Three-dimensional laparoscopy and thoracoscopy in children and adults: A prospective clinical trial

Use of 3D in paediatric minimal access surgery: our experience of 209 cases

AIM

In the last three decades, the field of surgery has evolved from open surgery to an era of minimal access surgery (MAS) which is conventionally 2 dimensional (2D). When the vision is 3 dimensional (3D), which is natural, the accuracy and safety of procedures can be improved and complex reconstructive MAS procedures can be performed with depth perception. The aim was to assess feasibility, safety and efficacy of 3D MAS in the paediatric age group.

METHODS AND MATERIAL

Retrospective analysis of 209 3D MAS procedures in the department of Paediatric Surgery over a period of five years. Subjective rating of image quality and difficulty score was done immediately after each procedure by operating and assistant surgeons. Likert scale was used. All data recorded was analysed and are represented as mean, median or percentage.

RESULTS

The average score for subjective rating of image quality was 9.71 for surgeon and 9.74 for assistant surgeon with some parameters having higher subjective scores for the procedures on infants. It explains advantage of 3 D vision in every aspect of imaging. Mean difficulty scores for surgeon (0.12) and assistant surgeon (0.10) were very low, suggesting encouraging vision for the surgeons.

CONCLUSIONS

The use of 3D in paediatric minimal access surgery is feasible and safe. Advantage of excellent vision with depth perception is unequivocal, which along with the use of conventional hand instruments can be a good alternative to more expensive robotic surgical systems.

Two- and three-dimensional laparoscopic donor nephrectomy: a comparative study of a single-center experience

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.

Video-assisted thoracic surgery sleeve resection and bronchoplasty using 3D imaging system: its safety and efficacy

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.

Comparison of 3D vs 2D laparoscopic-assisted anorectal pull-through (LAARP) for high anorectal malformations in children

INTRODUCTION

The limitation of two-dimensional (2D) laparoscopic techniques includes lack of stereoscopic vision and depth perception which can affect surgical performance, physical and mental comfort of the operating surgeon. 3D laparoscopic surgery is popular in adults; however, its application and experience in the pediatric age group have been limited. We did a comparison of 2D and 3D laparoscopic-assisted anorectal pull-through (LAARP) in male high anorectal malformations (ARM).

MATERIAL AND METHOD

This prospective cohort study included male children diagnosed with high anorectal malformation (recto-prostatic urethral fistula) who underwent LAARP in infancy after a neonatal colostomy between November 2019 to March 2020. The patients were randomized into a 2D group or 3D group at a 1:1 ratio. Patient demographics and operative/postoperative parameters were recorded. The effect of 3D laparoscopy was assessed in terms of laparoscopy visual parameters (image quality, depth perception, hand-eye coordination, and precision), physical discomfort (5-point Likert scale), and mental strain (State-Trait Anxiety Inventory scale). The statistical tests were performed on SPSS version 16.

RESULTS

The demographics of both groups, 20 (patients in each), were similar. There was a significant reduction of laparoscopy execution time, physical discomfort (for eye, hand and wrist strain), and overall mental strain in the 3D group. There were similar complications, blood loss, and hospital stay, and no open conversion in two groups.

CONCLUSION

3D LAARP is feasible and safe in the surgical treatment of ARM in children. Further studies with assessment by more than one observer are needed to investigate the wider application of 3D in pediatric surgery.

Three-dimensional (3D) system versus two-dimensional (2D) system for laparoscopic resection of adrenal tumors: a case-control study

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.

Applicability and Effectiveness of Laparoscopic Procedures in Pediatrics

Background: Three-dimensional (3D) laparoscopic surgery in pediatrics is still uncommon and few studies assessed in clinical practice advantages and disadvantages. Applicability and effectiveness of 3D versus two-dimensional (2D) laparoscopic procedures in congenital and acquired conditions in children are still unknown. We assessed applicability and effectiveness of 3D compared with 2D laparoscopic procedures in a pediatric setting. Methods: Two groups of patients who underwent 3D or 2D laparoscopic surgical procedures between May 2016 and April 2018 were compared. Each 3D/2D laparoscopic procedure was assessed with a surgeon/assistant questionnaire. Results: The 3D group included 30 patients and the 2D group 32 patients. The analysis of the 3D/2D questionnaire showed statistically significant superiority of 3D technical aspects (P = .0000), allowing a better spatial orientation and depth perception, reducing manipulation and trauma to tissues. Moreover, no difference was reported in physical complaints (P = .7084), but decreased visual fatigue was highlighted by surgeon (P = .000). Conclusions: In pediatric patients, 3D laparoscopic procedures prove to be more effective facilitating the surgeon's performance, while maintaining the benefits of minimally invasive surgery.

Does a 3D laparoscopic approach improve surgical outcome of mininvasive right colectomy? A retrospective case-control study

Laparoscopy has gained wide acceptance due its benefits for patients. However, advanced laparoscopic procedures are still challenging. One critical issue is lack of stereoscopic vision. Despite its diffusion, the totally laparoscopic approach for right hemicolectomy (TLRC) is still debated due to its difficulty, particularly for fashioning of the ileocolic anastomosis. The aim of this multicenter study is to investigate whether 3D vision offers any advantages on surgical performance over 2D vision during TLRC. All data of consecutive patients who underwent elective TLRC for cancer at three Italian surgical centers with either 2D or 3D technology from January 2013 to December 2018 were retrieved from a computer-maintained database. A case-matched analysis using the Mantel-Haenszel method was performed. After matching, a total of 106 patients were analyzed with 53 patients in each group. Mean operative time was significantly longer for 2D-TLRC than for 3D-TLRC (153.2 ± 52.4 vs. 131 ± 51 min, p = 0.029) and a statistically significant difference in anastomosing time (p = 0.032, 19.2 ± 5.9 min vs. 21.7 ± 6.2 min for 3D and 2D group, respectively) was also recorded. No difference in the median number of harvested nodes (23 ± 11 vs. 21 ± 7 for 3D and 2D group, respectively; p = 0.48) was found. Neither intraoperative complications nor conversions occurred in the two groups. In conclusion, 3D vision appears to improve the performance of a TLRC by reducing operative time and making intracorporeal anastomosis easier. Prospective randomized studies are required to determine the real beneficial effects.

Totally endoscopic mitral valve repair using a three-dimensional endoscope system: initial clinical experience in Korea

Background

The lack of depth perception is a significant challenge in two-dimensional (2D) video-assisted/directed minimally invasive cardiac surgery (MICS). Accordingly, restoration of stereoscopic vision is potentially beneficial, and we present a single center experience of a three-dimensional (3D) endoscope system in cardiac surgery without robotic assistance.

Methods

We retrospectively reviewed the initial 40 consecutive patients who received totally endoscopic mitral valve (MV) repair using a 3D endoscope system between September 2017 and April 2019. The preoperative characteristics, operative data, and immediate postoperative outcomes, including echocardiographic results, were investigated.

Results

In all the patients (n=40, 100%), successful MV repair using the standard repair techniques was achieved regardless of the location of the MV lesion as follows: anterior leaflet (n=8, 20.0%), posterior leaflet (n=15, 37.5%), and both leaflets (n=17, 42.5%). Concomitant tricuspid ring annuloplasty (n=9, 22.5%) and atrial fibrillation ablation (n=7, 17.5%) were performed. There was no mortality. One reoperation for bleeding occurred. One patient had a sternotomy conversion due to aortic dissection immediately after declamping. Postoperative mitral regurgitation (MR) grades were none or trace in 38 patients (95.0%) and mild in 2 patients (5.0%) on predischarge echocardiography.

Conclusions

Totally endoscopic MV repair using a 3D endoscope system is technically feasible and safe on the basis of this initial experience.

Comparison of Three- and Two-Dimensional Laparoscopy in Pediatric Nissen Fundoplication

Aim: This study aimed to evaluate the usefulness of three-dimensional (3D) versus conventional two-dimensional (2D) vision in pediatric laparoscopic Nissen fundoplication. Materials and Methods: Medical records and procedure videos of patients 18 years old or younger who underwent laparoscopic Nissen fundoplication at a single institution between January 2015 and August 2018 were retrospectively reviewed. The total pneumoperitoneum and wrapping times were measured. The number of errors during the first stitch of the wrapping was counted. Three-dimensional laparoscopy was introduced in January 2017, and data were compared between the previous 2D and current 3D groups. A questionnaire was provided to each surgeon who performed the 3D procedure. Results: Laparoscopic fundoplication was performed under 2D vision in 32 patients and under 3D vision in 19 patients. Mean ages and weights at surgery were similar between the groups. There was no significant differences in pneumoperitoneum and wrapping times between the two groups. Significantly more errors were counted in the 2D versus 3D procedure, but all patients recovered without any complications related to intraoperative errors. On the questionnaires, all 8 surgeons desired a decreased scope diameter and multidirectional visual axis. Four surgeons (50%) experienced eyestrain and 1 experienced double vision. Conclusions: This study showed no reduction in surgical time with 3D versus 2D scope use. Three-dimensional vision decreased the technical errors in creating the wrap, but its clinical merit remains unclear. Decreasing the scope diameter and adding multidirectional vision capabilities are needed for the 3D scope to gain more widespread approval and use in pediatric surgery.

Application of a three-dimensional video system in the training for uniportal thoracoscopic surgery

Background

Three-dimensional (3D) video systems offer better depth perception and are associated with improved performance during endoscopic or robotic surgery. We compared the impact of a 3D video system with a two-dimensional (2D) video system on a simulation program for uniportal thoracoscopic surgery.

Methods

We launched an endoscopic simulation program for uniportal surgery using a 3D high-definition video system for training surgeons and medical students. This program included three basic surgical skills: (I) peg transfer, (II) passing a needle through a 3-mm hole, and (III) suturing on a tailor-made skin model. We evaluated the impact of 3D vision during simulation for uniportal surgery in each task. Overall, 113 trainees (85 surgeons in training and 28 medical students) who had not experienced a 3D video system were registered in the program. The three surgical simulation skills were evaluated under 2D and 3D video systems.

Results

The 3D video system allowed for shorter procedural times [92 participants (80.0%) in task 1, 102 (86.4%) in task 2, and 88 (74.6%) in task 3] and improved performance. Moreover, 65 s in task 1, 145 s in task 2, and 32 s in task 3 were shortened using the 3D video system. Post-simulation survey revealed improved depth perception (n=71, 60.2%) and handling of instruments on the uniportal surgical module (n=39, 33.1%) as advantages of the 3D video system during simulation. Sixty (50.8%) trainees were not negatively affected by the use of the 3D glasses; however, 53 (44.9%) felt eye discomfort during simulation.

Conclusions

We concluded that the 3D video system has potential advantages, such as improved procedure time and handling of instruments, during basic simulation of uniportal surgery for surgical trainees.

How Much Stereoscopic Effect Does Laparoscopy Need? Controlled, Prospective Randomized Trial on Surgical Task Efficiency in Standardized Phantom Tasks

Background. To regain 2-eyed vision in laparoscopy, dual-channeled optics have been introduced. With this optics design, the distance between the 2 front lenses defines how much stereoscopic effect is seen. This study quantifies the impact of an enhanced and a reduced stereo effect on surgical task efficiency. Methods. A prospective single-blinded study was performed with 20 laparoscopic novices in an inanimate experimental setting. A standard bichannelled stereo system was used to perform a suturing and knotting task. The working distance and the task size were scaled to vary the stereo effect and, thereby, simulate hypothetic stereo optics with enhanced and reduced optical bases. The task performances were timed, and the number of trials for stitching out was counted. The participants finally filled out a questionnaire to collect subjective impressions. Results. The increase of the stereo effect by 50% caused no objective improvement in laparoscopic knotting compared with typical 3D (control group with stereo basis of 4.5 mm). But ergonomic disadvantages (headache) were subjectively reported in 1 of 20 cases in the questionnaire. The reduction of the stereo effect by one-third led to a significantly longer average execution time. There was no significant dependence found between stereo effect and number of stich-out trials, stitching precision, or knotting quality. Conclusions. Considering laparoscopy, it does not seem advisable to enhance the stereo effect because of ergonomic problems. Otherwise, a miniaturization of the 3D scope (5 mm version) is problematic because its benefit mostly shrinks with the reduced stereo effect.

2D Versus 3D in Laparoscopic Surgery by Beginners and Experts: A Randomized Controlled Trial on a Pelvitrainer in Objectively Graded Surgical Steps

BACKGROUND AND OBJECTIVE

Progress in endoscopic surgery in the past few decades has led to the application of 3-dimensional (3D) procedures in operating rooms. This permits patient- and surgeon-friendly operations and also maximizes the superiority of laparoscopy over laparotomy. In this study, we compare 2-dimensional (2D) and 3D endoscopy techniques with regard to time, efficiency, optics, and handling by users with different degrees of experience at 4 difficulty levels.

DESIGN

A randomized controlled trial on a pelvitrainer in objectively graded surgical steps for students and postgraduates.

SETTING

The trials took place at the Kiel School of Gynaecological Endoscopy, a training unit of the Kiel University Department of Obstetrics and Gynecology, a tertiary academic medical center.

PARTICIPANTS

The 277 study participants, divided into students, residents, and specialists, worked on pelvitrainers with 2 different optical systems, the 2D full HD and the 3D mode. The following 4 exercises were performed with each optical system: (1) grasping and transferring of pins, (2) cutting predetermined marks, (3) vaginal closure with prevention of prolapse, and (4) sacrocolpopexy. The duration and success of the tasks were measured and compared. A self-assessment questionnaire was completed by the participants.

RESULTS

Overall, the 3D-system permitted a greater improvement in working speed, superior optical visualization, and better endoscopic handling in all groups, independent of surgical experience. All students improved in speed (exercises: 1-3) and made significantly fewer mistakes (exercise 2) on 3D compared with 2D. Residents made progress in time (exercises: 1-4) and task performance (exercise 3). Specialists improved significantly in the more challenging tasks 3 and 4. Subjectively, 68.8% of participants preferred 3D for performing laparoscopy.

CONCLUSION

Systematic training programs on pelvitrainers can improve endoscopic skills not only in beginners but also in experienced surgeons. The 3D system offered distinct advantages over 2D imaging and was well accepted by surgeons.

What Are the Advantages of 3D Cameras in Gynaecological Laparoscopy?

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

The comparison between novel and traditional three-dimensional image system in thoracoscopy: glasses-less vs. glass

BACKGROUND

Although three-dimensional (3D) thoracoscopic technology has been available for some time, it is not widely utilized in most centers. Dimness, unsatisfied visualization and discomfort associated with wearing 3D glasses might account for such phenomenon. We have recently developed a "Glass-less" 3D system for thoracoscopic surgery to avoid these in issues.

METHODS

Surgical residents will be invited to perform a set of commonly used surgical procedures using "Glass-less" 3D and conventional 3D system. The procedure duration will be recorded and analyzed. Besides, they will be asked to finish questionnaires before and after procedure.

RESULTS

A total of 25 volunteers were participated in the study. The mean working time of them was 18.3 years. 3D image system was not routinely used by most of them. High maintenance cost was the major reason for the result (8/25). Most of them showed great expectation of 3D system on ideal visualization and comfortability (19/25, 21/25). Majority of participants preferred glass-less 3D system rather than the conventional one referring to image quality (14/25), effect (13/25), accessibility (17/25) and overall performance (16/25). However, most of them felt uncomfortable when using glass-less 3D (17/25). Regarding to operation precision, 10 of them preferred glass-less 3D while 11 considered no difference. No difference was observed in the comparison of procedure duration.

CONCLUSIONS

Glass-less 3D image system was a novel technology which offered ideal image, similar operational precision as the conventional 3D system. Although inappropriate utilization might lead to discomfort experience, improvements would be acquired after proper adjustments.

[VATS - technique and indications]

Video-assisted thoracoscopic surgery (VATS) has revolutionized the practice of thoracic surgeons and improved patient experiences and outcomes worldwide. The VATS approach has matured over the past decades and now accounts for approximately 50 % of all operations in specialized thoracic surgery units. The VATS procedure is less invasive and therefore allows a faster recovery of patients. Over the last 20 years VATS has developed into a safe and effective technique for the diagnostics and therapy of many thoracic diseases. With increasing experience thoracic surgeons can carry out more advanced and technically challenging interventions. Nowadays, VATS is the superior technique in many cases of thoracotomy.

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

BACKGROUND

Laparoscopic surgery is widely used, and results in accelerated patient recovery time and hospital stay were compared with laparotomy. However, laparoscopic surgery is more challenging compared with open surgery, in part because surgeons must operate in a three-dimensional (3D) space through a two-dimensional (2D) projection on a monitor, which results in loss of depth perception. To counter this problem, 3D imaging for laparoscopy was developed. A systematic review of the literature was performed to assess the effect of 3D laparoscopy.

METHODS

A systematic search of the literature was conducted to identify randomized controlled trials that compared 3D with 2D laparoscopy. The search was accomplished in accordance with the PRISMA guidelines using the PubMed, EMBASE, and The Cochrane Library electronic databases. No language or year of publication restrictions was applied. Data extracted were cohort size and characteristics, skill trained or operation performed, instrument used, outcome measures, and conclusions. Two independent authors performed the search and data extraction.

RESULTS

Three hundred and forty articles were screened for eligibility, and 31 RCTs were included in the review. Three trials were carried out in a clinical setting, and 28 trials used a simulated setting. Time was used as an outcome measure in all of the trials, and number of errors was used in 19 out of 31 trials. Twenty-two out of 31 trials (71%) showed a reduction in performance time, and 12 out of 19 (63%) showed a significant reduction in error when using 3D compared to 2D.

CONCLUSIONS

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

The role of minimally invasive surgery in pediatric solid tumors

During recent years, minimally invasive surgery (MIS) has become the standard approach for various operations in infants and children. MIS in pediatric thoracic and abdominal tumors is a controversial approach in the surgical management of childhood cancer. Meanwhile, more and more oncological biopsies and resections are being performed laparoscopically or thoracoscopically. Despite its increasing role in pediatric tumor surgery, the different national and international multicenter trial groups have not yet implemented MIS within guidelines and recommendations in most of the current treatment protocols. An increasing number of retrospective reports describes a potential role of MIS in the management of different pediatric oncological entities. Over the time, there has been a diverse development of this approach with regard to the different neoplasms. Nevertheless, there is a lack of prospective randomized trails assessing MIS. This still represents a requirement for evidence-based medicine and judging the advantages and disadvantages of this approach. The purpose of this state-of-the-art article is to review the current literature to describe the application of MIS in pediatric solid tumors.
