SP 10.08 Impact of Stoma Marking on Outcome in Emergency Surgery - A Single-Centred Cohort Study
Aelly Rashidah Boey, Hwei Jene NgAbstract
Background/Aim
Emergency stoma formation is associated with high risk of post-operative morbidity. Pre-operative stoma site marking (PoSSM) has shown to improve outcomes in elective setting. However, evidence in emergency laparotomy (EmLap) is limited. This study aimed to evaluate the impact of PoSSM on post-operative outcome in EmLap patients.
Methods
Prospective data on EmLap patients were collected from a single-centre between August’24 and August’25, with ≥ 3 months follow-up. EmLap patients meeting NELA criteria requiring emergency stoma formation were included. Data collected included demographics, EmLap indication, stoma type, presence and provider of PoSSM, post-operative complications, post-operative length of stay (LOS) and 30-day readmission rates. Statistical significance was defined as p<0.05.
Result
Of 179 EmLap patients, 100 (56%) had stoma formation (46 ileostomies, 43 colostomies, 11 others). 54 patients had PoSSM (44 by stoma nurses, 10 by surgical trainees). Compared with unmarked patients, PoSSM group demonstrated improved outcomes including lower complication rates (63% vs.86%, p=0.24), shorter median LOS (14 vs.26 days, p=0.02), and lower 30-day readmission rates (13% vs.16% , p=0.64). No significant differences in post-operative outcomes were observed between stoma nurse- and surgical trainees-marked group, complication rates (74% vs.50%, p=0.16), median LOS (14 vs.15 days, p=0.72), and 30-day readmission rates (16% vs.0%, p=0.18).
Conclusion
PoSSM was associated with improved post-operative outcomes in emergency stoma formation. No significant difference was observed between stoma marking performed by stoma-nurse and surgical-trainees. These findings highlight the importance of PoSSM in EmLap and the role of stoma site marking education in surgical training.
