Objective: This study aimed to summarize the current evidence-based approach to perioperative enteral nutritional (EN) program for gastric cancer (GC) surgery and to develop a staged and operable EN management scheme based on the evidence to provide clinical guidance for improving perioperative EN management in patients with GC.Methods: First, we synthesized expert consensuses, systematic reviews, and guidelines related to GC patients who had undergone surgery, based on a review of the literature and expert meetings. Subsequently, after carefully evaluating and selecting relevant EN management data, we created a preliminary draft of a perioperative EN program. Following Delphi expert consultations, the final version of the perioperative EN program was constructed after revision.Results: After two rounds of consultation, the expert opinions tended to be consistent. The expert positive coefficient was 1.00, and the expert authority coefficient was 0.90. After the second round of consultation, the coefficient of variation of the importance score ranged from 0.05 to 0.20, and the coefficient of variation of the feasibility score ranged from 0.09 to 0.23. The Kendall harmony coefficients were 0.338 and 0.392, and the difference between them was statistically significant (p < 0.001). The final practice plan includes 4 first-level, 16 s-level, and 64 third-level items.Conclusions: The perioperative EN program constructed in this study is comprehensive in content, feasible, and evidence-based, and can provide insights for clinical improvement.
