Collaborating with our adult colleagues: A case series of robotic surgery for suspicious and cancerous lesions in children and young adults performed in a free-standing children's hospital

Status of robotic surgery in pediatric genitourinary tumors: A systematic review

Innovative surgical approaches are crucial in pediatric oncology to enhance treatment outcomes and minimize morbidity. Robotic-assisted surgery (RAS) has shown promise in both surgical precision and recovery in pediatric patients. This systematic review aims to address this gap by examining the current role and impact of RAS in managing pediatric genitourinary tumors, focusing on its feasibility, safety, and patient outcomes. This review was registered with PROSPERO (CRD42023464820). We included studies involving pediatric patients undergoing RAS for genitourinary tumors, focusing on outcomes like conversion rates, resection completeness, and complications. Studies were identified through searches in PubMed, EMBASE, and Scopus until October 2023. Study quality and bias were assessed using ROBINS-I for cohort studies and Joanna Briggs Institute tools for case reports and series. Of 2119 citations, 42 studies were included, comprising 29 case reports, five case series, and eight retrospective cohort studies. Robotic-assisted renal surgeries were most common, with favorable outcomes in terms of resection completeness and low recurrence rates. Adrenal, bladder, and retroperitoneal surgeries also showed promising results, although rare instances required conversion to open surgery. Collaborative efforts and perioperative aids like intraoperative ultrasound and three-dimensional modeling were crucial for success. This work is limited by the lack of large cohort studies and addressing the learning curve associated with these procedures. RAS shows promise in treating pediatric genitourinary tumors, offering precise resections and favorable outcomes, warranting further research and refinement.

Perioperative and oncologic outcomes of robotic surgery for pediatric solid abdominal tumors: a single-center 10-year experience

Introduction

Minimally invasive surgery (MIS) has revolutionized oncological surgery with benefits such as smaller incisions and quicker recovery. However, its use in pediatric population is debated due to concerns about complete tumor resection and complications. Robotic surgery, offering enhanced visualization and precision, may address these issues. This study reviews a decade of robotic surgery for pediatric solid abdominal tumors at a single center, assessing perioperative and oncological outcomes.

Methods

This prospective, single-arm study involved patients aged over six months, treated between 2013 and 2023 for solid abdominal tumors. Exclusion criteria included weight <6 kg, distant metastasis, and tumors >6 cm in shortest diameter. All patients underwent thorough preoperative assessment, including imaging and multidisciplinary evaluation. Surgeries were performed using the da Vinci Si Surgical System and data on patient demographics, perioperative outcomes, and follow-up were systematically collected.

Results

The study cohort included 20 patients (9 boys and 11 girls) with a median age of 3.5 years. The median operative time was 114 min, with a median hospital stay of 3 days. Conversion to open surgery was necessary in 10% of cases. R0 resection was achieved in all cases, with a satisfactory lymph node sampling. Median follow-up of 5 years showed overall survival and event-free survival rates of 90%.

Conclusion

Robotic surgery for pediatric abdominal tumors is safe and effective, reducing blood loss and hospital stays without compromising oncological outcomes. Proper case selection and adherence to oncological principles are essential. Further multicenter studies are needed to validate these findings and optimize the use of robotic surgery in pediatric oncology.

Robotic Surgery in Paediatric Oncology: Expanding Boundaries and Defining Relevant Indications

This article reviews the establishment and progress of the Multidisciplinary Paediatric Robotic Program in a high-volume paediatric surgery department at Hôpital Necker-Enfants Malades, Paris, France. A major foundational principle of the program was to establish a safe and secure environment for patients and staff, both pre-operatively, intra-operatively and post-operatively. This founding principle when applied systematically has allowed increasing confidence across the program and service. The robotic platform allows for precision surgery when approaching tumours, with freedom of movement adapted to meticulous vascular and organ dissection. Surgical feasibility is based on tumour characteristics, pre-operative imaging, with a focus on vascular and organ involvement, considering goals of surgery and surgical experience. Case complexity has been gradually increased (where appropriate) through an iterative process. The future of surgery is robotic, and even more so image-guided surgery, and this synergy has been instrumental when approaching tumour surgery in children. The current principles that guide application of robot-assisted surgery in paediatric tumours are presented. With this blueprint, excellent oncological outcomes can be achieved while utilising a minimally invasive approach in children with selected endocrine, neuroblastic and renal tumours.

Robotic retroperitoneal lymph node dissection for paratesticular rhabdomyosarcoma in adolescents: a case series

Robotic assisted (RA) retroperitoneal lymph node dissection (RPLND) has grown in popularity as it offers decreased morbidity and faster recovery compared to the open technique. Proponents of open surgery raised concerns about the oncological fidelity of the RA approach for testicular tumors where complete resection is needed. In boys > 10 years with paratesticular rhabdomyosarcoma (RMS), RPLND is indicated for staging purposes only. In this population, the RA technique should provide its benefits without concerns for oncological compromise. We present an analysis of RA-RPLND for boys with paratesticular RMS. We queried our institution's prospectively collected database of pediatric robotic cases for patients undergoing RA-RPLND post-radical orchiectomy for paratesticular mass, confirmed by pathology as RMS. Demographic, surgical, follow-up, and oncological outcomes were evaluated between 2017 and 2023. Five patients underwent RA-RPLND for paratesticular RMS. The median age was 16.1 years (15-17), with median OR time of 456 min (357-508). No conversions to open occurred. Inpatient median total opioid use was 1.8 (0.4-2.7) morphine equivalent/kg. The median lymph node yield was 27 (8-44) and post-op length of stay was 3 days (2-5). The median time to initiating adjuvant chemotherapy was 10.5 days (7-13). One patient had complications: pneumothorax attributed to central line placement and chyle leak that resolved in 1 week with dietary restriction. Our series demonstrates the feasibility, safety, and efficacy of the RA approach for RPLND in pediatric patients with paratesticular RMS. This is the most extensive case series currently in the literature and the only one exclusively done for paratesticular RMS.

Prechemotherapy Transperitoneal Robotic-Assisted Partial Nephrectomy (RAPN) for a Wilms Tumor: Surgical and Oncological Outcomes in a Four-Year-Old Patient

BACKGROUND

Wilms tumor (WT) is the most frequent renal tumor in children. The SIOP-UMBRELLA Guidelines allow for nephron-sparing surgery (NSS) in syndromic patients, as well as in cases of small (<300 mL) non-syndromic unilateral WTs, without lymph node involvement, and with a substantial expected remnant renal function, following neoadjuvant chemotherapy. We present a case of prechemotherapy transperitoneal robot-assisted partial nephrectomy (RAPN) for a unilateral, non-syndromic Wilms tumor.

METHODS

A four-year-old child presented with a solid mass measuring 3.6 cm in diameter involving the upper right renal pole, incidentally detected during an abdominal echotomography. CT scan and abdominal MRI revealed no local infiltration or lymph node involvement, suggesting that the exophytic mass could be easily resected via an NSS robotic approach. Preoperative imaging did not strongly suggest WT. A virtual 3D reconstruction of the tumor was performed.

RESULTS

After the oncologic board approval, a robot-assisted partial nephrectomy with an intraperitoneal approach was performed. Histopathological analysis confirmed the diagnosis of WT. The patient subsequently received 10 doses of vincristine as adjuvant chemotherapy. A 28-month follow-up showed no tumor recurrence.

CONCLUSIONS

Intraperitoneal RAPN may be an option for selected WT and warrants consideration as a challenging but advantageous approach.

Metanephric stromal tumor in an adult with PDGFRA mutation: a case report

BACKGROUND

Metanephric stromal tumors (MST) are rare benign renal tumors that mainly occur in infants and children. Approximately 72% of MST in children have the B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation. To date, only five cases of adult MSTs have been reported and no clear genetic alterations have been found.

CASE PRESENTATION

We report a case of MST in a 45-year-old woman who complained of left lower back pain for a week, accompanied by hypertension (150/79 mmHg). Magnetic resonance imaging (MRI) showed an abnormally enhanced nodule (1.1 cm in the middle of the left kidney), which was histopathologically consistent with an MST. The BRAF V600E mutation was not detected in tumor cells using PCR and next-generation sequencing (NGS). However, a platelet-derived growth factor receptor alpha (PDGFRA) mutation was detected in this case using NGS. The patient showed no recurrence or metastasis nine months after partial nephrectomy, and her blood pressure was consistently normal.

CONCLUSION

This is the first report of alterations in PDGFRA in MSTs. This result advances our knowledge of genetic variations in adult MSTs, which may have different gene alterations from MSTs in children.

Robotic resection of paediatric solid tumours at a single institution

BACKGROUND

To explore the clinical application of robotic-assisted surgery in paediatric solid tumours and to explore its feasibility.

METHODS

From 2015 to 2022, 53 children with solid tumours underwent robotic-assisted surgery in our centre were retrospectively analysed.

RESULTS

The mean weight of the patients was 27.7 kg, and the mean age was 6.7 years. The average tumour volume was 5.5*4.6*3.7 cm. Two procedures (3.8%) were converted. The mean total operative time was 198.5 min. The mean estimated blood loss was 27.1 ml, and no intraoperative complications occurred. Two (3.8%) patients had postoperative complications. At a median follow-up of 21.2 months, one (1.9%) patient with malignant tumours stopped treatment, and two (3.8%) patients developed tumour recurrence.

CONCLUSIONS

Robotic-assisted tumour resection is feasible in highly selected cases of young age, light weight, huge tumour or malignant tumour.

Technical advances in the surgical management of Wilms tumors in children

Surgery is one of the cornerstones of Wilms tumor treatment. In this article, we present technical advancements that are finding their way into the armamentarium of pediatric cancer surgeons. We discuss the current approaches, challenges, opportunities, and future directions of minimally invasive surgery (laparoscopic and robotics), image-guided surgery, and fluorescence-guided surgery. Furthermore, we discuss the use of intraoperative ultrasonography, as well as the use of new techniques to improve the quality of lymph node sampling.

Robot-assisted retroperitoneal lymph node dissection: a systematic review of perioperative outcomes

OBJECTIVE

To assess the safety and feasibility of robot-assisted retroperitoneal lymph node dissection (R-RPLND) and to compare the perioperative outcomes of R-RPLND with open RPLND (O-RPLND), as RPLND forms an integral part of the management of testis cancer and R-RPLND is a minimally invasive treatment option for this disease.

MATERIALS AND METHODS

The PubMed^® , Scopus^® , Cochrane Central Register of Controlled Trials, and Web of Science™ databases were searched for studies reporting perioperative outcomes of primary and post-chemotherapy R-RPLND and studies comparing R-RPLND with O-RPLND.

RESULTS

The search yielded 42 articles describing R-RPLND, including five comparative studies. The systematic review included 4222 patients (single-arm studies, n = 459; comparative studies, n = 3763). Of 459 patients in the single-arm studies, 271 underwent primary R-RPLND and 188 underwent post-chemotherapy R-RPLND. For primary R-RPLND, the operative time ranged from 175 to 540 min and the major complication rate was 4.1%. For post-chemotherapy R-RPLND, the operative time ranged from 134 to 550 min and the major complication rate was 8.5%. The conversion rate to open surgery was 2.2% in primary R-RPLND and 9.0% in post-chemotherapy R-RPLND. In comparison with O-RPLND, R-RPLND was associated with a lower transfusion rate (14.5% vs 0.9%, P < 0.001) and a lower complication rate (18.5% vs 7.8%, P = 0.002).

CONCLUSION

Robot-assisted RPLND has acceptable perioperative outcomes in both the primary and post-chemotherapy settings but a notable rate of conversion to open surgery in the post-chemotherapy setting. Compared with O-RPLND, R-RPLND is associated with a lower transfusion rate and fewer overall complications. Given the potential impact of selection bias, the optimal patient selection criteria for R-RPLND remain to be elucidated.

Utilization of robotics in pediatric surgical oncology

Despite increasing implementation of robotic surgery and minimally invasive techniques within adult surgical oncology and pediatric general surgery, the utilization of robotic-assisted resections for pediatric tumors has been met with controversy. The robotic platform affords numerous advantages over conventional surgical techniques. However, limited data and guidelines regarding patient selection, indications for the robotic approach, and long-term oncologic outcomes have delayed the widespread adoption of robotic-assisted resection of pediatric tumors. This paper reviews the benefits, limitations, and existing guidelines and data regarding the utilization of robotics in pediatric surgical oncology.

Robotic partial nephrectomy in the pediatric population: Cumulative experience at a large pediatric hospital

INTRODUCTION

Robotic partial nephrectomy is a complex minimally invasive procedure that addresses the intricate anatomy of renal masses while maximizing preservation of renal function. However, while common in adults, the evolution toward these minimally invasive procedures for children has been slow due to the anticipated technical difficulties in pediatric-sized working spaces. We present our technique and our experience with pediatric robotic partial nephrectomies that were performed with our adult urology colleagues at a large free-standing children's hospital.

METHODS

The video describes our technique for a robotic right-sided partial nephrectomy in a 14-month-old male patient. The video highlights several steps of the procedure including positioning and port placement, tumor resection, and renorrhaphy.

RESULTS

Six pediatric patients underwent robotic partial nephrectomy with our associated adult urologic surgeons from January 2019 to January 2021. The surgical pathology revealed both benign as well as malignant diagnoses.

CONCLUSION

Robotic partial nephrectomy is a feasible minimally invasive procedure in children. The collaboration with adult minimally invasive urologic surgeons with extensive adult procedural experience is recommended to avoid potential complications with this technically challenging procedure in pediatric patients. Pediatric strategies for robotic port placement are often needed to accommodate the smaller size of pediatric patients as well as tumor size.

Above and Beyond Robotic Surgery and 3D Modelling in Paediatric Cancer Surgery

Although the survival rates for children's cancers have more than doubled in the last few decades, the surgical practise has not significantly changed. Among the most recent innovations introduced in the clinic, robotic surgery and augmented reality are two of the most promising, even if they are not widespread. The increased flexibility of the motion, the magnification of the surgical field and the tremor reduction provided by robotic surgery have been beneficial to perform complex oncological procedures in children. Besides, augmented reality has been proven helpful in planning for tumour removal, facilitating early discrimination between cancer and healthy organs. Nowadays, research in the field of surgical oncology is moving fast, and new technologies and innovations wich will help to shape a new way to perform cancer surgery. Paediatric surgeons need to be ready to adopt these novel devices and intraoperative techniques to allow more radical tumour resections with fewer complications. This review aims to present the mechanism of action and indications of several novel technologies such as optical imaging surgery, high definition cameras, and intraoperative loco-regional treatments. We hope this will enhance early adoption and more research on how to employ technology for the benefit of children.

Robotic Surgery in Pediatric Oncology: Lessons Learned from the First 100 Tumors-A Nationwide Experience

BACKGROUND

While robotics has become commonplace in adult oncology, it remains rare in pediatric oncology due to the rarity of childhood cancers. We present the results of a large nationwide experience with robotic oncology, with the aim of providing practical and feasible guidelines for child selection.

METHODS

This was a prospective analysis performed over a period of 4 years. Treatment was delivered according to the Société Internationale d'Oncologie Pédiatrique/International Society of Paediatric Oncology Europe Neuroblastoma Group (SIOP/SIOPEN) protocols. Indications were approved by a certified tumor board.

RESULTS

Overall, 100 tumors were resected during 93 procedures (abdomen, 67%; thorax, 17%; pelvis, 10%; retroperitoneum, 6%) in 89 children (56 girls). The median age at surgery was 8.2 years (range 3.6-13); 19 children (21%) harbored germinal genetic alterations predisposing to cancer. No intraoperative tumor ruptures occurred. Seven conversions (8%) to an open approach were performed. Neuroblastic tumors (n = 31) comprised the main group (18 neuroblastomas, 4 ganglioneuroblastomas, 9 ganglioneuromas) and renal tumors comprised the second largest group (n = 24, including 20 Wilms' tumors). The remaining 45 tumors included neuroendocrine (n = 12), adrenal (n = 9), germ-cell (n = 7), pancreatic (n = 4), thymic (n = 4), inflammatory myofibroblastic (n = 4), and different rare tumors (n = 5). Overall, 51 tumors were malignant, 2 were borderline, and 47 were benign. The median hospital stay was 3 days (2-4), and five postoperative complications occurred within the first 30 days. During a median follow-up of 2.4 years, one child (Wilms' tumor) presented with pleural recurrence. One girl with Wilms' tumor died of central nervous system metastasis.

CONCLUSIONS

Robotic surgery for pediatric tumors is a safe option in highly selected cases. Indications should be discussed by tumor boards to avoid widespread and uncontrolled application.

Development of a Standardized Program for the Collaboration of Adult and Children's Surgeons

BACKGROUND

Children's hospitals within larger hospitals (CH/LH) have the specific clinical advantage of easily facilitated collaboration between adult and children's surgeons. These collaborations, which we have termed hybrid surgical offerings (HSOs) are often required for disease processes requiring interventions that fall outside the customary practice of children's surgeons. Formal models to describe or evaluate these practices are lacking.

METHODS

HSOs within a CH/LH were identified. Principles of systems-engineering were used to develop a standardized model (Children's Hybrid Enhanced Surgical Services [CHESS]) to describe and evaluate HSOs. Face validity was established via unstructured interviews of CH leaders and HSO surgeons. Areas for improved system-wide standardization and programmatic development were identified.

RESULTS

HSOs were identified in collaboration with adult bariatric, minimally invasive, advanced endoscopic, endocrine, thoracic, and orthopedic trauma surgical services. The CHESS framework encompassed: 1) quality improvement metrics, 2) credentialing and oversight, 3) transitions of care, 4) pediatric family-centered care, 5) maintenance of the cycle of expertise, 6) continuing medical education, 7) scholarship. While HSOs fulfilled the majority of aforementioned programmatic domains across all six HSO-providing services, areas for improvement included maintaining a cycle of expertise (33%), quality improvement metrics (50%), and pediatric family-centered care (66%).  Additional noted advantages included faster translation of adult innovation to pediatric care and facilitation of emergency interdisciplinary care.

CONCLUSION

Formal evaluation of HSOs is necessary to standardize and improve the quality of children's surgical care. Development of a structured framework such as CHESS addresses gaps in quality oversight and provides a basis for performance improvement, patient safety, and programmatic development.

Case Report: Pediatric Robotic Adrenalectomy for Virilizing Adrenal Tumor in a 4-year-old Female

Adrenocortical tumors in children are rare, with approximately 90% of children presenting with endocrine syndromes, most commonly virilization. The standard treatment remains an open resection, although there is increasing use of the minimally invasive approach. With the advent of robotic surgery, its advantages over open and conventional laparoscopy make it a viable option in select patients. Despite the adoption of robot-assisted surgery in pediatric urology, limited literature regarding robotic pediatric adrenal surgery exists, with only a few small case series. We present a female child with virilizing features due to a large functional adrenal tumor managed by robot-assisted adrenalectomy.

Robotics-Assisted Pediatric Oncology Surgery-A Preliminary Single-Center Report and a Systematic Review of Published Studies

AIM

The use of robotics-assisted surgery in oncology has been proved effective and safe in adults. Despite these results, the use of robotics has been rarely reported for pediatric oncology. Our review aims to evaluate the safety and feasibility of robotics-assisted surgery in this field, analyzing our experience and performing a systematic review of the most recent studies.

METHODS

We reviewed all patients affected by an oncological disease who underwent a robotics-assisted procedure at our institute. We performed a systematic review of the literature from 2012 to 2021 on the subjects.

FINDINGS

A total of 14 patients underwent robotics-assisted tumor resection. Eleven procedures (median age 13.2-years old) were carried out in children with adnexal lesions (seven tumor excision and four ovariectomies). Histological diagnosis was mature teratoma (six), serous papillary cystadenofibromas of the fallopian tube (two), ovarian serous cystadenoma (one), ovarian mucinous cystadenoma (one), and ovarian seromucinous cystadenoma. The median length of stay was 2 days. No recurrences or complications at a median follow-up of 2.1-years were observed. A 5-year-old girl underwent a complete posterior resection of a type 3 sacrococcygeal tumor with a robotics-assisted approach for the dissection of a possible intraabdominal residual component of the lesion. No intra- and postoperative complications were recorded. Complete excision of a recurrent differentiating neuroblastoma of the left para-renal region was performed on a 9-year-old girl. An idiopathic anaphylactic shock occurred 1 day after the procedure. At 9 months' follow-up, no local recurrences of the lesion were observed. Overall, we reported no conversion to open surgery. Lastly, a robotic excision of a growing left superior mediastinal intermixed ganglioneuroblastoma was performed on an 8-year-old girl with no postoperative complications. Follow-up was uneventful (7 months). In the literature, the rate of complications ranges from 0 to 28%, mainly related to difficult dissection and impaired anatomy. Conversion is reported in 5% of all oncological procedures, due to more invading tumors and altered anatomical features. No robotics-related complications were reported.

CONCLUSION

Robotics-assisted surgery in pediatric oncology has proven to be feasible. Nevertheless, its use should be limited to selected cases and performed by highly trained oncological surgeons. Preparation and patient positioning, alongside a correct port placement, are crucial to carrying out these procedures. Further innovations in robotics may allow a wider application of this technology in pediatric oncology.

Robotics in Pediatric Urology: Evolution and the Future

Almost 30 years have passed since the inception of minimally invasive surgery in urology and specifically in pediatric urology. Laparoscopy has now become an essential tool in the pediatric urologic armamentarium. The application of robot-assisted surgery in pediatrics has allowed for widespread utilization for common reconstructive procedures such as pyeloplasty and ureteral reimplantation. Understanding the implementation, technical considerations, and outcomes are critical for continued success and adoption. This has allowed for increased use in more complex urologic procedures such as redo pyeloplasty, dismembered ureteral reimplantation, catheterizable channel creation, and bladder augmentation.

Pediatric face transplantation: a viable option?

PURPOSE OF REVIEW

Face transplantation is no longer a young field. Reported outcomes suggest that this life-enhancing transplantation is viable and ethically justified for appropriate patients. Given that pediatric hand transplantation has been performed with promising reported outcomes, it is time to consider how to properly expand the field of face transplantation into pediatric patients.

RECENT FINDINGS

Appropriate collaboration between adult and pediatric colleagues can mitigate risks associated with expanding surgical innovation between respective patient demographics. The reported outcomes of the first pediatric hand transplant question the appropriateness of increasing immunosuppression burden to a patient on an existing regimen for prior solid organ allotransplantion. Young donor allografts prove to be more resilient, however, implying that managing rejection episodes is key to long-term viability. Expanding face transplants into a younger population must consider the social functions of the face, and may facilitate healthy personal development given the cultural value appearance has in real life and in social media.

SUMMARY

We believe that pediatric face transplantation is not just a viable option, but an ethically reasonable one as long as the field proceeds with cautious optimism.

Robotic-assisted laparoscopic management of renal tumors in children: Preliminary results

AIM

We present the preliminary results of robotic-assisted laparoscopic (RAL) total and partial nephrectomy for renal malignant tumors in children.

METHODS

This is a prospective study of patients operated with RAL between December 2016 and September 2018. Patients with Wilms tumors were treated according to the SIOP-2001 protocol. Patient and tumor characteristics, type of surgery, surgical-related morbidity, and oncologic outcomes were recorded. Results were compared with a series of patients with similar age- and tumor-related characteristics operated during the same period by an open surgical approach.

RESULTS

Ten children underwent RAL nephrectomy with a mean age of five years (3.2-14.1 years). Total nephrectomy was done in six cases for Wilms tumor and in one case for renal sarcoma; three cases were converted. Complete removal of tumor without rupture was achieved in all cases. Postoperative course was uneventful, and patients were discharged between days 2 and 7. Neither recurrence nor medium-term complications occurred. Nine patients are alive with a median follow-up of 16 months (6-27 months) and one female died from complications of central nervous system metastases one year after surgery. When compared with the open surgical approach group, median tumor volume was smaller (P = 0.005), hospital stay was shorter (P = 0.01), and operative time was similar (P = 0.20).

CONCLUSIONS

RAL total and partial nephrectomy procedure for renal tumor in children may be an option in carefully selected cases. Indication should be discussed at tumor boards and surgery performed while adhering strictly to oncological surgical rules.

Robot-Assisted Laparoscopic and Thoracoscopic Surgery: Prospective Series of 186 Pediatric Surgeries

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.
