摘要:This study was to assess the resting energy expenditure of patients with esophageal cancer using indirect calorimetry. Eight male patients with esophageal cancer and eight male healthy controls were enrolled in this study. All patients underwent transthoracic esophagectomy with lymph nodes dissections. The resting energy expenditure was measured preoperatively, and on postoperative day 7 and 14 using indirect calorimetry. Preoperatively, the measured resting energy expenditure/body weight in these patients was significantly higher than that of the controls (23.3 ± 2.1 kcal/kg/day vs 20.4 ± 1.6 kcal/kg/day), whereas the measured/predicted energy expenditure from the Harris-Benedict equation ratio was 1.01 ± 0.09, which did not differ significantly from the control values. The measured resting energy expenditure/body weight was 27.3 ± 3.5 kcal/kg/day on postoperative day 7, and 23.7 ± 5.07 kcal/kg/day on postoperative day 14. Significant increases in the measured resting energy expenditure were observed on postoperative day 7, and the measured/predicted energy expenditure ratio was 1.17 ± 0.15. In conclusion, patients with operable esophageal cancers were almost normometabolic before surgery. On the other hand, the patients showed a hyper-metabolic status after esophagectomy. We recommended that nutritional management based on 33 kcal/body weight/day (calculated by the measured resting energy expenditure × active factor 1.2–1.3) may be optimal for patients undergoing esophagectomy.
