The effects of enhanced recovery after surgery on wound infection, complications, and postoperative hospital stay in patients undergoing colorectal surgery: A systematic review and meta-analysis

This study aimed to systematically evaluate the effects of enhanced recovery after surgery (ERAS) on surgical site infections, postoperative complications, and length of hospital stay in patients undergoing colorectal surgery. A comprehensive search was conducted of PubMed, Web of Science, Ovid, EMBASE, The Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data from database inception to April 2023 to identify relevant studies on the application of ERAS in colorectal surgery. Studies were screened, and data were extracted based on predetermined inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software. A total of 22 studies, including 3702 patients (ERAS group: 1906; control group: 1796), were included in the final analysis. ERAS significantly reduced the incidence of surgical site infection (odds ratio [OR]: 0.49, 95% confidence interval [CI]: 0.34-0.69, p < 0.001), postoperative complications (OR: 0.33, 95% CI: 0.27-0.41, p < 0.001), and length of hospital stay (standardised mean difference: -1.22 days, 95% CI: -1.66 to -0.77 days, p < 0.001). These findings suggest that ERAS reduces the incidence of surgical site infections and postoperative complications and shortens the length of hospital stay in patients undergoing colorectal surgery. Therefore, ERAS should be promoted and applied in clinical practice.
