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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This early study tests whether a voice-controlled AI-assisted robotic system can safely help surgeons perform gallbladder removal. Ten adults with symptomatic gallstones or gallbladder polyps will undergo the procedure. The main goal is to see if the surgery can be completed without switching to a standard robot or open surgery, and without complications.

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 Cornerstone Robotics Sentire Surgical System (a voice-controlled robotic surgical device)
What this could lead to
If successful, this could pave the way for AI-assisted robotic surgery to become a standard, safer option for gallbladder removal and other procedures.
What could go wrong
This is a very early, small pilot study with only 10 participants, so results may not apply broadly. Technical failures or complications could still occur.

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

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 10 people

The number the study aims to enrol. It can still change while the study runs.

Started

Jun 2026

Expected to finish

Nov 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

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

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

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

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

Inclusion Criteria: * Age \>18 years, and * Body mass index \<35kg/m2, and * Scheduled for elective laparoscopic / robotic cholecystectomy for symptomatic gallstones or gallbladder polyp, and * American Society of Anesthesiologist (ASA) I-III Exclusion Criteria: * Contraindication to general anaesthesia * Severe concomitant illness that drastically shortens life expectancy or increases risk of therapeutic intervention * Past history of cholecystitis, liver abscess, Mirizzi syndrome * Contracted gallbladder or dilated common bile duct on pre-operative imaging * Known (Child's B or above) liver cirrhosis * Uncorrectable coagulopathy * Previous upper abdominal open surgery * Presence of another malignancy or distant metastasis * Emergency surgery * Vulnerable population (e.g. mentally incapacitated or pregnant persons)
