Endoscopic full-thickness plication for the treatment of PPI-dependent GERD: results from a randomised, sham controlled trial. Issue 4 (13th April 2021) - Kalapala, Rakesh
Abstract : Background: The majority of endoscopic antireflux procedures for GERD are cumbersome to use and randomised long-term data are sparse. We conducted such a trial to determine the efficacy and safety of a novel, easy to use endoscopic full-thickness fundoplication (EFTP) device in patients with GERD. Design: Patients with proton pump inhibitor (PPI)-dependent GERD were randomised to either EFTP or a sham procedure in 1:1 ratio. The primary endpoint was ≥50% improvement in the health-related quality of life (GERD-HRQL) score at 3 months. Secondary end points included improvement in GERD-HRQL, reflux symptom scores, PPI usage, oesophageal acid exposure and reflux episodes and endoscopic findings at 3, 6 and 12 months. Results: Seventy patients were randomised; 35 in each group with a median (IQR) age of 36 (29–42) years, 71.4% males. 70% had non-erosive reflux disease on endoscopy with a mean DeMeester score of 18.9 (±19.93). The mean (±SD) duration of EFTP procedure was 17.4 (±4) min. The primary end point was more frequently achieved in the EFTP group (65.7% vs 2.9%; p<0.001). Median (IQR) % improvement in GERD-HRQL was significantly higher in the EFTP group at 6 (81.4 (60.9–100.0) versus 8.0 (2.2–21.6); p<0.001) and 12 (92.3 (84.4–100.0) versus 9.1 (4.8–36.0); p<0.001) months. In the EFTP group, 62.8% patients were off-PPI at 12 months compared with 11.4% in the sham group (p<0.001). pH-metry parameters partially improved at 3 months, (n=70; total reflux episodes in EFTP arm and non-acid reflux episodes for EFTP vs sham) but not at 12 months (n=27); endoscopic oesophagitis was seen in 0% in the treatment (n=18) and 5 (29.4%) in the control group (n=17) at 12 months. No major procedure-related adverse events were encountered in either group. Conclusion: EFTP using a novel device is safe and effective in improving quality of life in patients with PPI dependent mostly non-erosive reflux disease at short and long terms; objective parameters showed a limited response rate.
