Effect of nutritional risk on short-term outcomes after laparoscopic-assisted gastrectomy: a prospective study from...

The aim of this prospective double-center study was to explore the effect of nutritional risk on short-term outcomes in the patients who had gastric cancer and underwent a laparoscopic-assisted gastrectomy.

We conducted a study of patients who underwent laparoscopic-assisted gastrectomy in two large centers between June 2014 and April 2017. Patients' demographic and clinical characteristics and postoperative short-term outcomes were prospectively analyzed. Patients were divided into two groups depend on the preoperative presence of nutritional risk. Clinical variables were compared. Univariate analyses and multivariate logistic regression analyses evaluating the risk factors for postoperative complications were performed.

A total of 256 patients, comprising 187 males and 69 females, met the inclusion criteria and were included in this study. The mean age was 61.81 years, the average BMI was 22.44 kg/m, and the average preoperative serum albumin was 39.42 g/l. Older age (P=0.001), higher tumor stage (P=0.047), lower BMI (P<0.001), lower preoperative serum albumin (P=0.005), and lower hemoglobin (P=0.013) were more common in the nutritional risk group. There were no significant differences in the short-term postoperative outcomes between nutritional risk and non-nutritional risk groups. Advanced age (P=0.024) and hypoalbuminemia (P=0.004) were independent risk factors for postoperative complications after laparoscopic-assisted gastrectomy.

Nutritional risk may not be a clinical predictor of short-term outcomes after laparoscopic-assisted gastrectomy. Advanced age and preoperative hypoalbuminemia were independent risk factors for grade II or more postoperative complications.
