Postoperative energy intake in patients after colorectal cancer surgery.
In a prospective noninterventional study of 75 consecutive patients (mean age 71 +/- 12 years) undergoing surgery for colorectal cancer, standard postoperative energy intake was evaluated. Seventeen patients expended 40%-60% of estimated basal energy during hospitalization, 33 patients 60%-80%, 22 patients 80%-100% and three patients 100%-125%. Weight loss was observed in 67 patients (mean loss 4.7 +/- 4.4%) during hospitalization. Men had a significantly higher mean total calorie deficit (p < 0.001), and mean weight loss percentage (p < 0.01), compared to women. Preoperative nutritional status, nutrition-associated complications and length of hospital stay did not change the nutritional support and intake. Correlation analyses resulted in significant associations between gender and total calorie deficit (rs = 0.41, p < 0.01), postoperative weight loss and total calorie deficit (rs = -0.32, p < 0.01), and between postoperative weight loss and length of stay (rs = 0.27, p < 0.05). We concluded that the patients' energy intake was insufficient compared to estimated basal energy expenditure. These results suggest a need for individualized nutritional care, based on each patient's energy needs and on registration of daily calorie intake, all with the aim of increasing energy intake postoperatively in standard hospital care.
