“…Most of these studies have been conducted using an experimental surgical model [19,25]. A recent review reported a lower rate (63% of the trials) of errors with the use of 3D system [9,26]. 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.…”

“…Although 3D technology was introduced in the early 1990s its equipment is still not standard in hospital because of initial observation of side effects when using 3D vision systems, poor image resolution and more expensive cost [8]. In literature there are still few clinical studies on use of 3D with different results [9]. In this study we report our experience with use of 3D vision system for laparoscopic adrenalectomy.…”

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.

“…Sorensen et al [22] showed that 3D laparoscopic vision improves speed and reduces the number of performance mistakes when compared to 2D laparoscopic vision. In this manner, the efficacy and visual perception can be increased in fresh-frozen cadaveric model for laparoscopic training purpose by using 3D laparoscopic system.…”

Laparoscopic surgery is routinely used to treat many urological conditions and it is the gold standard treatment option for many surgeries such as radical nephrectomy. Due to the difficulty of learning, laparoscopic training should start outside the operating room. Although it is a very different model of laparoscopic training; the aim of this review is to show the value of human cadaveric model for laparoscopic training and present our experience in this area. Fresh frozen cadaveric model in laparoscopic training, dry lab, cadaveric model, animal models and computer based simulators are the most commonly used models for laparoscopic training. Cadaveric models mimic the live setting better than animal models. Also, it is the best way in demonstrating important anatomic landmarks like prostate, bladder, and pelvic lymph nodes templates. However, cadaveric training is expensive, and should be used by multiple disciplines for higher efficiency. The laparosopic cadaveric training starts with didactic lectures with introduction of pelvic surgical anatomy. It is followed by hands-on dissection. A typical pelvic dissection part can be completed in 6 hours. Surgical robot and some laparoscopy platforms are equipped with 3-D vision. In recent years, we have use the stereoscopic laparoscopy system for training purposes to show exact anatomic landmarks. Cadavers are removed from their containers 3 to 5 days prior to training session to allow enough time for thawing. Intracorporeal suturing is an important part of laparoscopic training. We believe that suturing must be practiced in the dry lab, which is significantly cheaper than cadaveric models. Cadaveric training model should focus on the anatomic dissection instead. In conclusion, fresh-frozen cadaveric sample is one of the best 3D simulation models for laparoscopic training purposes. Major aim of cadaveric training is not only mimicking the surgical technique but also teaching true anatomy. Lack of availability and higher financial cost are the two setbacks for the use of cadavers. Surgeon should learn basic laparoscopic skills with box trainers prior to cadaveric skill training.

“…A review of the literature has shown that 3D laparoscopy seems to improve the speed and reduce the performance errors compared with 2D laparoscopy. 11 Aykan and associates have shown that 3D laparoscopic radical prostatectomy is associated with shorter operation time, less blood loss, and higher early continence rates than conventional 2D laparoscopy. 12 However, an early randomized clinical trial on laparoscopic cholecystectomy did not show any evidence that 3D was superior to 2D.…”

“…13 It is still unclear whether 3D laparoscopic equipment can improve the proficiency in performing complex laparoscopic surgeries as most of these studies have been conducted in simulated settings using tasks whose face validity might be questioned compared with human organ transplant. 11 Therefore, the aim of this study was to evaluate a 3D, high-definition (3DHD) system versus a 2D laparoscopic system in performing a complex procedure of kidney transplant with a human cadaveric training model.…”

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.

Three-dimensional versus two-dimensional vision in laparoscopy: a systematic review

Abstract: Overall, 3D laparoscopy appears to improve speed and reduce the number of performance errors when compared to 2D laparoscopy. Most studies to date assessed 3D laparoscopy in simulated settings, and the impact of 3D laparoscopy on clinical outcomes has yet to be examined.
