The incidence of postoperative complications was calculated. Postoperative recovery, nutritional indicators, inflammatory factors indicator, and the safety indicators before operation and at 1, 3, and 7 days after operation were compared. SPSS 29.0 statistical software was used for statistical analysis.Results: The incidence of postoperative overall complications in the control group and the observation group was 22.50% (27/120) and 17.24% (10/58), respectively, and there was no significant difference between the two groups (P=0.42). The incidence of postoperative complications of Clavien-Dindo grade ≥III in the control group and the observation group was 14.17% (17/120) and 3.45% (2/58), respectively, and the difference between the two groups was statistically significant (P=0.03). Secondary outcomes (first exhaust, defecation, and liquid diet intake times) were significantly recovered earlier in the observation group than those in the control group (P 0.05), although significant differences were observed in several inflammatory and safety indicators(P< 0.05).Conclusion: Unlike conventional nutritional support, postoperative parenteral Gln supplementation reduced the incidence of postoperative Clavien–Dindo complications grade ≥III in patients with CRC while increasing intestinal and immune functions, decreasing inflammation, and reducing the length of hospital stay.Keywords: glutamine, parenteral nutrition, colorectal cancer, clavien–dindo complication
