Effects of Preoperative Immunonutrition in Patients Undergoing Hepatectomy

Effects of Preoperative Immunonutrition on Infectious Complication and Th1/Th2 Differentiation in Patients Undergoing Hepatectomy

The purpose of this study is to determine whether preoperative immunonutrition is effective on infectious complication and Th1/Th2 differentiation in patients with major hepatectomy.

The investigators reported that preoperative immunonutrition improve the incidence of postoperative infectious complication in patients after hepatectomy, and modulation of Th1/Th2 differentiation may play important roles in this effect.

Object of this study is to investigate the effects of preoperative immunonutrition on incidence of postoperative infectious complication, and Th1/Th2 balance after hepatectomy.
