Abstract
<b> Introduction:</b> Laparoscopic adrenalectomy is more widely recognized as a valuable treatment method for benign and malignant tumours. </br></br> <b>Aim:</b> This study reviews over 20-year experience with laparoscopic adrenalectomy in children in Central-West Poland. </br></br> <b>Materials and methods:</b> During the last 21 years, 5041 laparoscopic procedures were performed, among them 39 adrenalectomies in children aged from 2 days to 17 years. The following data were analysed: patient's age at diagnosis and surgery, lesion volume in CT/MRI examination, duration of surgery, the incidence of complication after surgery, and length of hospitalization. </br></br> <b>Results:</b> The volume of adrenal lesion visualized by CT or MRI before surgery varied from 0.5 cm3 up to 490 cm3, with a median of 14 cm3. As many as 80% of adrenalectomies allowed radical removal of the lesion and 92% of those procedures were performed without any complications. From all data analysed, only age, both at diagnosis and at surgery, was significantly lower in patients with a malignant lesion. </br></br> <b>Conclusions:</b> Laparoscopic adrenalectomy is a valuable method to use in paediatric patients for both benign and malignant adrenal lesions. However, in patients with malignant adrenal lesions it may be expected that the procedure will be more difficult due to the lower age and larger lesion size.

Abstract
Pediatric adrenal tumors are uncommon entities that are frequently occult and identified incidentally or by recognizing symptoms related to hormone overproduction. They often have a genetic underpinning, arise from the medulla or cortex, can be malignant or benign, and require precise diagnostic algorithms. However, pseudotumors must also be a diagnostic consideration. Therapeutic interventions and plans are tumor dependent, but surgery is a cornerstone of treatment. Ongoing surveillance after treatment, regardless of malignant determination, is of utmost importance as well.

Abstract
OBJECTIVE To estimate the results of minimally invasive adrenalectomy in children and compare our data with worldwide results. MATERIAL AND METHODS There were 65 patients aged from 3 months to 17 years with different organic diseases of adrenal glands. Children have undergone surgery for the period since 2003 to 2018. RESULTS Incidentalomas accounted 33.8% of all resected tumors. Bilateral lesion was diagnosed in 12% of patients. The largest neoplasm (12 cm) was diagnosed in a 9-year-old child. Intraoperative bleeding occurred in 2 patients. Endoscopic surgery did not require conversion in any case. CONCLUSION We accumulated unique experience of laparoscopic resection of benign lesions of adrenal glands. Our results are satisfactory and comparable with data of other national and foreign colleagues. Only close collaboration of pediatric surgeons and endocrinologists could lead to successful and safe treatment of these patients. Patients with suspected malignancies should receive treatment at special hospitals with oncological service.

Posterior retroperitoneoscopic adrenalectomy for pediatric adrenal tumors. J Pediatr Surg 2019; 54:2348-2352.

Abstract
BACKGROUND/AIMS Posterior retroperitoneoscoic adrenalectomy has been reported as an option for adrenal tumor resection but is not commonly performed in children owing to the extreme semikneeling position advocated to flatten the lumbar lordosis in order to achieve adequate retroperitoneal space. As children have smaller lordosis angles, flattening of the lordosis and creation of optimal retroperitoneal space may be achieved with less hip flexion. We used pediatric lumbar lordosis measurements to develop a modified prone jackknife position and report our experiences with this setup for posterior retroperitoneoscopic adrenalectomy for adrenal tumors. METHODS Lordosis angles were measured on sagittal computed tomography (CT) and magnetic resonance imaging (MRI) studies of patients with adrenal tumors and compared to normal references. The data were used to develop our modified prone jackknife position. Selected patients with adrenal tumors underwent posterior retroperitoneoscopic adrenalectomy in this position. Patient demographics, diagnoses, operative times, complications, postop analgesia requirements, and length of hospitalization were analyzed. RESULTS CT and MRI studies were analyzed for 20 patients with adrenal tumors diagnosed in our institution from 2012 to 2017; median lordosis angle was 27.84° (range: 15.50°-36.48°) - less than reference lordosis angles of respective age groups, and flexion angles of common operating tables. Five patients underwent retroperitoneoscopic adrenalectomy between June 2016 and June 2018. Histological diagnoses were neuroblastoma, adrenal hyperplasia, pheochromocytoma, and adrenal angiomatoid fibrous histiocytoma. Median age was 4 years [range: 1-11]. Median operating time was 137 min [range 111-181 min]. No conversions to open surgery were required. One patient had intraoperative bleeding from the adrenal vein. Only 1 patient required postoperative opioids for analgesia. Median length of hospitalization after surgery was 2 days (range: 2-3 days). CONCLUSIONS Pediatric patients can achieve flattening of lumbar lordosis with less extreme positioning. Posterior retroperitoneoscopic adrenalectomy in a modified prone jackknife position is a feasible operation for pediatric patients with small adrenal masses. TYPE OF STUDY Clinical research paper. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Laparoscopic adrenalectomy (LA) is the gold standard and is widely performed in adults, but its use in children is relatively new. We aim to present our experience in twenty-five children with diverse adrenal pathologies and to discuss an extensive review of pediatric LA in English literature. METHODS Medical records of children with adrenal tumors admitted to a tertiary center and treated with LA were reviewed. Characteristics and outcome of patients were compared with results of a systematic Pubmed/Medline literature review. RESULTS Transperitoneal LAs were performed for 12 malignant and 14 benign adrenal masses (size range: 2-8cm) in 25 children (median age:63months). Fourteen lesions were on the right side, and there was one bilateral case. There were no conversion and no complication within 36months of follow-up. A literature review revealed 437 pediatric LAs with left side predomination (51.4%). The indication was a malignant lesion in 60.2% of the cases (sizes range: 1-10cm). The transperitoneal route was preferred in 94.2% of the procedures. Conversion and complication rates were 7.5% and 3.1%, respectively. CONCLUSION LA should be preferred in selected children with adrenal pathologies. The transperitoneal route seems to be the standard approach for pediatric surgeons. Preoperative planning and surgical expertise are the keys to success. TYPE OF THE STUDY Case series with systematic literature review. LEVEL OF EVIDENCE IV.

Abstract
Pheochromocytoma (PCC) and paraganglioma (PGL) are rare chromaffin cell tumors which secrete catecholamines and form part of the family of neuroendocrine tumors. Although a rare cause of secondary hypertension in pediatrics, the presentation of hypertension in these patients is characteristic, and treatment is definitive. The gold standard for diagnosis is via measurement of plasma free metanephrines, with imaging studies performed for localization, identification of metastatic lesions and for surgical resection. Preoperative therapy with alpha-blocking agents, beta blockers, and potentially tyrosine hydroxylase inhibitors aid in a safe pre-, intra- and postoperative course. PCC and PGL are inherited in as much as 80% of pediatric cases, and all patients with mutations should be followed closely given the risk of recurrence and malignancy. While the presentation of chromaffin cell tumors has been well described with multiple endocrine neoplasia, NF1, and Von Hippel-Lindau syndromes, the identification of new gene mutations leading to chromaffin cell tumors at a young age is changing the landscape of how clinicians approach such cases. The paraganglioma-pheochromocytoma syndromes (SDHx) comprise familial gene mutations, of which the SDHB gene mutation carries a high rate of malignancy. Since the inheritance rate of such tumors is higher than previously described, genetic screening is recommended in all patients, and lifelong follow-up for recurrent tumors is a must. A multidisciplinary team approach allows for optimal health-care delivery in such children. This review serves to provide an overview of pediatric PCC and PGL, including updates on the preferred methods of imaging, guidelines on gene testing as well as management of hypertension in such patients.

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
The emergence of minimally invasive surgery about 20 years ago revolutionized pediatric urology. Advances in pediatric devices allowed the widespread use of minimally invasive techniques in almost the entire range of pediatric urology. In this context, laparoscopy and later retroperitoneoscopy were developed and applied in a wide spectrum of urological diseases. Both approaches have since presented benefits and disadvantages that have been documented in various series. However, few comparative studies have been conducted. The aim of this review is to compare the two approaches and establish which is preferable in each field of pediatric urology.

Abstract
Purpose: The use of a minimally invasive approach for adrenalectomy is poorly defined in pediatric patients, although laparoscopic adrenalectomy is considered a standard procedure in adults. The aim of our study was to describe the safety and feasibility of minimally invasive adrenalectomy in children on the basis of surgical skills and results. Materials and Methods: This was a retrospective study of 4 pediatric laparoscopic adrenalectomies performed at our center between 2009 and 2012. All patients underwent transperitoneal lateral laparoscopic adrenalectomies (2 right and 2 left adrenalectomies). Results: Four laparoscopic adrenalectomies were performed. Indications for surgery were neuroblastoma in 2 patients, secernent adrenocortical tumor in 1 patient, and adrenocortical nodular hyperplasia in 1 patient. Patients had a mean age of 87 months (range, 17–156 months) at diagnosis, and the average lesion size was 3.23 cm (range, 0.7–6.4 cm). All laparoscopic adrenalectomies were successful, no conversions to open surgery were required, and no postoperative complications or deaths occurred. The average operating time was 105 minutes (range, 80–130 minutes), blood loss during surgery was minimal, and the mean postoperative hospital stay was 3.75 days (range, 3–5 days). None of the patients showed signs of recurring disease at 15-month follow-up. Conclusions: Laparoscopic adrenalectomy is a safe, feasible, and reproducible technique offering numerous advantages, including shortening of operating times and postoperative hospital stays, as well as reduction of blood loss and complications. It also provides good visibility and easy access to other organs.

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
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
We report symptomatic cycling Cushing disease in a 11-year-old boy that was managed with simultaneous bilateral laparoscopic adrenalectomy. Positioning and the surgical technique have been fully described. Excellent results were achieved. Recent application of laparoscopic adrenalectomy for various adrenal pathology is highly effective and offers better results than open surgery. Post-operative recovery after laparoscopic technique is significantly shorter than the open technique.

Abstract
OBJECTIVES Right Laparoscopic adrenalectomy (LA) is technically more challenging than left LA, because of the anatomical position of the right adrenal gland and vein. We modified the technique for right LA to optimize the procedure, and compared the operative outcome with standard technique. PATIENTS AND METHODS The operative outcome of 13 cases of right adrenal mass treated with modified LA were compared retrospectively with 29 cases of standard right LA. For modified right LA, we used a 4-port transperitoneal laparoscopic approach that omitted the subxiphoid trocar (classically used for liver retraction), and instead, an assistant applied continuous, dynamic upward liver retraction in a plane perpendicular to the inferior vena cava (IVC). RESULTS Modified Right LA was done in 13 patients (3 men, 23.1%), without difficulty and with excellent direct exposure of the upper and medial aspect of the adrenal gland and adrenal vein. Mean operative time was significantly shorter compared with standard technique (122.3 ± 20.1 vs. 165 ± 33.6 min; P < 0.0001) There were no bleeding complication and open conversion in modified technique which was promising compared with 2 bleeding complications in our experience with 29 cases of right LA using standard technique. CONCLUSION Modified right LA with a 4-port approach and dynamic upward liver retraction in a plane perpendicular to IVC resulted in direct exposure of the upper and medial aspect of the adrenal gland and adrenal vein. This approach can be effective in challenging cases when the infrahepatic fossa is poorly exposed.

Abstract
PURPOSE Reporting on the laparoscopic technique for adrenal disease in children and adolescents has been limited. We review here our experience with laparoscopic adrenal surgery in children. PATIENTS AND METHODS 19 laparoscopic unilateral adrenalectomies were performed in 10 girls and 7 boys (mean age 3.9 years) during 1998-2011. The clinical diagnosis before surgery was virilizing tumor (n = 8), pheochromocytoma (n = 3), nonfunctioning solid adrenal tumor (n = 3), mixed adrenocortical tumor (n = 2), cystic adrenal mass (n = 1). Unilateral adrenal lesions were 20-65 mm at the longest axis on computerized tomography (12 right side, 7 left side). RESULTS The final clinicopathological diagnosis was cortical adenoma (n = 9), pheochromocytoma (n = 3, bilateral in two), neuroblastoma (n = 1), ganglioneuroblastoma (n = 1), ganglioneuroma (n = 1), adrenocortical carcinoma (n = 1), benign adrenal tissue (n = 1). Average operative time was 138.5 min (range 95-270). Blood transfusion was required in one case (5%). No conversion to open surgery was required and no deaths or postoperative complications occurred. Average hospital stay was 3.5 days (range 2-15). Average postoperative follow-up was 81 months (range 2-144). Two contralateral metachronic pheochromocytomas associated with von Hippel-Lindau syndrome occurred, treated with partial laparoscopic adrenalectomy (one without postoperative need of cortisone replacement therapy). CONCLUSIONS Laparoscopic adrenalectomy is a feasible procedure that produces good results. It can be used safely to treat suspected benign and malignant adrenal masses in children with minimal morbidity and short hospital stay.

Abstract
PURPOSE Minimally invasive adrenalectomy (MIA) is the criterion standard for removal of small adrenal tumors in adults. The purpose of this review was to determine the place of MIA in children. METHODS The authors conducted a systematic review of the pediatric and adult literature about MIA, focusing on the technique and indications. RESULTS Minimally invasive adrenalectomy appears superior to open adrenalectomy for small tumors. The potential advantages of MIA are appealing for postoperative pain, risk of intestinal obstruction, and quality of scars. The most common approach is the transperitoneal lateral laparoscopy, which allows for a large working space. For small tumors or for bilateral adrenalectomy, the prone retroperitoneoscopy is a promising new technique. In children, the learning curve is an issue because the indications are rare. The most common indication is neuroblastoma without image-defined surgical risk factors. The incidence of local recurrence is low, but the follow-up is short in most cases. CONCLUSIONS Minimally invasive adrenalectomy is promising for removal of small adrenal tumors. Long-term follow-up is required to evaluate the efficacy of MIA in neuroblastomas. Benign diseases are excellent candidates for this minimally invasive technique.

Abstract
PURPOSE: Although commonly performed in adults, laparoscopic adrenalectomy in children is performed only in centres with advanced laparoscopic expertise. MATERIALS AND METHODS: This is a retrospective analysis of laparoscopic adrenalectomies performed at a single centre between January 2003 and May 2010. After preoperative evaluation with biochemical assays and radiologic imaging, surgery was performed by using the lateral transabdominal approach in all patients. RESULTS: Ten laparoscopic adrenalectomies (including three bilateral) were performed in seven children, with a mean age of 9.6 years. The tumours ranged from 2 – 7 cms in size. The operative durations were 75 – 130 minutes (unilateral) and 250 – 270 minutes (bilateral). Operative blood loss was minimal. There were no open conversions, but terminal hand assistance was required in one large right pheochromocytoma. The postoperative hospital stay ranged from 3 – 10 days. The final pathological diagnoses included pheochromocytoma, hyperplasia and neuroblastoma. Follow-up at 24 – 87 months was uneventful. CONCLUSION: With adequate experience in laparoscopy, it is possible to perform adrenalectomy in selected children.

Abstract
INTRODUCTION Laparoscopic adrenalectomy is well established as the standard technique for all indications of adrenalectomy except adrenal carcinoma; however, some also consider large adrenal masses a relative contraindication. We present a video of a laparoscopic excision of a large ganglioneuroma and right adrenalectomy in a 12-year-old female. METHODS Our patient was noted to have a right suprarenal mass on a computed tomography scan following complaints of back and abdominal pain. Upon surgical consultation, she underwent a magnetic resonance imaging, which showed a 7.9 x 4.4 x 5.6 cm heterogeneously enhancing suprarenal lesion that was either arising from or compressing the right adrenal gland. The patient's preoperative work-up included normal urinary metanephrines, alpha-fetoprotein, and beta-HCG. After discussion with the patient and family, the decision was made to proceed with laparoscopic excision of the mass. RESULTS The patient underwent successful laparoscopic excision of the suprarenal mass and right adrenalectomy and was discharged from the hospital on postoperative day 2. During the procedure, retraction was achieved by using a combination of 5-mm grasping instruments, Endokittner dissectors (Ethicon Endosurgery Cincinnati, OH), and a suction irrigator to provide traction and counter traction. A flexible 5-mm liver retractor (Mediflex; Velmed, Inc., Wexford, PA) was placed directly through the abdominal wall without a trocar in order to elevate the liver from the area of the right adrenal and retroperitoneum. This enabled us to "rotate" the lesion out from behind the vena cava and from along the vertebral bodies. The pathology revealed an 8.5 x 7.0 x 3.0 cm ganglioneuroma, with primarily neural and Schwann cell-type tissue with interspersed large, prominent ganglion cells, and a normal adrenal gland. CONCLUSIONS As demonstrated by our video, large adrenal masses in the pediatric population can be successfully excised laparoscopically with appropriate surgeon comfort and experience.

Abstract
Laparoscopic adrenalectomy and adrenal biopsy are technically feasible in children. There are no absolute contraindications to the laparoscopic approach, but for neuroblastomas and other adrenal neoplasms, care must be taken to maintain the principles of cancer surgery. As opposed to adults, there are fewer benign indications for adrenalectomy, but in selected cases, laparoscopic resection of the adrenal is feasible. Both laparoscopic and retroperitoneoscopic approaches are recommended, with the choice being dictated by the experience of the surgeon. Recommendations throughout this guideline are based on class 3 evidence, with a single article demonstrating class 2 evidence, based on a retrospective comparison.

Abstract
Pheochromocytomas are rare neuroendocrine tumors that secrete catecholamines and usually arise from the adrenal medulla. Catecholamine-producing tumors that arise from extra-adrenal chromaffin tissue are referred to as paragangliomas, or extra-adrenal pheochromocytomas. Contrary to the traditional "Rule of Tens," as many as 25% of pheochromocytomas occur in hereditary tumor syndromes, such as multiple endocrine neoplasia-2, von Hippel-Lindau disease, neurofibromatosis-1, or hereditary or familial paraganglioma syndrome. Surgical resection remains the only curative therapy for pheochromocytomas, and advances in minimally invasive techniques have shown laparoscopic adrenalectomy to be safe and effective. Paragangliomas are extremely rare tumors, especially in children, and the role of laparoscopy in their treatment is evolving. This case report and the accompanying video demonstrate that the laparoscopic approach to retroperitoneal paraganglioma resection provides excellent exposure of the tumor and surrounding structures. Given proper patient preparation and perioperative monitoring, laparoscopic exploration and resection of paragangliomas can be safely and successfully accomplished in children. In addition, genetic analysis should be considered for all patients presenting with these tumors.

Abstract
PURPOSE The experience with minimally invasive surgery (MIS) in the treatment of neuroblastoma (NB) is anecdotal. The purpose of this study was to evaluate a retrospective cohort of NB patients who underwent MIS resection of their primary tumors. METHODS A retrospective study of NB patients who underwent MIS resection of their primary tumors over a 3-year period was undertaken. Study outcomes included complications, completeness of resection, and event-free and overall short-term survival. RESULTS Of a total of 21 children who underwent surgical resection for NB during the period of study, 8 (38%) underwent selected MIS resection. Six of the eight (75%) tumors were adrenal in origin and the remainder were located in the posterior mediastinum. Distribution by International Neuroblastoma Staging System (INSS) stage was: stage 1 (3), stage 2 (2), and stage 4 (3). One stage 4 tumor was N-myc amplified. All stage 4 patients experienced a >50% tumor volume cytoreduction in response to preoperative chemotherapy. All MIS resections were performed without need for blood transfusion, or conversion to open procedure, and there were no perioperative complications. All eight patients were alive and disease-free at a median 18-month follow-up. CONCLUSIONS With appropriate preoperative case selection based on anatomic features, MIS tumor resection in patients with NB can be performed safely and effectively.

Abstract
BACKGROUND Since indications for laparoscopic adrenalectomy have progressively expanded to pediatric surgery, preliminary reports have studied the laparoscopic approach for abdominal neuroblastoma (NB). We aimed to report on the indications and the results of laparoscopic resection in a large series of abdominal NBs. METHODS A retrospective multicenter study included 45 children with abdominal NBs (28 localized, 11 stage 4, 6 stage 4s) and laparoscopic resection of their abdominal primary tumor. Primary site of the tumor was the adrenal gland in 41 cases and retroperitoneal space in 4. The median age at surgery was 12 months (1-122); median tumor size was 37 mm (12-70). Resection was performed through transperitoneal laparoscopy (n = 38) or retroperitoneoscopy (n = 7). RESULTS Complete macroscopic resection was achieved in 43 of 45 children (96%). The median duration of pneumoperitoneum was 70 min (30-160), and the length of hospital stay was 3 days (2-9). Four procedures (9%) were converted to open surgery, and tumor rupture occurred in three cases. Of the 28 children with localized disease, there was a 96% overall survival (OS) rate after a median follow-up of 28 months (4-94). There was one local relapse in this subgroup, with subsequent complete remission. For the entire 45-children cohort, four children died and three presented a recurrence resulting in OS, disease-free survival, and event-free survival rates of 84% +/- 8.1, 84% +/- 8.2, and 77% +/- 9.1 respectively. CONCLUSION Laparoscopic resection of abdominal primary allows effective local control of the disease in a wide range of clinical situations of neuroblastoma, with an acceptable morbidity.

Abstract
Adrenal tumors in children may be benign or malignant. In addition, both benign and malignant tumors may be hormonally active, leading to hypertension, metabolic crises, and endocrinopathies. These tumors may be found incidentally or secondary to signs and symptoms of the aforementioned disorders. Both a metabolic and a radiographic work-up are required before treatment of an adrenal tumor. The primary therapy for most adrenal lesions is surgical, though some are treated medically or require chemotherapy before excision. Laparoscopy has become the surgical approach of choice in both adult and pediatric patients with localized disease. Open surgical approaches remain necessary in patients with extensive locally invasive or metastatic disease.

Abstract
The spectrum of laparoscopic surgery in children has developed dramatically; what was initially used as a diagnostic method to identify an impalpable testis is now commonly used for complex reconstructive procedures such as pyeloplasty. Laparoscopic orchidopexy and nephrectomy are well established and are used at many centres. Laparoscopic partial nephrectomy, adrenalectomy and dismembered pyeloplasty series have reported shorter hospital stays and operative times that are comparable with that of open techniques, and/or decreasing with experience. The initial experiences with laparoscopic ureteric re-implantation and laparoscopically assisted bladder reconstructive surgery are reported, with encouraging results for feasibility, hospital stay, and cosmetic outcome.

Abstract
OBJECTIVE To review our initial experience with the retroperitoneoscopic approach, which is rapidly becoming the procedure of choice for paediatric adrenalectomy. Swift access to the vascular pedicle makes this approach ideal for adrenal surgery where haemodynamic instability is a common feature. METHOD Patients were placed in a fully prone position and the locations of the 12th rib, iliac crest and paravertebral muscles were marked. A 10-mm incision was made lateral to the para-vertebral muscle, halfway between the iliac crest and costal margin. A retroperitoneal working space was created around the kidney using a homemade balloon. A 10-mm Hasson port was then inserted. A 5-mm working port was placed lateral to the tip of the 12th rib and, if necessary, a second was inserted medial to the camera port. Dissection was performed with diathermy and/or Harmonic Scalpeltrade mark and the adrenal vessels were divided between clips. The specimen was retrieved in an endopouch through the 10-mm port. RESULTS Over 16 months, six adrenalectomies were performed in five patients (three boys and two girls); two right, two left and one bilateral. Median age at surgery was 8 years. Presentation was with hypertension (n=2), Cushing's syndrome (n=2) and abdominal pain (n=1). Median operative time was 154 min. A single-instrument port adrenalectomy was performed in three patients. Histopathological diagnosis included adrenal cyst (n=1), cystic phaeochromocytoma (n=1), adrenal cortical tumour (n=2) and central Cushing's disease (n=1). All were completely resected. All patients remain symptom free with a median follow up of 17 months. CONCLUSION These cases represent our initial institutional experience with retroperitoneoscopic adrenalectomy. The senior reporting surgeons have already surmounted the general learning curve for laparoscopy, and this experience has proved vital to expand our repertoire with encouraging early results. This is our technique of choice as it provides a superior view of the adrenal gland and vessels, with good intraoperative haemodynamic stability.

Abstract
This article is a comprehensive review of the current indications and recent literature pertaining to laparoscopic techniques in pediatric urology. Basic concepts such as instrumentation, anesthetic considerations, and complications are reviewed. Specific techniques and indications are also explored. As the field of pediatric urology continues to expand, it still lags behind adult urology. With improvements in technology, however, and with new surgeons entering the field with a basic laparoscopic background, pediatric urologic laparoscopy continues to progress. Currently, procedures such as laparoscopic exploration for undescended testicles and laparoscopic nephrectomy are accepted as the 'gold standard', and are performed at most institutions. Other procedures, such as laparoscopic pyeloplasty and laparoscopic reconstructive surgery, have only recently been introduced and are primarily available at centers with surgeons experienced in laparoscopy. It is our hope that minimally invasive surgical approaches to urologic conditions will become available to all children and become commonplace at most institutions.

Abstract
BACKGROUND This study focuses on the clinical presentation, surgical technique, and results of bilateral laparoscopic adrenalectomy in three girls aged 6, 13, and 14. MATERIALS AND METHODS This retrospective study included two girls with bilateral tumors (pheochromocytomas in one case, recurrent leiomyosarcomas in the other case) and a girl with micronodular hyperplasia associated with Cushing's syndrome. RESULTS Six transperitoneal laparoscopic adrenalectomies were performed with no conversions. The average operative time was 137 minutes (range 125-148); the mean estimated blood loss was 75 mL; the mean size of the adrenal lesions was 8 cm (range, 0.5-9); and the mean length of hospital stay was 3 days (range, 2-4). Resolution of clinical and biochemical parameters of adrenal hyperfunction was accomplished in the patients with adrenocortical hyperplasia and pheochromocytoma. No tumor recurrence has been so far found in the case of the leiomyosarcomas. CONCLUSION Bilateral laparoscopic adrenalectomy can be performed safely and effectively with a shorter hospital stay, minimal blood loss, and excellent functional outcome in the pediatric population.

Abstract
Adrenal tumors, apart from neuroblastoma, are relatively rare in infancy and childhood. Most adrenal lesions are benign, and both benign and malignant tumors may be hormonally active thus, making accurate preoperative diagnosis difficult. The two main malignant tumors are adrenocortical carcinoma and pheochromocytoma. In both tumors, it may be difficult to determine benign from malignant and the biologic behavior and degree of invasion may portend a more malignant course. Surgical excision is the primary therapy for both tumors, including excision of metastatic and recurrent tumor. An open procedure should be considered for invasive adrenocortical carcinoma and in pheochromocytomas in which preoperative imaging demonstrates metastatic nodal disease. A laparoscopic approach is preferred for lesions in which preoperative imaging demonstrates a localized lesion. Chemotherapy, although without proven efficacy, is utilized in some children with metastatic or unresectable disease.

Abstract
Survival rates for children with kidney tumors approach 90% for even the most advanced stages of disease, but the surgical management of large lesions remains challenging. With the development of additional chemotherapeutic regimens and the use of radiation therapy, survival rates have improved dramatically. The National Wilms' Tumor Study has conducted four long-term studies addressing how adjunctive therapy may be tailored optimally to maximize survival and minimize the exposure to chemotherapy and radiation therapy.

Abstract
PURPOSE The aim of this study was to review the authors' experience with laparoscopic adrenalectomy in the pediatric age group. METHODS This is a retrospective analysis of laparoscopic adrenalectomies performed in children at King Faisal Specialist Hospital & Research Centre, between June 1997 and March 2003. Ten children had laparoscopic adrenalectomies during this period. They were between 3 weeks to 12 years of age and there was an equal number of boys and girls. Case selection was based mainly on the size of the lesion and its localized nature as seen on the imaging studies. The transperitoneal approach was used in all cases. RESULTS Eleven laparoscopic adrenalectomies were performed in 10 children (1 was bilateral adrenalectomy). Presenting features were virilization (n = 3), Cushing's syndrome (n = 1), antenatally detected adrenal cyst (n = 1), hypertension (n = 1), hepatomegaly (n = 1), loin pain with hematuria (n = 1) and an incidental adrenal mass (n = 1). One was a child with stage IV adrenal neuroblastoma postchemotherapy for resection of the residual tumor. On imaging studies, the tumors were between 2.8 and 7 cm in their largest dimension. Operating time ranged from 118 to 180 minutes in the unilateral resections, whereas the bilateral laparoscopic adrenalectomy required 330 minutes. Two had to be converted to open procedures. Postoperative hospital stay was between 2 and 15 days. Pathologic diagnoses were as follows: adrenal cortical adenoma (n = 3), adrenal medullary hyperplasia (n = 2), adrenal cortical carcinoma (n = 1), ganglioneuroma (n = 1), and neuroblastoma (n = 3). There were no complications. Follow-up ranged from 3 months to 6 years. The only mortality in our study group was in the child with stage IV neuroblastoma who died of disseminated disease 9 months later. In the rest, there has been no local recurrence or metastases, and the biochemical and hormonal parameters have remained normal in the functional tumors. CONCLUSIONS We believe that in a select group of pediatric adrenal lesions, laparoscopic adrenalectomy is a safe and effective procedure with the potential benefits of minimally invasive procedures.

Abstract
Laparoscopic adrenalectomy has become the procedure of choice for the surgical management of most adrenal tumors, including functional and non-functional lesions. The role of laparoscopic adrenalectomy in the management of malignant adrenal tumors is controversial and most adrenocortical cancers are generally treated by open adrenalectomy. Laparoscopic adrenalectomy can be performed by both the anterior or lateral trans-abdominal approach and by the lateral or posterior retro-peritoneal approach, with each method being suitable for specific indications. Although there are no randomized trials comparing laparoscopic with open adrenalectomy, the laparoscopic approach is associated with shorter hospital stay, reduced pain and improved cosmesis. This review discusses the indications and contraindications, technique and outcomes for laparoscopic adrenalectomy.

Abstract
PURPOSE OF REVIEW Laparoscopic procedures in paediatric urology are gaining popularity, with an increasing number of centres performing advanced surgery. Indications have expanded from diagnostic to ablative surgery and more recently to reconstructive procedures. The current status of the indications and results of different laparoscopic procedures dealing with paediatric urology are reviewed. RECENT FINDINGS Laparoscopic orchiopexy for intra-abdominal testis gives better results than classic open surgery procedures. Palomo modified varicocelectomy with lymphatic preservation is the optimal surgical procedure to treat varicocele in adolescents. The retroperitoneal approach to renal surgery is gaining popularity. Total and partial nephrectomies are feasible in comparable operative times with open surgery and shortened hospital stays. Dismembered pyeloplasty remains a challenging procedure limited to few centres, with excellent midterm results. Laparoscopic adrenal surgery has been extended to neuroblastoma in selected cases. Laparoscopic transvesical ureteric re-implant is now feasible, and opens a new era in bladder surgery. Finally, results of the initial experience with robot-assisted pyeloplasty are now available in children, and showed similar results with regard to the postoperative course, but shorter operative times with experience. SUMMARY The value of laparoscopic orchiopexy for intra-abdominal testis and ablative surgery such as total and partial nephrectomy and adrenalectomy has been confirmed. Robot-assisted laparoscopic surgery will probably popularize challenging procedures such as pyeloplasty and ureterovesical re-implant, which are still limited to a few centres. Despite an increase in the number of publications dealing with the results of laparoscopic procedures, efforts are still needed to validate the benefits of such procedures over open surgery.

Abstract
Recent improvements in laparoscopic equipment, technique, and skills have contributed to advancement of the laparoscopic approach to even relatively rare pediatric surgical diseases. Two invasive operations that now may be approached laparoscopically are adrenalectomy and esophagomyotomy. Both techniques, initially described in the early 1990s, are particularly well suited for the laparoscopic approach and have become accepted as the preferred technique among general surgeons. Despite infrequent indications for either of these operations in children, pediatric surgeons experienced in minimally invasive techniques may apply the laparoscopic approach in a safe and effective manner. Furthermore, regarding achalasia in the pediatric population specifically, the offering of a less-invasive surgical approach may contribute toward more primary definitive surgical management being offered initially rather than after prolonged supportive medical care. The goal of this article is to familiarize the reader with the current laparoscopic approach to benign pediatric adrenal conditions and esophageal motility disorders in children.
