The effect of preoperative stoma site marking on risk of stoma-related complications in patients with intestinal ostomy - A systematic review and meta-analysis.

Aim: This systematic review and meta-analysis aimed to investigate the effect of preoperative stoma site marking on stoma-related complications in patients with intestinal ostomy.

Methods: MEDLINE, Embase, CENTRAL, CINHAL, and Google Scholar were searched up to August 2021 for randomised controlled trials (RCTs) and nonrandomised studies of interventions (NRSI) that involved patients with intestinal ostomies comparing preoperative stoma site marking to no marking and which reported at least one patient-relevant outcome. Outcomes were prioritised by stakeholder involvement.
