BN SO59 - Learning Curve for Robotic-Assisted Cholecystectomy

Abstract Background Assessment of learning curves following the introduction of robotic-assisted technology has shown that improvement in surgical outcomes can be seen with increasing robotic experience. Method All robotic-assisted cholecystectomies performed by a single consultant upper gastrointestinal surgeon as primary operator were analysed between 6/8/21 - 6/6/24 at a UK specialist centre using the Versius robotic system (CMR surgical). We recorded set up time during cases over this period. Results 38 robotic-assisted cholecystectomies were performed within the study period. In the first 10 cases, average set up time was 8 minutes and 18 seconds. In the second 10 cases this reduced to 5 minutes and 36 seconds. No further improvement was seen after case 20. Conclusion Our results demonstrate that set up time for robotic-assisted cholecystectomy improves over the first 20 cases. This data suggests 20 cases are adequate for acquiring the skillset required to set up the Versius robotic system efficiently in real life practice.
