Comparative Assessment Between 3D and Conventional 2D Imaging Systems in Laparoscopic Practice

摘要

The objective of this study was to evaluate the effect of 3D imaging on laparoscopic suturing performance using a box trainer and during laparoscopic partial nephrectomy. Besides, the safety and usefulness of this technology in clinical practice were also subjectively evaluated. For the study in the training environment participated 30 surgeons and 13 surgeons in the study with the experimental animal model. Participants were organized in a random way into two groups, starting the trials with the 2D imaging system or with the 3D system. Three-dimensional imaging seemed to facilitate the performance of intracorporeal sutures in the box trainer setting. However, these improvements were not as clear during the partial nephrectomy. Surgeons stated that the 3D vision system helps improve depth perception during surgery and facilitates needle handling during intracorporeal suturing. However, they also indicated that its use can lead to the onset of visual discomfort or fatigue. Most of them would use again this vision system in surgical practice. Further studies are needed to more clearly determine the benefits of 3D over standard 2D imaging systems in laparoscopic practice.
