Objective:

To evaluate the clinical efficacy of enteral immunonutrition (EIN) compared to standard enteral nutrition (EN) in patients undergoing gastric cancer surgery.

Approach:

Key Findings:

• Addspecificstatisticalmeasuresforclarity.

Interpretation:

Perioperative enteral immunonutrition, particularly when administered for 7–10 days, is associated with reduced postoperative complications, improved humoral immunity, and shorter hospital stay in patients undergoing gastric cancer surgery.

Limitations:

• Specifywhichsecondaryoutcomeshadlowcertainty.

Conclusion:

EIN may be considered as a component of perioperative nutritional support, particularly in patients with established nutritional risk, while routine use should be guided by individualized assessment and confirmed by larger high-quality multicenter trials.
