ePub Purpose:
The aim of this study was to elucidate the patterns of calorie support during the immediate postoperative period following a gastrectomy in gastric cancer patients.
Materials and Methods:
The clinicopathologic characteristics and nutritional parameters, including the actual infused amount of calories during the immediate postoperative period, were retrospectively collected and analyzed, This was data from a total 1,390 cases out of 1,404 patients who underwent curative gastrectomy at Samsung Medical Center, from Jan. 1 2016 through Dec. 31, 2016.
Results:
The actual infused amount of calories during the immediate postoperative period (the first three days following surgery) was only 41.6% of the recommended average intake of calories, which was significantly lower (759.8±139.4 kcal/day vs 1,825.7±251.6 kcal/day, respectively). The target calories supply per unit body weight was 30 kcal/kg. According to the operative method, the average infused amount of calories was lower in open gastrectomy compared to when utilizing the minimal invasive methods (laparoscopic assisted or robot assisted gastrectomy) (742.11 kcal/day:11.7 kcal/kg vs 792.95 kacl/day:12.8 kcal/kg or 791.43 kcal/day:12.8 kcal/kg, respectively). In regards to the operative type, the average infused amount of calories was higher in subtotal gastrectomy compared to that in total gastrectomy (732.1 kcal/day:12.23 kcal/kg vs 689.5 kcal/day:11.7 kcal/kg, respectively). The female group had a higher calorie supply per unit body weight compared to that of the male group (766.0 kcal/day:13.7 kcal/kg vs 758.9 kcal/day:11.3 kcal/kg, respectively). According to body mass index (BMI), the low BMI group had a lower calorie intake compared to that of the normal or high BMI group (700.2 kcal/day:15.3 kcal/kg vs 761.8 kcal/day:13.6 kcal/kg vs 766.5 kcal/day:11.1 kcal/kg, respectively). The actual infused amount of calorie significantly varied day by day in all the groups (range: 31.52 kcal/day to 1,559.31 kcal/day).
Conclusion:
The actual calorie intake significantly varied from day-to-day. Moreover, the intake was significantly lower than the average daily recommended amount of calories following a gastrectomy in gastric cancer patients during the immediate postoperative period.
