What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a virtual reality simulator (VLaHHS) designed to train general surgery residents on laparoscopic hiatal hernia repair. Eight residents practiced on the simulator for up to 15 sessions over three weeks. Researchers measured their skill improvement and whether the training transferred to better performance in an actual procedure. The goal is to see if this simulator can effectively prepare surgeons before they operate on real patients.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Virtual Laparoscopic Hiatal Hernia Simulator (VLaHHS)
What this could lead to
If successful, this simulator could become a standard training tool to help surgeons learn hiatal hernia repair more effectively before operating on patients.
What could go wrong
This is a very small, early study with only 8 participants, so results may not apply broadly. The simulator may not improve real-world surgical skills as hoped.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

8 people

The number who actually took part.

Started

Apr 2025

Finished

Dec 2025

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.
