Performance differences in laparoscopic surgical skills between true high-definition and three-chip CCD video systems

Abstract

All the participants preferred HD to SD. High definition significantly improved laparoscopic knot tying, which requires precise depth perception, proving that HD is more than just a pretty picture.

Comparison of two- and three-dimensional camera systems in laparoscopic performance: a novel 3D system with one camera

“…This result corresponds well with that of earlier studies, which showed that more movements were made to complete the tasks with the 2D system [9]. The fact that the error rate in the experienced group for task 1 had a tendency to increase on days 3 and 4 with the 2D system suggests that the participants in this group may have been driven by ''overconfidence,'' as noted previously by Hagiike et al [30]. However, there was no increase in the error rate with the 3D system.…”

“…We expect that the new 3D system with full highdefinition quality will provide better 3D perception and accuracy of laparoscopic performance in the near future [30]. Moreover, this novel one-camera system, using the effect of difference in density, can be modified to simulate multiple cameras and can be conjoined with the ''multiview 3D monitor systems.''…”

Neuromonitoring and video-assisted thyroidectomy: a prospective, randomized case-control evaluation

“…Certainly, the image magnification by the newly available high-definition endoscopes facilitates the identification of laryngeal nerves and parathyroid glands, providing visual discrimination among different tissues and depths [21][22][23].…”

Live augmented reality: a new visualization method for laparoscopic surgery using continuous volumetric computed tomography

“…Despite the introduction of modern high-definition laparoscopes, [15,16], their 3D visualization capability remains limited. Essentially a video imaging technique, they cannot show structures below the exposed surfaces.…”
