3D-HD Optic Systems Influence Surgical Performance
3D-HD Optic Systems Influence Surgical Performance
Randomized controlled trial in which two different laparoscopic systems: standard 2D and
 Olympus VISERA Elite II 3D will be compared in terms of laparoscopic skills, length of
 surgery, intraoperative complications and surgeon's fatigue in a group of senior surgeons and
 senior residents will be measured when performing laparoscopic Roux-en-Y gastric bypass.
The introduction of minimally invasive surgery has faced the surgeon with some difficulties
 that were not present in traditional open surgery. The foremost disadvantage of laparoscopy
 is the loss of depth perception in 2-dimensional (2D) vision while having to operate in a
 3-dimensional (3D) space.

 Minimally invasive surgery has become the standard approach for most of the abdominal
 surgical procedures. It is associated with less surgical trauma, faster recovery, shorter
 hospital stay and better cosmetic results. These advantages have led laparoscopic skills to
 become a basic competence for general surgery programs. Advanced laparoscopic surgery
 involves a long learning curve, including demanding minimally invasive skills such as
 intracorporeal suturing and knot tying.

 Video quality is critical for an accurate training. This is especially important for advanced
 laparoscopic skills training, where high-definition cameras are needed. HD imaging has been
 shown to provide subjectively improved image for visualization and to improve surgical task
 performance.

 Some authors have investigated the effect of laparoscopic 3-dimensional view, and have
 demonstrated an improvement in speed, efficiency, optics and handling as well as surgeon's
 subjective assessment. Moreover, 3D systems have been demonstrated to provide better optical
 visualization that allows simpler presentation of anatomical structures, which can decrease
 intraoperative errors and postoperative morbidity secondary to visual distortions and may
 reduce postoperative fatigue of the surgeon.

 The hypothesis of the study is that the length of surgery is reduced with the use of 3D
 laparoscopic systems compared with 2D laparoscopic systems, the reduction on the length of
 surgery will be higher on the training surgeons compared with the senior surgeons, and that
 the use of 3D laparoscopic systems reduces the postoperative fatigue of the surgeons.

 In this study a group of full-trained surgeons and of 4th and 5th year General Surgery
 Residents performing laparoscopic Roux-en-Y Gastric Bypass will be randomized into the use of
 2D standard laparoscopic optics or 3D laparoscopic optics.
