Effect of nutritional treatment of esophageal cancer patients on pre and post-operative hemodynamic changes and postoperative lung complications

In 35 patients with esophageal cancer, preoperative nutritional state and hemodynamic changes on exercise test using Swan-Ganz catheter were studied. Thirty-five patients were divided into two groups. Group 1; preoperative daily calorie intake was less than 1.75 X BEE (basal energy expenditure), Group 2; preoperative daily calorie intake was more than 1.75 X BEE. There were significant differences between Group 1 and Group 2 in preoperative daily calorie intake, serum transferrin, retinal binding protein, pre-albumin and total lymphocyte count. From this result, Group 1 was thought to be malnutritional state, but nutritional state of Group 2 was thought to be improved. From the analysis of the hemodynamic changes on exercise test using Swan-ganz catheter, the cardiac function was better in Group 2 than in Group 1. The difference of the cardiac function was thought to be brought by the difference of nutritional state. In postoperative hemodynamic changes, Group 2 was better than Group 1 and in the occurrence of lung complications, Group 2 was much less than Group 1. These results was thought to be due to the difference of cardiac function brought by differences of nutritional state.
