Abstract
Objective To evaluate the safety and effect of enteral nutrition support at early period after gastroenteric operation. Methods 62 patients with gastrointestinal cancer were divided into three groups randomly: control group, TPN group, and TEN group. Patients in TPN and TEN groups received 7 days nutritional support in isonitrogenous and isocaloric. The peripheral vein blood was sampled before operation and 7 day after that to observe nutritional status and T lymphocyte subsets, NK cells, and NK cell activity. Resalts There were no significant difference in the three groups in albumin and anthropomentric measurement, visceral proteins decreased in three groups in postoperative period, but the values of control group was more seriously than TPN or TEN groups (P<0.05). Mean nitrogen balance: - 8.6 ± 3.12g/day in control group, - 4.22 ± 2.02g/day in TPN group, - 3.88 ± 2.35g/day in TEN group (P<0.05). CD3 ,CD4 ,CD4/CD8, NK cells and NK cell activity decreased in postoperative period in three groups, but there are no significant ditference in three groups. Conelasions Enteral nutrition support at early period after gastroenteric operation is safety and effective.
