Background: Enhanced recovery after surgery (ERAS), as a new concept in surgery, has dramatically changed the mode of perioperative treatment for children with acute appendicitis., Methods: The retrieval strategy developed by the Cochrane Collaboration was conducted using the CNKI database, Wanfang Medical Network, PubMed, EBSCO, Medline, and Cochrane database by combining subject headings and free words. A review of the randomized controlled trials on the use of the ERAS concept in the perioperative treatment of acute appendicitis in children was conducted between the establishment of the database and May 15, 2021. Keywords included enhanced recovery after surgery, fast track surgery, ERAS, FTS, child, infant, and appendicitis. The quality of the literature was evaluated according to the RevMan 5.3 software provided by the Cochrane Collaboration., Results: Five randomized controlled trials on ERAS in children with acute appendicitis were finally included. The heterogeneity of postoperative stay time was tested in 4 studies using continuous variables, with Chi-squared test (Chi 2 ) =221.52, degree of freedom (df) =3, I 2 =99%>50%. An overall analysis using a random effects model showed that the ERAS group was significantly different compared to the control group [Z=5.26; mean difference (MD) =-1.65; 95% CI: -2.27 to -1.03; P<0.00001]. The heterogeneity of the readmission rate was tested in 5 studies using dichotomous variables, with Chi 2 =5.11, df =3, I 2 =41%<50%, P=0.91. Overall analysis using a fixed effects model showed no statistically significant difference between the ERAS group and the control group [Z=0.80; odds ratio (OR) =1.16; 95% CI: 0.81 to 1.66; P=0.42]. The heterogeneity of the recurrence rate was tested in 4 studies using dichotomous variables, with Chi 2 =3.73, df =3, I 2 =20%<50%, P=0.29. Overall analysis using a fixed effects model showed no statistically significant difference between the ERAS group and the control group (Z=1.14; OR =0.76; 95% CI: 0.47 to 1.22; P=0.26)., Discussion: The results of the meta-analysis confirmed that perioperative application of the ERAS concept in children with acute appendicitis can promote the rehabilitation of children, reduce the postoperative stay time, and reduce the readmission rate and reoperation rate., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://dx.doi.org/10.21037/tp-21-457).
