Impact of perioperative enteral immunonutrition in patients with gastrointestinal cancer undergoing elective surgery: a randomized controlled trial

Rationale: Major cancer surgery poses a significant risk to patient’s nutritional intake, especially among gastrointestinal cancer patients. Patients are often at high risk of a remarkable weight loss and impaired functional capacity after surgery. The aim of our study is to investigate the effects of two immune-modulating formulas on nutritional status and functional capacities in patients undergoing elective surgery.
