Obes Surg 2024; 34:2177-2185. [PMID: 38630144 PMCID: PMC11127895 DOI: 10.1007/s11695-024-07222-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2024] [Revised: 03/30/2024] [Accepted: 04/10/2024] [Indexed: 05/27/2024]
Abstract
Three-dimensional (3D) laparoscopy has several advantages in gastrointestinal surgery. This systematic review determined whether similar benefits exist for bariatric surgical procedures by systematically searching the MEDLINE, Embase, and Scopus databases. Six studies including 629 patients who underwent 2D (386) and 3D (243) laparoscopic bariatric surgeries were selected. Operative time was significantly shorter in patients undergoing 3D laparoscopic gastric bypass (pooled standardized mean difference [SMD] 1.19, 95% confidence interval [CI] 2.22-0.15). Similarly, a shorter hospital stay was detected both during sleeve gastrectomy (SMD 0.42, 95% CI 0.70-0.13) and gastric bypass (SMD 0.39, 95% CI 0.64-0.14) with 3D laparoscopy. The study showed the potential benefit of 3D imaging in preventing intra- and postoperative complications. Despite the limited evidence, surgeons may benefit from 3D laparoscopy during bariatric surgery.

Arch Gynecol Obstet 2024; 309:1027-1033. [PMID: 38184803 DOI: 10.1007/s00404-023-07335-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2023] [Accepted: 12/05/2023] [Indexed: 01/08/2024]
Abstract
PURPOSE 2D/Ultra HD and 3D/Full HD imaging systems can provide surgeons with more accurate and detailed views of the surgical site. We aimed to compare the effects of 2D/Ultra HD and 3D/Full HD laparoscopy systems on laparoscopic suturing skills during total laparoscopic hysterectomy. METHODS In this prospective cohort study, patients were recruited from a tertiary hospital, and demographic data and surgical data were recorded. The primary outcome measures were the durations of the total operation and vaginal cuff closure. Secondary outcome measures were colpotomy duration, total number of sutures placed, duration of first, second, third and fourth sutures, mean suturing duration, total operation duration, the surgeon's perception of difficulty during the vaginal cuff suturing and complications. RESULTS The 3D/Full HD (n = 39) and 2D/Ultra HD (n = 42) groups were compared in terms of age, BMI, number of previous abdominal surgeries, number of previous cesarean sections, and type of delivery were examined. Both groups were considered homogeneous. The 3D/Full HD group was found to be superior in terms of colpotomy duration, duration of the first, second, and third suture, mean suturing duration, vaginal cuff closure duration, and difficulty of use compared to 2D/Ultra HD group (p < 0.05 for all). CONCLUSION In conclusion, the use of 3D/Full HD laparoscopy systems can lead to improved surgical outcomes in terms of colpotomy duration, duration of the first, second, and third suture, mean suturing duration, vaginal cuff closure duration, and difficulty of use compared to 2D/Ultra HD systems.

Abstract
BACKGROUND AND AIMS Recent studies on endoscopic submucosal dissection have aimed to reduce the difficulty of the procedure by using multi-degrees-of-freedom articulating devices. In this study, we evaluated the usefulness of adding three-dimensional (3D) video imaging into simulated endoscopic submucosal dissection tasks using multi-degrees-of-freedom devices. METHODS We designed an endoscopic platform with a 3D camera and two multi-degrees-of-freedom devices. Four ex vivo bench tasks were created, and a crossover study comparing 2D and 3D conditions was conducted on 15 volunteers. In each task, performance such as procedure time and accuracy were objectively evaluated. Additionally, a comprehensive visual analogue scale questionnaire was conducted. RESULTS In the tasks simulating submucosal flap grasping, marking, and full-area incision, the use of 3D imaging significantly improved the speed and accuracy of the multi-degrees-of-freedom device manipulation (p < .01). No significant differences were observed in the task that simulated the dissection procedure. Furthermore, it appears that the accuracy of recognizing curved surfaces may be reduced in the 3D environment. Operators reported subjective increases in recognizability and operability with the 3D camera, along with an increase in asthenopia (p < .01). CONCLUSIONS 3D vision improves the technical accuracy of certain simulated multi-degrees-of-freedom endoscopic submucosal dissection tasks and subjectively improved operating conditions, at the cost of increased eye strain.

Abstract
3D imaging technology is becoming more prominent every day. However, more validation is needed to understand the actual benefit of 3D versus conventional 2D vision. This work quantitatively investigates whether experts benefit from 3D vision during minimally invasive fetoscopic spina bifida (fSB) repair. A superiority study was designed involving one expert team ([Formula: see text] procedures prior) who performed six 2D and six 3D fSB repair simulations in a high-fidelity animal training model, using 3-port access. The 6D motion of the instruments was recorded. Among the motion metrics are total path length, smoothness, maximum speed, the modified Spectral Arc Length (SPARC), and Log Dimensionless Jerk (LDLJ). The primary clinical outcome is operation time (power 90%, 5% significance) using Sealed Envelope Ltd. 2012. Secondary clinical outcomes are water tightness of the repair, CO[Formula: see text] insufflation volume, and OSATS score. Findings show that total path length and LDLJ are considerably different. Operation time during 3D vision was found to be significantly shorter compared to 2D vision ([Formula: see text] vs. [Formula: see text] min; p [Formula: see text] 0.026). These results suggest enhanced performance with 3D vision during interrupted suturing in fetoscopic SBA repair. To confirm these results, a larger-scale follow-up study involving multiple experts and novice surgeons is recommended.

Abstract
OBJECTIVES This study aimed to assess the superiority of 3D flexible thoracoscope against 2D thoracoscope for lymph node dissection (LND) and prognosis for prone-position thoracoscopic esophagectomy (TE) in esophageal cancer. METHODS Three hundred and sixty-seven esophageal cancer patients who underwent prone-position TE with 3-field LND between 2009 and 2018 were evaluated. 2D and 3D thoracoscope was used in 182 (2D group) and 185 cases (3D group), respectively. Short-term surgical outcomes, numbers of retrieved mediastinal lymph node (LN), and rates of LN recurrence were compared. Risk factors for mediastinal LN recurrence and long-time prognosis were also evaluated. RESULTS No differences in postoperative complications were observed between the groups. The numbers of retrieved mediastinal LN were significantly higher, and the rates of LN recurrence were significantly lower in the 3D group compared to 2D group. Use of 2D thoracoscope was a significant independent factor of middle mediastinal LN recurrence by multivariable analysis. Survival was compared by cox regression analysis, and the 3D group had a significantly better prognosis than the 2D group. CONCLUSIONS Prone position TE using 3D thoracoscope may improve the accuracy of mediastinal LND and prognosis without increasing postoperative complications for esophageal cancer.

Laparoscopic surgery in 3D improves results and surgeon convenience in sleeve gastrectomy for morbid obesity. Langenbecks Arch Surg 2022; 407:3333-3340. [PMID: 36180641 DOI: 10.1007/s00423-022-02681-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Accepted: 09/12/2022] [Indexed: 10/07/2022]
Abstract
PURPOSE Advanced laparoscopic procedures are still challenging. One critical issue is the lack of stereoscopic vision. The aim of this surgical study is to evaluate whether 3D vision offers any advantages for surgical performance over 2D vision during sleeve gastrectomy for morbid obesity using a laparoscopic system that allows changing between 2D and 3D optics. METHODS A total of 78 patients were analyzed, with 37 in the 2D group and 41 in the 3D group. Performance time, hospital stay, complications, and early outcomes were collected. To assess the quality of the 2D and 3D techniques, visual analog scales from 0 to 10 were designed, and image quality, depth of field, precision in performing tasks, and general ergonomics were measured. RESULTS According to the vision system used, the mean duration of surgery was 85 ± 16.8 min for patients operated on with the 2D system and 69 ± 16.9 min for those operated on with the 3D system. There were no significant differences between the overall percentages of complications according to the type of vision used. However, postoperative complications were more severe in the 2D laparoscopy group. The average length of stay was shorter for patients in the 3D group. Regarding the differences perceived by the surgeon, the depth of field and the precision of tasks were better in the 3D vision group. CONCLUSION The 3D system provided greater depth perception and precision in more complex tasks, enabling safer surgery. This led to a reduction in the operative time and hospital stay. Moreover, the severity of complications was less.

Abstract
Background Whether the utilization of preoperative three-dimensional (3D) lung simulation can improve the outcomes of segmentectomy for lung cancer (LC) is still controversial. Our meta-analysis was performed to compare preoperative 3D lung simulation with non-3D procedures in terms of perioperative outcomes. Methods Seven databases (Embase, Ovid Medline, ScienceDirect, PubMed, Web of Science, Cochrane Library, and Scopus) were searched for eligible articles. Intraoperative outcomes (conversion, operative time, etc.), postoperative indicators (postoperative hospital stay, total number of complications, etc.) and postoperative complications were endpoints. Results After applying predefined inclusion criteria, we included 8 studies and 989 patients (3D group: 552 patients; non-3D group: 437 patients) in our meta-analysis. The results of the meta-analysis showed that preoperative 3D lung simulation could significantly decrease the blood loss (mean difference [MD]: -16.21 [-24.95 to -7.47]ml, p = 0.0003), operative time (MD: -13.03 [-25.56 to -0.50]ml, p = 0.04), conversion rate (conversion from segmentectomy to thoracotomy or lobectomy) (MD: 0.12 [0.03-0.48], p = 0.003), postoperative hospital stay (MD: -0.25 [-0.46 to 0.04]days, p = 0.02) and total number of complications (MD: 0.59 [0.43-0.82], p = 0.001) compared with non-3D procedures. The number of resected lymph nodes (LNs), postoperative drainage time, postoperative forced expiratory volume in the first second (postoperative FEV1) and postoperative drainage volume were similar in the two groups. Arrhythmia (5.30%), pulmonary air leakage (2.72%), atrial fibrillation (2.20%), pulmonary infection (2.04%), and pneumonia (1.73%) were the top 5 postoperative complications in the 3D group. Conclusions Preoperative 3D lung simulation was better than non-3D procedures in segmentectomy for LC, with better intraoperative and postoperative outcomes. However, our results should be confirmed in larger prospective randomized controlled trials. Systematic Review Registration PROSPERO, identifier: CRD42021275020.

Abstract
Background Video-assisted thoracic surgery sleeve resection with bronchial anastomosis or bronchoplasty is a technically demanding procedure. Three-dimensional endoscopic surgery has been reported to be helpful in decreasing operation time and improving spatial perception with less surgical errors, but there have been rare reports about relatively difficult thoracoscopic procedures utilizing 3D thoracoscope. We performed this study to evaluate early clinical outcomes of thoracoscopic sleeve resection and bronchoplasty utilizing 3D thoracoscope.
Methods Data from a total of 36 patients who underwent thoracoscopic sleeve lobectomy or bronchoplasty at our institution from December 2015 to October 2017 were retrospectively reviewed. Three-port approach with one utility incision was used with a 10 mm, 30° three-dimensional thoracoscope. Twenty-three patients (81%) were male, and mean age was 65.9 ± 9.4 years. Fourteen patients (38.9%) underwent sleeve resection with bronchial anastomosis, 22 (61.1%) underwent wedge or simple bronchoplasty, and one patient received concomitant PA procedure. Bronchial anastomosis sites were not covered with viable tissue flaps.
Results There was no (0%) suture needle injury from spatial misperception during bronchoplasty or sleeve anastomosis. There was no (0%) operative mortality. The pathologic report revealed squamous cell carcinoma (63.9%), adenocarcinoma (19.4%), carcinoid (6.9%), adenosquamous carcinoma (3.4%), and sarcomatoid carcinoma (2.8%). One (2.8%) late mortality was due to systemic recurrence of sarcomatoid carcinoma. There was no (0.0%) anastomotic failure. The mean number of dissected lymph nodes were 27.4 ± 13.2, and mean operation time was 216.8 ± 60.0 min. Median postoperative 24-h drain amount was 315 mL. Median chest tube days and hospital days were 4 and 6, respectively. Two patients (5.6%) had complications greater than Clavien-Dindo grade II—one case of ARDS, and the other case of a delayed bronchopleural fistula. Conclusions Thoracoscopic sleeve resection and bronchoplasty utilizing HD 3D thoracoscope is a safe and effective procedure with excellent early clinical outcomes. Further investigation for long-term outcomes will be needed.

Abstract
Heads-up three-dimensional (3D) surgical visualization systems allow ophthalmic surgeons to replace surgical microscope eyepieces with high-resolution stereoscopic cameras transmitting an image to a screen. We investigated the effectiveness and safety of the heads-up NGENUITY 3D Visualization System in a retrospective evaluation of 241 consecutive vitreoretinal surgeries performed by the same surgeon using conventional microscopy (CM group) over a 1-year period versus the NGENUITY System (3D group) over a consecutive 1-year period. We included for study vitreoretinal surgeries for treatment of retinal detachment (RD) (98 surgeries), macular hole (MH) (48 surgeries), or epiretinal membrane (ERM) (95 surgeries). A total of 138 and 103 eyes were divided into 3D and CM groups, respectively. We found no differences in 3-month postoperative rates of recurrence of RD (10% versus 18%, p = 0.42), MH closure (82% versus 88%, p = 0.69), or decrease in central macular thickness of ERMs (134 ± 188 µm versus 115 ± 105 µm, p = 0.57) between the 3D and CM groups, respectively. Surgery durations and visual prognosis were also similar between both groups. We consolidate that the NGENUITY System is comparable in terms of visual and anatomical outcomes, giving it perspectives for integration into future robotized intervention.

Comparison of two- and three-dimensional endoscopic visualization for fetal myelomeningocele repair: a pilot study using a fetoscopic surgical simulator. Childs Nerv Syst 2021; 37:1613-1621. [PMID: 33392653 DOI: 10.1007/s00381-020-04999-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Accepted: 12/03/2020] [Indexed: 11/28/2022]
Abstract
INTRODUCTION The objective of this study was to evaluate the utility of three-dimensional (3D) versus conventional two-dimensional (2D) endoscopy for fetal myelomeningocele repair using a low-fidelity fetoscopic surgical simulator. METHODS A low-fidelity fetoscopic box trainer was developed for surgical simulation of myelomeningocele repair. Participants with varying surgical experience were recruited and completed three essential tasks (cutting skin, dural patch placement, and suturing skin) using both 2D and 3D endoscopic visualization. Participants were randomized to begin all tasks in either 2D or 3D. Time to completion was measured for each task, and each participant subsequently completed the NASA Load Index test and a questionnaire evaluating their experience. RESULTS Sixteen participants completed the study tasks using both 2D and 3D endoscopes in the simulator. While the mean performance time across all tasks was shorter with 3D versus 2D endoscopy (cutting skin, 47 vs. 54 seconds; dural patch placement, 38 vs. 52 seconds; and suturing skin, 424 vs. 499 seconds), the results did not reach statistical significance. When comparing times to completion of each of the three tasks between levels of expertise, participants in the expert category were faster when suturing skin on the 2D modality (P = 0.047). Under 3D visualization, experts were faster at cutting the skin (P = 0.008). When comparing experiences using the NASA-TLX test, participants felt that their performance was better using 3D over the 2D system (P = 0.045). Overall, 13 of 16 (81.3%) participants preferred 3D over 2D visualization. CONCLUSIONS Three-dimensional endoscopes could potentially be used in the near future for relative improvement in visualization and possibly performance during complex fetoscopic procedures such as prenatal repair of myelomeningocele defects. Further studies utilizing 3D scopes for other related procedures may potentially support clinical implementation of this technology in fetal surgery and also prove to be a useful tool in surgical training.

A Novel Low-Cost Exoscopy Station for Training Neurosurgeons and Neurosurgery Trainees. World Neurosurg 2021; 150:31-37. [PMID: 33722725 DOI: 10.1016/j.wneu.2021.02.126] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 02/28/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND The loss of stereopsis and the need for markedly enhanced hand-eye coordination are obstacles to overcome when performing exoscopic procedures, but both should improve with training. Our objectives were to describe an exoscopy training station and to compare time and performance of a given microsurgical technique among neurosurgery residents and junior neurosurgeons. METHODS We designed a low-cost exoscopy training station featuring a notebook computer, a webcam, and a light-emitting diode source. Surgeons and surgical trainees with no experience in exoscopy were enrolled and divided into 2 groups (trainees and controls). Performance and time in suture placement were evaluated by a skilled observer in both groups at baseline and 3 days later. Between evaluations, trainees completed an exoscopy training module. RESULTS There were 22 participants divided equally into 2 groups. At baseline, trainees had a greater percentage of proper sutures than controls (58% vs. 35%), but they were also slower (32 minutes vs. 25 minutes). On final evaluation, not only were trainees approximately 14 minutes faster than at baseline (P = 0,03), but also their successful suture rate had increased by 18% (final rate 76%, P = 0.02). Moreover, controls were faster compared with baseline by 6 minutes (P = 0.003), but their percentage of successful sutures did not increase (final rate 38%, P = 0.49). The change from baseline to final evaluation favored trainees for both outcomes (P = 0.03 and P = 0.02). CONCLUSIONS Using the exoscopy training station, the trainees were able to improve their time and performance of exoscopy compared with the controls.

Abstract
PURPOSE There are currently no reports on the application of three-dimensional (3D) vision to single-incision laparoscopic surgery. This study compared 3D vision to the previous two-dimensional (2D) system in single-incision laparoscopic distal gastrectomy (SIDG). METHODS Medical charts of 179 gastric cancer patients who underwent SIDG from February 2014 to December 2017 were retrospectively reviewed. Patients were grouped into either a 2D group or 3D group depending on the type of camera that was used. All operations were performed using a flexible camera (Olympus, Japan). Operative data and postoperative outcome were analyzed. RESULTS There were 90 patients in the 2D group and 89 patients in the 3D group. No differences were found in terms of the age, body mass index, staging, and other demographics of the patients. Operative time was significantly faster in the 3D group (115.6 ± 34.0 vs. 129.4 ± 38.5 min, p = 0.012), and estimated blood loss (EBL) was less in the 3D group (20.7 ± 30.0 vs. 35.1 ± 56.0 ml, p = 0.034). Patients in the 3D group were able to start a small fluid diet earlier (2.5, range 1-6 vs. 3.0, range 2-8 postoperative days, p = 0.006) and were discharged faster (5.4, range 3-12 vs. 6.2, range 4-24 postoperative days, p = 0.024). There was no statistical difference between early and late complications. CONCLUSION The use of the 3D camera shortened operative time with possible clinical benefits for patients undergoing SIDG.

Abstract
INTRODUCTION Laparoscopic pancreatic reconstruction is a challenging procedure and is considered the Achilles' heel of laparoscopic pancreatectomy. Multiple techniques of laparoscopic pancreatic reconstruction have been reported, but the optimal technique remains unclear. AREAS COVERED This paper provides a brief introduction to the developmental status and major related complications of laparoscopic pancreatic reconstruction. We reviewed all published literature on the technology of laparoscopic pancreatic reconstruction within the last 5 years and herein discuss the advantages and disadvantages of different reconstruction methods. We also discuss several details of different reconstruction techniques in terms of their significance to the operation and complications. EXPERT OPINION No individual method of laparoscopic pancreatic reconstruction is considered optimal for all conditions. The reconstruction strategy should be based on the surgeon's proficiency with laparoscopic technology and the patient's individual risk factors. Personalized methods of pancreatic reconstruction may more effectively reduce morbidity and mortality.

Abstract
Background: Extra-corporeal video telescope operating monitor system provides a necessary instrument to perform high-precision neurosurgical procedures that could substitute or supplement the traditional surgical microscope. The present study was designed to evaluate a compact high-definition two-dimensional exoscope system for assisting in surgical removal of large vestibular schwannoma (VS), as an alternative to a binocular surgical microscope. Methods: Patients with Koos grade 3 and grade 4 VS undergoing surgery were enrolled in this prospective cohort study between January 2013 and June 2018. The demographics and tumor characteristics (size, Koos grade, composition [cystic or solid mass]) were matched between the two groups of patients. The following outcome measurements were compared between the two groups: duration of surgery, volume of blood loss, extent of tumor resection, number of operating field adjustments, pre- and post-operative facial and cochlear nerve function evaluated at 3 months post-surgery, complications and surgeons’ comfortability. Results: A total of 81 patients received tumor resection through the retrosigmoid approach under either an exoscope (cases, n = 39) or a surgical microscope (control, n = 42). Patients in the two groups had comparable tumor location (P = 0.439), Koos grading (P = 0.867), and composition (P = 0.891). While no significant differences in the duration of surgery (P = 0.172), extent of tumor resection (P = 0.858), facial function (P = 0.838), and hearing ability (P = 1.000), patients operated on under an exoscope had less blood loss (P = 0.036) and a fewer field adjustments (P < 0.001). Both primary and assistant surgeons reported a high level of comfort operating under the exoscope (P = 0.001 and P < 0.001, respectively). Conclusions: The compact high-definition two-dimensional exoscope system provides a safe and efficient means to assist in removing large VSs, as compared to a surgical microscope. After the acquaintance with a visual perception through a dynamic hint and stereoscopically viewing corresponding to the motion parallax, the exoscope system provided a comfortable, high-resolution visualization without compromising operational efficiency and patient safety.

Abstract
BACKGROUND Due to the technological advance in resolution and stereoscopic depth, the 3-dimensional (3D) laparoscopic system has been widely used in real surgery. However, there have been few studies to confirm the clinical usefulness of the 3D laparoscopic distal gastrectomy (LDG). This study aimed to compare perioperative outcomes between the 2-dimensional (2D) and 3D LDG for gastric cancer patients. METHODS This was a prospective, randomized controlled, single-center, and superiority trial. This study was carried in Seoul National University Bundang Hospital. Patients with histologically confirmed gastric adenocarcinoma which could be radically resected by LDG were randomly assigned (1:1) to the 2D or 3D group. From October 2016 to August 2018, 84 patients were included in this study and randomly assigned into the 2D group (44 patients) or the 3D group (40 patients). A total of 5 patients were excluded; 3 in the 2D group and 2 were in the 3D group. Consequently, the data from 79 patients were analyzed (2D: 41 cases; 3D: 38 cases). For the LDG procedure, 3D and 2D camera and display system were applied according to the assigned group. The primary end point was the duration of total laparoscopic operation time. Secondary end points included the amount of intraoperative blood loss (IBL), the number of harvested lymph nodes, postoperative complications and open conversion rate. RESULTS There were no differences between 2 and 3D groups with respect to clinicopathologic characteristics. The total operation time in 3D groups was significantly shorter than 2D group (122 [106.5-161] versus 101 [77.75-125.5] minutes; P = 0.001). The postoperative complication rates in the 3D groups was significantly lower than 2D group (24.4% versus 7.9%, respectively; P = 0.045). CONCLUSION 3D LDG shorten the operation time compared with 2D LDG in gastric cancer patients. And 3D laparoscopy provided the benefit of less postoperative complications.

Abstract
BACKGROUND Three-dimensional (3d) laparoscopy has been introduced to enhance depth perception and facilitate surgical operations. The aim of this study was to compare cognitive load during 3d and 2d laparoscopic procedures. METHODS Two subjective questionnaires (the Simulator Sickness Questionnaire and the NASA task load index) were used to prospectively collect data regarding cognitive load in surgeons performing 2d and 3d laparoscopic colorectal resections. Moreover, the perioperative results of 3d and 2d laparoscopic operations were analyzed. RESULTS A total of 313 patients were included: 82 in the 2d group and 231 in the 3d group. The NASA TLX results did not reveal significantly major cognitive load differences in the 3d group compared with the 2d group; the SSQ results were better in the 3d group than in the 2d group in terms of general discomfort, whereas difficulty concentrating, difficulty focusing, and fatigue were more frequent in 3d operations than in 2d operations (p = 0.001-0.038). The results of age, sex, and ASA score were comparable between the two groups (p = 0.299-0.374). The median operative time showed no statistically significant difference between the 3d and 2d groups (median, IQR, 2d 150 min [120-180]-3d 160 min [130-190] p = 0.611). There was no statistically significant difference in the risk of severe complications between patients in the 3d group and in the 2d group (2d 7 [8.54%] vs 3d 21 [9.1%], p = 0.271). The median hospitalization time and the reoperation rate showed no difference between the 2d and 3d operations (p = 0.417-0.843). CONCLUSION The NASA TLX did not reveal a significant difference in cognitive load between the 2d and 3d groups, whereas data reported by the SSQ showed a mild risk of cognitive load in the 3d group. Furthermore, 3d laparoscopic surgery revealed the same postoperative results as 2d standard laparoscopy.

Abstract
In this study, a controllable tactile device capable of realizing repulsive forces from soft human tissues was proposed, and its effectiveness was verified through experimental tests. The device was fabricated using both porous polyurethane foam (PPF) and smart magnetorheological fluid (MRF). As a first step, the microstructural behavior of MRF particle chains that depended on the magnetic field was examined via scanning electron microscopy (SEM). The test samples were then fabricated after analyzing the magnetic field distribution, which was crucial for the formation of the particle chains under the squeeze mode operation. In the fabrication of the samples, MRF was immersed into the porous polyurethane foam and encapsulated by adhesive tape to avoid leakage. To verify the effectiveness of the proposed tactile device for appropriate stiffness of soft human tissues such as liver, the repulsive force and relaxation stress were measured and discussed as a function of the magnetic field intensity. In addition, the effectiveness and practical applicability of the proposed tactile device have been validated through the psychophysical test.

Abstract
IMPORTANCE Errors and adverse events occur frequently in health care. Three-dimensional (3-D) laparoscopic systems claim to provide more realistic depth perception and better spatial orientation compared with their 2-D counterparts. OBJECTIVE To compare the association of 3-D vs 2-D systems with technical performance during laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures using a multiport intraoperative data capture system. DESIGN, SETTING, AND PARTICIPANTS This cohort study was performed between May and December 2018, with a total of 50 LRYGB procedures performed in an academic tertiary care center; recordings of the operations were evaluated with a 30-day follow-up. All procedures were performed by the same surgical team. EXPOSURE Surgical teams used 2-D or 3-D laparoscopic systems. MAIN OUTCOMES AND MEASURES Technical performance was evaluated using the Objective Structured Assessment of Technical Skill and surgical errors and events using the Generic Error Rating Tool. RESULTS Of the 50 patients who underwent LRYGB procedures, 42 (86%) were women, with a median (interquartile range) age of 42 (35-47) years and a median (interquartile range) body mass index of 46 (42-48), with no significant demographic differences between the groups whose operations were performed using the 2-D and 3-D systems. The mean (SD) number of errors per case was significantly lower in procedures using the 3-D laparoscopic system than in those using the 2-D system (17 [6] vs 33 [2]; P < .001). The mean (SD) number of error-related events was significantly lower in procedures using the 3-D system than in those using the 2-D system (6 [2] vs 11 [4]; P < .001). Mean (SD) Objective Structured Assessment of Technical Skill scores were significantly higher when the 3-D system was used than when the 2-D system was used (28 [4] vs 22 [3]; P < .001). CONCLUSIONS AND RELEVANCE In this limited sample of LRYGB procedures, the use of a 3-D laparoscopic system was associated with a statistically significant reduction in errors and events as well as higher Objective Structured Assessment of Technical Skill scores compared with 2-D systems.

Abstract
Backgrounds/Aims Laparoscopic cholecystectomy (LC) has become widely used and preferred standard treatment for gallbladder (GB) disease in many countries. In this study, we aimed to compare the overall clinical outcomes of 3-dimensional (3D) LC system with those of the 2D LC method. Methods We retrospectively analyzed patients who underwent LC for acute cholecystitis between January 2010 and March 2019 at the National Medical Center in Korea. We entered them into 3D LC (group A) and 2D LC (group B) groups. We used Olympus CLV-190 laparoscopic device with dual lenses, capable of displaying both 3D and 2D images. Postoperative variables considered for evaluating between-group differences in clinical outcomes included diet resumption period after surgery, postoperative hospital length-of-stay, outpatient department follow-up period, surgical time, and postoperative surgery-related complications (blood loss and open conversion). Results We analyzed 278 acute cholecystitis patients (Group A, n=116; Group B, n=162). Compared to group B, group A had a significantly reduced surgical time and postoperative hospital stay. Although underlying diseases and abdominal surgical history were more prevalent in the 3D LC group, no significant between-group differences in blood loss and open conversion rate were observed. Conclusions The 3D imaging system offered many advantages over 2D LC, including reduced surgical time and shorter postoperative hospital stay; therefore, it has significance in reducing hospital costs.

Laparoscopy for living donor left nephrectomy: Comparison of three-dimensional and two-dimensional vision. Clin Transplant 2019; 33:e13745. [PMID: 31665808 DOI: 10.1111/ctr.13745] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 08/29/2019] [Accepted: 10/21/2019] [Indexed: 12/01/2022]
Abstract
The main objective of this preliminary study was to evaluate the feasibility and safety of 3-D laparoscopic living donor left nephrectomy (LDLN). The secondary objective was to compare intraoperative and postoperative outcomes between 3-D and 2-D laparoscopic LDLN. All patients who underwent a laparoscopic LDLN from January 2015 to April 2018 in a university center were included. All surgeries were performed by three experienced surgeons. Seventy three patients were included the following: 16 underwent a 3-D laparoscopic LDLN (3-D group), and 57 underwent a 2-D laparoscopic LDLN (2-D group). Operative time and warm ischemia time (WIT) were significantly lower in the 3-D group (operative time: 80.9 ± 10.2 vs 114.1 ± 32.3 minutes in the 3-D and 2-D groups, P = .0002) (WIT: 1.7 ± 0.6 vs 2.3 ± 0.9 minutes in the 3-D and 2-D groups, P = .02). No conversion to open surgery occurred in both groups. Length of hospital stay was significantly shorter in the 3-D group. No major postoperative complications (Clavien ≥ III) occurred. One-year postoperative GFR was similar to 3-D and 2-D groups. Our preliminary study demonstrates that 3-D laparoscopic LDLN is a feasible and safe surgical procedure. Intraoperative and postoperative outcomes were similar in both 2-D and 3-D vision systems, but 3-D vision systems allow reduction in WIT and operative time.

Abstract
OBJECTIVE To determine whether top-view and side-view camera angles, which putatively impose different cognitive demands, differentially affect the resumption lag in a visual-motor task relevant to laparoscopic surgery. BACKGROUND Prior research showed that the time to resume a primary task after performing an interrupting task (resumption lag) increases with increases in the subjective workload of the primary task. Camera views used in laparoscopic surgery provide different views of the anatomy and have different cognitive costs and associated levels of workload. METHOD Participants completed a peg transfer task while interrupted with a mental rotation task of different durations and angles of stimulus rotation. RESULTS Participants required significantly more time to resume the peg transfer task when using a side view than a top view and when interrupted for a longer duration. Participants' ratings of subjective workload were consistent with these patterns of performance data; the side view resulted in longer resumption lags and was rated as greater in mental demand. Additionally, the time needed to resume the peg transfer task decreased across trials for both views. CONCLUSION More time is required to resume an interrupted visual-motor task when it is more cognitively demanding than when it is less cognitively demanding possibly due to needing more time to learn the visual-motor mapping of the task higher in cognitive demand. APPLICATION Training for laparoscopic surgery should include interruptions to allow surgeons to practice resuming a surgery-related task after an interruption and consequently shorten the time needed to resume the surgery-related task.

Abstract
Introduction: This study investigated the oncological and technical advantages of three-dimensional (3D) versus two-dimensional (2D) laparoscopic gastric cancer surgery. Materials and Methods: This study included 68 gastric cancer patients who had undergone laparoscopic distal gastrectomy at Korea University Ansan Hospital (3D group, n = 34; 2D group, n = 34). The surgical outcomes and duration of each phase were compared between the groups. Results: The total operative time with 3D laparoscopy was significantly shorter than with 2D laparoscopy (227.8 ± 39.0 versus 249.6 ± 45.3 minutes; P = .037). There were no significant differences between the groups in the number of gauze pads used, time to first postoperative flatus, and number of harvested lymph nodes (2.0 [1.0-2.0] versus 2.0 [1.0-2.0]; P = .692; 4.0 [4.0-4.0] versus 4.0 [4.0-4.0] days; P = .196; 40.8 ± 16.6 versus 44.0 ± 15.7; P = .412, respectively). The time from omentectomy to right gastric artery ligation and the duration of the reconstruction phase were shorter with 3D than with 2D laparoscopy (62.6 ± 14.5 versus 71.9 ± 18.8 minutes; P = .027; 32.3 ± 7.6 versus 47.7 ± 16.8 minutes; P < .001). Conclusion: In a procedure requiring spatial perception, the operative time was shortened by introducing 3D laparoscopy. Despite the anticipation of a better view for lymph node dissection, the 3D image showed no advantage. Further study may be required by novice surgeons.

Abstract
BACKGROUND There are 2 endoscopic surgical techniques that implement 3-dimensional (3D) vision to overcome visual misperception: 3D endoscopy and the da Vinci surgical system. 3D endoscopy has several advantages, such as the presence of tactile feedback and easy implementation, at lower costs. We aimed to assess whether 3D endoscopy could be an alternative to the robot during living donor nephrectomy. METHODS Between April 2015 and April 2016, we prospectively collected data on 40 patients undergoing 3D endoscopic living donor nephrectomies in 1 center, performed by a da Vinci-certified surgeon. Data on donors' perioperative results and recipient and graft survival were collected. These data were compared to 40 robot-assisted donor nephrectomies performed in the same center (between January 2012 and May 2014). RESULTS Baseline characteristics for both groups were comparable. Intraoperative results showed a significantly shorter median skin-to-skin time of 138.5 minutes (125.8-163.8) versus 169.0 (141.5-209.8) minutes in favor of the 3D group (P = 0.001). Warm ischemia time (P = 0.003) and hilar phase for both single (1 artery and vein) and multiple anatomies (≥1 artery and/or vein [P = 0.002 and P = 0.010, respectively]) were also significantly reduced in favor of the 3D group, with a flat learning curve. Follow-up demonstrated no readmissions nor significant differences for donors, recipients, and graft survival. CONCLUSIONS 3D endoscopy may be a good alternative to robot-assisted donor nephrectomy because morbidity, graft, and recipient survival were comparable, with a significantly shorter median skin-to-skin time, warm ischemia time, and hilar dissection phase. Furthermore, implementation was easy and at lower costs, whereas tactile feedback was preserved.

Abstract
Objective. The introduction of advanced endoscopic systems, such as the Storz Image1S and the Olympus Endoeye, heralds a new era of 3-dimensional (3D) visualization. The aim of this report is to provide a comprehensive overview of the neurophysiology of 3D view, its relevance in videoscopy, and to quantify the benefit of the new 3D technologies for both rigid and articulated instruments. Method. Sixteen medical students without any laparoscopic experience were trained each for a total of 27 hours. Proficiency scores were determined for rigid and articulated instruments under 2D and 3D visualization conditions. Results. A reduction in execution time of 14%, 28%, and 36% was seen for the rigid instruments, the da Vinci, and Steerable instruments, respectively. A reduction in errors of 84%, 92%, and 87% was seen for the rigid instruments, the da Vinci, and Steerable instruments, respectively. Conclusion. 3D visualization greatly augments endoscopic procedures. The advanced endoscopic systems employed in the recent study caused no visual fatigue or discomfort. The benefit of 3D was most distinct with articulated instruments.

Abstract
A systematic review was undertaken to assess the technology used to create stereovision for human perception. Adverse effects associated with artificial stereoscopic technology were reviewed with an emphasis on the impact of surgical performance in the operating room. MEDLINE/PubMed library databases were used to identify literature published up to Aug 2017. In the past 60 years, four major types of technologies have been used for reconstructing stereo images: anaglyph, polarization, active shutter, and autostereoscopy. As none of them can perfectly duplicate our natural stereoperception, user exposure to this artificial environment for a period of time can lead to a series of psychophysiological responses including nausea, dizziness, and others. The exact mechanism underlying these symptoms is not clear. Neurophysiologic evidences suggest that the visuo-vestibular pathway plays a vital role in coupling unnatural visual inputs to autonomic neural responses. When stereoscopic technology was used in surgical environments, controversial results were reported. Although recent advances in stereoscopy are promising, no definitive evidence has yet been presented to support that stereoscopes can enhance surgical performance in image-guided surgery. Stereoscopic technology has been rapidly introduced to healthcare. Adverse effects to human operators caused by immature technology seem inevitable. The impact on surgeons working with this visualization system needs to be explored and its safety and feasibility need to be addressed.

Abstract
STUDY DESIGN Technical report. OBJECTIVES Conventional 2-dimensional (2D) video-assisted thoracoscopy (VATS) is a technical procedure mainly performed by experienced surgeons. The technique may, however, come with difficulties in hand-eye coordination and estimation of depth. Three-dimensional thoracoscopy can help overcome these difficulties by providing a stereoscopic 3D view. The objective of this study is to report the first experience and results with 3D thoracoscopy for spine surgery in trauma patients. METHODS The first 4 patients treated with anterior stabilization for traumatic spine fractures using 3D thoracoscopy in an academic hospital are described. Baseline characteristics, operative time, and blood loss were retrospectively collected. This data is compared with a cohort of patients treated in the same center with the conventional 2D technique. Additionally, the treating surgeons' and residents' experience with the technique is described. Surgical equipment consists of 3D compatible video monitors, a videoscope with 2 cameras, and special glasses to be worn by the personnel. RESULTS Four patients were successfully treated using 3D thoracoscopy. Operative time was comparable to that of the conventional 2D technique and less blood loss occurred. No per- or postoperative complications or problems occurred. Per-operative views were of very high quality and provided improved depth perception. Surgeons and residents deemed the technique helpful, especially during technically demanding aspects of the procedure. CONCLUSIONS While a shorter learning curve, decreased surgery time, and blood loss have to be proven in future prospective studies, the first experience with 3D-VATS for spine surgery is positive, and future use in minimally invasive spine surgery seems feasible.

Abstract
BACKGROUND There have been no studies to systematically evaluate the two display (3D vs. 2D) systems regarding both laparoscopic and thoracoscopic surgeries in clinical settings; thus, we conducted one to evaluate the safety and efficacy of different visualization systems (two-dimensional and three-dimensional) during endoscopic surgery (laparoscopy or thoracoscopy) in clinical settings. METHODS A comprehensive search of online databases was performed. Perioperative outcomes were synthesized. Cumulative meta-analysis was performed to evaluate the temporal trend of pooled outcomes. Specific subgroups (laparoscopy vs. thoracoscopy, prospective vs. retrospective study, malignant vs. benign diseases) were examined. Meta-regression was conducted to explore the source of heterogeneity. RESULTS Twenty-three articles were considered in this analysis, of which 7 were thoracoscopic and 16 were laparoscopic surgeries. A total of 2930 patients were recorded, of which 1367 underwent 3D video-assisted surgery and 1563 underwent 2D display. Overall, significantly shorter operating time (SMD -0.69; p = <0.001), less blood loss (SMD -0.26; p = 0.028) and shorter hospital stays (SMD -0.16; p = 0.016) were found in the 3D display group. Meanwhile, the perioperative morbidity (OR 0.92; p = 0.487), retrieved lymph nodes (SMD 0.09; p = 0.081), drainage duration (SMD -0.15; p = 0.105) and drainage volume (SMD 0.00; p = 0.994) were similar between the two groups. Comparison of the overall outcomes in each subset showed consistency in all groups. CONCLUSIONS This up-to-date meta-analysis reveals that the 3D display system is superior to the 2D system in clinical settings with significantly shorter operating time, less blood loss and shorter hospital stay. These findings suggest that, in laparoscopic or thoracoscopic surgeries, 3D endoscopic system is preferable when condition permits. Future efforts should be made on decreasing the side effects of 3D display and increasing its cost-effectiveness.

Abstract
OBJECTIVE The aim is to stabilize the thoracolumbar spine with a thoracoscopically implanted vertebral body replacement (VBR). To improve intraoperative depth perception and orientation, implantation is performed under three-dimensional (3D) thoracoscopic vision. INDICATIONS Vertebral burst fractures at the thoracolumbar junction (A4 AOSpine classification), pseudarthrosis, and posttraumatic instability with increasing kyphosis. CONTRAINDICATIONS Severe pulmonary dysfunctions, pulmonary or thoracic infections, previous thoracic surgery, and pulmonary adhesions. SURGICAL TECHNIQUE The patient is lying in a right lateral decubitus position. Localization of the fractured vertebra. Minimally invasive transthoracic approach. Perform single lung ventilation and insert the 3D thoracoscope two intercostal spaces above the working portal. Utilization of special binocular glasses for 3D vision of the operation field and secure resection of the fractured vertebra. Measurement of the bony defect and insertion of the expandable cage. Control of correct cage position under fluoroscopy. Insertion of a chest tube and inflate the left lung. POSTOPERATIVE MANAGEMENT Chest × ray Remove chest tube when output is <500 ml/24 h Early mobilization on the ward 6 weeks no weight-bearing >5 kg RESULTS: Between 2012 and 2017, 12 patients received a VBR under 3D thoracoscopic vision. After a mean follow up of 26 months, no cage dislocation was noticed and all patients recovered from the initial back pain. Complications were notable in two cases (17%) with a small pneumothorax after removal of the chest tube and postoperative pneumonia in one patient (8%). All responded to conservative treatment. Revision surgery was not necessary.

Abstract
AIM There are reports of visual strains and associated symptoms when operating in a 3D laparoscopic environment. We aimed to study the extent of visual symptoms seen in 3D versus conventional 2D imaging in volunteers performing laparoscopic tasks and study the effect of eye exercises on 3D laparoscopy. METHODS Twenty four consented laparoscopic novices were required to undergo a visual acuity test (Snellen chart) and eye deviation test (Maddox Wing). A battery of specific isolated laparoscopic tasks lasting 30 min was developed to test their ability to detect changes in 2D and 3D environments separately. Before and after the 2D and 3D laparoscopic tasks, subjects were asked to complete a standardised questionnaire designed to scale (from 0 to 10) their visual symptoms (blurred vision, difficulty in refocusing from one distance to another, irritated or burning eyes, dry eyes, eyestrain, headache and dizziness). Participants who underwent 3D laparoscopic tasks were randomized into two groups, those who received two minutes eye exercises before performing the tasks and those who didn't. Independent t-test was used for the statistical analysis of this study. RESULTS Visual symptoms and eye strain were significant in 2D (p < 0.01) and difficulty in refocusing from one distance to another was significant in 3D laparoscopic imaging (p < 0.05). There was no significant effect of the simple eye exercises on relieving the visual symptoms in the 3D group. CONCLUSION Visual symptoms were present in both 2D and 3D imaging laparoscopy. Eye strain was prominent in 2D imaging, while difficulty in refocusing from one distance to another was prominent in 3D. Eye exercises for 3D visual symptoms did not bring any significant improvement.

Abstract
Background Three-dimensional (3D) video systems offer better depth perception and are associated with improved performance during endoscopic or robotic surgery. We compared the impact of a 3D video system with a two-dimensional (2D) video system on a simulation program for uniportal thoracoscopic surgery. Methods We launched an endoscopic simulation program for uniportal surgery using a 3D high-definition video system for training surgeons and medical students. This program included three basic surgical skills: (I) peg transfer, (II) passing a needle through a 3-mm hole, and (III) suturing on a tailor-made skin model. We evaluated the impact of 3D vision during simulation for uniportal surgery in each task. Overall, 113 trainees (85 surgeons in training and 28 medical students) who had not experienced a 3D video system were registered in the program. The three surgical simulation skills were evaluated under 2D and 3D video systems. Results The 3D video system allowed for shorter procedural times [92 participants (80.0%) in task 1, 102 (86.4%) in task 2, and 88 (74.6%) in task 3] and improved performance. Moreover, 65 s in task 1, 145 s in task 2, and 32 s in task 3 were shortened using the 3D video system. Post-simulation survey revealed improved depth perception (n=71, 60.2%) and handling of instruments on the uniportal surgical module (n=39, 33.1%) as advantages of the 3D video system during simulation. Sixty (50.8%) trainees were not negatively affected by the use of the 3D glasses; however, 53 (44.9%) felt eye discomfort during simulation. Conclusions We concluded that the 3D video system has potential advantages, such as improved procedure time and handling of instruments, during basic simulation of uniportal surgery for surgical trainees.

Abstract
Background: In endoscopic operations, direct binocular view, tissue sensation and depth perception get lost. It is still unclear whether the novel three-dimensional (3D) high-definition (HD) cameras are able to compensate the limited senses and how this affects the skill set of users with different endoscopic experience. This study aimed first to evaluate if the 3D technology improves depth perception, precision and space orientation as compared to conventional two-dimensional (2D) HD technology. The second aim was to determine the 3D influence on participants with different endoscopic experience. Methods: A total of 24 participants of different experience levels performed three different tasks on a pelvic trainer using the same thoracoscopic unit in 2D and 3D modes. Results were statistically analysed using Student's t-test and Pearson's product–moment correlation. Results: Across all the participants, we found that 3D optic vision significantly reduced the needed time to perform a defined difficult task in comparison to 2D. This difference was less pronounced in participants with higher experience level. Participants with eyeglasses performed slower in both 2D and 3D in comparison to participants with normal vision. Only participants with normal vision could significantly improve their completion times with 3D optic vision. Conclusions: By testing the novel generation of 3D HD cameras, we could demonstrate that the 3D optic of these systems improves depth perception and space orientation for novices and experienced users and especially inexperienced users benefit from 3D optic.

Abstract
INTRODUCTION After the first feasibility report in 1997, a growing interest has risen in the urologic community for laparoscopic radical prostatectomy (LRP) and several authors have contributed to the evolution of the technique. We attempt a review of the available evidences and provide a broad framework of different technical refinements considering their impact on pentafecta. EVIDENCE ACQUISITION The PubMed/Medline database was searched. Duplicates and "Expert opinion" papers were removed. Studies were included according to the aim of the present paper to present a selected review on LRP and report our personal experience. EVIDENCE SYNTHESIS In 1999 Guillonneau et al. codified their transperitoneal-posterior-antegrade technique for LRP. Since then, several modifications of the transperitoneal approach were published and the extraperitoneal route was also proposed. Sparing the bladder neck and reconstructing the posterior muscolofascial plate were proven to improve continence rate. Nerve-sparing LRP were performed in order to maximize postoperative recovery of the sexual function. Novel techniques to ligate the Santorini plexus and sew the urethrovesical anastomosis provided improvement in operative time, intraoperative blood loss and reduced the incidence of postoperative urinary-leakages. In the recent years, the single-site approach as pushed the limits of LRP and three-dimensional (3D) systems for endoscopic surgery were developed. CONCLUSIONS Thanks to several technical improvements, LRP provides brilliant oncologic and functional outcomes and it is now considered the treatment of choice in many institutions worldwide. Although it is a technically demanding procedure, the recent introduction of 3D systems will reduce the steepness of its learning curve.

Abstract
BACKGROUND Treatment of thoracic spinal dural arteriovenous fistulas (DAVFs) by microsurgery has recently been approached using minimally invasive spine surgery (MISS). The advantages of such an approach are offset by difficult maneuverability within the tubular retractor and by the creation of "tunnel vision" with reduced luminosity to a remote surgical target. OBJECTIVE To demonstrate how the pitfalls of MISS can be addressed by applying 3-D endoscopy to the minimally invasive approach of spinal DAVFs. METHODS We present 2 cases of symptomatic thoracic DAVFs that were not amenable to endovascular treatment. The DAVFs were excluded solely via a minimally invasive approach using a 3-D endoscope. RESULTS Two patients underwent exclusion of a DAVF following laminotomy, one through a midline 5-cm incision and the other through a paramedian 3-cm incision using minimally invasive nonexpandable tubular retractors. The dura opening, intradural exploration, fistula exclusion, and closure were performed solely under endoscopic 3-D magnification. No incidents were recorded and the postoperative course was marked by clinical improvement. Postoperative imaging confirmed the exclusion of the DAVFs. Anatomical details are exposed using intraoperative videos. CONCLUSION When approaching DAVFs via MISS, replacing the microscope with the endoscope remedies the limitations related to the "tunnel vision" created by the tubular retractor, but at the expense of losing binocular vision. We show that the 3-D endoscope resolves this latter limitation and provides an interesting option for the exclusion of spinal DAVFs.

Abstract
OBJECTIVE To determine the relative safety and efficacy of 3D laparoscopic gastrectomy and 2D laparoscopic surgery in patients with gastric cancer. BACKGROUND There is still a lack of randomized controlled trials regarding the safety and efficacy of 3D versus 2D laparoscopic surgery for gastric cancer. METHODS A large-scale, phase 3, prospective, randomized controlled trial was conducted. (ClinicalTrials.gov number NCT02327481). RESULTS A total of 438 patients were randomized (3D group: 219 cases; 2D group: 219 cases) between January 1, 2015, and April 1, 2016; 19 patients were excluded. Finally, data from 419 patients were analyzed (3D group: 211 cases; 2D group: 208 cases). There were no differences between the 2 groups regarding the operation time (3D versus 2D, 176 ± 35 min vs. 174 ± 33 min, P = .562). The intraoperative blood loss in the 3D group was somewhat less than in the 2D group (61 ± 83 mL vs. 82 ± 119 mL, P = .045). Further analysis suggested that the use of 3D laparoscopic surgery was a protective factor against excessive blood loss (≥200 mL). CONCLUSION 3D laparoscopic gastrectomy did not shorten the operation time compared with 2D laparoscopic gastrectomy, but provided the benefit of less intraoperative blood loss and a lesser occurrence of excessive bleeding than the conventional 2D laparoscopic gastrectomy; the clinical value of the difference is limited.

Abstract
Video-assisted thoracic surgery (VATS) allows to treat pulmonary and mediastinal diseases although two-dimensional (2D) imaging can make difficult to estimate the morphological and topographical characteristics of a lesion. Some technical aspects have certainly been corrected with the introduction of robot-assisted thoracic surgery (RATS), although not widespread in less economically developed countries. As an emerging imaging system and technique, 3D VATS is an interesting resource for thoracic surgeons and it may be a proper and valid aid in minimally-invasive surgery, but not an alternative or a compromise to the most expensive robotic technology. The purpose of the study was to carefully analyze the different experiences reported in literature in order to evaluate the state of art of 3D VATS method in lung excision.

Abstract
Effects of different visual displays on the time and precision of bare-handed or tool-mediated eye-hand coordination were investigated in a pick-and-place-task with complete novices. All of them scored well above average in spatial perspective taking ability and performed the task with their dominant hand. Two groups of novices, four men and four women in each group, had to place a small object in a precise order on the centre of five targets on a Real-world Action Field (RAF), as swiftly as possible and as precisely as possible, using a tool or not (control). Each individual session consisted of four visual display conditions. The order of conditions was counterbalanced between individuals and sessions. Subjects looked at what their hands were doing 1) directly in front of them (“natural” top-down view) 2) in top-down 2D fisheye view 3) in top-down undistorted 2D view or 4) in 3D stereoscopic top-down view (head-mounted OCULUS DK 2). It was made sure that object movements in all image conditions matched the real-world movements in time and space. One group was looking at the 2D images with the monitor positioned sideways (sub-optimal); the other group was looking at the monitor placed straight ahead of them (near-optimal). All image viewing conditions had significantly detrimental effects on time (seconds) and precision (pixels) of task execution when compared with “natural” direct viewing. More importantly, we find significant trade-offs between time and precision between and within groups, and significant interactions between viewing conditions and manipulation conditions. The results shed new light on controversial findings relative to visual display effects on eye-hand coordination, and lead to conclude that differences in camera systems and adaptive strategies of novices are likely to explain these.

Abstract
In the late 1980s the first laparoscopic cholecystectomies were performed prompting a sudden rise in technological innovations as the benefits and feasibility of minimal access surgery became recognised. Monocular laparoscopes provided only two-dimensional (2D) viewing with reduced depth perception and contributed to an extended learning curve. Attention turned to producing a usable three-dimensional (3D) endoscopic view for surgeons; utilising different technologies for image capture and image projection. These evolving visual systems have been assessed in various research environments with conflicting outcomes of success and usability, and no overall consensus to their benefit. This review article aims to provide an explanation of the different types of technologies, summarise the published literature evaluating 3D vs 2D laparoscopy, to explain the conflicting outcomes, and discuss the current consensus view.

Abstract
BACKGROUND Major limitations of conventional 2-dimensional (2D) laparoscopy are a lack of depth perception and spatial orientation. Three-dimensional (3D) laparoscopy was developed to overcome the limitations of the 2D technique. However, it has not been widely accepted due to a lack of conclusive evidence of benefit. The aim of this study was to evaluate the effect of 3D laparoscopy on the operative performance during elective laparoscopic right colectomy. METHODS A total of 58 consecutive patients underwent laparoscopic colectomy for right-sided colon cancer by a single experienced surgeon between January 2014 and July 2015. Patients were classified into 2 groups according to the vision system of laparoscopy: 27 patients were operated by 3D laparoscopy (3D group, n=27) and 31 patients were performed by 2D laparoscopy (2D group, n=31). Data of these patients were collected and analyzed retrospectively. RESULTS The operative time was significantly shorter in the 3D group than in the 2D group (130.5±27.6 vs. 152.2±28.9 min, P=0.005). There was no significant difference in blood loss in the 3D group when compared with the 2D group. There was no operative mortality in the 2 groups. The number of lymph nodes resected was similar in both groups. Time to pass the first flatus and postoperative hospital stay showed no significant differences between the 2 groups. The postoperative complication rate for the 3D and the 2D groups were similar: 14.8% (4/27) and 9.7% (3/31), respectively. CONCLUSIONS 3D laparoscopy appears to reduce the performance time of laparoscopic colectomy when compared with 2D laparoscopy. Further studies are required to address the role of the 3D vision system in laparoscopic colectomy.

Abstract
Introduction Minimally invasive operative techniques are being used increasingly in gynaecological surgery. The expansion of the laparoscopic operation spectrum is in part the result of improved imaging. This study investigates the practical advantages of using 3D cameras in routine surgical practice. Materials and Methods Two different 3-dimensional camera systems were compared with a 2-dimensional HD system; the operating surgeon's experiences were documented immediately postoperatively using a questionnaire. Results Significant advantages were reported for suturing and cutting of anatomical structures when using the 3D compared to 2D camera systems. There was only a slight advantage for coagulating. The use of 3D cameras significantly improved the general operative visibility and in particular the representation of spacial depth compared to 2-dimensional images. There was not a significant advantage for image width. Depiction of adhesions and retroperitoneal neural structures was significantly improved by the stereoscopic cameras, though this did not apply to blood vessels, ureter, uterus or ovaries. Conclusion 3-dimensional cameras were particularly advantageous for the depiction of fine anatomical structures due to improved spacial depth representation compared to 2D systems. 3D cameras provide the operating surgeon with a monitor image that more closely resembles actual anatomy, thus simplifying laparoscopic procedures.

Abstract
INTRODUCTION Laparoscopic reconstructive surgery is associated with a steep learning curve related to the use of two-dimensional (2D) vision and rigid instruments. With the advent of robotic surgery, three-dimensional (3D) vision, and articulated instruments, this learning curve has been facilitated. We present a hybrid alternative to robotic surgery, using laparoscopy with 3D vision and articulated shears. OBJECTIVE To compare outcomes of children undergoing pyeloplasty using 3D laparoscopy with articulated instruments with those undergoing the same surgery using standard laparoscopy with 2D vision and rigid instruments. STUDY DESIGN Medical charts of 33 consecutive patients with ureteropelvic junction obstruction who underwent laparoscopic pyeloplasty by a single surgeon from 2006 to 2013 were reviewed in a retrospective manner. The current 3D cohort was compared with the previous 2D cohort. Data on age, weight, gender, side, operative time, dimension (2D = 19 patients, 3D = 8 patients), presence of a crossing vessel, length of hospital stay, and complication rate were compared between the two groups. Articulating shears were used for pelvotomy and spatulation of the ureter in the 3D group. Statistical tests included linear regression models and chi square tests for trends using STATA software. RESULTS Operative time per case was decreased by an average of 48 min in the group undergoing 3D laparoscopic pyeloplasty compared with the group undergoing 2D laparoscopic pyeloplasty (p = 0.02) (Figure). Complication rate and length of hospital stay were not significantly affected by the use of 3D laparoscopy. DISCUSSION These favorable results are in accordance with previous literature emphasizing the importance of 3D vision in faster and more precise execution of complex surgical maneuvers. The use of flexible instruments has also helped overcome the well-described delicate step of a dismembered pyeloplasty, namely the pelvotomy and ureteral spatulation. Limitations of this study are those inherent to the retrospective study design. CONCLUSION The use of 3D vision endoscopy with articulating instruments blurs the distinction between current robotic-assisted and conventional laparoscopic technology, and provides a hybrid alternative deserving further attention.

Impact of Training on Three-Dimensional versus Two-Dimensional Laparoscopic Systems on Acquisition of Laparoscopic Skills in Novices: A Prospective Comparative Pilot Study. BIOMED RESEARCH INTERNATIONAL 2016; 2016:4197693. [PMID: 27995141 PMCID: PMC5138442 DOI: 10.1155/2016/4197693] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/25/2016] [Revised: 10/14/2016] [Accepted: 10/26/2016] [Indexed: 01/23/2023]
Abstract
In this prospective educational study, 10 medical students (novices) were randomized to practice two basic laparoscopic tasks from the MISTELS program, namely, Pegboard Transfer (PT) and Intracorporeal Knot Tying (IKT) tasks, using either a 2D or a 3D laparoscopic platform. There was no significant difference between both groups in the baseline assessments (PT task: 130.8 ± 18.7 versus 151.5 ± 33.4; p = 0.35) (IKT task: 123.9 ± 41.0 versus 122.9 ± 44.9; p = 0.986). Following two training sessions, there was a significant increase in the scores of PT task for the 2D (130.8 ± 18.7 versus 222.6 ± 7.0; p = 0.0004) and the 3D groups (151.5 ± 33.4 versus 211.7 ± 16.2; p = 0.0001). Similarly, there was a significant increase in the scores of IKT task for the 2D (123.9 ± 41.0 versus 373.3 ± 47.2; p = 0.003) and the 3D groups (122.9 ± 44.9 versus 338.8 ± 28.6; p = 0.0005). However, there was no significant difference in the final assessment scores between 2D and 3D groups for both tasks (p > 0.05). Therefore, 3D laparoscopic systems do not provide an advantage over 2D systems for training novices in basic laparoscopic skills.

Abstract
OBJECTIVE In this study, we evaluated the short-term outcomes following three-dimensional (3D) or two-dimensional (2D) laparoscopic surgery for patients with gastric cancer. BACKGROUND There is a lack of prospective evidence regarding the safety and efficacy of 3D versus 2D laparoscopic surgery for patients with gastric cancer. Therefore, we conducted a phase III single-center, prospective, randomized, controlled trial to compare 3D and 2D laparoscopic surgery for patients with gastric cancer. METHODS We compared operation time, intraoperative blood loss, number of lymph node dissections, morbidity, and mortality between the 3D and 2D groups following laparoscopic surgery for gastric cancer. The study is registered at ClinicalTrials.gov with ID number NCT02327481. RESULTS A total of 228 patients were randomized (3D group 115 cases; 2D group 113 cases) between January 1, 2015 and September 1, 2015. Seven patients who underwent exploratory operations were excluded. Finally, a total of 221 patients were analyzed (3D group 109 cases, 2D group 112 cases). There were no significant differences between the two groups regarding the clinical pathological characteristics, operating time (3D vs. 2D, 184 ± 36 vs. 178 ± 37 min, P = 0.288), number of lymph node dissections (36 ± 14 vs. 37 ± 13, P = 0.698), time to first ambulation (2.27 ± 1.60 vs. 2.04 ± 0.84, P = 0.18), flatus (3.89 ± 1.49 vs. 3.69 ± 1.12, P = 0.255), liquid diet (4.88 ± 1.88 vs. 4.79 ± 1.57, P = 0.684), or duration of postoperative hospital stay (12.52 ± 4.83 vs. 12.63 ± 7.32, P = 0.903). The postoperative complication rates of the 3D and 2D groups were 18.3 and 16.1%, respectively, P = 0.723. No patients died during the postoperative hospital stay. However, the intraoperative blood loss in the 3D group was significantly lower than the 2D group (58 ± 75 vs. 78 ± 72 ml, P = 0.047). CONCLUSION There was no significant difference in operation time and number of lymph node harvested between the 3D and 2D groups; however, 3D laparoscopic surgery may reduce the intraoperative blood loss compared to 2D procedure. Therefore, we conclude that this trial is safe and is thus ongoing.
