Surgeon Preference and Clinical Outcome of 3D Vision Compared to 2D Vision in Laparoscopic Surgery: Systematic Review and Meta-Analysis of Randomized Trials. ANNALS OF SURGERY OPEN 2024; 5:e415. [PMID: 38911624 PMCID: PMC11191999 DOI: 10.1097/as9.0000000000000415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 03/11/2024] [Indexed: 06/25/2024] Open
Abstract
Objective To assess the added value of 3-dimensional (3D) vision, including high definition (HD) technology, in laparoscopic surgery in terms of surgeon preference and clinical outcome. Background The use of 3D vision in laparoscopic surgery has been suggested to improve surgical performance. However, the added value of 3D vision remains unclear as a systematic review of randomized controlled trials (RCTs) comparing 3D vision including HD technology in laparoscopic surgery is currently lacking. Methods A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines with a literature search up to May 2023 using PubMed and Embase (PROSPERO, CRD42021290426). We included RCTs comparing 3D versus 2-dimensional (2D) vision in laparoscopic surgery. The primary outcome was operative time. Meta-analyses were performed using the random effects model to estimate the pooled effect size expressed in standard mean difference (SMD) with corresponding 95% confidence intervals (CIs). The level of evidence and quality was assessed according to the Cochrane risk of bias tool. Results Overall, 25 RCTs with 3003 patients were included. Operative time was reduced by 3D vision (-8.0%; SMD, -0.22; 95% CI, -0.37 to -0.06; P = 0.007; n = 3003; 24 studies; I 2 = 75%) compared to 2D vision. This benefit was mostly seen in bariatric surgery (-16.3%; 95% CI, -1.28 to -0.21; P = 0.006; 2 studies; n = 58; I 2 = 0%) and general surgery (-6.7%; 95% CI, -0.34 to -0.01; P = 0.036; 9 studies; n = 1056; I 2 = 41%). Blood loss was nonsignificantly reduced by 3D vision (SMD, -0.33; 95% CI, -0.68 to 0.017; P = 0.060; n = 1830; I 2 = 92%). No differences in the rates of morbidity (14.9% vs 13.5%, P = 0.644), mortality (0% vs 0%), conversion (0.8% vs 0.9%, P = 0.898), and hospital stay (9.6 vs 10.5 days, P = 0.078) were found between 3D and 2D vision. In 15 RCTs that reported on surgeon preference, 13 (87%) reported that the majority of surgeons favored 3D vision. Conclusions Across 25 RCTs, this systematic review and meta-analysis demonstrated shorter operative time with 3D vision in laparoscopic surgery, without differences in other outcomes. The majority of surgeons participating in the RCTs reported in favor of 3D vision.

Abstract
BACKGROUND Technological development has offered laparoscopic colorectal surgeons new video systems to improve depth perception and perform difficult task in limited space. The aim of this study was to assess the cognitive burden and motion sickness for surgeons during 3D, 2D-4 K or 3D-4 K laparoscopic colorectal procedures and to report post-operative data with the different video systems employed. METHODS Patients were assigned to either 3D, 2D-4 K or 3D-4 K video and two questionnaires (Simulator Sickness Questionnaire-SSQ- and NASA Task Load Index -TLX) were used during elective laparoscopic colorectal resections (October 2020-August 2022) from two operating surgeons. Short-term results of the operations performed with the three different video systems were also analyzed. RESULTS A total of 113 consecutive patients were included: 41 (36%) in the 3D Group (A), 46 (41%) in the 3D-4 K Group and 26 (23%) in the 2D-4 K Group (C). Weighted and adjusted regression models showed no significant difference in cognitive load amongst the surgeons in the three groups of video systems when using the NASA-TLX. An increased risk for slight/moderate general discomfort and eyestrain in the 3D-4 K group compared with 2D-4 K group (OR = 3.5; p = 0.0057 and OR = 2.8; p = 0.0096, respectively) was observed. Further, slight/moderate difficulty focusing was lower in both 3D and 3D-4 K groups compared with 2D-4 K group (OR = 0.4; p = 0.0124 and OR = 0.5; p = 0.0341, respectively), and higher in the 3D-4 K group compared with 3D group (OR = 2.6; p = 0.0124). Patient population characteristics, operative time, post-operative staging, complication rate and length of stay were similar in the three groups of patients. CONCLUSIONS 3D and 3D-4 K systems, when compared with 2D-4 K video technology, have a higher risk for slight/moderate general discomfort and eyestrain, but show lower difficulty focusing. Short post-operative outcomes do not differ, whichever imaging system is used.

J Obstet Gynaecol Res 2023; 49:1028-1035. [PMID: 36535541 DOI: 10.1111/jog.15524] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 12/05/2022] [Indexed: 12/24/2022]
Abstract
AIM The gold standard to treat an apical pelvic organ prolapse is the abdominal route via a sacrocolpopexy, which is also reproduced by laparoscopic route. A laparoscopic sacrocolpopexy however, requires surgical expertise. Three-dimensional (3D) laparoscopy has been developed to overcome the lack of depth perception, that is a known disadvantage of conventional two-dimensional (2D) laparoscopy. This procedure can accelerate the learning curve and optimize the intra-, peri-, and postoperative outcomes. This study aims to compare 3D laparoscopy to traditional 2D laparoscopy for sacrocolpopexy. METHODS Data from 132 patients who underwent a sacrocolpopexy with 2D or 3D laparoscopy in Department of Obstetrics and Gynecology, University Medical Center of the Johannes Gutenberg University, between June 2012 and September 2021, were collected retrospectively. Seventy-one laparoscopic sacrocolpopexy operations in 2D (n = 23) and 3D (n = 48) group were reviewed and compared regarding the duration of surgery, blood loss and the length of hospital admission as primary objectives. RESULTS There were no differences in the baseline demographics between the two groups. The estimated blood loss (1.0 (±0.6) g/dL vs 1.7 (±1.0) g/dL, p = 0.010), and duration of surgery (115.4 (±34.7) min. vs 134.7 (±26.2) min., p = 0.012) was significantly better in favor of 3D laparoscopy. The length of hospital stay was comparable in both groups (p = 0.833). Furthermore, no differences were observed between the groups regarding other surgical outcomes. CONCLUSION 3D laparoscopy shows a significant benefit in terms of estimated blood loss and surgery duration among complex urogynecological surgeries compared to traditional 2D laparoscopy.

Abstract
BACKGROUND There are few studies focused on the short-term results of laparoscopic right hemicolectomy performed with 2D (two-dimension) or 3D (three-dimension) video technology and none on the oncologic effects. The aim of the study was to assess the long-term results of laparoscopic right hemicolectomy (LRH) with intracorporeal anastomosis using 3D or 2D video in patients with right colon cancer with at least three years of oncologic follow-up. METHODS Data from patients undergoing laparoscopic right hemicolectomy (LRH) with intracorporeal anastomosis for cancer in an 11-year period (June 2008-June 2019) and ≥ 3 years of follow-up were prospectively collected. Surgical procedures were performed by two expert laparoscopic surgeons. RESULTS 111 patients were included in the study: 56 (50.5%) in the 3D group and 55 (49.5%) in the 2D group. Tumor stage and number of lymph nodes harvested were similar. Overall and disease-free survival were not different in the two groups. Local recurrence occurred in none of the patients, and distant metachronous metastases were similar in the two groups. A propensity score weighting approach was used to account for potential confounding related to patients' nonrandom allocation to the 2 groups. The effects of the intervention on postoperative outcomes were assessed with a weighted regression approach. CONCLUSIONS Laparoscopic 3D technology allows similar oncological results as 2D vision in LRH with intracorporeal anastomosis. Larger prospective randomized studies might confirm these results in the long-term follow-up.

Abstract
BACKGROUND Operative microscope (OM) has greatly advanced modern spine surgery, but remains limited by several drawbacks. Therefore, a three-dimensional (3D) high-definition (HD) exoscope (EX) (Kestrel View II, Mataka Kohli, Japan) system has been developed and used as an alternative to the OM. The aim of this study was to assess and compare the perioperative data and clinical outcomes of anterior cervical discectomy and fusion (ACDF) procedure with either an EX or OM. METHODS Forty-eight patients with cervical spondylotic myelopathy (CSM) underwent ACDF assisted by the EX or OM between January 2019 and December 2019. We collected and compared data on operative time, intraoperative bleeding, postoperative hospitalization stay, complications, and clinical outcomes between the two groups. The clinical outcomes were evaluated by using visual analogue scale (VAS) scores, Japanese Orthopedic Association (JOA) scores, the recovery rate of JOA scores, and Odom criteria. RESULTS The operative time in the EX group was significantly shorter than that in the OM group (P < 0.05). The VAS and JOA scores were significantly improved in both groups after surgery (P < 0.05). In addition, the VAS scores in the EX group were significantly lower than those in the OM group at 1 week postoperatively (P < 0.05). The good-to-excellent outcome rates were 90.48 and 88.89% in the EX group and OM group, respectively, whereas the complication occurrence rates of the EX group and OM group were 4.76 and 11.11%, respectively. CONCLUSIONS EX-assisted and OM-assisted ACDF resulted in similar clinical outcomes for CSM, while EX-assisted surgery may be related to a short operative time and fewer complications.

J Cardiothorac Surg 2021; 16:302. [PMID: 34656152 PMCID: PMC8520266 DOI: 10.1186/s13019-021-01685-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 10/07/2021] [Indexed: 11/24/2022] Open
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
OBJECTIVE This study aimed to compare the surgical outcomes of three-dimensional (3D) and two-dimensional (2D) laparoscopic myomectomy. STUDY DESIGN A total of 64 patients with symptomatic uterine fibroids were randomly assigned to either the 3D (n = 32) group or the 2D group (n = 32). The primary outcomes were the operative blood loss and change in hemoglobin levels. The secondary outcome was operative time. RESULTS There were no differences in the baseline demographics between the two groups. The 3D and 2D groups were not significantly different in terms of operative blood loss (129.5 ± 86.5 mL vs. 140.9 ± 89.8 mL, P = 0.412), change in serum hemoglobin levels (1.4 ± 1.6 g/dL vs. 1.6 ± 1.6 g/dL, P = 0.553), and operative time (77.4 ± 37.8 min vs. 82.4 ± 35.4 min, P = 0.344). Furthermore, no differences were observed between the groups with regard to other surgical outcomes. CONCLUSION The 3D imaging system had no additional surgical benefit in laparoscopic myomectomy compared with to the conventional 2D imaging system.

Abstract
Purpose The aim of this study was to compare the short-term outcomes of two-dimensional (2D) and three-dimensional (3D) laparoscopic surgery for total extraperitoneal (TEP) primary inguinal hernia repair. Methods This was a single-center, retrospective, observational database study of 38 patients who underwent laparoscopic TEP inguinal hernia repair from March 1, 2019 to August 30, 2019 at Kyung Hee University Hospital at Gangdong in Seoul, Korea. Results There was no significant difference in sex ratio, age, or body mass index between the two groups. The 2D group had two patients with direct hernia and 18 patients with indirect hernia. The 3D group had five patients with direct hernia, 11 patients with indirect hernia, and two patients with femoral hernia. The mean operation time was 38.2 minutes in the 2D group compared with 37.2 minutes in the 3D group. There was no severe intraoperative bleeding in either group. During the operation, peritoneal tearing occurred in 12 out of 20 patients in the 2D group compared with five out of 18 patients in the 3D group (p = 0.02). The average length of hospital stay was 1.3 days in both groups. The numeric rating scale score was 3.3 and 3 in the 2D group and the 3D group, respectively. In the 2D group, two patients revisited the outpatient clinic because of the postoperative occurrence of seroma and varicocele. Conclusion A 3D laparoscopic surgery is feasible and safe for inguinal hernia repair and showed less peritoneal tearing compared with 2D laparoscopic surgery for primary inguinal hernia repair.

We developed a new technique to reduce the length of the enteric defect to be closed during intracorporeal anastomosis in laparoscopic right hemicolectomy (LRH), also avoiding the need to suture the first part of the anastomosis in a deep space with an acute angle. From January 2017, after the ileo-colic anastomosis was completed, an additional stapler cartridge was applied starting at the colonic rim and including the small bowel part of the anastomosis. The isoperistaltic fashion of the ileo-colonic anastomosis was maintained. The remaining defect left to be closed was 2-3 cm. We compared the results of the novel technique with those of the 'standard' closure (full-length enterotomy). In the last 30 months, this technique was successfully used in 32 patients (Group A), compared with 33 patients (2012-2016) operated with 'standard' closure (Group B). Age, BMI and post-operative stage distribution were similar. The mean operative time was 175.2 min (± 36.7) in Group A and 165.9 min (± 42.5) in Group B (p = ns), with 53.1% and 27.3% of associated procedures (cholecystectomy, ovariectomy, etc.), respectively (p < 0.05). Overall morbidity rate was 28.1% and 30.3% (Group A vs Group B, p = ns), with no anastomotic bleeding/leak in either group. This technique, which simplifies the closure of the enteric defect after LRH with intracorporeal anastomosis is safe, reproducible and easy to learn. It might help more surgeons to perform a fully laparoscopic procedure in right hemicolectomy, offering the advantages of intracorporeal anastomosis to their patients.

Abstract
Background Video-assisted thoracoscopic surgery (VATS) has been widely used in the lung resections. Reports regarding three-dimension (3D) single-port VATS are very limited. The purpose of this study is to evaluate the perioperative outcomes of 3D single-port VATS in a single medical center. Methods Totally 523 clinical stage I lung cancer patients underwent surgical resection through VATS operation between September 2016 and October 2017 in our single institution were retrospectively collected and 374 were enrolled. The comparison between 3D single-port VATS and conventional VATS (c-VATS), single-port VATS was conducted focusing on intraoperative and postoperative outcomes. Continuous and categorical variables were analyzed through SPSS software. Results The 3D singe-port VATS demonstrated no significant difference neither on the intraoperative outcomes including the operative time and the intraoperative blood loss nor the postoperative outcomes including the length of drainage duration and postoperative complications when against c-VATS and single-port VATS. Besides, 3D singe-port VATS elucidated comparable ability of lymph node dissection with c-VATS in subgroup analysis (P=0.192), both of which were better than single-port VATS group (P<0.001). What’s more, the rate of conversion as well as hospital stays of 3D single-port group were also comparable. In subgroup analysis, 3D singe-port VATS also elucidated its safety and feasibility when dealing with routine thoracic surgeries including lobectomy and segmentectomy. Conclusions 3D single-port VATS, integrating the advantages of single-port VATS and three-dimensional vision of 3D VATS, is a safe and feasible technique and is promising for next-generation thoracoscopic surgery.

Oper Neurosurg (Hagerstown) 2020; 17:518-524. [PMID: 31140555 DOI: 10.1093/ons/opz081] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2016] [Accepted: 12/25/2019] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND For decades, the operating microscope has been the "gold standard" visualization device in neurosurgery. The development of endoscopy revolutionized different surgical disciplines, whereas in neurosurgery, the endoscope is commonly used as an additional device more than as single visualization tool. Invention of a 3D exoscope system opens new possibilities in visualization and ergonomics in neurosurgery. OBJECTIVE To assess the prototype of a 3D exoscope (3D exoscope, year of manufacture 2015, FA Aesculap, Tüttlingen, Germany) as neurosurgical visualization device in comparison to a standard operating microscope. METHODS A pterional approach was performed in 3 ETOH-fixed specimens (6 sides). A standard operating microscope was compared to a 3D exoscope prototype. Dimensions like visual field, magnification, illumination, ergonomics, depth effect, and 3D impression were compared. RESULTS In all approaches, the structures of interest could be clearly visualized with both devices. Magnification showed similar results. The exoscope had more magnification potential, whereas the visual quality got worse in higher magnification levels. The illumination showed better results in the microscope. Surgeons felt more comfortable with the 3D exoscope, concerning ergonomic considerations. Depth effect and 3D impression showed similar results. None of the surgeons felt uncomfortable using the exoscope. CONCLUSION The operating microscope is the gold standard visualization tool in neurosurgery because of its illumination, stereoscopy, and magnification. Nevertheless, it causes ergonomic problems. The prototype of a 3D exoscope showed comparable features in visual field, stereoscopic impression, and magnification, with a clear benefit concerning the ergonomic possibilities.

Abstract
BACKGROUND Two-dimensional high-definition (2D HD) endovision system is preferred for laparoscopic surgery. Recently, new generation three-dimensional (3D) HD and ultra-HD (4K) endovision systems are introduced to improve the safety and efficacy of laparoscopic surgery. There is limited evidence on superiority of one technology over the others. This experimental trial was designed to evaluate 2D HD, 3D HD and 4K HD endovision systems in performance of standardized tasks. METHODS This was a randomized, cross-over experimental study. Twenty-one surgical residents who were exposed to laparoscopic surgery were enrolled. Participants were randomly assigned into three groups. Each group performed standardised tasks i.e. peg transfer, precision cutting, navigating in space and intra-corporeal suturing using 2D HD, 4K HD and 3D HD endovision systems on a box trainer. Procedures were recorded as 2D HD videos and analysed later. Participant's perceived workload was assessed using Surg-TLX questionnaire. Primary endpoints were execution time in seconds and error score. Secondary endpoint was workload assessment. RESULTS The 3D HD had shorter execution time compared to 2D HD and 4K HD in all tasks except precision cutting (p = 0.004, 0.03, 0.001, 0.001 and p = 0.002, 0.191, 0.006, 0.005 in peg transfer, precision cutting, navigating in space and intra-corporeal suturing respectively). The 4K HD was significantly faster than 2D HD only in navigating in space task (p = 0.002). The error score between 3D HD and 4K HD were comparable in all tasks. The 2D HD had significantly more error scores compared to 4K HD, 3D HD in peg transfer task (p = 0.005, 0.014, respectively). 3D HD had significantly less workload than 2D HD and 4K HD in most of the dimensions of Surg-TLX CONCLUSIONS: 3D HD endovision system in comparison to 2D HD and 4K HD, may lead to faster execution without compromising safety of a task and is associated with less workload.

Abstract
BACKGROUND There are few reports comparing safety and efficacy of 2-D and 3-D video technology in laparoscopic right hemicolectomy. The aim of the study was to assess the short-term results of laparoscopic right hemicolectomy (LHR) with intracorporeal anastomosis with 2-D/3-D video in patients with right colon cancer. METHODS Data from 239 patients undergoing LRH for cancer in a 14-year period (June 2005-January 2020) were prospectively collected. Surgical procedures were performed by two expert laparoscopic surgeons. RESULTS One hundred and fourteen patients were included in the study: 55 (48.2%) operated with 2-D and 59 (51.8%) with 3-D video. Tumor site and postoperative stage distribution were similar. Mean operative time was comparable in the two groups (159.0 ± 48.8 min vs. 17.06 ± 36.0 min, p = ns, group 2-D and 3-D, respectively). Group 3-D patients had a similar percentage of associated procedures (44.1% vs. 29.1%, p = ns). Intraoperative complications were nil in both groups, while postoperative complications were similar (30.9% 2-D vs 25.4% 3-D, p = ns). The mean number of lymph nodes retrieved was similar in group 3-D (26.0 ± 14.6 vs. 22.9 ± 9.3, p = ns) and the length of stay was comparable in 3-D and 2-D patients (8.4 ± 2.6 vs. 9.1 ± 3.3 days, respectively, p = ns). CONCLUSIONS Laparoscopic 3-D vision is as equally effective as 2-D vision in LRH with intracorporeal anastomosis, with a similar proportion of associated procedures and number of lymph nodes retrieved in the same operative time. Further prospective larger randomized studies are necessary to verify if LRH with 3-D video can reduce postoperative complications, compared to 2-D video.

Abstract
PURPOSE Laparoscopy is the standard technique for resecting adrenal tumors worldwide. The main drawbacks of conventional 2D laparoscopy are limited depth perception and tactile feedback. Currently available high-quality 3D laparoscopy systems might improve surgical outcomes for adrenalectomy. We compare the safety and efficacy of 3D versus 2D laparoscopy in the treatment of adrenal tumors. METHODS This case-control study analyzed prospectively collected data from patients with benign or malignant adrenal tumors treated laparoscopically at a single academic medical center between April 2003 and March 2020. We collected demographic, diagnostic, preoperative, and operative variables, and used multiple linear and logistic regression to analyze differences in various short-term outcomes between the two approaches while adjusting for potential confounders. RESULTS We included 150 patients: 128 with benign tumors and 22 with malignant tumors; 95 treated with 3D laparoscopy (case group); and 55 with 2D laparoscopy (control group). After adjustment for patient, surgical, and tumor characteristics, a 2D vision was associated with a longer operative time (β = 0.26, p = 0.002) and greater blood loss (β = 0.20, p = 0.047). There was no significant difference in rates of conversion to open surgery (odds ratio [OR] = 1.47 (95% CI 0.90-22.31); p = 0.549) or complications (3.6% vs. 2.1%; p = 0.624). CONCLUSIONS With experienced surgeons, laparoscopic adrenalectomy was safer and more feasible with the 3D system than with the 2D system, resulting in less operative blood loss and shorter operative time with no differences in rates of conversion to open surgery or postoperative complications. For adrenal tumors, 3D laparoscopy offers advantages over 2D laparoscopy.

Abstract
INTRODUCTION Three-dimensional (3D) laparoscopic vision can improve depth perception. However, it is a question whether 3D vision can improve motion in the depth direction. The aim of this study was to compare the impact of 3D vision on forceps motion in the depth and horizontal directions. METHODS All data were obtained from our previous two studies, where, in total, 40 novices and 20 moderately experienced surgeons participated. A simple phantom task was performed in a training box. The participants were randomly assigned to two groups. Specifically, one group performed the task five times initially under a two-dimensional (2D) system, and the other group started under a 3D system. Both groups then performed the same task five times under the alternative system. Performances were recorded by an optical position tracker. We separately evaluated forceps motion in the x-, y-, and z-axis directions. RESULTS Compared with the findings for 2D vision, the forceps path lengths were significantly decreased among novices and moderately experienced surgeons in almost all tasks under 3D vision. In a comparison of the path length ratio (3D/2D) in each direction, larger reduction was observed for the depth direction among novices, whereas no significant directional difference was noted among moderately experienced surgeons. CONCLUSIONS For novices, 3D laparoscopic vision improves depth perception and may give shorter forceps movement in the depth direction even for simple tasks.

Prospective randomized controlled study for comparison of 2-dimensional versus 3-dimensional laparoscopic distal gastrectomy for gastric adenocarcinoma. Surg Endosc 2020; 35:934-940.

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 Objective evidence is lacking as to the benefit of the addition of 3D vision to conventional laparoscopy in Gynecologic surgery. This study aims to compare 3-D visual system to traditional 2-D laparoscopic visualization for the laparoscopic closure of the vaginal cuff during total laparoscopic hysterectomy by surgeons-in-training [defined as senior OBGYN resident or Minimally Invasive Gynecologic Surgery (MIGS) fellow]. METHODS 51 patients undergoing total laparoscopic hysterectomy at two tertiary care academic hospitals were randomized to two-dimensional or three-dimensional vision system with cuff closure performed by surgeons-in-training. The primary outcome was the time taken for vaginal cuff closure. Secondary outcomes included peri-operative outcomes and assessment of surgeon's perception of ease of cuff closure. RESULTS 27 (52.9%) cases were allocated to cuff closure with the 2D system and 24 (47.1%) cases to closure with the 3D vision system. Patient baseline characteristics were similar between the vision systems. Mean vaginal cuff closure time was not significantly different between 2D and 3D vision (10.1 min for 2D versus 12 min for 3D, p = 0.31). An additional 24 s was added to cuff closure time with each 1 kg/m2 increase in BMI, after controlling for potential confounders (p = 0.003). There was no difference in the surgeon rating of ease of cuff closure between 2D and 3D. Peri-operative outcomes are similar among the two groups. CONCLUSION We did not demonstrate any benefits of 3D vision system over conventional 2D for the task of laparoscopic vaginal cuff suturing performed by surgeons-in-training.

Abstract
BACKGROUND Three-dimensional (3D) laparoscopy improves the surgical skills of novice surgeons and positively affects the learning curve in experimental settings. This study aimed to investigate the effect of a 3D passive polarizing display (3DPPD) and a novel 3D head-mounted display (3DHMD; HMS-3000MT) on the performance of the first laparoscopic inguinal hernia repair by novices and compare both systems with standard high-definition 2D (HD2D) laparoscopy. METHODS Patients with symptomatic inguinal hernia underwent transabdominal preperitoneal (TAPP) approach hernia repair using 3DHMD, 3DPPD, or a conventional HD2D laparoscopic system. All surgeries were performed for the first time by three laparoscopically novice surgeons. Operative performance was compared in terms of the time taken for mesh placement and peritoneal suturing under standardized conditions. Additionally, visual perception parameters and adverse effects were assessed. RESULTS The use of both 3D techniques shortened the time required for mesh placement and peritoneal suturing compared with the conventional HD2D approach. Generally, 3D laparoscopy was superior to HD2D laparoscopy in terms of visual perception parameters such as depth perception, sharpness, ghosting, and contrast. However, compared with the use of HD2D laparoscopy, the use of 3DHMD significantly impaired a surgeon's comfort, with the greatest impairment caused by ear discomfort, headaches, and facial and physical discomforts. CONCLUSIONS The 3DHMD and 3DPPD systems showed clear improvement in first hernia repair laparoscopy by novice surgeons in terms of surgical performance, as well as visual perception; however, the 3DHMD system was not superior to the 3DPPD system. The reduction in training time for new surgeons is obviously advantageous. In this respect, the 3D equipment may be a worthwhile investment.

Abstract
BACKGROUND Laparoscopy is widely used in the urological field. This systematic review and a meta-analysis were conducted to assess the clinical and surgical efficacy of the three-dimensional (3D) laparoscopic system in comparison with two-dimensional (2D) laparoscopy for treatment of different urological conditions. METHODS Following guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses, a systematic literature search in Web of Science, PubMed, Cochrane Library, and EMBase was carried out to identify relevant studies published up to May 2018. Articles published in the English language of both randomized and observational studies comparing 3D and 2D laparoscopic systems in urological surgeries were included. Level of evidence and quality assessments of all included studies were conducted. Interested data were extracted for comparison and meta-analysis. RESULTS Our literature search generated 17 studies comparing 3D and 2D laparoscopic systems in different urological surgeries. Of these, 13 studies containing 548 and 449 patients operated on with 2D and 3D laparoscopic systems, respectively, were included for meta-analysis. These 13 studies were divided into three groups according to surgical type. Group 1: Partial nephrectomy (PN); operative time (p = 0.19), estimated blood loss (EBL) (p = 0.51), dissecting time (p = 0.58), and suturing time (p = 0.28) were not statistically significant between 2D and 3D laparoscopic systems. However, warm ischemia time during PN was significantly shorter during 3D laparoscopy (p < 0.00001). Group 2: Pyeloplasty; this procedure showed no significant difference between the two systems. Group 3: Radical prostatectomy (RP); shorter operative time (p < 0.0001) and lower EBL (p = 0.001) were associated with the 3D laparoscopic system. CONCLUSION Three-dimensional laparoscopy mainly improves the depth of perception, leading to better visibility, which is important for some complex urological surgeries such as PN, pyeloplasty, and RP. Based on our findings, 3D laparoscopy seems to provide better clinical and surgical outcomes in some urological procedures compared with conventional 2D laparoscopy.

Abstract
Objective. Considering the demerits of a high-definition 2-dimensional (HD-2D) system, with its lack of stereopsis, and a conventional 3-dimensional (C-3D) system, which results in a dimmed image, we have recently developed a glasses-free 3-dimensional (GF-3D) display system for reconstruction surgeries such as video-assisted thoracic surgery (VATS) for tracheal reconstruction. Methods. Thoracic surgeons were invited to complete thoracoscopic continuous suture of a transected porcine trachea using the HD-2D, C-3D, and GF-3D systems on separate mornings in randomized order. The duration, numbers of stitches, and distance between every 2 stitches were recorded for every procedure. The surgeons' spontaneous eye blink rate was recorded for 5 minutes before the procedure and the last 5 minutes of the procedure. Results. Fifteen volunteers successfully completed the tracheal reconstruction procedures in this study. Both C-3D (0.403 ± 0.064 stitch/min, P < .001) and GF-3D (0.427 ± 0.079 stitch/min, P < .001) showed significant advantages in speed compared with HD-2D (0.289 ± 0.065 stitch/min). Both C-3D (2.536 ± 2.223 mm, P < .001) and GF-3D (2.603 ± 2.159 mm, P < .001) showed significant advantages in accuracy compared with HD-2D (3.473 ± 3.403 mm). Both HD-2D (1.240 ± 0.642, P < .001) and GF-3D (1.307 ± 0.894, P < .001) showed significant advantages in eye fatigue compared with C-3D (3.333 ± 1.44). Conclusions. All 3 available display systems are efficient for complex VATS. With the help of stereopsis, surgeons can achieve faster operation using C-3D and GF-3D systems in a thoracoscopic simulated setting. GF-3D may be a more effective display system for VATS reconstruction in terms of speed, accuracy, and eye fatigue during operations.

Comparison of 3D endoscopy and conventional 2D endoscopy in gastric endoscopic submucosal dissection: an ex vivo animal study. Surg Endosc 2019; 33:4164-4170. [PMID: 30843096 DOI: 10.1007/s00464-019-06726-w] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2018] [Accepted: 03/01/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND AND OBJECTIVES Conventional endoscopy provides two-dimensional (2D) information without depth information. This study compared three-dimensional (3D) endoscopy and 2D endoscopy using an endoscopic submucosal dissection (ESD) training model to evaluate the utility of 3D endoscopy. METHODS Porcine stomach specimens (7 × 7 cm) were prepared from commercially available resected porcine stomachs and a 10-mm hypothetical lesion was marked at the center of each specimen. Specimens were individually placed in an ESD training model, and subjected to either 2D or 3D ESD. En bloc resection rate, perforation rate, incision time, dissection time, and levels of five eyestrain symptoms (fatigue, pain, blurred vision, head-heaviness, and headache; 100-mm visual analog scale) were compared between the 2D and 3D procedures. In a crossover design, 8 endoscopists each performed two 2D and two 3D procedures. RESULTS All 32 lesions were resected en block, but perforation occurred in one 2D procedure. Incision time was significantly shorter in 3D ESD than in 2D ESD (102.8 ± 42.1 s vs. 135.8 ± 65.7 s, p < 0.05). Dissection time was also significantly shorter in 3D ESD than in 2D ESD (366.3 ± 187.6 s vs. 517.8 ± 282.3 s, p < 0.05). Differences in levels of all symptoms except blurred vision between before and after ESD were larger in 3D ESD than in 2D ESD. CONCLUSIONS Incision time and dissection time were significantly shorter in 3D ESD compared with 2D ESD, but eyestrain was increased. Depth information from 3D images appears to facilitate rapid and stable ESD maneuvers.

Abstract
BACKGROUND AND OBJECTIVES Two-dimensional (2D) images lack depth information and thus provide probabilistic recognition that do not completely match the actual three-dimensional (3D) information. Here, we investigated the operability of 3D endoscopes. METHODS A 3D operation model was developed by passing 20 silk threads through upper and lower plates at 2-mm intervals in front and back rows separated by 1 mm. We evaluated accuracy and time of operating an electrosurgical knife. A successful operation was defined as pulling only a front-row thread; an unsuccessful operation was defined as pulling no thread (miss) or simultaneously pulling front- and back-row threads. Endoscopists (four experts, six trainees) repeated the operation under 2D and 3D conditions until individually accumulating 10 successful attempts under each condition. RESULTS Operation accuracy was significantly higher for 3D compared with 2D in all endoscopists (88.5% vs. 61.3%; p < 0.01) and in both experience groups (trainees: 84.5% vs. 61.2%; experts: 95.2% vs. 61.5%; both p < 0.01). Operation time was significantly shorter for 3D compared with 2D in all endoscopists (12.5 ± 4.1 s vs. 14.8 ± 4.7 s; p < 0.01) and in both experience groups (trainees: 12.8 ± 4.2 s vs. 15.2 ± 4.9 s; experts: 12.1 ± 4.0 s vs. 14.3 ± 4.3 s; both p < 0.01). DISCUSSION Compared with 2D endoscopy, 3D endoscopy significantly improved operation accuracy and shortened operation time, suggesting that 3D endoscopy enables accurate operation by depth information, aiding spatial recognition.

Abstract
BACKGROUND The use of 3D laparoscopic systems is expanding. The European Association of Endoscopic Surgery (EAES) initiated a consensus development conference with the aim of creating evidence-based statements and recommendations for the surgical community. METHODS Systematic reviews of the PubMed and Embase libraries were performed to identify evidence on potential benefits of 3D on clinical practice and patient outcomes. Statements and recommendations were prepared and unanimously agreed by an international surgical and engineering expert panel which were presented and voted at the EAES annual congress, London, May 2018. RESULTS 9967 abstracts were screened with 138 articles included. 18 statements and two recommendations were generated and approved. 3D significantly shortened operative time (mean difference 11 min (8% [95% CI 20.29-1.72], I2 96%)). A significant reduction in complications was observed when 3D systems were used (RR 0.75, [95 CI% 0.60-0.94], I2 0%) particularly for cases involving laparoscopic suturing (RR 0.57 [95% CI 0.35-0.90], I2 0%). In 69 box trainer or simulator studies, 64% concluded trainees were significant faster and 62% performed fewer errors when using 3D. CONCLUSION We recommend the use of 3D vision in laparoscopy to reduce the operative time (grade of recommendation: low). Future robust clinical research is required to specifically investigate the potential benefit of 3D laparoscopy system on complication rates (grade of recommendation: high).

Abstract
BACKGROUND AND AIMS The results of studies comparing two-dimensional (2D) and three-dimensional (3D) laparoscopy have shown variable results. We aimed to review the literature and develop an appropriate instrument to compare 2D and 3D laparoscopy. We further aimed to use the data extracted to perform a pilot study. METHODS Sixty-seven recent articles on 3D laparoscopy were reviewed and data extracted on factors influencing outcome variables. These variables were used to design a pilot study of 28 novices using a randomized crossover design. The results were analyzed using descriptive statistics and the Wilcoxon signed-rank tests. RESULTS Seven themes were identified to influence the outcome of 3D studies: applied technique (1), experience of subjects (2), study design (3), learning curve (4), subjective qualitative reports (5), laparoscopic tasks (6), and chosen outcome variables (7). The consecutively developed five laparoscopic simulation tasks contained placing a rubber band over hooks, ring and pearl transfer, threading a pipe cleaner through loops, and placing a suturise. The pilot study showed a primary benefit of 3D laparoscopy that was unrelated to repetition. Two tasks served well to assess first-time performance, and two tasks promise to serve well to assess a learning curve if performed repeatedly. CONCLUSION We were able to identify important issues influencing the outcome of studies analyzing 3D laparoscopy. These may help evaluate future studies. The developed tasks resulted in meaningful data in favor of 3D visualization, but further studies are necessary to confirm the pilot test results.

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 AND STUDY AIMS Many studies have shown the utility of rigid three-dimensional (3 D) endoscopes in surgery, but few have reported the utility of flexible 3 D endoscopes. This ex vivo study was intended to investigate whether a newly developed 3 D endoscope (GIF-Y0083; Olympus) improves diagnostic accuracy for superficial gastric tumor. METHODS Twelve observers comprising experts, trainees, and novices (4 each) evaluated 2 D and 3 D images of 20 specimens resected by gastric ESD. Evaluation items were diagnostic accuracy of tumor extent and degree of confidence in assessing (a) tumor extent, (b) morphology, and (c) comprehensive recognition. The 2 D and 3 D endoscopy data were compared in a crossover analysis. RESULTS Overall, diagnostic accuracy was significantly higher with 3 D images (88.1 %) than with 2 D images (84.2 %) ( P < 0.01). Comparison by skill level showed that 3 D images significantly improved diagnostic accuracy among novices but not among experts or trainees. Comparison by morphology showed that diagnostic accuracy did not differ significantly for type IIa/IIb lesions but improved significantly for type IIc lesions among trainees and novices. Overall, 3 D images significantly increased the degree of confidence in the assessment of all three items (a - c). Comparison by skill level showed similar results, and comparison by morphology showed that regardless of skill level, the degree of confidence in assessing all items (a - c) increased significantly only when examining type IIc lesions. CONCLUSION Compared with 2 D images, 3 D images significantly improved both diagnostic accuracy of tumor extent and degree of confidence for diagnosing superficial gastric tumor. The utility of the 3 D endoscope was apparent among trainees and novices and for the diagnosis of type IIc lesions.

Abstract
BACKGROUND 3D laparoscopy has proven to be superior to the 2D approach in experimental settings. The aim of the present study was to investigate the influence of 3D laparoscopy using a novel head-mounted display on the performance of defined steps within a laparoscopic inguinal hernia repair. This effect was investigated both in laparoscopically advanced surgeons and in beginners. METHODS Patients suffering from symptomatic inguinal hernia were randomly assigned to laparoscopic hernia repair using either a head-mounted 3D display or a conventional 2D laparoscopic approach. Operative performance of both groups was compared in terms of the time taken for mesh placement and for peritoneal suturing. Additionally, quality of imaging and physical discomfort were assessed. RESULTS The use of a head-mounted 3D display was able to shorten the time required for placement of the mesh as well as that for peritoneal suturing, both for experienced and novice surgeons when compared to the conventional 2D approach. 3D laparoscopy was significantly superior to 2D laparoscopy in terms of depth perception, image sharpness and image contrast. Additionally, increased impairment caused by ghosting effects could not be detected in 3D laparoscopy. Evaluation of image quality was independent of experience in laparoscopic surgery. However, use of a head-mounted 3D display resulted in a significant impairment of surgeon's comfort when compared to 2D laparoscopy. Thereby, the greatest impairment was caused by ear discomfort. CONCLUSIONS This is the first study examining the effect of a head-mounted 3D system on the performance of laparoscopy in a randomized controlled trial (RCT) showing a clear advantage of this system in surgical performance as well as in depth perception and image quality.

Abstract
Since it's introduction, laparoscopic surgery represented a real revolution in clinical practice. The use of a new generation three-dimensional (3D) HD laparoscopic system can be considered a favorable "hybrid" made by combining two different elements: feasibility and diffusion of laparoscopy and improved quality of vision. In this study we report our clinical experience with use of three-dimensional (3D) HD vision system for laparoscopic surgery. Between 2013 and 2017 a prospective cohort study was conducted at the University Hospital of Palermo. We considered 163 patients underwent to laparoscopic three-dimensional (3D) HD surgery for various indications. This 3D-group was compared to a retrospective-prospective control group of patients who underwent the same surgical procedures. Considerating specific surgical procedures there is no significant difference in term of age and gender. The analysis of all the groups of diseases shows that the laparoscopic procedures performed with 3D technology have a shorter mean operative time than comparable 2D procedures when we consider surgery that require complex tasks. The use of 3D laparoscopic technology is an extraordinary innovation in clinical practice, but the instrumentation is still not widespread. Precisely for this reason the studies in literature are few and mainly limited to the evaluation of the surgical skills to the simulator. This study aims to evaluate the actual benefits of the 3D laparoscopic system integrating it in clinical practice. The three-dimensional view allows advanced performance in particular conditions, such as small and deep spaces and promotes performing complex surgical laparoscopic procedures.

Abstract
Background Three-dimensional view in laparoscopic general, gynaecologic and urologic surgery is an efficient, safe and sustainable innovation. The present paper is an extract taken from a full health technology assessment report on three-dimensional vision technology compared with standard two-dimensional laparoscopic systems. Methods A health technology assessment approach was implemented in order to investigate all the economic, social, ethical and organisational implications related to the adoption of the innovative three-dimensional view. With the support of a multi-disciplinary team, composed of eight experts working in Italian hospitals and Universities, qualitative and quantitative data were collected, by means of literature evidence, validated questionnaire and self-reported interviews, applying a final MCDA quantitative approach, and considering the dimensions resulting from the EUnetHTA Core Model. Results From systematic search of literature, we retrieved the following studies: 9 on general surgery, 35 on gynaecology and urology, both concerning clinical setting. Considering simulated setting we included: 8 studies regarding pitfalls and drawbacks, 44 on teaching, 12 on surgeons’ confidence and comfort and 34 on surgeons’ performances. Three-dimensional laparoscopy was shown to have advantages for both the patients and the surgeons, and is confirmed to be a safe, efficacious and sustainable vision technology. Conclusions The objective of the present paper, under the patronage of Italian Society of Endoscopic Surgery, was achieved in that there has now been produced a scientific report, based on a HTA approach, that may be placed in the hands of surgeons and used to support the decision-making process of the health providers.

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
PURPOSE 3D imaging is an upcoming technology in laparoscopic surgery, and recent studies have shown that the modern 3D technique is superior in an experimental setting. However, the first randomized controlled clinical trial in this context dates back to 1998 and showed no significant difference between 2D and 3D visualization using the first 3D generation technique, which is now more than 15 years old. METHODS Positive results measured in an experimental setting considering 3D imaging on surgical performance led us to initiate a randomized controlled pragmatic clinical trial to validate our findings in daily clinical routine. Standard laparoscopic operations (cholecystectomy, appendectomy) were preoperatively randomized to a 2D or 3D imaging system. We used a surgical comfort scale (Likert scale) and the Raw NASA Workload TLX for the subjective assessment of 2D and 3D imaging; the duration of surgery was also measured. RESULTS The results of 3D imaging were statistically significant better than 2D imaging concerning the parameters "own felt safety" and "task efficiency"; the difficulty level of the procedures in the 2D and 3D groups did not differ. Overall, the Raw NASA Workload TLX showed no significance between the groups. CONCLUSION 3D imaging could be a possible advantage in laparoscopic surgery. The results of our clinical trial show increased personal felt safety and efficiency of the surgeon using a 3D imaging system. Overall of the procedures, the findings assessed using Likert scales in terms of own felt safety and task efficiency were statistically significant for 3D imaging. The individually perceived workload assessed with the Raw NASA TLX shows no difference. Although these findings are subjective impressions of the performing surgeons without a clear benefit for 3D technology in clinical outcome, we think that these results show the capability that 3D laparoscopy can have a positive impact while performing laparoscopic procedures.

Abstract
Background Recently to improve depth perception, the performance of three-dimensional (3D) laparoscopic surgeries has increased. However, the effects of laparoscopic training using 3D are still unclear. This study aimed to clarify the effects of using a 3D monitor among novices in the early phase of training. Methods Participants were 40 novices who had never performed laparoscopic surgery (20 medical students and 20 junior residents). Three laparoscopic phantom tasks (task 1: touching markers on a flat disk with a rod; task 2: straight rod transfer through a single loop; and task 3: curved rod transfer through two loops) in the training box were performed ten times, respectively. Performances were recorded by an optical position tracker. The participants were randomly divided into two groups: one group performed each task five times initially under a 2D system (2D start group), and the other group performed each task five times under a 3D system (3D start group). Both groups then performed the same task five times. After the trial, we evaluated the performance scores (operative time, path length of forceps, and technical errors) and the learning curves for both groups. Results Scores for all tasks performed under the 3D system were significantly better than scores for tasks using the 2D system. Scores for each task in the 2D start group improved after switching to the 3D system. However, scores for each task in the 3D start group were worse after switching to the 2D system, especially scores related to technical errors. Conclusions The stereoscopic vision improved laparoscopic surgical techniques of novices from the early phase of training. However, the performance of novices trained only by 3D worsened by changing to the 2D environment.

Abstract
OBJECTIVE To analyze the effect of three-dimensional (3D) laparoscopic total thyroidectomy combined with central lymph node dissection for thyroid cancer and its effect on the inflammatory response of the patients. METHODS The clinical data were analyzed in 90 patients with thyroid cancer undergoing radical thyroidectomy at our hospital between September, 2013 to April, 2016, including 30 receiving 3D laparoscopic surgeries, 30 with 2D laparoscopic surgeries and 30 with open surgeries. The surgical data, postoperative adverse reactions and the impact of the surgeries on the inflammatory responses of the patients were compared among the 3 groups. RESULTS Compared with the open surgery and 2D laparoscopic surgery, 3D laparoscopic surgery was associated with lowered blood loss during the surgery and a lowered incidence of adverse reactions. The operation time in 3D group was significantly shorter than that in 2D group (P<0.05), but the total hospitalization expenses were similar between the two groups. The postoperative drainage volume did not differ significantly between the 3D group and the other two groups. The postoperative hospital stay, number of lymph nodes dissected, positivity rate of lymph nodes and the inflammatory response showed no significant differences among the 3 groups (P>0.05). CONCLUSION 3D laparoscopic total thyroidectomy combined with central lymph node dissection is safe and effective and reduces intraoperative blood loss and perioperative adverse reactions without significant influence on inflammatory response in patients with thyroid cancer.

Abstract
INTRODUCTION This research investigated differences in the effects of a state-of-art stereoscopic 3-dimensional (3D) display and a traditional 2-dimensional (2D) display in simulated laparoscopic surgery over a longer duration than in previous publications and studied the learning effects of the 2 display systems on novices. METHODS A randomized experiment with 2 factors, image dimensions and image sequence, was conducted to investigate differences in the mean movement time, the mean error frequency, NASA-TLX cognitive workload, and visual fatigue in pegboard and circle-tracing tasks. RESULTS The stereoscopic 3D display had advantages in mean movement time ( P < .001 and P = .002) and mean error frequency ( P = .010 and P = .008) in both the tasks. There were no significant differences in the objective visual fatigue ( P = .729 and P = .422) and in the NASA-TLX ( P = .605 and P = .937) cognitive workload between the 3D and the 2D displays on both the tasks. For the learning effect, participants who used the stereoscopic 3D display first had shorter mean movement time in the 2D display environment on both the pegboard ( P = .011) and the circle-tracing ( P = .017) tasks. CONCLUSIONS The results of this research suggest that a stereoscopic system would not result in higher objective visual fatigue and cognitive workload than a 2D system, and it might reduce the performance time and increase the precision of surgical operations. In addition, learning efficiency of the stereoscopic system on the novices in this study demonstrated its value for training and education in laparoscopic surgery.

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.

Abstract
Background During laparoscopy, the surgeon’s loss of depth perception and spatial orientation is problematic. Laser visual guidance (LVG) is an innovative technology that improves depth perception to enhance the visual field. In this trial, we examined the effect of LVG on surgical novices’ motor skills, quality of task performance, and cognitive workload. Methods We designed a randomized controlled trial following the CONSORT statement. Thirty-two surgical novices completed the Training and Assessment of Basic Laparoscopic Techniques (TABLT) test. The first attempt allowed participants to familiarize themselves with the exercises. We then randomized the participants, and they completed a test session using either LVG or conventional two-dimensional vision. Results We found no significant difference between using the LVG tool and conventional 2D vision; however, both the mean completion time and movements used were less in the LVG group: Mean time used in the LVG group was 1288 s (95 % CI 1188–1388) versus 1354 s (95 % CI 1190–1518) (p = 0.45); mean angular path length used in the LVG group was 24,049° (95 % CI 20,761–27,336) versus 26,014° (95 % CI 22,059–29,970) (p = 0.42); mean path length in the LVG group was 4560 cm (95 % CI 3971–5,149 cm) versus 5062 cm (95 % CI 4328–5797), (p = 0.26). Moreover, the mean TABLT performance score was higher in the LVG group compared with the 2D group, although not significant: 379 (95 % CI 352–405) versus 338 (95 % CI 288–387) (p = 0.14). No significant difference was found between the groups’ cognitive workloads. Conclusion We found no significant improvement of laparoscopic motor skills when using LVG, although a tendency toward improved performance was seen. LVG could have the potential to help novice surgeons acquire basic laparoscopic; however, further development of the concept and validation is needed to confirm this.

Abstract
OBJECTIVE To describe studies evaluating 3 generations of three-dimensional (3D) displays over the course of 20 years. SUMMARY BACKGROUND DATA Most previous studies have analyzed performance differences during 3D and two-dimensional (2D) laparoscopy without using appropriate controls that equated conditions in all respects except for 3D or 2D viewing. METHODS Databases search consisted of MEDLINE and PubMed. The reference lists for all relevant articles were also reviewed for additional articles. The search strategy employed the use of keywords "3D," "Laparoscopic," "Laparoscopy," "Performance," "Education," "Learning," and "Surgery" in appropriate combinations. RESULTS Our current understanding of the performance metrics between 3D and 2D laparoscopy is mostly from the research with flawed study designs. This review has been written in a qualitative style to explain in detail how prior research has underestimated the potential benefit of 3D displays and the improvements that must be made in future experiments comparing 3D and 2D displays to better determine any advantage of using one display or the other. CONCLUSIONS Individual laparoscopic performance in 3D may be affected by a multitude of factors. It is crucial for studies to measure participant stereoscopic ability, control for system crosstalk, and use validated measures of performance.
