Acclimatising with 3D virtual reality video improves simulator performance: initial findings of a randomised controlled feasibility trial.
Trial report in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionThe transition from traditional laparoscopy to robotic surgery marks a significant chage in surgical practice. An understated aspect of this transition may be the three dimensional (3D) view from the surgical console. This study hypothesises that acclimatisation with 3D virtual reality (VR) video may enhance robotic simulator performance in novice robotic surgeons.
methodsThis feasibility randomised controlled trial (RCT) involved 18 participants, randomly assigned to either a 3D VR video group or a 2D video group. The 3D group viewed a procedural video on a VR headset, while the 2D group watched the same video on a standard laptop screen. Participants then performed the initial 4 introductory robotic simulator exercises. Primary outcomes included automated performance metrics (APMs) including instrument path length, completion time, penalty scores, and overall performance score. Secondary outcomes were perceived mental workload using the NASA Task Load Index (NASA TLX) and cybersickness rates.
resultsThe 3D VR group demonstrated significantly better performance across all primary outcome measures. Mean overall performance scores for 3D VR was 52.75, compared to 29.78 for 2D (p < 0.01) Mean instrument path length for the 3D VR group was 305.09 cm, compared to 413.72 cm for the 2D group (p < 0.01) The 3D VR group incurred fewer penalty scores, with a mean of -8.16 compared to-23.99 for the 2D group (p = 0.03). 3 participants (21.4%) reported mild cybersickness symptoms with VR, which were transient. No significant differences were observed in perceived mental workload between the groups.
conclusionAcclimatisation with 3D VR video significantly enhances simulator performance among novice robotic surgeons, suggesting its potential integration into standard robotic surgery training protocols. Further studies with larger sample sizes and clinical settings are warranted to confirm these findings.
