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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 completed study tested whether artificial intelligence and fluorescence imaging could help less experienced surgeons identify the bile duct during laparoscopic gallbladder removal. Eight junior surgeons at different training levels watched videos of surgeries, with and without AI assistance, and tried to locate the bile duct. The goal was to see if this technology could improve surgical accuracy and safety during training.

What this could mean

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

What this could lead to
If successful, this approach could improve surgical training and reduce bile duct injuries during gallbladder removal.
What could go wrong
This was a very small study with only 8 participants, so results may not apply broadly. It focused on training, not patient outcomes.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Who can take part

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

Who is studied

Surgical trainees (postgraduate trainees, junior residents, and senior residents) recruited from a single tertiary academic medical center. Participants performed video-based assessments of indocyanine green-guided laparoscopic cholecystectomy recordings.

Ages

Children (under 18), adults (18 to 64) and older adults (65 and over)

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Postgraduate-year (PGY) trainees with fewer than 20 laparoscopic cholecystectomy (LC) cases. * Junior residents with 20-50 LC cases. * Senior residents with more than 50 LC cases. Exclusion Criteria: * Participants not available for the one-week washout and repeat assessment.
