Robot arms take on gallbladder surgery
NCT ID NCT07096856
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are studying how well the Versius Surgical System performs gallbladder removal surgery in adults. The study tracks how often the robotic procedure finishes without switching to another surgical method and whether serious complications occur within 30 days. Adults aged 22 and older who are eligible for minimally invasive gallbladder surgery can take part. The manufacturer of Versius, CMR Surgical Ltd, sponsors the study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Robotic-assisted gallbladder removal using the Versius Surgical System
- What this could lead to
- If it works well, this could support robotic surgery as a reliable option for gallbladder removal, potentially meaning smaller incisions and faster recovery for some patients.
- What could go wrong
- This is a post-market study tracking real-world use, not a head-to-head comparison, so it cannot prove Versius is better than other methods. Results may not apply to people with cancer, very high BMI, or those who cannot have general anesthesia.
