Purpose
Delayed enteral feeding (DEF) contributes to postoperative complications among children undergoing intestinal surgery. Various recent studies indicate the benefits of early enteral nutrition after intestinal surgery in adults. This systematic review and meta-analysis evaluates whether early enteral feeding (EEF) is beneficial in children who underwent intestinal anastomosis.
Methods
MEDLINE, PubMed, the Cochrane Library, and Web of Science databases were searched for RCTs that addressed the effect of EEF in children (younger than 18 years old) undergoing intestinal anastomosis. EEF was defined as starting enteral feeding before the 3rd postoperative day. Studies were selected based on predetermined inclusion and exclusion criteria. A meta-analysis was performed using RevMan 5.3 to estimate odds ratios (ORs) or mean differences (MDs) with 95% confidence intervals (CIs).
Results
Four RCT studies met the inclusion criteria, comprising 97 cases with EEF and 89 cases with DEF. Enteral feeding started significantly earlier in the EEF group compared to the DEF group (MD = − 2.80; 95% CI − 3.11 to − 2.49; p < 0.00001). Postoperative anastomotic leak rate was unchanged between EEF and DEF groups (OR = 0.86; 95% CI 0.17–4.46; p = 0.86). The EEF group had a shorter length of hospital stay (MD = − 3.38; 95% CI − 4.29 to − 2.48; p < 0.00001), earlier time to bowel movement return (MD = − 0.57; 95% CI − 0.79 to − 0.35; p < 0.00001), lower incidence of surgical infection (OR = 0.27; 95% CI 0.08–0.90; p = 0.03), and faster tolerance of full enteral feeding (MD = − 2.00; 95% CI − 3.01 to − 2.79; p < 0.00001). Incidence of fever (OR = 0.37; 95% CI 0.10–1.31; p = 0.12), emesis, and abdominal distention (OR = 0.63; 95% CI 0.13–3.16; p = 0.58) were not different between the two groups.
Conclusions
Early enteral feeding after intestinal anastomosis in children does not increase the risk of postoperative anastomotic leak, fever, emesis, and abdominal distention. However, early enteral feeding is beneficial as it promotes the return of bowel function, reduces the length of hospital stay and the incidence of surgical infection in comparison to delayed enteral feeding.
