Abstract
The purpose of the present study was to assess the long-term safety and durability of effect for endoscopic full-thickness plication for the treatment of symptomatic gastroesophageal reflux disease (GERD). The Plicator (NDO Surgical, Inc., Mansfield, MA) used delivers a transmural suture through the gastric cardia to restructure the antireflux barrier. Published reports have shown the Plicator procedure to be effective in reducing GERD symptoms and medication use at 1 year post-plication. Twenty-nine patients with chronic heartburn requiring maintenance daily anti-secretory therapy were treated at five sites. Patients received a single full-thickness plication in the gastric cardia 1cm below the gastroesophageal junction (GE) junction. Re-treatments were not permitted. Patients were evaluated at baseline for GERD symptoms and medication use. Intermediate (12 month) and long-term subject follow-up (median follow-up: 36.4 months; range, 31.2–43.9 months) were completed to evaluate procedure safety and durability of effect. Twenty-nine patients completed the 12-month and 36-month follow-up. All procedure-related adverse events occurred acutely, and no new events were observed during extended follow-up. At 36-months post-procedure, 57% (16/28) of baseline proton pump inhibitor (PPI)-dependent patients remained off daily PPI therapy. Treatment effect remained stable from 12- to 36-months, with 21/29 patients off daily PPI at 12 months compared to 17/29 patients at 36-months. Median GERD- Health Related Quality of Life (HRQL) scores remained significantly improved at 36 months versus baseline off-meds scores (8 versus 19, p < 0.001). In addition, the proportion of patients achieving ≥ 50% improvement in GERD-HRQL score was consistent from 12 months (59%) to 36 months (55%). Endoscopic full-thickness plication can reduce GERD symptoms and medication use for at least 3-years post-procedure. Treatment effect is stable from 1 to 3 years, and there are no long-term procedural adverse effects.
