Abstract: Objective: To develop and implement a stoma leakage prevention protocol based on body morphology assessment, aiming to provide reference for clinical practice. Methods: A stoma leakage prevention protocol based on body morphology assessment was formulated through literature review and expert consultation. Using convenience sampling, patients with intestinal stomas admitted to a tertiary grade A cancer specialty hospital in Henan province from January to June 2025 were enrolled. The control group (n=44) received conventional stoma care, while the intervention group (n=44) implemented the morphology assessment-based leakage prevention protocol. The two groups were compared regarding postoperative stoma leakage incidence, peristomal skin complication rates, and nursing satisfaction. Results: At 1 week postoperatively, the leakage rate in the intervention group was significantly lower than that in the control group (P<0.05), a continuous downward trend was observed at 4 and 8 weeks postoperatively, but the difference was not statistically significant (P>0.05). The incidence of skin complications at 4 and 8 weeks postoperatively was significantly lower in the intervention group than in the control group (P<0.05). At 8 weeks postoperatively, the total nursing satisfaction score was significantly higher in the intervention group than in the control group (P<0.001). Conclusion: A stoma leakage prevention program based on body morphology assessment effectively reduces the risk of early postoperative leakage in ileostomy patients, significantly decreases skin complications, and enhances patient nursing satisfaction.
