Wound infection prevention strategies in colorectal endoscopic mucosal resection: A meta‐analysis of prophylactic measures.

Colorectal endoscopic mucosal resection (EMR) is associated with the risk of postoperative wound infections, prompting investigations into effective prophylactic measures. This meta‐analysis aimed to evaluate the efficacy of various prophylactic interventions in reducing the incidence of wound infections following EMR. Adhering to PRISMA guidelines, we conducted a comprehensive search across multiple databases for randomized controlled trials (RCTs) and cohort studies from 2015 to 2022. We included studies that compared the efficacy of antibiotic prophylaxis and antiseptic measures, with clear data on post‐procedure infection rates. Eight studies met our inclusion criteria, and data were extracted for meta‐analysis. The risk of bias was assessed using the Cochrane Collaboration tool and the Newcastle‐Ottawa Scale. The meta‐analysis included 3765 patients from eight RCTs. Prophylactic antibiotics (cefixime and cefuroxime) showed moderate to high efficacy, with infection rates as low as 0% and 0.76%. Prophylactic endoscopic closure and clipping showed the highest efficacy, with zero reported infections. The standardized surgical site infection prevention bundle had lower effectiveness, with an infection incidence of 3.83%. The risk of bias assessment indicated potential performance bias due to lack of blinding, but overall evidence quality was upheld by proper random sequence generation and diligent outcome data monitoring. The effectiveness of specific prophylactic measures, notably prophylactic antibiotics and mechanical closure techniques, has been shown in significantly reducing the risk of wound infections following colorectal EMR.
