Is this trial a fit for you?
✓Likely a good fit
Adult patients 22 years and older who are candidates for minimally invasive gallbladder surgery and can consent to participate.
✕Probably not a fit
Patients who have conditions making them unsuitable for robotic-assisted surgery or who do not meet consent requirements may not benefit.

What this trial studies
This post-market evaluation looks at the use of the Versius Surgical System for robotic-assisted cholecystectomy in adults. It collects data on technical success rates, 30-day safety outcomes, and patient recovery after surgery across several U.S. hospitals. Participants are adults 22 years or older undergoing minimally invasive gallbladder removal with Versius, with data gathered during the procedure and through a 30-day follow-up. The study aims to better understand device performance and real-world outcomes outside of controlled trials.
Why it matters
Potential benefit: If successful, the study could support broader use of the Versius system for gallbladder surgery and provide evidence on safety and recovery with robotic assistance.
How similar studies have gone: Prior studies of robotic cholecystectomy with similar systems have shown variable success; this study adds real-world pragmatic data for Versius.
