Our aim was to estimate the efficacy of laparoscopic and open Nissen fundoplication (ONF) in the treatment of gastroesophageal reflux disease (GERD) in children. An electronic systematic review of the published literature was conducted in Cochrane Library, MEDLINE (PubMed), and EmBase in October 2015 in English and without time restrictions. The participants, interventions, and comparisons in the clinical question translated directly into eligibility criteria for study inclusion and exclusion. Study information extraction and methodological quality assessments were accomplished by two reviewers independently. Methodological quality was assessed by using the “Criteria for judging risk of bias in the ‘Risk of bias’ assessment tool.” Odds ratio (OR) with 95 per cent confidence interval was computed as summary statistics. Fixed-effects model was used and a pooled OR was calculated with the Mantel‐Haenszel method initially. If the studies were heterogeneous, then the DerSimonian and Laird random effects model was used for meta-analysis. Outcome indices included mortality of patients, recurrence of GERD, reoperation of GERD, patients with complications, length of postoperative hospital stay, and surgery duration of laparoscopic Nissen fundoplication (LNF) and ONF. Statistical analyses were carried out by using Review Manager 5.2. The duration of follow-up varied between two days and four years. Children operated with LNF had a higher recurrence rate of GERD than those undergoing ONF. The pooled OR of LNF versus ONF was 2.98 (95% confidence interval = 1.29‐6.87) while the heterogeneity was I 2 = 47 per cent and P = 0.13. Statistical analysis showed that there was no significant difference for mortality, reoperation, and complication. The mean duration of surgery was significantly longer in the LNF than the ONF group while the results of length of postoperative hospital stay remained inconformity. In this meta-analysis, children operated with LNF had a higher recurrence rate of GERD than those undergoing ONF. Meanwhile, when considering the outcomes of mortality, reoperation, and complications, there was no significant difference. The mean duration of surgery was significantly longer in the LNF than the ONF group while no consistent conclusion of length of postoperative hospital stay was found.
