🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. Efficacy of Baclofen as Add-on Therapy for Refractory Gastroesophageal Reflux Disease: A Meta-analysis.

Journal of clinical gastroenterology (2025) - Meta-Analysis

Key Findings

  • Baclofen add-on therapy improved GERD-Q symptom scores versus PPI therapy alone (SMD -0.78, 95% CI -1.06 to -0.51; I2=0%).
  • Adjunctive baclofen reduced nonacid reflux episodes (SMD -0.93, 95% CI -1.49 to -0.37) and improved DeMeester scores (SMD -0.82, 95% CI -1.61 to -0.04).
  • Acid reflux episodes were not significantly reduced versus control (SMD -0.12, 95% CI -0.49 to 0.19).

📋 Practice Implication: Baclofen is a reasonable short-term adjunct for refractory GERD when nonacid reflux is suspected, but it should not be framed as a substitute for acid suppression.

2. Vonoprazan Versus Lansoprazole in the Healing and Maintenance Phase of Erosive Esophagitis: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

Digestive diseases and sciences (2025) - Network Meta-Analysis

Key Findings

  • Vonoprazan achieved higher week-2 endoscopic healing than lansoprazole overall (RR 1.09, 95% CI 1.04-1.13; p<0.0001).
  • In severe erosive esophagitis (LA C/D), vonoprazan improved healing at week 2 (RR 1.26, 95% CI 1.15-1.38) and week 8 (RR 1.13, 95% CI 1.03-1.24).
  • Vonoprazan 20 mg reduced maintenance-phase recurrence versus lansoprazole 15 mg (RR 0.41, 95% CI 0.17-0.85) with no significant increase in TEAEs.

📋 Practice Implication: For erosive esophagitis, especially LA grade C or D disease, vonoprazan is a strong option when faster healing or more durable remission is the priority.

3. The efficacy of antireflux mucosectomy (ARMS) and antireflux mucosal ablation (ARMA) for gastroesophageal reflux disease (GERD) by 24-h pH monitoring: systematic review and meta-analysis.

Surgical endoscopy (2025) - Meta-Analysis

Key Findings

  • ARMA significantly reduced median acid exposure time after treatment (SMD -20.74, 95% CI -25.51 to -15.97; p<0.0001).
  • ARMS significantly improved DeMeester scores (SMD -2.79, 95% CI -4.33 to -1.26; p<0.0001).
  • Clinical success reached 78% for ARMS and 87% for ARMA.

📋 Practice Implication: In PPI-refractory GERD, ARMS or ARMA can be considered as less invasive escalation pathways before committing selected patients to formal antireflux surgery.

4. Fundoplication significantly improves objective and subjective reflux outcomes-a meta-analysis.

Surgical endoscopy (2025) - Meta-Analysis

Key Findings

  • Across 9516 patients, antireflux procedures produced statistically significant improvement in acid exposure time, DeMeester score, and relief scores.
  • Compared with Nissen fundoplication, TIF showed less improvement in acid exposure time (MD -4.06, 95% CI -8.03 to -0.09; p=.045) and DeMeester score (MD -20.60, 95% CI -38.33 to -2.88; p=.023).
  • MSA and Toupet fundoplication produced better symptom relief scores than Nissen (SMD 0.28, 95% CI 0.01-0.56 and SMD 0.17, 95% CI 0.01-0.32, respectively).

📋 Practice Implication: Procedure selection should match the dominant treatment goal: Nissen for stronger acid control, versus Toupet or MSA when postoperative symptom relief profile is more important.

5. A systematic review and meta-analysis of randomized controlled trials: the role of potassium-competitive acid blockers in endoscopy-negative reflux disease.

Digestive and liver disease (2025) - Meta-Analysis

Key Findings

  • In endoscopy-negative reflux disease, PCABs increased heartburn resolution versus placebo (RR 1.43, 95% CI 1.22-1.68).
  • PCABs reduced mean heartburn severity at 4 weeks (SMD 0.19, 95% CI -0.35 to -0.02).
  • Treatment-emergent adverse events were comparable to placebo (OR 1.06, 95% CI 0.82-1.37).

📋 Practice Implication: For symptomatic ENRD, PCABs appear to offer a clinically useful pharmacologic option when conventional PPI response has been unsatisfactory or inconsistent.

💡 Summary

Recent GERD evidence emphasizes stronger acid suppression with potassium-competitive acid blockers, incremental benefit from baclofen in refractory disease, and meaningful gains from endoscopic or surgical antireflux interventions. Across erosive and endoscopy-negative phenotypes, the most actionable signals were higher healing or heartburn-resolution rates without major safety penalties, while procedure choice still requires balancing symptom control against dysphagia, gas-related effects, and long-term durability.
