Study summary

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

Read the detailed description

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

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