Efficacy of Laparoscopic Nissen Fundoplication vs Transoral Incisionless Fundoplication or Proton Pump Inhibitors in Patients With Gastroesophageal Reflux Disease: A Systematic Review and Network Meta-analysis
2018
Background & Aims The effects of transoral incisionless fundoplication (TIF) and laparoscopic Nissen fundoplication (LNF) have been compared with those of proton pump inhibitors (PPIs) or a sham procedure in patients with gastroesophageal reflux disease (GERD), but there has been no direct comparison of TIF vs LNF. We performed a systematic review and network meta-analysis of randomized controlled trials to compare the relative efficacies of TIF vs LNF in patients with GERD. Methods We searched publication databases and conference abstracts through May 10, 2017 for randomized controlled trials that compared the efficacy of TIF or LNF with that of a sham procedure or PPIs in patients with GERD. We performed a network meta-analysis using Bayesian methods under random-effects multiple treatment comparisons. We assessed ranking probability by surface under the cumulative ranking curve. Results Our search identified 7 trials comprising 1128 patients. Surface under the cumulative ranking curve ranking indicated TIF had highest probability of increasing patients' health-related quality of life (0.96), followed by LNF (0.66), a sham procedure (0.35), and PPIs (0.042). LNF had the highest probability of increasing percent time at pH Conclusions In a systematic review and network meta-analysis of trials of patients with GERD, we found LNF to have the greatest ability to improve physiologic parameters of GERD, including increased LES pressure and decreased percent time pH
