What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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

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 Results may not be published yet.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

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.

Summary

This study tests a new version of sleeve gastrectomy (a weight loss surgery) that adds a Nissen fundoplication to reduce acid reflux. Researchers will compare 30-day complication rates between the new technique and standard sleeve gastrectomy in 100 adults with obesity. The goal is to see if the new approach is safer in the short term.

What this could mean

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

Active substance
Nissen sleeve gastrectomy (surgical procedure)
What this could lead to
If successful, this could show that the Nissen sleeve technique is as safe as standard sleeve gastrectomy, offering an option that may reduce acid reflux after surgery.
What could go wrong
This is a small, early-stage study (100 participants) comparing two surgical techniques. It only looks at complications within 30 days, so long-term safety and effectiveness are not yet known.
