Abstract

Purpose

We aim to review and quantitatively compare laparoscopic Toupet fundoplication (LTF), Nissen fundoplication (LNF), anterior partial fundoplication (APF), magnetic augmentation sphincter (MSA), radiofrequency ablation (RFA), transoral incisionless fundoplication (TIF), proton pump inhibitor (PPI), and placebo for the treatment of GERD. A number of meta-analyses compared the efficacy of surgical and endoscopic procedures for recalcitrant GERD, but considerable debate on the effectiveness of operative strategies remains.

Methods

A systematic review of MEDLINE databases, EMBASE, and Web of Science for randomized controlled trials (RCTs) comparing the aforementioned surgical and endoscopic GERD treatments was performed. Risk ratio and weighted mean difference were used as pooled effect size measures, whereas 95% credible intervals (CrI) were used to assess relative inference.

Results

Thirty-three RCTs were included. Surgical and endoscopic treatments have similar RR for heartburn, regurgitation, bloating. LTF has a lower RR of post-operative dysphagia when compared to APF (RR 3.3; Crl 1.4–7.1) and LNF (RR 2.5; Crl 1.3–4.4). The pooled network meta-analysis did not observe any significant improvement regarding LES pressure and pH < from baseline. LTF, APF, LNF, MSA, RFA, and TIF had have a similar post-operative PPI discontinuation rate.

Conclusion

LTF has a lower rate of post-operative dysphagia when compared to APF and LNF. The pre-post effects, such as GERD-HQRL, LES pressure, and pH <4, should be avoided in meta-analyses because results may be biased. Last, a consensus about the evaluation of GERD treatments’ efficacy and their outcomes is needed.

Supplementary Figure 2.

The Ranking plot created using the rankogram function from R package applied to the three surgical approaches illustrating the empirical probability that each treatment is ranked 1st through 7th (left to right) for (E) improvement in pH<4 and (G) PPI discontinuation; and ranked 1st through 5th for (F) improvement in LES pressure. The abscissa axis shows the different treatments. The ordinate axis shows the probability (%) of ranking better (higher rankings associated with smaller outcomes values). (PNG 49 kb)
