Abstract: Objective To retrieve and summarize the relevant evidence of early oral feeding management in patients with esophageal cancer after surgery. Methods According to the evidence-based “6S” model to retrieve the evidence,we searched all the evidence about the management of early oral feeding in postoperative patients with esophageal cancer in UpToDate,BMJ Best Clinical Practice,Australia's Joanna Briggs Institute Evidence-based Practice Database,National Institute for Health and Care Excellence,CNKI,Wanfang Database,China Biomedical Literature Database and related websites or databases,including clinical decisions,guidelines,systematic reviews,meta-analysis,expert consensuses,evidence summaries,and randomized controlled trials. The retrieval time limit was from the establishment of the database to May 2022. The quality of the literature was evaluated independently by two researchers who had received systematic evidence-based nursing training,and the evidence meeting the quality standards was extracted and summarized based on the judgment of professionals. Results 14 literature were eventually included,including two clinical decisions,four guidelines,three expert consensuses,one systematic review and four randomized controlled trials. 24 pieces of best evidence were summarized from 4 aspects of early oral feeding:choice of timing,the evaluation of swallowing function,the formulation of eating plan,risk identification and prevention. Conclusion Early oral feeding is safe and feasible in postoperative patients with esophageal cancer. Nursing staff should select the best evidence based on clinical situation,facilitating factors and barriers of evidence application and patients' willingness,so as to provide scientific and evidence-based management programs for early oral feeding of patients after esophageal cancer surgery,which will accelerate postoperative recovery of patients,reduce complications and shorten hospital stay.
