Inclusion criteria

  1. 22-80 years of age
  2. Subjects have GERD with 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) and Hill grade III or IV
  3. Pathologic reflux while off PPI based on Lyon criteria by either of the following:

    3.1. Conclusive evidence for pathologic reflux defined as acid exposure time (AET) > 6% (worst day) or LA grade C or D esophagitis.

    3.2. Borderline evidence of pathologic reflux defined as presence of one of the following parameters: AET 4-6%, LA grade A or B.

  4. Commitment to long-term study
  5. Ability to give consent individually or by a legally authorized representative

Exclusion criteria

Exclusion Criteria:

  1. 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)
  2. Evidence of major esophageal motility disorder as determined by the site primary investigator
  3. Pregnancy (in females) at time of procedure
  4. Previous anti-reflux procedure
  5. Subjects requiring mesh treatment at time of procedure
  6. At the discretion of the site PI for subject safety
  7. > 35 at time of surgery.
  8. Prior gastric surgery that may affect ability to perform either procedure or affect normal gastric function (e.g. gastrectomy, gastric bypass, sleeve gastrectomy, pyloroplasty.
  9. Severe gastroparesis

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

What researchers measure

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.
