Official Title: Effects of Immunonutrition on Surgical Site Infection and Th1/Th2/Th17 Differentiation in Patients Undergoing Pancreaticoduodenectomy

Further study details as provided by Chiba University:

Primary Outcome Measures:
  • surgical site infection after surgery [ Time Frame: 30days ]

Secondary Outcome Measures:
  • plasma IL-6, CRP, Th1/Th2 balance, Th17 status [ Time Frame: 14 days ]

Enrollment: 30
Study Start Date: May 2006
Study Completion Date: September 2008
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
Group A: perioperative immunonutrition
Dietary Supplement: Oral IMPACT
oral supplementation for 5 days(1 L/d )before surgery of a formula enriched with arginine, omega-3 fatty acids, and RNA
Other Name: oral IMPACT; Ajinomoto Pharma Co., Ltd, Tokyo, Japan
Active Comparator: 2
Group B: postoperative immunonutrition
Dietary Supplement: Oral IMPACT
postoperative enteral infusion of the formula with arginine, omega-3 fatty acids, and RNA
Active Comparator: 3
Group C: control
Dietary Supplement: Parenteral nutrition
Parenteral nutrition

Detailed Description:

Perioperative immunonutrition is reported to improve the incidence of postoperative infectious complication in patients with gastrointestinal surgery. It has also been recognized that Th1/Th2 balance shifts toward Th2 by surgical stress. On the other hand, the change of Th17 status after surgery has not been established. Furthermore, The change of Th1/Th2 balance and Th17 status with immunonutrition on pancreaticoduodenectomy have not been reported yet.

Objective of this study is to investigate the effects of perioperative immunonutrition on incidence of postoperative infectious complication, Th1/Th2 balance and Th17 status after pancreaticoduodenectomy.
