About this study
Official title: Robotic-Assisted Surgery With Versius in the NHS: Retrospective Comparative Performance Study Across Multiple Soft-Tissue Specialties
To generate robust, real-world comparative evidence on the short and long-term clinical outcomes following surgical intervention with Versius Robot-Assisted Surgery versus surgical standard of care across predefined soft-tissue index procedures in routine NHS practice.
- Conditions
- Robotic-assisted Soft-tissue Surgery
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Versius Robotic-Assisted Surgery | Patients undergoing soft-tissue surgical procedures using the Versius Surgical System | |
| Non-Versius Surgical Cohort | Patients undergoing comparable soft-tissue surgical procedures using non-Versius surgical approaches (conventional laparoscopic and open surgery). |
What is being measured
The primary outcome is the main question the study is designed to answer.
Procedure related complication rates
Rate of total procedure related complications within 30 days and up to 12 months following surgery
Measured: Within 30 days and 12 months after surgery
Secondary outcomes (5)
Length of hospital stay
Hospital stay in days from day of surgery until discharge
Measured: Up to post-surgical discharge, i.e. the date when patient is considered sufficiently recovered from surgery to leave hospital, expected to be at most up to 1 month after date of surgery, typically within a few days
Conversion rate
Proportion of surgical procedures requiring unplanned conversion to conventional laparoscopic or open surgery.
Measured: Up to completion of surgery
Operative time
Surgical time from skin incision to skin closure
Measured: Up to completion of surgery
Revision surgery rate
Proportion of participants requiring revision surgery within 12 months following the index surgical procedure. Revision surgery is defined as any subsequent surgical procedure required as a result of the index surgical procedure or the underlying condition for which the index surgical procedure was performed.
Measured: Within 12 months following surgery
Rate of pre-defined index procedure specific complications
Percentage of participants who experience one or more pre-defined procedure-specific complications related to the index surgical procedure
Measured: Within 30 days and 12 months after surgery

Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mark Slack (+44 7766 024389, mark.slack@cmrsurgical.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Procedure related complication rates (time frame: Within 30 days and 12 months after surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Oct 2026; AzTrials last refreshed its copy on 6 Nov 2026.
