“…Storz P. et al [25] concluded that the use of 3D might be of minor importance in simple tasks, but it can increased task efficiency when performing difficult surgical tasks. In accord with Navarra et al [20] we can explain our results on the basis of surgical technique for laparoscopic adrenalectomy, that do not request suturing, intracorporeal knotting or other difficult surgical tasks. Furthermore, experienced surgeons can overcome the limitations of 2D vision by memory of repetitive tactile information.…”

“…The variables analyzed for surgical outcome were: precision, definition of planes and depth perception. The variables for surgical strain were: wrist and hand strain, back strain, neck strain and eye strain [20]. In our University Hospital we also administered a modified questionnaire for measuring surgical outcome and personal interest of a total of 30 residents and medical students during live surgery sessions.…”

a b s t r a c tIntroduction: Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of twodimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Treedimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy. Methods: We report our experience with use of 3D vision system for laparoscopic adrenalectomy. Between January 2009 and March 2015 we performed a total of 52 laparoscopic adrenalectomies. In this case-control study we considered 13 laparoscopic adrenalectomies performed with three-dimensional (3D) vision system as case group. The last 26 procedures made with two-dimensional (2D) HD laparoscopic system represented the control group. We considered primary end-points: operative time, intraoperative complications and conversion rate. We evaluated also quality of depth perception and surgical strain. Results: Although the operative time for the entire surgical procedure was shorter in 3D group, there were no significant differences. The surgeon experienced better depth perception with 3D system and subjectively reported less strain using 3D vision system. Residents and medical students confirmed these data on surgical outcome. Conclusion: 3D system vision does not seem to influence the operative time of laparoscopic adrenalectomy performed by experienced surgeon because the surgical technique request simple tasks. We obtain the better visualization in depth perception with effect on surgical precision. Comparative studies are necessary to verify if 3D can reduce perioperative complication with similar operative time.

“…Romero-Loera et al . [11] reported a comparative study including only newcomers who have no experience in laparoscopy and concluded that 3D is superior than 2D with the higher percentages of tasks completion, less time in performing them, and a shorter learning curve involved in 3D.…”

Introduction:Conventional two-dimensional (2D) laparoscopy systems have the drawback of poor depth perception and spatial orientation. Three-dimensional (3D) laparoscopic systems have stereoscopic vision in which depth perception is achieved by different unique images received by each eye. We evaluated 3D laparoscopy in comparison with conventional 2D laparoscopy in urological procedures in a prospective randomized study.Materials and Methods:Over a 19 month study period, 108 patients scheduled to undergo various urological procedures were randomized to either conventional 2D or 3D laparoscopy (2D n = 53; 3D n = 55). A single senior surgeon performed all the surgeries. Parameters such as total operative time, dissection and suturing time, blood loss, hospital stay, complications (Clavien-Dindo), and visual analog scale (VAS) score for pain were assessed. The subjective assessment of the operating surgeon of superiority and inferiority of either technology on parameters defining surgical skills was recorded using a Likert scale.Results:The total operative time (P < 0.0003), blood loss (P < 0.028), dissection, suturing and stenting time (P < 0.0001), and the State-Trait Anxiety Inventory for Adults score (P < 0.0001) was significantly in favor of 3D laparoscopy.Conclusion:Our study showed significant advantages of the 3D system over 2D laparoscopy. These advantages include enhanced operative performance and greater surgeon comfort.

“…11,23 The 3DHD system has improved performance in complex surgeries by experienced surgeons. [24][25][26] In addition, other studies have demonstrated that the 3DHD system allows junior trainees to become proficient sooner, at least with respect to benchtop simulator tasks. 27,28 The ConMed 3DHD system has bi-channeled laparoscopes, creating a unique image for the right and left eyes.…”

Objectives: There are increased reports that kidney transplant can be performed by laparoscopic surgery. The further development of this technique could revolutionize human kidney transplant surgery. However, laparoscopic kidney transplant demands a high level of skill for vascular anastomoses. The emerging technology of the three-dimensional, highdefinition laparoscopic system may facilitate the application of this technique. Therefore, in this study, we evaluated this system in performing kidney transplant surgery versus the two-dimensional laparoscopic system. Materials and Methods: Four fresh-frozen human cadavers were used in this study, with 2 for the 3-dimensional and 2 for the 2-dimensional system. Kidneys were retrieved by using the retroperitoneoscopic technique for living donor nephrectomy from the same cadaver. The kidney graft was transplanted at the right iliac fossa using a laparo scopic technique by extraperitoneal approach. The procedure was recorded, and the vessel anastomotic time was analyzed. Results: Kidney transplant procedures were conducted successfully in the 3-dimensional, high-definition and the 2-dimensional groups. We recorded no significant differences in terms of vessel anastomotic time between the 2 groups. The total surgery time was shorter in the 3-dimensional, high-definition group than in the 2-dimensional group (P = .02). Conclusions:This pilot study reinforces that kidney transplant with either the 3-dimensional, highdefinition or 2-dimensional laparoscopy is feasible in a human cadaveric model. The operation was the same as open kidney transplant, but the procedure was performed by a laparoscopic approach with a smaller incision.
