Background

The operational impact of transitioning from laparoscopic to robotic surgery is incompletely characterized, particularly regarding throughput and nonconsole operative time.

Methods

We analyzed 1664 consecutive cases performed by a single surgeon (2023-2026), comparing laparoscopic (n=632) and robotic eras (n=1032).

n = 632

Results

the non-surgical time in the operating room decreased with surgeon experience

More results

Weekly case volume increased from 9.54 to 11.36 (+19.1%), with stable OR days and increased cases per OR day (+17%).

Robotic cases had longer operative times (SG +14.0 min; RYGB +27.6 min, P<0.001).

The mean robotic OR overhead was ~19 minutes and consistent across independent data sources.

“

Conclusion

Transition to robotic surgery increased throughput despite longer operative times. Robotic OR overhead is substantial but declines with experience, suggesting recoverable efficiency gains over time.
