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 This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers compare two versions of sleeve gastrectomy in adults with obesity: one with an added step called omentopexy, where the stomach sleeve is attached to nearby fatty tissue, and one without. The main question is whether adding omentopexy lowers the number of people who develop new acid reflux after surgery, measured by a standard reflux questionnaire. Participants undergo one of the two procedures and complete follow-up visits to track reflux symptoms and other outcomes.

What this could mean

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

Active substance
omentopexy, a surgical step that attaches the stomach sleeve to nearby fatty tissue during weight-loss surgery
What this could lead to
If omentopexy helps, surgeons could add this step to sleeve gastrectomy to lower the chance of new acid reflux after weight-loss surgery.
What could go wrong
This is a single comparison at one hospital, so results may not apply everywhere. Omentopexy adds surgical time and could carry its own risks, and reflux may still occur.
