“…Thus, laparoscopic hysterectomy was less preferred over the years. Previous studies did not reveal any significant benefits of laparoscopic hysterectomy when compared with VH; [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] however, most of these studies are outdated and as the TLH experience increases among gynecologists, the superiority of VH when compared with laparoscopic hysterectomy is slowly changing over time. [26] In a small sample size study conducted in Germany in 2007, it was observed that TLH takes longer compared with VH; however, it reduces the postoperative hospitalization duration and analgesic usage.…”

“…[7,8] Nevertheless, laparoscopy is more difficult to learn and requires several psychomotor skills than open laparotomy, partly because the surgeons have to work in a three-dimensional (3D) space while being guided by two-dimensional (2D) images. [9,10] Therefore, surgeons lose perceptions of depth and spatial orientations and thus experience higher visual and cognitive loads. [11][12][13] To overcome few of the challenges associated with laparoscopy, 3D imaging was developed as an alternative to conventional 2D imaging.…”

“…[18,19] Because of the previously experienced side effects while using 3D vision systems, i.e., a degraded viewing condition from poor image resolution, the requirement to wear uncomfortable glasses, and the system's high costs compared with 2D equipment, this technology may be less preferred. [10][11][12][13][14][15][16][17][18][19][20] The most important limitation of conventional laparoscopy is the lack of a sense of depth because of a 2D flat view of the surgical field. Surgeons are forced to rely on monocular vision to understand the 3D sense of open surgery; however, even the most experienced surgeons may face difficulties while performing complex surgical tasks such as tissue dissection and suturing under only 2D visualization.…”

H ysterectomy is the oldest and commonly performed gynecological procedure. [1] It is the second most frequent gynecological operation after the cesarean section. [2,3] Importantly, uterus removal (excluding malignancies) is performed because of fibroids, bleeding irregularities, endometrial hyperplasia or cervical dysplasia, endometriosis, and prolapse. [1] Hysterectomies have been traditionally performed by laparotomy or vaginally. However, with recent advances in technology, laparoscopic equipment, and training, hysterectomies are being increasingly performed by laparoscopy.[4] As a consequence, a reduction of 38% in abdominal hysterectomy was observed in Western countries, with an increase in laparoscopic and vaginal surgeries. [2,5] With the worldwide increase of laparoscopic procedures, it is necessary for gynecological surgeons to publish and share their techniques, successes, complications, and recommendations to avoid possible adverse outcomes. [4] In cases whereObjectives: This study aimed to compare the outcomes of vaginal hysterectomy (VH) and two-and three-dimensional total laparoscopic hysterectomy (2D TLH, 3D TLH) in women with benign uterine diseases. Methods: A retrospective, randomized study was conducted at the Department of Obstetrics and Gynecology, Bagcilar Training and Research Hospital between 2010 and 2012. Overall, 99 women underwent VH, 68 underwent 2D TLH, and 41 underwent 3D TLH. Patients' ages, parities, uterine weights, pre-and postoperative hemoglobin (Hb) and hematocrit (Htc) values, operating times, complication rates, and hospitalization duration were compared. Results: A statistically significant difference was found among the groups in terms of patients' ages, parities, uterine weights, operating times, and hospitalization duration (p<0.05). Patients who underwent 3D TLH were younger and had lesser parities, greater uterine weights, and shorter operating times. The hospitalization duration was similar between the 2D and 3D TLH groups (average, 2 days; min, 1 day; and max, 8-10 days); however, it was shorter than the VH group (average, 3 days; min, 3 days; and max, 8 days). No statistically significant difference was observed among the groups in terms of the pre-and postoperative Hb/Htc values and complication rates (p>0.05). Conclusion: VH still remains the preferred procedure for patients with uterine prolapse and patients who require pelvic repair. 3D TLH offers quick operation with less complication rates and morbidity and reduces the hospitalization duration. Because of more favorable outcomes, we presume that 3D TLH may replace 2D TLH in the near future.

“…Some studies have found that 3DHD improves laparoscopic interventions with faster performance and higher precision without an increase in mental workload. 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.…”

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.

“…For 3D visualization, current publications almost exclusively demonstrate its superiority as compared to standard view. In a comprehensive evaluation, our group compared a state-ofthe-art HD monitor with a comparable 3D system and additionally to an autostereoscopic 3D display and an artificial display that offered 3D vision of a quality that was almost comparable to real view [49]. Interestingly, not only novices profited from stereoscopic view but also experts with an improvement in task performance of almost 20%.…”

Background: Optimal visualization of the operative field and methods that additionally provide supportive optical information form the basis for target-directed and successful surgery. This article strives to give an overview of current enhanced visualization techniques in visceral surgery and to highlight future developments. Methods: The article was written as a comprehensive review on this topic and is based on a MEDLINE search and ongoing research from our own group and from other working groups. Results: Various techniques for enhanced visualization are described comprising augmented reality, unspecific and targeted staining methods, and optical modalities such as narrow-band imaging. All facilitate our surgical performance; however, due to missing randomized controlled studies for most of the innovations reported on, the available evidence is low. Conclusion: Many new visualization technologies are emerging with the aim to improve our perception of the surgical field leading to less invasive, target-oriented, and elegant treatment forms that are of significant benefit to our patients.
