Outcome Measures

Primary Outcomes (1)

  • 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.

You may qualify if:

  • Pathologic reflux while off PPI based on Lyon criteria by either of the following:
  • Conclusive evidence for pathologic reflux defined as acid exposure time (AET) \> 6% (worst day) or LA grade C or D esophagitis.
  • Borderline evidence of pathologic reflux defined as presence of one of the following parameters: AET 4-6%, LA grade A or B.
  • Commitment to long-term study
  • Ability to give consent individually or by a legally authorized representative

You may not qualify if:

  • Hiatal hernia \> 5 cm (defined as maximum axial height from end of the esophagus to diaphragm by any study including upper endoscopy esophagram and or at time of surgery)
  • Evidence of clinically significant major esophageal motility disorder as determined by the site primary investigator
  • Pregnancy (in females) at time of procedure
  • Previous anti-reflux procedure
  • Subjects requiring mesh treatment at time of procedure
  • At the discretion of the site PI for subject safety
  • BMI \> 35 at time of surgery.
  • Prior gastric surgery that may affect ability to perform either procedure or affect normal gastric function (e.g. gastrectomy, gastric bypass, sleeve gastrectomy, pyloroplasty.
  • Severe gastroparesis

Masking Details
Measures will be taken to minimize or avoid bias in the study "masking/blinding procedures." Neither treatment groups will be advised as to which procedure (TIF or LNF) they will be receiving. Randomization assignment will be recorded in the EDC and subject tracking, but will not be recorded within the EMR to reduce clinical team exposure to their randomized status for follow-up care. Research teams will not be blinded to the randomization results.
