Live-streaming robotic liver resection for surgical education: is it safe? a multicenter matched cohort analysis.

Alessia Fassari et al. · Journal of robotic surgery · 2026

Background

Live-streaming surgery is increasingly used as an educational tool in the surgical community.

Methods

Forty-two consecutive patients who underwent robotic live-streaming liver resection (L-SS group) were matched 1:1 to patients who underwent not-live liver resection (not-L-SS group) during the same period, generating a matched cohort of 84 patients.

4.8%

Results

vs. 7.1%

serious problems after live-streamed surgery were similar to non-streamed surgery

More results

We assessed perioperative outcomes of robotic live-streaming liver resections compared with not-live streaming liver resections.

This multicenter retrospective matched cohort study reviewed 311 liver resections performed between October 2024 and December 2025 at three European HPB centers.

More results

Secondary endpoints included conversion to open surgery, intraoperative blood transfusion, postoperative bile leak, posthepatectomy liver failure, length of hospital stay, R1 resection rate, and 90-day mortality.

These findings were unchanged after excluding patients with a Pringle maneuver duration exceeding 60 min (sensitivity analysis).

Conclusion

Prospective studies should evaluate educational efficacy and trainee skill acquisition.
