 0.05). However, patients with nutritional risk had higher postoperative blood transfusion volumes, albumin infusions, weight difference before and after surgery, and postoperative hospital stays than the nonnutritional risk group (all P < 0.05). Smoking, diabetes, and preoperative nutritional risk were the risk factors by the univariate and multivariate logistic regression analyses.
Conclusions: The postoperative complication rate was increased, and the short-term efficacy was decreased in the preoperative nutritional risk group compared with those without nutritional risk.
