Clin Otolaryngol 2024; 49:538-551. [PMID: 38735751 DOI: 10.1111/coa.14171] [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: 07/11/2023] [Revised: 03/24/2024] [Accepted: 04/20/2024] [Indexed: 05/14/2024]
Abstract
OBJECTIVE Three-dimensional (3D) endoscopy has been developed to provide depth perception to allow for improved visualisation during otolaryngology surgery. We conducted a systematic review to determine the surgical safety and efficacy of 3D endoscopy in comparison to two-dimensional (2D) endoscopy in performing otolaryngology procedures, and the role of 3D endoscopy as a training tool for novice otolaryngology surgeons. METHODS Primary studies were identified through MEDLINE, Embase and Web of Science databases, which were searched for articles published through June 2022 that compared the outcomes of 2D and 3D endoscopy in otolaryngology surgical procedures or otolaryngology-relevant simulations. Candidate articles were independently reviewed by two authors. RESULTS A total of 18 full-text articles met inclusion criteria for this study. In clinical trials (n = 8 studies, 362 subjects), there were no significant differences in performance time, intraoperative or postoperative complications with 3D endoscopes when compared to 2D. In simulation studies (n = 10 studies, 336 participants), 3D endoscopes demonstrated a decreased error rate (n = 5 studies) and shorter performance time (n = 3 studies). Studies also reported improved depth perception (n = 14 studies) and visualisation preference (n = 5 studies) with 3D over 2D systems. The 3D systems were found to have a shorter learning curve and better manoeuvrability among novice surgeons. CONCLUSION 3D endoscopy showed equivalent safety and efficacy compared to 2D endoscopy in otolaryngology surgery. The improved depth perception and performance for novices using 3D endoscopes suggests the technology may be superior to 2D endoscopes as a training tool for otolaryngology surgeons.

Eur J Obstet Gynecol Reprod Biol 2024; 298:187-191. [PMID: 38781785 DOI: 10.1016/j.ejogrb.2024.05.017] [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: 08/30/2023] [Revised: 04/22/2024] [Accepted: 05/15/2024] [Indexed: 05/25/2024]
Abstract
OBJECTIVE Our aim was to evaluate possible short and long-term benefits of 3-dimensional (3-D) compared to 2-dimensional (2-D) laparoscopy for benign hysterectomy. Primary outcomes were long-term quality of life and postoperative pain. Secondary outcomes were operative time, surgical complications, time to return to work and length of hospitalization. STUDY DESIGN A randomized controlled trial conducted at two Danish university hospitals. In each arm, 190 patients were needed for an alpha of 3.3 % and a power of 90 %. For various reasons, however, the study was prematurely terminated after including 97 patients. Patients were randomized to either 2-D (n = 48) or 3-D (n = 49) laparoscopy. A laparoscopic hysterectomy was performed. Quality of life was assessed by the Short Form Health Survey 36 (SF-36) questionnaire at the time of inclusion and 6 weeks postoperatively. Postoperative pain was assessed using a Numeric Rating Scale (NRS) and by monitoring the amount of analgesic consumption. RESULTS Out of the 97 randomized patients, 77 patients completed both SF-36 questionnaires. No significant differences in mental (p = 0.5) and physical status (p = 0.9) were found. The 2-D group had significantly higher pain-score registered in the post anesthesia care unit (PACU) (p = 0.004) and higher consumption of oral morphine equivalent dose (MEqD) (p = 0.003) than the 3-D group. This regardless a higher rate of minilaparotomies in the 2D (n = 7) than in the 3D (n = 1) group (p < 0.03). The 2-D group had also higher rate of Clavien-Dindo 2 (CD2) (n = 2) and Clavien-Dindo 3 (CD3) complications (n = 3) (p = 0.03) than 3-D (n = 0). The other secondary outcome parameters did not vary between groups. CONCLUSIONS The results are severely hampered by the premature termination of the study, as less than 25 percent of the patients were recruited. Thus, no firm conclusions can be drawn regarding the quality of life and many of the secondary outcomes, as the lack of difference may be attributed to a type 2 error. However, the significant differences in postoperative pain and in complication rates suggest a greater advantage of 3-D laparoscopy than originally expected. Despite the methodological problems, the current data deserve attention in a sparsely investigated field, emphasizing the urgent need for further studies.

Abstract
BACKGROUND There are several types of benign renal diseases, such as urological stones, ureteropelvic junction obstruction, renal vascular disease, and inflammation, which are responsible for nonfunctioning kidneys. Laparoscopic nephrectomy (LN) is the gold standard for treating nonfunctioning kidneys with complications. This study presents the results of our initial experiences with 3D laparoscopic nephrectomy (3D-LN) for benign, nonfunctioning kidneys. METHODS From July 2021 to July 2023, 40 consecutive patients who underwent 3D transperitoneal laparoscopic nephrectomy were retrospectively evaluated at the Department of Urology and Department of General Surgery, Hue Central Hospital, Hue, Vietnam. Patient demographics, intraoperative and early postoperative results, postoperative recovery, complications, and three-month follow-up results were recorded. RESULTS The mean age was 58.35 ± 14.9 years. There were 13 (32.5%) male and 27 (67.5%) female patients. Flank pain was the main reason for hospitalization in 33 cases (82.5%); the common cause of a nonfunctioning kidney was urological stones (62.5%). Twenty-three out of 40 patients underwent a left nephrectomy. The average operative time was 92.57 ± 28.69 minutes. A statistically significant difference in surgery time was found between the group with no adhesion and the group with mild adhesion, as well as between the first 19 patients and the last 18 patients (p <0.05). The mean blood loss was 51.62 ± 24.35 ml. Three cases were converted to open surgery due to severe adhesions. The postoperative complications rate was 8.1%. The average length of the postoperative hospital stay was 7.89 ± 3.59 days. CONCLUSIONS Three-dimensional laparoscopic nephrectomy is a safe and effective method that increases depth perception and spatial orientation for surgeons and can compensate for the remaining shortcomings of traditional 2D systems.

Abstract
OBJECTIVE To assess the feasibility and safety of three-dimensional (3D) laparoscopic nephrectomy in combination with bench surgery and autotransplantation for treating highly complex renal tumors. MATERIALS AND METHODS The clinical data of six patients with highly complex renal cell carcinoma were collected. All patients underwent 3D laparoscopic nephrectomy in combination with bench surgery and autotransplantation by the same surgeons, two of them had previously undergone laparoscopic partial nephrectomy for contralateral renal cancer. RESULTS The total operative time was 366 ± 65 min, the warm ischemia time (WIT) was 1.3 ± 0.4 min, and the cold ischemia time was 121 ± 26 min. While one patient received a diluted autologous blood transfusion, the intraoperative blood loss was 217 ± 194 ml. No increase in the serum creatinine (SCr) level was observed at postoperative day 30 compared with the preoperative time, and none of the patients received dialysis either during the hospital stay or to date. Although one patient underwent nephrectomy due to tumor recurrence in the transplanted kidney, the others reported no tumor recurrence or distant metastases on imaging to date. CONCLUSION 3D laparoscopic nephrectomy, when combined with bench surgery and autotransplantation, can become a feasible option for treating highly complex renal cell carcinoma cases when expecting to preserve renal function maximally.

Abstract
Stereopsis may be an advantage of robotic surgery. Perceived robotic ergonomic advantages in visualisation include better exposure, three-dimensional vision, surgeon camera control, and line of sight screen location. Other ergonomic factors relating to visualisation include stereo-acuity, vergence-accommodation mismatch, visual-perception mismatch, visual-vestibular mismatch, visuospatial ability, visual fatigue, and visual feedback to compensate for lack of haptic feedback. Visual fatigue symptoms may be related to dry eye or accommodative/binocular vision stress. Digital eye strain can be measured by questionnaires and objective tests. Management options include treatment of dry eye, correction of refractive error, and management of accommodation and vergence anomalies. Experienced robotic surgeons can use visual cues like tissue deformation and surgical tool information as surrogates for haptic feedback.

Abstract
During minimal invasive surgery (MIS), the laparoscope only provides a single viewpoint to the surgeon, leaving a lack of 3D perception. Many works have been proposed to obtain depth and 3D reconstruction by designing a new optical structure or by depending on the camera pose and image sequences. Most of these works modify the structure of the conventional laparoscopes and cannot provide 3D reconstruction of different magnification views. In this study, we propose a laparoscopic system based on double liquid lenses, which provide doctors with variable magnification rates, near observation, and real-time monocular 3D reconstruction. Our system composes of an optical structure that can obtain auto magnification change and autofocus without any physically moving element, and a deep learning network based on the Depth from Defocus (DFD) method, trained to suit inconsistent camera intrinsic situations and estimate depth from images of different focal lengths. The optical structure is portable and can be mounted on conventional laparoscopes. The depth estimation network estimates depth in real-time from monocular images of different focal lengths and magnification rates. Experiments show that our system provides a 0.68-1.44x zoom rate and can estimate depth from different magnification rates at 6fps. Monocular 3D reconstruction reaches at least 6mm accuracy. The system also provides a clear view even under 1mm close working distance. Ex-vivo experiments and implementation on clinical images prove that our system provides doctors with a magnified clear view of the lesion, as well as quick monocular depth perception during laparoscopy, which help surgeons get better detection and size diagnosis of the abdomen during laparoscope surgeries.

Abstract
Abhishek Pandey, MSObjectives The main aim of this study is to present our experience with laparoscopic radical nephrectomy (LRN) and share practical solutions to various surgical challenges and the learning curve we realized. Materials and Methods We retrospectively analyzed our LRN database for relevant demographic, clinical, imaging, operative, and postoperative data, including operative videos. We described various complications, vascular anomalies, intraoperative difficulties, and our improvisations to improve safety and outcomes. Statistical Analysis We evaluated the learning curve, comparing the initial half cases (group 1) against the latter half (group 2), using the chi-squared test for categorical variables and Student's t -test for continuous variables. Results Of the 106 patients included, LRN was successful in 95% ( n = 101), and five cases converted to open surgical approach. The mean tumor size was 7.4 cm, 42% incidentally detected. The cumulative complication rate was 15%, including five main renal vein injuries. Intraoperative difficulties included ureter identification ( n = 6), venous bleed during hilar dissection ( n = 11), double renal arteries ( n = 23), and venous anomalies ( n = 20). Arterial anatomy had 95% concordance with the imaging findings. We describe various trade tricks to perform hilar dissection, identify and control anomalous vasculature, handle venous bleed, confirm arterial control, and improve decisions using imaging, technology, and guidance of a mentor. No statistically significant difference in the learning curve was observed between the study groups. Conclusion With LRN already established as the current standard of care, our description intends to share the trade tricks and inspire novice urologists, who can assimilate training and reproduce good results under proper guidance. The steep learning curve described in the past may not be apparent in the current era of training and technological advancement.

Abstract
In today's medical practice clinicians need to struggle with a huge amount of data to improve the outcomes of the patients. Sometimes one clinician needs to deal with thousands of ultrasound images or hundred papers of laboratory results. To overcome this shortage, computers get in help of human beings and they are educated under the term "artificial intelligence." We were using artificial intelligence in our daily lives (i.e., Google, Netflix, etc.), but applications in medicine are relatively new. In obstetrics and gynecology, artificial intelligence models mostly use ultrasound images for diagnostic purposes but nowadays researchers started to use other medical recordings like non-stress tests or urodynamics study results to develop artificial intelligence applications. Urogynecology is a developing subspecialty of obstetrics and gynecology, and articles about artificial intelligence in urogynecology are limited but in this review, we aimed to increase clinicians' knowledge about this new approach.

Abstract
Over the past 30 years surgical training, including urology training, has changed from the Halstedian apprenticeship-based model to a competency-based one. Simulation-based education (SBE) is an effective, competency-based method for acquiring both technical and non-technical surgical skills and has rapidly become an essential component of urological education. This article introduces the key learning theory underpinning surgical education and SBE, discussing the educational concepts of mastery learning, deliberate practice, feedback, fidelity and assessment. These concepts are fundamental aspects of urological education, thus requiring clinical educators to have a detailed understanding of their impact on learning to assist trainees to acquire surgical skills. The article will then address in detail the current and emerging simulation modalities used in urological education, with specific urological examples provided. These modalities are part-task trainers and 3D-printed models for open surgery, laparoscopic bench and virtual reality trainers, robotic surgery simulation, simulated patients and roleplay, scenario-based simulation, hybrid simulation, distributed simulation and digital simulation. This article will particularly focus on recent advancements in several emerging simulation modalities that are being applied in urology training such as operable 3D-printed models, robotic surgery simulation and online simulation. The implementation of simulation into training programmes and our recommendations for the future direction of urological simulation will also be discussed.

Abstract
Background This is the first report on three-dimensional (3D) laparoscopic donor nephrectomy performed in the Central Asian region and Commonwealth of Independent States countries. This study presents the results of our initial experiences of 3D hand-assisted laparoscopic donor nephrectomy (3D-HALDN) in comparison with the outcomes of two-dimensional hand-assisted laparoscopic donor nephrectomy (2D-HALDN) at a single center. Methods From 2015 to 2019, 19 3D-HALDN and 19 2D-HALDN procedures were performed at the same center by two surgeons. All 38 procedures used identical techniques. Between-group differences were considered statistically significant at P<0.05. Results The baseline characteristics in both groups were statistically comparable (P>0.05). All donors underwent left nephrectomy. Donors who underwent 3D-HALDN had better outcomes than those who underwent 2D-HALDN, as shown by a shorter warm ischemic time (P<0.05), a shorter operative time (P<0.05), and less blood loss (P<0.05). There were no conversions or major complications (according to the Clavien-Dindo classification) in either group. The average drainage duration and postoperative hospitalization were significantly shorter in the 3D-HALDN group (P<0.05). The between-group differences in the mean postoperative creatinine level and glomerular filtration rate were not significant. Conclusions The 3D-HALDN approach is more beneficial than traditional 2D-HALDN by providing a shorter warm ischemic time, less blood loss, and shorter durations of drainage and postoperative hospitalization. Postoperative complications and the functional condition of the kidney in donors in the early and late postoperative periods did not depend on the type of laparoscopic donor nephrectomy.

Abstract
Objectives: To evaluate perioperative and functional outcomes of clampless laparoscopic tumor enucleation for completely endophytic renal tumors with the guide of intraoperative ultrasonography. Methods: We analyzed patients with clinically completely endophytic tumors, renal tumors, who underwent clampless three-dimensional (3D) retroperitoneoscopic laparoscopic tumor enucleation between January 2012 and January 2021. Patients with exophytic tumors were excluded. Intraoperative ultrasonography was used to map out the mass in all surgeries. Results: Overall, 57 patients underwent clampless 3D retroperitoneoscopic laparoscopic tumor enucleation. Mean surgical time was 131 minutes, and mean estimated blood loss was 202 mL. Mean hospital stay was 4.7 days. Major and minor postoperative complications occurred, respectively, in 3 and 10 cases. Only a patient had a positive surgical margin. One-year renal function did not differ from baseline. Conclusion: Our study showed that clampless laparoscopic enucleation guided by laparoscopic ultrasonography ensured satisfactory outcomes for completely intrarenal tumors, with excellent renal function preservation 1 year after surgery.

Abstract
Background: The aim of this study was to compare the efficacy, safety, and the clinical and perioperative outcomes of two-dimensional (2D) and three-dimensional (3D) laparoscopic imaging systems in adult patients undergoing laparoscopic pyeloplasty in our clinics due to ureteropelvic junction (UPJ) obstruction. Methods: A total of 46 adult patients who had undergone laparoscopic pyeloplasty due to UPJ obstruction were included in the study. Cases that had undergone the operation before January 2019 were retrospectively evaluated with the 2D imaging systems. Cases after that date were evaluated by using the 3D imaging systems, and the operative, perioperative, and postoperative findings of these patients were recorded prospectively. Patients who had undergone laparoscopic pyeloplasty were classified into two groups as the "2D group" and the "3D group." To standardize the preoperative findings, the cases that were operated by a single surgeon experienced in both 2D and 3D imaging systems were included in the study. The demographic characteristics and the clinical findings of the patients were compared between the groups. Results: A total of 41 patients were included in the study. The mean age was 27.7 ± 9.17 years. Among the patients, 23 (56.1%) were in the 2D group and 18 (43.9%) were in the 3D group. No statistically significant difference was observed between groups with regard to the demographic characteristics of the patients. According to the perioperative and postoperative findings of the patients, the duration of the operation was significantly shorter in the 3D group. Conclusion: The duration of the operation was significantly reduced in the 3D image-guided laparoscopic pyeloplasty in the treatment of UPJ obstruction of the adult, compared with 2D image-guided operations. The 3D imaging systems provide a better image quality, an important convenience in intraoperative saturation, and low rates of complication in laparoscopic pyeloplasty, and they may be used safely and effectively.

Short-term comparative study of three-dimensional and two-dimensional laparoscopic surgery for total extraperitoneal primary inguinal hernia repair. JOURNAL OF MINIMALLY INVASIVE SURGERY 2021; 24:98-103. [PMID: 35600788 PMCID: PMC8965998 DOI: 10.7602/jmis.2021.24.2.98] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 02/16/2021] [Revised: 04/21/2021] [Accepted: 05/23/2021] [Indexed: 11/18/2022]
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.

Abstract
Objective To discuss the differences in the effectiveness and security for adrenal tumors by posterior retroperitoneoscopic adrenalectomy (PRA) and lateral transperitoneal laparoscopic adrenalectomy (LTA). Methods We systematically searched PubMed, Embase, Scopus database and Cochrane Library, and the date was from above database establishment to November 2020. Stata 16 was used for calculation and statistical analyses. Results Nine studies involving eight hundred patients were included. The following differences were observed in favor of PRA vs LTA: less operative time (MD: -22.5; 95% CI -32.57 to -12.45; P=0.000), Fewer estimated blood loss (MD: -15.17; 95% CI -26.63 to -3.72; P=0.009), lower intensity of postoperative pain (MD: -0.56; 95% CI, -1.05 to -0.07; P=0.026), shorter length of hospital stay (MD: -1.15; 95% CI -1.94 to -0.36; P=0.04). No differences were shown in conversion rate (OR 2.07; 95%CI 0.71 to 6.03; P=0.181) and complications (OR 0.85;95% CI 0.46 to 1.56; P=0.597). Conclusions Posterior retroperitoneoscopic adrenalectomy was clinically superior to lateral transperitoneal laparoscopic adrenalectomy for adrenal tumors in operative time, estimated blood loss, length of hospital stay, and postoperative pain. Only in term of conversion rate and complications, both were similar.

Abstract
Background: Radical prostatectomy (RP) is the first-line treatment modality for prostate cancer and can be performed using retropubic or minimally invasive techniques. New technologies such as the da Vinci robotic system and three-dimensional (3D) laparoscopic imaging system have been developed to overcome the challenges of conventional laparoscopy. This study aimed to compare the perioperative, oncological, and functional outcomes of robot-assisted laparoscopic RP (RALP) and 3D laparoscopic RP (3D LRP). Materials and Methods: The study was approved by the local ethics committee and included 65 patients (38 RALP, 27 3D LRP) who underwent RP with the diagnosis of localized prostate cancer between May 2019 and January 2020. All demographic, clinical, perioperative, pathological, and postoperative variables were recorded. Results: There was no statistically significant difference between the two groups in terms of preoperative patient characteristics. The mean operative times of the RALP and 3D LRP groups were 135.74 ± 11.51 and 165.37 ± 15.86 minutes, respectively, with a statistically significant difference between the two groups (P = .001). The mean estimated blood loss was 237 ± 71 mL in the RALP group and 257 ± 54 mL in the 3D LRP group, with no statistically significant difference between the two groups (P = .236). In the 6 months of follow-up, there was no statistically significant difference between the two groups in terms of biochemical recurrence, continence, and potency. Conclusion: RALP and 3D LRP have similar perioperative, short-term oncological and functional outcomes other than the operative time. There is a need for prospective, randomized studies with larger populations evaluating long-term oncological and functional outcomes.

Abstract
BACKGROUND Studies for 3D-laparoscopic prostatectomy (3D-LRP) learning curve and surgical results are lacking. Combining 3D vision to LRP attenuates differences compared to Robotic assisted laparoscopic prostatectomy (RALP) with similar mini-invasiveness but lower costs. MATERIALS AND METHODS Two hundred consecutive men with localized prostate cancer underwent 3D-LRP at Seinäjoki central hospital between 2013 and 2018. Oncological and functional results were documented. Long-term functional evaluation was done using EPIC-26 survey. Clavien-Dindo classification was used to assess complications during first 3 months. All operations were performed by a single surgeon (M.R.) with no experience of LRP or 3D-LRP. The learning curve was assessed by evaluating urethral anastomosis- and total operative time. Perioperative and postoperative data was collected prospectively during surgery and at subsequent control visits up to minimum of 1 year. RESULTS A plateau in anastomosis time was reached after 30 cases and in operative time after 60 cases. Median operative time was 114 min (78-258 min) and median time for anastomosis was 25 min (11-90 min). Median blood loss was 150 ml (10-800 ml); 93.5% of the patients were discharged within the first 3 days. Clavien-Dindo ≥3a complications occurred in 6.5%. Positive surgical margins occurred in 23%. One-year after the operation, 93.3% had PSA ≤ 0.1; 91.9% of the patients were dry or used one daytime pad. EPIC-26 scores were as follows: Urinary incontinence 79.25 (14.5-100), urinary irritative/obstructive 93.75 (31.25-100), bowel 100 (33.33-100), sexual 36.17 (0-100) and hormonal 95 (37.5-100). CONCLUSION The learning curve for 3D laparoscopic prostatectomy is comparable to RALP, which makes it a cost-effective alternative with comparable oncological and functional results.

Abstract
Aims To examine the safety and feasibility of three-dimensional (3-D) laparoscopic partial nephrectomy for clinically complex renal tumors. Materials and Methods We retrospectively evaluated 76 patients who underwent a 3-D (n = 42; age, 54.6 ± 12.2 years) or two-dimensional (2-D) laparoscopic partial nephrectomy (n = 34; age, 54.8 ± 13.2 years) for renal tumors with RENAL nephrectomy scores of ≥10 points from the same surgical group between January 2017 and April 2020 in Ningbo Urology and Nephrology Hospital. Mean tumor diameter, operation time, warm ischemic time, amount of intraoperative blood loss, postoperative hospitalization time, hospitalization cost, perioperative complication rate, and renal function were compared. Results The operation time (154.6 ± 45.1 min) and warm ischemic time (22.5 ± 6.8 min) in the 3-D laparoscopic group were significantly lower than those in the 2-D laparoscopic group (193.0 ± 59.2 min, p = 0.001 and 28.7 ± 7.8 min, p = 0.0002, respectively). No significant differences in amount of intraoperative blood loss (p = 0.642), length of postoperative hospital stay (p = 0.541), perioperative complication rate (p = 0.860), total hospital cost (p = 0.641), and renal function changes including estimated glomerular filtration rate and serum creatinine (p > 0.05) were found between the two groups. Conclusion Our preliminary experience showed that the 3-D laparoscopic imaging system significantly shortened the operation and renal ischemic times, which are more conducive to partial resection of highly complex renal tumors.

Abstract
OBJECTIVE To compare three-dimensional (3D) with standard two-dimensional (2D) laparoscopic partial nephrectomy (LPN) with respect to intra- and postoperative outcomes. MATERIAL AND METHODS Data from 112 patients who underwent transperitoneal LPN from 2012 to 2014 by a single experienced surgeon were collected. Sixty patients (group 1) underwent conventional 2D LPN and 52 patients (group 2) 3D LPN. Perioperative patient, procedure, and tumor data were recorded. The follow-up period was 1-5 years. RESULTS The two groups had similar patient age (p=0.834) and body mass index (p=0.141). The total laparoscopy time (LT) was shorter in group 2 (119.0 vs. 106.0 min; p=0.009). Warm ischemia times (WITs) were also shorter in group 2 (11.5 vs. 10.0 min; p=0.032). The estimated blood loss (EBL) (350.0 vs. 250.0 mL; p<0.001) and hemoglobin (Hb) decrease (1.55 vs. 1.35 g/dL; p=0.536) were lower in the 3D LPN group. Creatinine (0 vs. 0 g/dL; p=0.610) increase and estimated glomerular filtration rate (eGFR) decrease (0 vs. 0 mL/min/1.73 m2; p=0.553) did not demonstrate statistically significant differences. Duration of hospitalization (7 vs. 7 days; p=0.099) and complication rates (p=0.559) were similar between the two groups. CONCLUSION The new-generation 3D laparoscope has a great impact on significant LPN intraoperative parameters, mainly LT, WIT, and EBL. Hb decrease is also in favor of 3D vision, although not dramatically altered. Therefore, 3D LPN appears to be superior to conventional 2D LPNs.

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
Objective: The objective of this study is to compare the use of three-dimensional (3D) vision systems with traditional two-dimensional systems in laparoscopic urological surgery, analyzing the benefits, limitations, and impact of introducing this medical technology with regard to surgical performance and the surgeon's ergonomics. Methods: A systematic review with a structured bibliographic search was conducted in the electronic libraries (PubMed and EMBASE) until August 2019 and with no language restrictions. Studies on 3D visualization technology in laparoscopic urologic surgery, randomized controlled trials, and observational comparative studies were included. Relevant data were extracted and analyzed. Results: A total of 25 articles were obtained, of which 4 were clinical studies with patients, 2 studies were carried out in experimental animal models, and the remaining 19 were conducted in simulated environments. Regarding the European training program in basic laparoscopic urological skills, the results showed no significant differences in execution time using either imaging system. Three-dimensional vision led to a significant reduction in surgery time in pyeloplasty and radical nephrectomy. In addition, there was a reported decrease in blood loss in adrenalectomy, nephron-sparing nephrectomy, radical nephrectomy, simple nephrectomy, and pyeloplasty using 3D vision. Regarding ergonomics, the studies generally described no differences in side effects (headache, nausea, eye strain) when comparing the two types of visualization systems. Surgeons reported reduced workloads and stress with 3D vision than with traditional laparoscopy. Conclusions: Three-dimensional laparoscopic systems essentially advance surgical performance in less-experienced laparoscopic surgeons. Three-dimensional laparoscopy leads to improvements in surgery time, which is important for specific surgical procedures involving intracorporeal ligatures and sutures. The results achieved on the surgeons' ergonomics showed better depth perception and decreased stress and workloads during 3D vision with no differences in potential side effects.

Abstract
Artificial intelligence (AI) is growing exponentially in various fields, including medicine. This paper reviews the pertinent aspects of AI in obstetrics and gynecology (OB/GYN) and how these can be applied to improve patient outcomes and reduce the healthcare costs and workload for clinicians. Herein, we will address current AI uses in OB/GYN, and the use of AI as a tool to interpret fetal heart rate (FHR) and cardiotocography (CTG) to aid in the detection of preterm labor, pregnancy complications, and review discrepancies in its interpretation between clinicians to reduce maternal and infant morbidity and mortality. AI systems can be used as tools to create algorithms identifying asymptomatic women with short cervical length who are at risk of preterm birth. Additionally, the benefits of using the vast data capacity of AI storage can assist in determining the risk factors for preterm labor using multiomics and extensive genomic data. In the field of gynecological surgery, the use of augmented reality helps surgeons detect vital structures, thus decreasing complications, reducing operative time, and helping surgeons in training to practice in a realistic setting. Using three-dimensional (3D) printers can provide materials that mimic real tissues and also helps trainees to practice on a realistic model. Furthermore, 3D imaging allows better depth perception than its two-dimensional (2D) counterpart, allowing the surgeon to create preoperative plans according to tissue depth and dimensions. Although AI has some limitations, this new technology can improve the prognosis and management of patients, reduce healthcare costs, and help OB/GYN practitioners to reduce their workload and increase their efficiency and accuracy by incorporating AI systems into their daily practice. AI has the potential to guide practitioners in decision-making, reaching a diagnosis, and improving case management. It can reduce healthcare costs by decreasing medical errors and providing more dependable predictions. AI systems can accurately provide information on the large array of patients in clinical settings, although more robust data is required.

Zhao B, Lv W, Mei D, Luo R, Bao S, Huang B, Lin J. Comparison of short-term surgical outcome between 3D and 2D laparoscopy surgery for gastrointestinal cancer: a systematic review and meta-analysis. Langenbecks Arch Surg 2020; 405:1-12. [PMID: 31970475 DOI: 10.1007/s00423-020-01853-8] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2019] [Accepted: 01/09/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Three-dimensional (3D) laparoscopic surgery is becoming more popular with the development of laparoscopic devices. The objective of this study was to explore whether the 3D imaging system could improve surgical outcomes of laparoscopic surgery for gastrointestinal cancer compared with the 2D imaging system. METHODS Systematic literature search was performed using PubMed and Embase databases and relevant data were extracted. Surgical quality, postoperative complications, and postoperative recovery between 3D and 2D laparoscopic surgery groups were compared using a fixed or random effect model. RESULTS A total of 12 studies involving 1456 patients (3D group 683 patients and 2D group 773 patients) were included in this meta-analysis. The results indicated that mean operation time was significantly shorter in 3D group than in 2D group (WMD, - 9.08; 95% CI, - 14.77, - 3.40; P = 0.002; I2 = 70.3%), especially for gastric cancer patients (WMD, - 14.61; 95% CI, - 26.00, - 3.23, P = 0.012; I2 = 74.1%). In addition, 3D laparoscopic surgery for gastric cancer had an advantage than 2D group in reducing the amount of intraoperative blood loss (WMD, - 13.60, 95% CI, - 21.48, - 5.72; P = 0.001; I2 = 0%). The number of retrieved lymph nodes in 3D group was not significantly different from that in 2D group, regardless of laparoscopic gastrectomy (WMD, 1.10; 95% CI, - 0.67, 2.88; P = 0.222; I2 = 18.8%) and laparoscopic colorectal surgery (WMD, 0.55, 95% CI; - 1.99, 3.09; P = 0.671; I2 = 76.9%). In addition, there was no significant difference between 3D and 2D laparoscopic surgery for postoperative complications and postoperative recovery. CONCLUSION Main advantages of 3D laparoscopic gastrectomy for gastric cancer were that it could shorten the operation time and reduce the amount of intraoperative blood loss. However, 3D laparoscopic surgery had no obvious advantage over 2D laparoscopic surgery for colorectal cancer patients.

Three-dimensional versus two-dimensional high-definition laparoscopy in transabdominal preperitoneal inguinal hernia repair: a prospective randomized controlled study. Surg Endosc 2019; 34:4857-4865. [PMID: 31754852 PMCID: PMC7572346 DOI: 10.1007/s00464-019-07266-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2019] [Accepted: 11/12/2019] [Indexed: 12/21/2022]
Abstract
BACKGROUND Three-dimensional (3D) laparoscopy improves technical efficacy in laboratory environment, but evidence for clinical benefit is lacking. The aim of this study was to determine whether the 3D laparoscopy is beneficial in transabdominal preperitoneal laparoscopic inguinal hernia repair (TAPP). METHOD In this prospective, single-blinded, single-center, superior randomized trial, patients scheduled for TAPP were randomly allocated to either 3D or two-dimensional (2D) TAPP laparoscopic approaches. Patients were excluded if secondary operation was planned, the risk of conversion was high, or the surgeon had less than five previous 3D laparoscopic procedures. Patients were operated on by 13 residents and 3 attendings. The primary endpoint was operation time. The study was registered in ClinicalTrials.gov (NCT02367573). RESULTS Total 278 patients were randomized between 5th February 2015 and 23rd October 2017. Median operation time was shorter in the 3D group (56.0 min vs. 68.0 min, p < 0.001). 10 (8%) patients in 3D group and 6 (5%) patients in 2D group had clinically significant complications (Clavien-Dindo 2 or higher) (p = 0.440). Rate of hernia recurrence was similar between groups at 1-year follow-up. In the subgroup analyses, operation time was shorter in 3D laparoscopy among attendings, residents, female surgeons, surgeons with perfect stereovision, surgeons with > 50 3D laparoscopic procedures, surgeons with any experience in TAPP, patients with body mass indices < 30, and bilateral inguinal hernia repairs. CONCLUSION 3D laparoscopy is beneficial and shortens operation time but does not affect safety or long-term outcomes of TAPP.

Abstract
Pyeloplasty is one of the most common urological reconstructive interventions. Since the presentation of the first open pyeloplasty by Anderson and Hynes in 1949, the management of ureteropelvic junction obstruction has dramatically developed. The most immense progress was made in the 1990s with the introduction of laparoscopy. A multitude of new minimal surgical techniques have been introduced since then. In the last few years, the innovations were based on refinement of already-existing techniques and technology. With this aim, single-port surgery, three-dimensional vision for laparoscopy, robotic technology, and alternative techniques for creating the anastomosis-like fibrin glue have been introduced. This unsystematic review is timely, and the scientific interest is to present and discuss some of the latest advances in surgical techniques and different approaches for the intra- and post-operative management in pyeloplasty. To the best of our knowledge, this is the only review looking at the recent advances in urological surgical techniques for pyeloplasty during the last few years with a focus on new technology and surgical techniques.
