The Impact of Preoperative Immunonutrition and Standard Polymeric Supplements on Patient Outcomes After Pelvic Exenteration Surgery, Taking Compliance Into Consideration: A Randomized Controlled Trial.

Preoperative immunonutrition did not significantly impact length of stay or postoperative complications compared with standard polymeric supplements after pelvic exenteration surgery, despite controlling for protein, energy, and volume. Compliance, protein, and energy may considerably impact the effect of immunonutrition, particularly in malnourished patients.
