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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers are reviewing medical records from 505 patients aged 18 to 80 who had their gallbladder removed with robotic assistance. The study compares short-term outcomes for operations done during regular daytime hours versus after hours, including nights, weekends, and holidays. They are looking at rates of conversion to open surgery, complications, readmissions, reoperations, operative time, imaging use, and hospital stay length.

What this could mean

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

Active substance
robotic-assisted cholecystectomy
What this could lead to
If after-hours robotic gallbladder surgery proves as safe as daytime surgery, hospitals could schedule these operations more flexibly without added risk.
What could go wrong
This is a retrospective chart review, so it can only show associations, not cause and effect. Differences between day and night cases may reflect patient mix or surgeon experience rather than timing itself.
