Purpose

The aim of this trial is to compare preoperative Imunnonutrition with standard enteral nutrition regarding morbidity after major abdominal surgery in patients with NRS greater 3.

The primary end point is the complication rate until 30 days after surgery.

Condition	Intervention
Major Abdominal Surgery	Dietary Supplement: Immunonutrition for 5 days preoperative Dietary Supplement: Standard enteral nutrition for 5 days preoperative


Study Type:	Interventional
Study Design:	Allocation: Randomized Endpoint Classification: Efficacy Study Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor) Primary Purpose: Treatment
Official Title:	Immunonutrition Versus Standard Enteral Nutrition Before Major Surgery: A Single-center Double-blinded Controlled Randomized Superiority Trial

Arms	Assigned Interventions
Active Comparator: 1 Immunonutrition containing RNA, omega-3-FAs, arginine	Dietary Supplement: Immunonutrition for 5 days preoperative Impact vs Meritene Other Name: Impact, Meritene
Active Comparator: 2 Standard enteral nutrition: isocaloric and isonitrogeneous but w/o active ingredients	Dietary Supplement: Standard enteral nutrition for 5 days preoperative Impact vs Meritene Other Name: Impact vs Meritene

Detailed Description:

Malnutrition affects about 20-50% of all patients in hospital [1, 2]. Major surgery further increases postoperative malnutrition and immunity reduction. Therefore, postoperative complication and infection rates after major surgery exceed 30% [3-6].

The nutritional risk score (NRS) [1] is based on the ESPEN (European society of parenteral and enteral nutrition) screening guidelines and identifies patients who are likely to benefit from nutritional support. Patients with a NRS ≥ 3 are considered severely undernourished, or to have a certain degree of severity of disease in combination with certain degree of malnutrition [7].

In a prospective cohort study patients with a NRS ³ 3 had significant more infectious and overall complications after major abdominal surgery [4, 7, 8]. Several studies showed a benefit by nutritional support on complications [3, 5, 6]. International guidelines suggest therefore preoperative oral nutritional support for malnourished patients undergoing major surgery [9]. However, it remains controversial whether standard enteral nutrition (SEN) or immunonutrition (IN) is preferable [9].

IN, containing arginine, ribonucleic acid and omega-3 polyunsaturated fatty acids aims to improve the nutritional status, immunological function and clinical outcome [5, 10].
