Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed envelope - only opened once surgery has commenced
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
200 envelopes will be prepared, containing equal numbers of each allocation. They will be shuffled, and then randomly selected from the pile of envelopes. There will be no stratification.
Masking / blinding
Blinded (masking used)

Summary
Brief summary
In a multicentre prospective double-blinded randomized trial, we will compare 3 laparoscopic methods for the repair of large hiatus hernia
a) Repair using either sutures alone
b) Repair with Biomesh (absorbable)
c) Repair with Timesh (non-absorbable).
to determine:
1) Short term and long term effectiveness of the hernia repair
2) Risk of postoperative side effects

This trial will test the hypothesis that there is no difference in the incidence of recurrent hiatus hernia for the 3 different techniques of repair of large hiatus hernia. The primary outcome will be the integrity of the hiatal repair assessed by barium meal X-ray. Secondary outcomes will include clinical recurrence of the hernia, the development of post-operative reflux, the development of post-operative side effects, and overall satisfaction with the surgical outcome.
