ロボット仮想現実シミュレーターでのトレーニングは、術後のロボット手術スキルを向上させるか？系統的レビューとメタアナリシス

The effectiveness of virtual reality (VR) simulation training for improving robotic surgical skills is not firmly established. This systematic review and meta-analysis aimed to evaluate the impact of VR simulator training on surgeons' robotic surgical performance in the operating room (OR).

To synthesize evidence regarding the association between VR-based robotic surgery training and subsequent technical performance inside the OR.

A comprehensive literature search was conducted in PubMed, Scopus, Embase, and CINAHL databases, adhering to PRISMA 2020 guidelines.

Studies evaluating VR simulator training for robotic surgeons with subsequent performance assessment in the OR were included. Risk of bias assessment was performed using the Medical Education Research Study Quality Instrument and the modified Newcastle-Ottawa Scale for Education (NOS-E), along with funding source appraisal.

A total of 294 records were screened, resulting in 13 studies (281 participants) included in the systematic review, and 4 studies (72 participants) suitable for meta-analysis. Metaanalysis was conducted using a random-effects model to pool correlation coefficients between preand post-training performance.

Of the included studies, nine reported positive evidence, three found no evidence, and one found negative evidence regarding VR training's role. The meta-analysis of before-after studies revealed a significant positive correlation (r = 0.717, P < 0.05) between simulation performance and intraoperative outcomes.

The small number of studies included in the meta-analysis and methodological heterogeneity may limit generalisability of results.

VR simulator training is associated with improved robotic surgical performance in the OR. Incorporation of VR simulation into robotic surgical curricula is likely beneficial for skill acquisition and operative readiness.
