Multicenter Single-Blind RCT of CTIF Versus LNF For Treatment of GERD in Patients Requiring Hiatal Hernia Repair (CTIF)

Multicenter Single-Blind RCT of CTIF Versus LNF For Treatment of GERD in Patients Requiring Hiatal Hernia Repair Combined With Transoral Incisionless Fundoplication Versus Laparoscopic Nissen Fundoplication for Treatment of Gastroesophageal Reflux Disease in Patients Requiring Hiatal Hernia Repair

This single-blind randomized control study will follow 142 subjects across 7 sites randomized on a 1:1 ratio to compare treatment efficacy and safety between TIF and LNF in GERD patients with hiatal hernia undergoing hernia repair.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean difference in HRQL score ≤ 15%	Hypothesis: TIF is non-inferior to LNF as measured by quality of life at 6 months post-procedure using the Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) score. GERD-HRQL Scoring Total Score: Calculated by summing the individual scores to questions 1-15.; Greatest possible score (worst symptoms) = 75; Lowest possible score (no symptoms) = 0 Heartburn Score: Calculated by summing the individual scores to questions 1-6 .; Worst heartburn symptoms = 30; No heartburn symptoms = 0; Scores of ≤ 12 with each individual question not exceeding 2 indicate heartburn elimination. Regurgitation Score: Calculated by summing the individual scores to questions 10-15.; Worst regurgitation symptoms = 30; No regurgitation symptoms = 0; Scores of ≤ 12 with each individual question not exceeding 2 indicate regurgitation elimination.	6 months
