ERAS and Gastrointestinal Site Infections: Insights from a Comprehensive Systematic Review and Meta-Analysis.

Abstract

Background: Enhanced recovery after surgery (ERAS) protocols are proposed to enhance perioperative care, but their impact on various surgical outcomes requires further insight. Objective: This extensive meta-analysis aimed to systematically estimate the effectiveness of ERAS in reducing postoperative complications and improving recovery metrics. Materials and Methods: We meticulously searched multiple databases and rigorously screened studies, ultimately including 16 high-quality research articles in our meta-analysis. We carefully assessed heterogeneity using the Cochran Q test and I² index. Results were visualized using forest plots, displaying effect sizes and 95% confidence intervals (CIs). Results: The current meta-analysis reveals compelling evidence of ERAS protocols' impact on postoperative effects. Lung infection rates were significantly reduced, with an odds ratio (OR) of 0.4393 (95% CI: 0.2674; 0.7216, p = 0.0012), highlighting the protocols' effectiveness. Although the reduction in surgical site infections (SSIs) was not significant, with an OR of 0.8003 (95% CI: 0.3908; 1.6389, p = 0.5425), the data suggests a trend toward benefit. Urinary tract infections (UTI) also showed a promising decrease, with an OR of 0.4754 (95% CI: 0.2028; 1.1143, p = 0.0871), revealing ERAS protocols may mitigate UTI risks. No significant effects were observed on postoperative anastomotic leakage or ileus, with ORs indicating neutrality. The incidence of readmission was similarly unaffected, with an OR of 1.4018 (95% CI: 0.6860; 2.8647, p = 0.3543). These outcomes underscore the selective efficacy of ERAS protocols, advocating for their strategic implementation to optimize surgical recovery. Conclusions: This meta-analysis offers compelling evidence supporting the implementation of ERAS in mitigating specific post-surgical conditions. It underscores the potential of ERAS to enhance recovery experiences and improve healthcare efficiency. Further targeted research is warranted to fully understand the impact of ERAS on SSI, anastomotic leakage, ileus, and readmissions and to optimize its benefits across diverse surgical populations.
