In this interesting study the authors looked at the efficacy of two-dimensional (2D) versus 3D high-definition endoscopes in novice users, not those already trained in 2D. Ninety-two medical students used 2D and 3D endoscopes to complete two validated tasks and participants were randomised as to which endoscopes they used first. Outcome measures included time taken and error rates as well as subjective data. They demonstrated that 3D was significantly faster and resulted in significantly fewer errors. In addition, 69% of participants preferred the 3D endoscopes. The study demonstrates that there may well be an inherent advantage in training and operating in 3D. For those of us trained in 2D, it may be time to upskill to 3D technology.
