This Phase II, multicenter, single-arm clinical trial assessed the feasibility and safety of the MicroPort SA-1000 for single-port robotic cholecystectomy in 44 patients. All procedures were completed without conversion, with a median estimated blood loss of 10 mL and a median operating time of 88.43 minutes, indicating effective performance of the novel system.
Key findings
- All 44 patients completed the procedure without conversion.
- The median estimated blood loss was 10 mL, ranging from 5 to 200 mL.
- The median operating time was 88.43 minutes, with a standard deviation of 25.87 minutes.
- The median length of stay was 2.5 days, with a range of 1 to 7 days.
Why it matters
The study highlights the potential of single-port robotic cholecystectomy to enhance surgical outcomes through reduced trauma and effective triangulation, which may improve patient recovery times and overall surgical efficiency.
