Serial changes in contribution of substrates to energy expenditure after transthoracic esophagectomy for cancer.
This study was designed to examine the metabolic response of patients following transthoracic esophagectomy for carcinoma of the esophagus during the administration of total parenteral nutrition. Thirty-five patients underwent a right thoracotomy and transthoracic esophagectomy with nodal dissection in the neck, mediastinum, and abdomen. The resting energy expenditure (REE) was measured preoperatively, and on the 1st, 3rd, 5th, and 7th postoperative days (PODs) using indirect calorimetry. The REE was significantly higher following transthoracic esophagectomy on PODs 1, 3, 5, and 7 than preoperatively. The caloric contribution of fat was significantly less on 3rd, 5th, and 7th PODs than on the 1st POD. In contrast, carbohydrate oxidation increased significantly on the 3rd, 5th, and 7th PODs compared to that of the 1st POD. These results may help optimize the nutritional support regimen for post-esophagectomy patients.
