SYSTEMATIC REVIEW
Systematic review and meta-analysis of safety and efficacy of early enteral nutrition as an isolated component of Enhanced Recovery After Surgery [ERAS] in children after bowel anastomosis surgery.
Journal of Pediatric Surgery 2022 August
BACKGROUND: Postoperative feeding practices are not uniform in children undergoing bowel anastomosis surgery. Primary aim of this review was to evaluate the safety and efficacy of early enteral nutrition (EEN) as an isolated component of enhanced recovery in children undergoing bowel anastomosis surgery.
METHODS: Medical search engines (PubMed, CENTRAL, Google scholar) were accessed from inception to January 2021. Randomized Controlled Trials (RCT)s, non-randomized controlled trials, observational studies and retrospective studies comparing EEN, initiated within 48 h vs late enteral nutrition (LEN), initiated after 48 h in children ≤ 18 years undergoing bowel anastomosis surgery were included. Primary outcome measure was the incidence of postoperative complications (anastomotic leak, abdominal distension, surgical site infection, wound dehiscence, vomiting and septic complications). Secondary outcome measures were the time to passage of first feces and the length of hospital stay.
RESULTS: Twelve hundred and eighty-six children from 10 studies were included in this review. No difference was seen between the EEN and LEN groups in the incidence of anastomotic leak (1.69% vs 4.13%; p = 0.06), abdominal distention (13.87% vs 12.31%; p = 0.57), wound dehiscence (3.07% vs 2.69%; p = 0.69) or vomiting (8.11% vs 8.67%; p = 0.98). The incidence of surgical site infections (7.51% vs 11.72%; p = 0.04), septic complications (14.02% vs 26.22%; p = 0.02) as well as pooled overall complications (8.11% vs 11.27%; RR 0.71; 95% CI = 0.56 to 0.89; p = 0.003; I2 = 33%) were significantly lower in the EEN group. The time to passage of first feces (MD - 17.23 h; 95% CI -23.13 to -11.34; p < 0.00001; I2 = 49%) and the length of hospital stay (MD -2.95 days; 95% CI -3.73 to -2.17; p < 0.00001; I2 = 93%) were significantly less in the EEN group.
CONCLUSION: EEN is safe and effective in children following bowel anastomosis surgery and is associated with a lower overall incidence of complications as compared to LEN. EEN also promotes early bowel recovery and hospital discharge. However, further well designed RCTs are required to validate these findings.
