Abstract
Objective: We present the applications and experiences of robot-assisted laparoscopic and thoracoscopic surgery (RALTS) in pediatric surgery. Materials and Methods: A prospective, observational, and longitudinal study was conducted from March 2015 to March 2018 that involved a non-random sample of a pediatric population that was treated with RALTS. The parameters examined were: gender, age, weight, height, diagnoses, surgical technique, elapsed time of console surgery, estimated bleeding, need for hemotransfusion, complications, surgical conversions, postoperative hospital stay, and follow-up. The Clavien-Dindo classification of complications was used. The surgical system used was the da Vinci model, Si version (Intuitive Surgical, Inc., Sunnyvale, CA. U.S.A), with measures of central tendency. Results: In a 36-months period, 186 RALTS cases were performed, in 147 pediatric patients and an adult; 53.23% were male, and the remaining were female. The average age was 83 months, ranging from 3.5 to 204 months, plus one adult patient of 63 years. The stature was an average of 116.6 cm, with a range of 55-185 cm; the average weight was 26.9 kg, with a range of 5-102 kg; the smallest patient at 3.5 months was 55 cm in stature and weighed 5.5 kg. We performed 41 different surgical techniques, grouped in 4 areas: urological 91, gastrointestinal and hepatobiliary (GI-HB) 84, thoracic 6, and oncological 5. The console surgery time was 137.2 min on average, ranging from 10 to 780 min. Surgeon 1 performed 154 operations (82.8%), and the remainder were performed by Surgeon 2, with a conversion rate of 3.76%. The most commonly performed surgeries were: pyeloplasty, fundoplication, diaphragmatic plication, and removal of benign tumors, by area. Hemotransfusion was performed for 4.83%, and complications occurred in 2.68%. The average postoperative stay was 2.58 days, and the average follow-up was 23.5 months. The results of the 4 areas were analyzed in detail. Conclusion: RALTS is safe and effective in children. An enormous variety of surgeries can be safely performed, including complex hepatobiliary, and thoracic surgery in small children. There are few published prospective series describing RALTS in the pediatric population, and most only describe urological surgery. It is important to offer children the advantages and safety of minimal invasion with robotic assistance; however, this procedure has only been slowly accepted and utilized for children. It is possible to implement a robust program of pediatric robotic surgery where multiple procedures are performed.

Abstract
Despite increasing popularity of minimal-invasive techniques in the pediatric
population, their use in diagnosis and management of pediatric malignancy is still
debated. Moreover, there is limited evidence to clarify this controversy due to low
incidence of each individual type of pediatric tumor, huge diversity of the disease
entity, heterogeneity of surgical technique, and lack of well-designed studies on
pediatric oncologic minimal-invasive surgery. However, a rapid development of medical
instruments and technologies accelerated the current trend toward less invasive
surgery, including oncologic endosurgery. The aim of this article is to review
current literatures about the application of the minimal-invasive approach for
pediatric tumors and to give an overview of the current status, indications,
individual techniques, and future perspectives.

Abstract
The use of minimally invasive surgery (MIS) in pediatric patients has been steadily increasing in recent years. However, its use for diagnosing and treating abdominal tumors in children is still limited compared with adults, especially when malignancy is a matter of debate. Here, we describe the experience at our center with pediatric abdominal tumors to show the safety and feasibility of MIS.Based on a retrospective review of patient records, we selected for study those pediatric patients who had undergone diagnostic exploration or curative resection for abdominal tumors at a single center from January 2010 through August 2015.Diagnostic exploration for abdominal tumors was performed in 32 cases and curative resection in 173 cases (205 operations). MIS was performed in 11 cases of diagnostic exploration (34.4%) and 38 cases of curative resection (21.9%). The mean age of the children who underwent MIS was 6.09 ± 5.2 years. With regard to diagnostic exploration, patient characteristics and surgical outcomes were found to be similar for MIS and open surgery. With regard to curative resection, however, the mean age was significantly lower among the patients who underwent open surgery (4.21 ± 4.20 vs 6.02 ± 4.99 for MIS, P = 0.047), and the proportion of malignancies was significantly higher (80% vs 39.4% for MIS, P < 0.001). MIS compared favorably with open surgery with respect to the rate of recurrence (6.7% vs 35.1%, P = 0.035), the rate of intraoperative transfusions (34.2% vs 58.5%, P = 0.01), the median amount of blood transfused (14 vs 22 mL/kg, P = 0.001), and the mean number of hospital days (4.66 ± 2.36 vs 7.21 ± 5.09, P < 0.001). Complication rates did not differ significantly between the MIS and open surgery groups. The operation was converted to open surgery in 3 cases (27.2%) of diagnostic MIS and in 5 cases (13.1%) of curative MIS.MIS was found to be both feasible and effective for the diagnosis and curative treatment of pediatric abdominal tumors. However, to determine the surgical role and guidelines for MIS for each specific tumor, a multicenter prospective study with a long-term follow-up is warranted.

Abstract
Minimally invasive surgery (MIS) in the management of malignant and benign renal tumours in children is gradually becoming more common. Experience is limited and restricted to case reports, retrospective chart reviews and a few cohort studies. There are currently no randomized controlled trials or controlled clinical trials comparing the laparoscopic and open surgical approach for the management of renal tumours in children. MIS may offer the same oncologic outcome in malignant renal tumours whilst providing the advantages associated with MIS in correctly selected cases. The technique for tumour resection has been shown to be feasible in regards to the recommended oncologic principles, although lymph node sampling can be inadequate in some cases. Preliminary reports do not show an increased risk of tumour rupture or inferior oncologic outcomes after MIS. However, the sample size remains small and duration of follow-up inadequate to draw any firm conclusions. Implementation of MIS is lacking in the protocols of the major study groups, and standardized recommendations for the indications and contra-indications remain undefined. The objective of this article is to present a review of the literature on the role of MIS in the management of renal tumours in children, with the main focus on Wilms' tumour (WT). Further studies on MIS in renal tumours are required to evaluate the incidence of oncological complications such as complete tumour resection and intra-operative tumour spillage. A long-term follow-up of patients managed by MIS is essential to compare recurrence rates and overall survival rates.

Abstract
Minimally invasive surgery has become widely recognized and is commonly used for the diagnosis and treatment of neuroblastoma. However, in post-chemotherapy status or during reoperations, it is occasionally difficult to precisely locate small neuroblastoma lesions, and this becomes prominent in endoscopic surgeries, in which tactile sense is essentially lost. Herein, we report our preliminary experience in two abdominal neuroblastoma cases undergoing laparoscopic tumor resection with aid of intraoperative (123)I- metaiodobenzylguanidine (MIBG) radioguidance using a specifically designed gamma-probe. The procedure enables easier localization of viable neuroblastoma tissue, provided that the tumor shows moderate to high MIBG uptake.

Abstract
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.

Abstract
AIM To present an overall experience of endoscopic operations in children with neurogenic tumors in two medical institutions. MATERIAL AND METHODS Thoracoscopic excision of tumors was performed in 19 children aged 1 month-7.5 years (mean 1.5 years) in two clinics for the period 2010-2014. In 9 children (47.3%) age did not exceed 1 year. In our study ganglioneuroma was diagnosed in 9 cases, ganglioneuroblastoma--in 2 patients, neuroblastoma stage I--in 8 cases. All patients were under observation and treated according to NB2004 protocol. Tumor's diameter ranged from 1 to 6 cm (mean 4.9±1.9 cm). Mean duration of surgery was 62±22 minutes. There were no any intraoperative complications. Early postoperative period in all patients after endoscopic surgery was more favorable than in those after open operations. Any local recurrences were not observed for the follow-up period. RESULTS Thoracoscopic operations can become more preferable method in treatment of children with neurogenic tumors if great vessels are not involved into neoplastic process and limited volume of tumor is absent.

Abstract
The application of minimally invasive surgical techniques to pediatric abdominal tumors is a controversial application towards the surgical management of childhood cancer. Although general pediatric surgeons practice minimally invasive surgery techniques in a vast array of abdominal cases, its role in pediatric oncology is still developing, with no consensus in North America about its use for pediatric solid abdominal tumors. The purposes of this article are to review the current literature about the use of minimally invasive surgery in pediatric abdominal oncology and to examine established indications, procedures and technologic advances.

Abstract
OBJECTIVE The aim was to report a multicentric study with a longer follow-up to evaluate the laparoscopic radical nephrectomy in children with renal cancer. MATERIAL AND METHODS This was a retrospective multicentric study, from October 2005 to January 2012, of children who underwent a laparoscopic radical nephrectomy for small renal malignant tumors. RESULTS Seventeen children were included in this study. Sixteen underwent chemotherapy before surgery according the SIOP (Société Internationale d'Oncologie Pédiatrique) protocol and one was treated by surgery only for a carcinoma. All except one could be treated by laparoscopy; the biggest tumoral size was 8 cm. The median hospital stay was 3 days (2-10). The pathologic examination showed 15 Wilms' tumors, one clear cell sarcoma and one TFE3 renal cell carcinoma. With a median follow-up of 42 months (range 12 and 77 months) after laparoscopic radical nephrectomy, 15 children had no oncological complications (port site or local recurrence, pulmonary metastasis) and one had a local recurrence without intraoperative tumoral rupture. The child with TFE3 renal cell carcinoma died 4 years after surgery from brain and lung metastases without local recurrence. No small bowel obstruction occurred. CONCLUSIONS Radical nephrectomy in children for Wilms' tumor or other renal cancer can be safely performed laparoscopically and our indications can be summarized, for trained laparoscopic surgeons, by small tumors under about 8 cm diameter, especially without crossing the lateral edge of the vertebra on the CT scan at the time of surgery.

Abstract
BACKGROUND Over the last 20 years MIS has progressively gained popularity in children with cancer. We therefore aimed at evaluating the safety of Minimally Invasive Surgery (MIS) resection in a series of children affected by adrenal neuroblastoma (NB) presenting without Image-Defined Risk Factors (IDRFs). METHODS An Institutional protocol for MIS resection of adrenal NB in pediatric patients without IDRFs has been applied since 2008. Absence of IDRFs represented the main indication for MIS in NB, regardless of tumor size. All pediatric patients who underwent MIS for NB between January 2008 and May 2013 were included. Specific technical considerations, demographic data, and outcome have been recorded. RESULTS Twenty-one patients underwent MIS resection for IDRFs-negative adrenal NB. Nine of these patients experienced preoperative downgrading of IDRFs after chemotherapy. Radiological median diameter of the mass was 30 mm (range 10-83 mm). Median operative time was 90 min. Median hospital stay was 4 days. All patients were treated successfully, without serious intraoperative complications. One mild intraoperative hemorrhage occurred and was treated without the need for conversion to open surgery nor blood transfusion was required. No postoperative complications, including port-site or peritoneal metastases were experienced. CONCLUSIONS This study demonstrated the safety and effectiveness of MIS for the resection of adrenal NB without IDRFs in children. Pediatric surgeons dedicated to oncology should be aware of this alternative approach to open resection.

Abstract
Minimally invasive surgery (MIS) for nephrectomy has been described since the early 1990s. More recently, MIS has been used for nephron-sparing surgery (NSS) when treating benign conditions. However, reports of NSS using MIS for malignant conditions are sparse. In this report, we describe our retroperitoneal laparoscopic approach for NSS for a localized Wilms tumor.

Abstract
PURPOSE The purpose of the study was to develop a prediction rule regarding the factors that most accurately predict the diagnosis of a malignancy in a lung nodule in the pediatric oncology patient. METHODS A retrospective review of pediatric oncology patients that underwent lung nodule resection between 1998 and 2007 was performed. Multivariable logistic regression was used to create a prediction rule. RESULTS Fifty pediatric oncology patients underwent 21 thoracotomies and 48 thoracoscopies to resect discrete lung nodules seen on computed tomographic scans during workup for metastasis or routine surveillance. The mean nodule size was 10.43 ± 7.08 mm. The most significant predictors of malignancy in a nodule were peripheral location (odds ratio [OR], 9.1); size between 5 and 10 mm (OR, 2.78); location within the right lower lobe (OR, 2.43); and patients with osteosarcoma (OR, 10.8), Ewing sarcoma (OR, 3.05), or hepatocellular carcinoma (OR, 2.38). CONCLUSIONS Lesions that are between 5 and 10 mm in size and peripherally located in patients with osteosarcoma, Ewing sarcoma, or hepatocellular carcinoma are most likely to be malignant. Use of a prediction rule can help guide clinical practice by determining which patients should undergo surgical resection of lung nodules and which patients may be closely observed with continued radiologic studies.

Abstract
The treatment of prostatic rhabdomyosarcoma (RMS) depends on tumour stratification based on site and histology. An increasing range of cytogenetic, molecular, and immunohistochemistry studies are required. This is difficult to achieve using standard cystoscopic biopsies alone. We present a 5-year-old male, diagnosed with a prostatic RMS. He underwent cystoscopy to confirm the diagnosis and at the same time tissue was obtained for histology using laparoscopic graspers via a STEP Port inserted percutaneously into the apex of his bladder. Histology and cytogenetics confirmed an embryonal botryoid RMS for which he received chemotherapy followed by a radical prostatectomy for residual disease.
