Best Evidence Summary of Preoperative Management for Patients Undergoing Intestinal Stoma Surgery

To retrieve, evaluate, and synthesize the best evidence on preoperative management for patients with intestinal stomas, and to provide a foundation for clinical nursing practice.

This study was an evidence summary followed by the evidence summary reporting standard of Fudan University Center for Evidence-based Nursing. The PIPOST framework was used to establish the clinical question. A systematic search was performed according to the 6S evidence hierarchy across international and Chinese databases and guideline repositories from inception to July 31, 2025. Eligible evidence included clinical decision support documents, clinical practice guidelines, systematic reviews, expert consensus statements, position statements, organizational standards, and evidence summaries published in Chinese or English. Methodological quality was appraised using appropriate tools based on evidence type, and evidence was extracted, synthesized, and graded according to established evidence-based criteria.

A total of 46 evidence sources were included, comprising 5 clinical decision support documents, 10 clinical practice guidelines, 14 evidence summaries, 9 systematic reviews, 4 expert consensus statements, 3 position statements, and 1 organizational standard. Based on evidence synthesis and consultation with clinical professionals, 22 pieces of evidence were summarized across four domains: organizational preparation, comprehensive assessment, counselling and education, and stoma site marking.

This evidence summary provides an evidence-based framework to guide standardized and individualized preoperative care, aiming to improve surgical preparedness and postoperative outcomes. Further research is needed to update the evidence base and evaluate the feasibility and effectiveness of these recommendations in clinical practice.
