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
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 Results may not be published yet.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

Summary

This study tests an AI system that analyzes videos from gallbladder removal surgery (laparoscopic cholecystectomy) to label important structures in real time. The goal is to help surgeons avoid accidentally damaging the bile duct, a serious complication. Researchers will collect surgery videos from 200 adults and measure how accurately the AI identifies key anatomy.

What this could mean

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

Active substance
AI-assisted intraoperative anatomy analysis
What this could lead to
If successful, this AI tool could help surgeons avoid accidental bile duct injuries during gallbladder removal, making the procedure safer.
What could go wrong
This is an early-stage study focused on algorithm accuracy, not patient outcomes. The AI may not work well in all surgical settings or video qualities.
