This systematic review and meta-analysis compared total fundoplication (Nissen) versus partial fundoplication (Toupet) in patients younger than 18 years with gastroesophageal reflux disease (GERD), including 2633 patients. The primary outcome was not reported; secondary outcomes included postoperative dysphagia, reflux recurrence, intraoperative and postoperative complications, reoperation rates, and mortality.
The pooled analysis showed that total fundoplication was associated with a significantly higher risk of postoperative dysphagia (RR 1.69, 95% CI 1.07-2.68, p=0.024), with an absolute risk increase of 5.7% and number needed to harm of 17. Reflux recurrence did not differ significantly between groups (RR 0.72, 95% CI 0.21-2.42, p=0.59), with absolute rates of 6.8% versus 13.7% (absolute risk reduction 6.9%, NNT 15). Intraoperative complications, postoperative complications, reoperation rates, and mortality were comparable between procedures, with no significant differences.
The authors noted moderate heterogeneity for some outcomes (I²=71% for reflux recurrence), and limitations were not reported. The pooled analysis establishes associations, not causality. Partial fundoplication may offer functional advantages in selected patients due to lower dysphagia risk, but individual patient factors should guide surgical choice.

INTRODUCTION: Gastroesophageal reflux disease (GERD) is a common condition in children requiring surgical intervention when medical therapy fails. Nissen (total) and Toupet (partial) fundoplications are the most frequently performed antireflux procedures; however, their comparative effectiveness and safety in the pediatric population remain uncertain.
METHODS: A systematic literature search was conducted in PubMed, Embase, and Cochrane CENTRAL from database inception to 2025. Eligible studies included randomized controlled trials and observational studies comparing total and partial fundoplication in patients younger than 18 years with GERD. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using random-effects models in R software.
RESULTS: Eighteen studies including 2,633 children were analyzed. Total fundoplication was associated with a significantly higher risk of postoperative dysphagia compared with partial fundoplication (RR 1.69; 95% CI 1.07-2.68; p = 0.024; I²=12%; n = 1,154), corresponding to an absolute risk increase of 5.7% and a number needed to harm (NNH) of 17. No significant difference was observed in reflux recurrence (RR 0.72; 95% CI 0.21-2.42; p = 0.59; I²=71% n = 834), although event rates were numerically lower after total fundoplication (6.8% vs. 13.7%), corresponding to an absolute risk reduction of 6.9% (NNT = 15). Intraoperative complications (RR 1.11; p = 0.84), postoperative complications (RR 1.49; p = 0.12), reoperation rates (RR 0.95; p = 0.88), and mortality (RR 1.09; p = 0.74) were comparable between procedures.
CONCLUSIONS: Total and partial fundoplication demonstrate similar effectiveness for reflux control and overall safety in pediatric GERD. However, total fundoplication is associated with a higher risk of postoperative dysphagia, suggesting that partial fundoplication may offer functional advantages in selected patients.
