Abstract: Objective: To retrieve, evaluate, and summarize evidence regarding the management of Transanal Irrigation in patients with spinal cord injury and Neurogenic Bowel Dysfunction, providing evidence-based support for clinical practice. Methods: Evidence-based questions were identified using the PIPOST model. A literature search was conducted using the "5S" model, covering relevant domestic and international academic societies, guidelines, and databases from database inception to November 30, 2025. The researchers conducted quality assessment and evidence extraction of the literatures, and summarized the relevant evidence in accordance with the principles of evidence synthesis and the Australian JBI Evidence Hierarchy System. Results: A total of 17 articles were included, comprising 2 clinical decision-making articles, 7 guidelines, 1 evidence summary, 2 expert consensus articles, 2 systematic reviews, 1 randomized controlled trial, and 2 quasi-experimental studies. Thirty-two pieces of evidence were summarized across seven dimensions: nursing standards, team training, pre-intervention assessment, key points of the intervention, complication management, post-intervention assessment and follow-up, and health education. Conclusion: The evidence summarized in this study possesses scientific validity and practical value, providing an evidence-based basis for healthcare professionals to manage patients with spinal cord injury and Neurogenic Bowel Dysfunction.
