Preoperative stoma site marking reduces postoperative stoma-related complications in emergency surgery: A single center retrospective cohort study.

Background and objective: Stoma site marking is an important factor in reducing stoma-related complications, thereby influencing the long-term quality of life in the elective setting. The impact of preoperative stoma site marking in emergency stoma creation is largely unknown. We aimed to determine whether preoperative stoma site marking in emergency stoma creation reduces stoma-related complications.

Methods: Patients who underwent emergency stoma creation at our hospital between 2009 and 2022 were examined by reviewing our prospective database and retrospective chart review. Subjects were classified into the "marking (+)" or "marking (-)" group according to stoma site marking (194 and 151 patients, respectively). The changes in the frequency of stoma marking over time and the effects of stoma marking on stoma-related complications were analyzed.

Results: The overall frequency of grade 2 or higher stoma-related complications was lower in the marking (+) group than in the marking (-) group (24% versus 36%, p = 0.010). Stoma site marking was associated with fewer soma site bleeding (2% versus 10%, p < 0.001), and the frequency of peristomal dermatitis was also lower (10%) in the marking (+) group (versus 18%, p = 0.042). Moreover, the lack of stoma site marking was an independent risk factor for overall stoma-related complications (adjusted odds ratio: 1.69, p = 0.034).

Conclusions: Preoperative stoma site marking was associated with stoma-related complications in emergency surgery. The clinical significance of our attempt is worth validating with prospective studies.
