Study summary

Prospective randomized controlled trial to identify a sub-set of patients that do not benefit from the routine addition, and added morbidity, of a fundoplication during laparoscopic paraesophageal hernia repair.

Read the detailed description

Prospective Randomized Controlled Trial in which patients who meet criteria will be randomized to receive a concurrent fundoplication or no fundoplication at the time of paraesophageal hernia repair. Patients with known objective gastroesophageal reflux disease prior to surgery, those found to have a short esophagus in the operating room or defective gastroesophageal reflux barrier by intra-operative impedance planimetry measurements and/or endoscopic valve grade will be excluded.

    Procedure: Laparoscopic paraesophageal hernia repair without fundoplication

Interventions

  • ProcedureLaparoscopic paraesophageal hernia repair without fundoplication

    Patients undergoing laparoscopic paraesophageal hernia repair will be evaluated for risk of esophageal reflux using intra-operative impedance planimetry and endoscopic gastroesophageal valve grade. Patients deemed low risk for esophageal reflux will then be randomized to "partial fundoplication" or "no fundoplication".

06

What researchers measure

Primary outcomes

  1. Number of participants with GERD post-op

    Patients will undergo endoscopic evaluation and 48 hour pH testing to determine the incidence of objective GERD with and without fundoplication after PEH repair.

    Time frame: 12 months

Secondary outcomes

  1. Number of participants with hernia recurrence

    Routine upper GI contrast study and endoscopy will evaluate for hernia recurrence

    Time frame: 12 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2023 (actual). Primary completion is estimated for Feb 2025, 24 months after the start.

Of 33 interventional studies with no phase under Hernia, Hiatal, half reached primary completion within 54 months of starting (the median), counting those still running; a quarter within 22 and three quarters within 68. This study's planned 24 months is below that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 27, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
