Abstract Background Since radical cystectomy is associated with relatively high perioperative morbidity and mortality, this study was conducted to evaluate the efficacy of perioperative immune nutrition in radical cystectomy patients on postoperative outcomes including wound healing, postoperative complications, either infectious or non-infectious, and length of hospital stay. Patients and methods This prospective, randomized controlled study was conducted between June 2022 and November 2023. Forty-two patients who had undergone radical cystectomy with ileal conduit were randomized into two groups: the immune nutrition group, which received perioperative immune nutrition, and the conventional group, which did not receive immune nutrition. Patients were followed up for 30 days postoperatively to assess wound healing, infectious and non-infectious complications, and the length of hospital stay. Results Patients who received immune nutrition had significantly lower postoperative infectious complications (19.0 vs 61.9%; P = 0.004), shorter hospital stay (16.57 ± 3.74 vs 20.38 ± 5.97; P = 0.01) and shorter ICU stay (2.60 ± 1.07 vs 7.09 ± 7.50; P = 0.029). The proper wound healing was significantly higher in the immune nutrition group (90.5 vs 52.4%; P = 0.006). However, there was no significant difference between both groups in the rate of non-infectious complications (28.5% vs. 57.1%, P = 0.061). Conclusion Perioperative immune nutrition is associated with improved wound healing, reduced infectious complications, and reduced length of hospital stay.
