RESUMO
INTRODUCTION: Total nephrectomies for the treatment of Wilms' tumor (WT) are more and more performed by laparoscopy, although indications for this approach following the UMBRELLA guidelines are currently very restrictive. The purpose of this study was to assess the compliance to the criteria of the UMBRELLA protocol for minimally invasive approach of WT. METHODS: This retrospective multicenter study included children operated on by laparoscopic total nephrectomy for suspected WT before 2020. Imaging was reviewed centrally. RESULTS: Fifty-six patients (50 WT and 6 nephrogenic rests) were operated on at a median age of 3.3 ± 2.6 years. Thirteen (23%) patients had metastasis at diagnosis. The mean operative time was 213 ± 84 min. There were eight (14.3%) conversions and five peroperative complications. A local stage III was confirmed in seven (12.5%) cases, including two for tumor rupture. Only one (1.8%) of the procedures followed the SIOP-UMBRELLA indications for laparoscopy. The criterion "ring of normal parenchyma" was met only once. Conservative surgery seemed possible in ten (17.9%) cases. The extension of the tumor beyond the ipsilateral edge of the vertebra after chemotherapy and a volume over 200 mL were associated with an increased risk of conversion (p = 0.0004 and p = 0.001 respectively). After a mean follow-up of 5.2 ± 4.0 years, although there was no local recurrence, one death occurred due to metastatic progression at 15 months postoperatively. CONCLUSIONS: The laparoscopic approach of WT beyond the UMBRELLA recommendations was feasible with low risk of local recurrence. Its indications may be updated and validated.
RESUMO
INTRODUCTION: Cataract surgery is the most common surgical procedure performed in France. While the incidence of intraoperative complications affecting visual prognosis is extremely low, given the large number of patients operated on, the absolute number of patients affected by complications is quite high. Complication rates are significantly higher when ophthalmology residents (ORs) perform the surgery. Although lack of experience remains the main risk factor, sleep deprivation may adversely affect ORs' successful surgery rate. The value of the EyeSi® surgical simulator in initial training has been demonstrated to increase cataract surgery safety through the transfer of surgical skills from the simulator to the operating room. However, there is no consensus regarding how much training is needed before the first-time ORs are allowed to operate. There is also no scientific evidence that sleep deprivation is associated with a decrease in surgical performance. Establishing a validated protocol for cataract surgery training using the EyeSi surgical simulator (referred to further as the EyeSi) and identifying risk factors for intraoperative complications related to sleep deprivation will improve cataract surgery safety and lead to the reorganization of our healthcare systems. METHODS AND PLANNED OUTCOMES: This multi-centre educational cohort study will include two distinct axes which will both aim to reduce the risks of cataract surgery. Enrollment will include 16 first-year ORs for Axis 1 and 25 experienced residents for Axis 2, all from the University Hospitals of Nantes, Tours, Angers and Rennes. Axis 1 will focus on investigating the learning curve of first-year ORs using the EyeSi, following the training program recommended by the "College des Ophtalmologistes Universitaires de France" in order to set up a future "licence to operate." Axis 2 will evaluate the impact of sleep deprivation on the surgical performance of experienced ORs using the EyeSi. TRIAL REGISTRATION: ClinicalTrial.gov identifier: NCT05722080.
RESUMO
BACKGROUND DATA: EA is the most frequent congenital esophageal malformation. Long gap EA remains a therapeutic challenge for pediatric surgeons. A case case-control prospective study from a multi-institutional national French data base was performed to assess the outcome, at age of 1 and 6 years, of long gap esophageal atresia (EA) compared with non-long gap EA/tracheo-esophageal fistula (TEF). The secondary aim was to assess whether initial treatment (delayed primary anastomosis of native esophagus vs. esophageal replacement) influenced mortality and morbidity at ages 1 and 6 years. METHODS: A multicentric population-based prospective study was performed and included all patients who underwent EA surgery in France from January 1, 2008 to December 31, 2010. A comparative study was performed with non-long gap EA/TEF patients. Morbidity at birth, 1 year, and 6 years was assessed. RESULTS: Thirty-one patients with long gap EA were compared with 62 non-long gap EA/TEF patients. At age 1 year, the long gap EA group had longer parenteral nutrition support and longer hospital stay and were significantly more likely to have complications both early post-operatively and before age 1 year compared with the non-long gap EA/TEF group. At 6 years, digestive complications were more frequent in long gap compared to non-long gap EA/TEF patients. Tracheomalacia was the only respiratory complication that differed between the groups. Spine deformation was less frequent in the long gap group. There were no differences between conservative and replacement groups at ages 1 and 6 years except feeding difficulties that were more common in the native esophagus group. CONCLUSIONS: Long gap strongly influenced digestive morbidity at age 6 years.

Objective: Despite recent progress in caring for patients born with esophageal atresia (EA), undernutrition and stunting remain common. Our study objective was to assess nutritional status in the first year after birth with EA and to identify factors associated with growth failure. Study design: We conducted a population-based study of all infants born in France with EA between 2010 and 2016. Through the national EA register, we collected prenatal to 1 year follow-up data. We used body mass index and length-for-age ratio Z scores to define patients who were undernourished and stunted, respectively. Factors with P < 0.20 in univariate analyses were retained in a logistic regression model. Results: Among 1,154 patients born with EA, body mass index and length-for-age ratio Z scores at 1 year were available for about 61%. Among these, 15.2% were undernourished and 19% were stunted at the age of 1 year. There was no significant catch-up between ages 6 months and 1 year. Patients born preterm (41%), small for gestational age (17%), or with associated abnormalities (55%) were at higher risk of undernutrition and stunting at age 1 year (P < 0.05). Neither EA type nor surgical treatment was associated with growth failure. Conclusion: Undernutrition and stunting are common during the first year after birth in patients born with EA. These outcomes are significantly influenced by early factors, regardless of EA type or surgical management. Identifying high-risk patient groups with EA (i.e., those born preterm, small for gestational age, and/or with associated abnormalities) may guide early nutritional support strategies.
RESUMO
OBJECTIVES: The present study aimed to assess long-term functional outcomes of children with anorectal malformations (ARMs) across a network of expert centers in France. METHODS: Retrospective cross-sectional study of patients ages 6-30âyears that had been surgically treated for ARM. Patient and ARM characteristics (eg, level, surgical approach) and functional outcomes were assessed in the different age groups. RESULTS: Among 367 patients, there were 155 females (42.2%) and 212 males (57.8%), 188 (51.2%) cases with, and 179 (48.8%) higher forms without, perineal fistula. Univariate and multivariate statistical analyses with logistic regression showed correlation between the level of the rectal blind pouch and voluntary bowel movements (odds ratio [OR]â=â1.84 [1.31-2.57], Pâ<â0.001), or soiling (ORâ=â1.72 [1.31-2.25], Pâ<â0.001), which was also associated with the inability to discriminate between stool and gas (ORâ=â2.45 [1.28-4.67], Pâ=â0.007) and the presence of constipation (ORâ=â2.97 [1.74-5.08], Pâ<â0.001). Risk factors for constipation were sacral abnormalities [ORâ=â2.26 [1.23-4.25], Pâ=â0.01) and surgical procedures without an abdominal approach (ORâ=â2.98 [1.29-6.87], Pâ=â0.01). Only the holding of voluntary bowel movements and soiling rates improved with age. CONCLUSION: This cross-sectional study confirms a strong association between anatomical status and functional outcomes in patients surgically treated for ARM. It specifically highlights the need for long-term follow-up of all patients to help them with supportive care.

Background: This study aimed to create a consensus statement on the indications, applications, and limitations of robotics in pediatric urology. Methods: After a panel and interactive discussion focused on pediatric robotics, a televoting with 10 questions was administered to 100 pediatric surgeons/urologists attending the joint meeting of the French Group of Pediatric Laparoscopy (GECI)/Italian Society of Videosurgery in Infancy (SIVI) in 2021. The results of televoting were analyzed electronically using Mentometer software. Results: Ninety-four percent of participants stated that the cutoff weight for robotics should be >10-15 kg. A minimum of 20-30 procedures should be performed to become confident in robotics (74%). Pediatric urology is the main field of application (73%) and pyeloplasty is the best indication for robotics (63%). Technical problems may happen intraoperatively in 1/10-15 cases (64%). The mean duration of robotic procedures ranges from 150 to 200 minutes (72%). The main drawbacks of robotics are high costs and limited development of miniaturized instruments (74%). Ninety-five percent believed that the costs of robotics may significantly drop with the availability of more robotic brands. The main advantages of robotics over laparoscopy include improved dexterity, easier suturing, and better ergonomics (100%), whereas the main disadvantage of sharing the robot with other specialties is the wearing out of instruments (100%). Conclusions: This is the first consensus statement, endorsed by the GECI and SIVI societies, on the use of robotics in pediatric urology. The need to introduce more robotic brands on the market to lower the costs and to develop miniaturized instruments to be adopted in infants less than 10 kg emerged. Pediatric urology is the main field of application of pediatric robotics, and robotic pyeloplasty is the most common procedure performed. Proctorship is needed for the first 20-30 procedures and technical problems may occur intraoperatively in 1/10-15 cases. The main advantages of robotics over laparoscopy are improved dexterity, easier suturing, and better surgeon ergonomics.

INTRODUCTION: Gastro-esophageal reflux disease (GERD) is the most frequent long-term morbidity of congenital diaphragmatic hernia (CDH) survivors. Performing a preventive fundoplication during CDH repair remains controversial. This study aimed to: (1) Analyze the variability in practices regarding preventive fundoplication; (2) Identify predictive factors for fundoplication. (3) Evaluate the impact of preventive fundoplication on gastro-intestinal outcomes in children with a CDH patch repair; METHODS: This prospective multi-institutional cohort study (French CDH Registry) included CDH neonates born in France between January 1st, 2010-December 31st, 2018. Patch CDH was defined as need for synthetic patch or muscle flap repair. Main outcome measures included need for curative fundoplication, tube feed supplementation, failure to thrive, and oral aversion. RESULTS: Of 762 CDH neonates included, 81 underwent fundoplication (10.6%), either preventive or curative. Median follow-up was 3.0 years (IQR: 1.0-5.0). (1) Preventive fundoplication is considered in only 31% of centers. The rates of both curative fundoplication (9% vs 3%, p = 0.01) and overall fundoplication (20% vs 3%, p < 0.0001) are higher in centers that perform preventive fundoplication compared to those that do not. (2) Predictive factors for preventive fundoplication were: prenatal diagnosis (p = 0.006), intra-thoracic liver (p = 0.005), fetal tracheal occlusion (p = 0.002), CDH-grade C-D (p < 0.0001), patch repair (p < 0.0001). After CDH repair, 8% (n = 51) required curative fundoplication (median age: 101 days), for which a patch repair was the only independent predictive factors identified upon multivariate analysis. (3) In neonates with patch CDH, preventive fundoplication did not decrease the need for curative fundoplication (15% vs 11%, p = 0.53), and was associated with higher rates of failure to thrive (discharge: 81% vs 51%, p = 0.03; 6-months: 81% vs 45%, p = 0.008), tube feeds (6-months: 50% vs 21%, p = 0.02; 2-years: 65% vs 26%, p = 0.004), and oral aversion (6-months: 67% vs 37%, p = 0.02; 1-year: 71% vs 40%, p = 0.03). CONCLUSIONS: Children undergoing a CDH patch repair are at high risk of requiring a curative fundoplication. However, preventive fundoplication during a patch repair does not decrease the need for curative fundoplication and is associated with worse gastro-intestinal outcomes in children. LEVEL OF EVIDENCE: II - Prospective Study.

INTRODUCTION: There have been numerous reports of robotic pediatric surgery in the literature, particularly regarding urological procedures for school-aged children. Thoracic procedures appear to be less common, despite the fact that encouraging results were reported more than 10 years. Our aim was to report a national experience of esophageal robotic-assisted thoracoscopic surgery (ERATS) and to discuss the most appropriate indications. MATERIALS AND METHODS: A retrospective multicenter study was conducted to compile the ERATS performed at five French surgical centers that have been involved in spearheading robotic pediatric surgery over the past 15 years. The data were supplemented by a review of the literature. RESULTS: Over the study period, 68 cases of robotic thoracic surgery were performed at the five pediatric centers in question. ERATS was performed for 18 patients (mean age 7.1 years [ ± 5.6]) in four of the centers. These comprised seven esophageal duplications, four esophageal atresias, five Heller's myotomies, and two cases of esophagoplasty. A conversion was needed for two neonates (11%) due to exposure difficulties. Four other procedures for patients who weighed less than 15 kg were successfully completed without causing postoperative complications. In the past 12 years, 22 other cases of ERATS were published worldwide. The indications were the same, except for esophagoplasty, which was not found. CONCLUSION: Aside from accessibility issues with the robotic platform, the main limitation is still very much that the low body weight of children results in incompatibility between the size of the trocars and the size of the intercostal space. ERATS is clearly a feasible procedure with technical advantages for most pediatric cases with body weights more than 15 kg. A transdiaphragmatic abdominal approach should be considered for lower esophagus surgery.

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.

BACKGROUND AND OBJECTIVES: Respiratory diseases are common in children with esophageal atresia (EA), leading to increased morbidity and mortality in the first year. The primary study objective was to identify the factors associated with readmissions for respiratory causes in the first year in EA children. METHODS: A population-based study. We included all children born between 2008 and 2016 with available data and analyzed factors at birth and 1 year follow-up. Factors with a P value <.10 in univariate analyses were retained in logistic regression models. RESULTS: Among 1460 patients born with EA, 97 (7%) were deceased before the age of 1 year, and follow-up data were available for 1287 patients, who constituted our study population. EAs were Ladd classification type III or IV in 89%, preterm birth was observed in 38%, and associated malformations were observed in 52%. Collectively, 61% were readmitted after initial discharge in the first year, 31% for a respiratory cause. Among these, respiratory infections occurred in 64%, and 35% received a respiratory treatment. In logistic regression models, factors associated with readmission for a respiratory cause were recurrence of tracheoesophageal fistula, aortopexy, antireflux surgery, and tube feeding; factors associated with respiratory treatment were male sex and laryngeal cleft. CONCLUSIONS: Respiratory morbidity in the first year after EA repair is frequent, accounting for >50% of readmissions. Identifying high risk groups of EA patients (ie, those with chronic aspiration, anomalies of the respiratory tract, and need for tube feeding) may guide follow-up strategies.

ABSTRACT: Intractable ascites is a rare condition in children mainly caused by cirrhosis or lymphatic disorders. Internal drainage may be considered as rescue therapy. In our department, 4 patients ages from 2âmonths to 15âyears old underwent a peritoneovenous shunt (PVS) placement between 2010 and 2020. The surgically inserted device was a pumping device that enabled to drain ascites from the peritoneum into the venous system via the internal jugular vein (Denver shunt, BD Company, NJ). Immediate efficient drainage was achieved in all cases and lasted up to 9âyears. Two major complications occurred: a postoperative fat embolism requiring urgent temporary ligation of the shunt and endocarditis shortly after inguinal hernia repair performed 16âmonths after placement of the shunt. Implementation of a PVS may be a useful procedure in patients with refractory ascites. Chylous ascites should be drained and washed totally before activating the device to avoid fat embolism. Antibiotic prophylaxis is required when abdominal surgery is planned while the device is in place.

OBJECTIVE: To identify the risk factors for early mortality and morbidity in a population with distal esophageal atresia (EA)-tracheoesophageal fistula. STUDY DESIGN: Cohort study from a national register. Main outcomes and measures included early mortality, hospital length of stay (LoS), need for nutritional support at 1 year of age as a proxy measure of morbidity, and complications during the first year of life. RESULTS: In total, 1008 patients with a lower esophageal fistula were included from January 1, 2008, to December 31, 2014. The survival rate at 3 months was 94.9%. The cumulative hospital LoS was 31.0 (17.0-64.0) days. Multivariate analysis showed that intrahospital mortality at 3 months was associated with low birth weight (OR 0.52, 95% CI [0.38-0.72], P < .001), associated cardiac abnormalities (OR 6.09 [1.96-18.89], P = .002), and prenatal diagnosis (OR 2.96 [1.08-8.08], P = .034). LoS was associated with low birth weight (-0.225 ± 0.035, P < .001), associated malformations (0.082 ± 0.118, P < .001), surgical difficulties (0.270 ± 0.107, P < .001), and complications (0.535 ± 0.099, P < .001) during the first year of life. Predictive factors for dependency on nutrition support at 1 year of age were complications before 1 year (OR 3.28 [1.23-8.76], P < .02) and initial hospital LoS (OR 1.96 [1.15-3.33], P < .01). CONCLUSIONS: EA has a low rate of early mortality, but morbidity is high during the first year of life. Identifying factors associated with morbidity may help to improve neonatal care of this population.

Introduction: The widespread use of robotic surgery has provided surgeons a high-quality and alternative method to perform pyeloplasty. Indeed, robot-assisted technology has made it a lot easier to obtain the advanced technical skills required to perform this procedure. The learning curve (LC) reflects the increase in learning as a function of experience. Robot-assisted laparoscopic pyeloplasty (RALP) represents a well-standardized and reproducible procedure with an LC that allows reliable results to readily be obtained. The aim of our study was to compare the RALP LC of senior versus junior surgeons. Materials and Methods: We reviewed all of the RALP procedures performed at three pediatric surgery centers between November 2007 and November 2018. Three senior surgeons and 4 junior surgeons performed the robotic procedures. Neither the senior nor the junior surgeons had previous experience with robotic surgery; they had experience with conventional laparoscopic procedures but not with laparoscopic pyeloplasty. The primary metric that we selected to evaluate competence acquisition was a composite outcome defined by a combination of operative time (OT), complications, and surgical success. The complications were rated according to the Clavien-Dindo classification expressed by a complication factor; surgical success was expressed as a success factor, and we used a cumulative sum (CUSUM) analysis to determine the LC. The CUSUM method, through its multioutcome approach, is a very effective way to evaluate LCs. Results: Between November 2007 and November 2018, 3 senior surgeons and 4 junior surgeons performed 88 RALP procedures. The included patients had a median age of 6.1 years (range 7 months-16 years). The median duration of follow-up was 6.4 years (range 14 months-12 years). The median OT was 198.86 minutes (range 106-335 minutes). By CUSUM analysis of the composite outcome, we found that despite the junior surgeons having performed fewer procedures than the senior surgeons, their LCs exhibited an earlier inflection point (Fig. 1) followed by a constant rate of improvement in proficiency, thus indicating a more rapid learning process. The median composite scores for the senior surgeons and the junior surgeons were 299 (range 210-370) and 193 (range 131-255), respectively, after seven procedures. Conclusion: Assuming proper exposure to robotics and an adequate case volume, we demonstrated that junior surgeons can readily achieve comparable levels of expertise compared with senior practitioners in the field of pediatric RALP. It can be assumed that the LC in robotic pyeloplasty is not only directly influenced by the individual surgical experience but also by the experience of the surgical team.

In Hirschsprung's disease (HSCR), postoperative course remains unpredictable. Our aim was to define predictive factors of the main postoperative complications: obstructive symptoms (OS) and Hirschsprung-associated enterocolitis (HAEC). In this prospective multicentre cohort study, samples of resected bowel were collected at time of surgery in 18 neonates with short-segment HSCR in tertiary care hospitals. OS and HAEC were noted during postoperative follow-up. We assessed the enteric nervous system and the intestinal epithelial barrier (IEB) in ganglionic segments by combining immunohistochemical, proteomic and transcriptomic approaches, with functional ex vivo analysis of motility and para/transcellular permeability. Ten HSCR patients presented postoperative complications (median follow-up 23.5 months): 6 OS, 4 HAEC (2 with OS), 2 diarrhoea (without OS/HAEC). Immunohistochemical analysis showed a significant 41% and 60% decrease in median number of nNOS-IR myenteric neurons per ganglion in HSCR with OS as compared to HSCR with HAEC/diarrhoea (without OS) and HSCR without complications (p = 0.0095; p = 0.002, respectively). Paracellular and transcellular permeability was significantly increased in HSCR with HAEC as compared to HSCR with OS/diarrhoea without HAEC (p = 0.016; p = 0.009) and HSCR without complications (p = 0.029; p = 0.017). This pilot study supports the hypothesis that modulating neuronal phenotype and enhancing IEB permeability may treat or prevent postoperative complications in HSCR.

INTRODUCTION: Laparoscopic surgery (LS) may lead to musculoskeletal disorders (MSDs) and an increase in physical and mental workloads to the surgeon. Robot-assisted surgery (RAS) should improve the ergonomy of the surgeon. This study assesses the experience influence in surgical ergonomics between LS and RAS. METHODS: LS and RAS lasting more than 60 min of effective operative time were compared. During the surgical procedure, the physical discomfort was evaluated using the Borg scale. At the end, the mental workload was evaluated using the NASA-TLX index. After global analysis, the experienced and young surgeons were assessed. RESULTS: 88 RAS and 82 LS were evaluated. During LS, the physical discomfort was significantly higher in all segments, and the pain increased significantly during the procedure in all segments compared to that evaluated in the RAS (p < 0.05). Forearms and the back were the most painful. The young surgeons did not display any improvement in the physical ergonomics of the RAS compared to the LS. Concerning the mental ergonomics, the overall workload and performance were significantly greater during the LS compared to the RAS (p < 0.05). For the young surgeons, the overall workload, the effort, the mental and the physical demands were greater during LS (p < 0.05). For the experienced surgeons, the physical demand was lower during the RAS compared to the LS (p < 0.05). However, the experienced surgeons expressed a feeling of greater performance after the LS (p < 0.01). RAS significantly reduces the onset of MSDs compared to LS, especially for the experienced surgeons. CONCLUSION: RAS significantly reduces the onset of MSDs compared to LS, especially for the experienced surgeons.

OBJECTIVE: To identify predictors of and factors associated with the performance of antireflux surgery during the first year of life in children born with esophageal atresia. STUDY DESIGN: All patients were included in a French registry for esophageal atresia. All 38 multidisciplinary French centers completed questionnaires about perinatal characteristics and one-year outcome for children born with esophageal atresia. RESULTS: Of 835 infants with esophageal atresia born in France from 2010 to 2014, 682 patients, excluding those with long-gap esophageal atresia, were included. Three patients had type I, 669 had type III, and 10 had type IV esophageal atresia. Fifty-three children (7.8%) received fundoplication during the first year of life. The median age at the time of the end-to-end esophageal anastomosis was 1.1 day (range 0-15). Multivariate analysis identified three perioperative factors that predicted the need for early antireflux surgery: anastomotic tension (P = .004), associated malformations (P = .019), and low birth weight (P = .018). Six other factors, measured during the first year of life, were associated with the need for antireflux surgery: gastroesophageal reflux (P < .001), anastomotic stricture (P < .001), gastrostomy (P < .001), acute life-threatening event (P = .002), respiratory complications (P = .045), and poor nutritional status (P < .001). CONCLUSIONS: Gastroesophageal reflux disease, low birth weight, poor nutrition, and surgical anastomosis difficulties predicted the performance of antireflux surgery in the first year of life in infants with esophageal atresia.

INTRODUCTION: Laparoscopic fundoplicature for gastroesophageal reflux disease has become the gold standard because of the improvement of postoperative rehabilitation compared with the open procedure. The robot-assisted surgery has brought new advantages for the patient and the surgeon compared with laparoscopy. We studied this new approach and the learning curve. MATERIALS AND METHODS: Sixty robot-assisted fundoplicatures were performed in two university pediatric surgery centers. Data of the patients were recorded, including peroperative data (operation length and complications), postoperative recoveries, and clinical evolution. The learning curve was evaluated retrospectively and each variable was compared along this learning curve. RESULTS: We observed a flattening of the learning curve after the 20th case for one surgeon. The mean operative time decreased significantly to 80 ± 10 minutes after 20 cases. There were no conversions to an open procedure. A revision surgery was indicated for 4.7% of the patients by a surgical robot-assisted laparoscopic approach. CONCLUSION: The robotic system appears to add many advantages for surgical ergonomic procedures. There is a potential benefit in operating time with a short technical apprenticeship period. The setting up system is easy with a short docking time.

OBJECTIVES: The main objective of this study is to report our experience in a university hospital in the surgical management of thyroid disease in pediatric patients. We also aim to analyze the results and evaluate the efficacy of fine-needle aspiration biopsy (FNAB) and frozen section analysis. METHODS: A retrospective review of thyroid surgeries from January 1997 to December 2017 was conducted. Patients aged under 18 who underwent total or partial thyroidectomy were included. The indication of the surgery, the investigation results, the surgical technique used and the final diagnosis were reviewed and analyzed. RESULTS: A total of 75 patients were included. 80% (n = 60) were females and 20% (n = 15) were males. The average age was 13.3 years ± 3.76 and age range was 3-18 years. The indication for thyroidectomy was thyroid nodule in 80% (n = 60), Grave's disease in 13.3% (n = 10), multiple endocrine neoplasm type II (MEN II) in 6.7% (n. 5). FNAB was done in 42.7% (n = 32/75) with sensitivity and specificity of 62.50% and 94.4%, respectively, the positive predictive value was 83.3% and the negative predictive value was 85%. Frozen section, which is a quick intraoperative micro and/or macroscopic examination, was done in 66.7% (n = 50/75). It was malignant in 12% (n = 6/50) and was benign in 88% (n = 44/50). Among benign results, nine (n = 9/44) patients had malignant disease in final pathological diagnosis. Its sensitivity and specificity were 40% and 100%, respectively, the positive predictive value and the negative predictive value were 100% and 79.6%, respectively. Total thyroidectomy was done in 54.7% (n = 41/75) and partial thyroidectomy was done in 45.3% (n = 34/75). Of the 75 patients, 29.3% (n = 22) had thyroid carcinoma on final pathological analysis. CONCLUSION: Thyroid diseases that require surgical intervention are rare in pediatric populations. However, when surgery is indicated, there is higher risk of malignancy compared to adults. Our study showed that FNAB has a lower specificity and sensitivity compared to adults, and that surgical decision should be made considering all investigations. We also showed that frozen section is considered primarily for papillary thyroid carcinoma but is not reliable for follicular carcinoma or Bethesda IV. Finally, thyroid surgery in children and adolescents must be part of global multidisciplinary management.

Aim of the Study: We described the initial experience of four referral centers in the treatment of primary obstructive megaureter (POM) in children, by high-pressure balloon dilatation (HPBD) of the ureterovesical junction with double JJ stenting. We managed a retrospective multicenter study to assess its effectiveness in long-term. Methods: We reviewed the medical records of all children who underwent HPBD for POM that require surgical treatment from May 2012 to December 2017 in four different institutions. The primary outcome measured was ureterohydronephrosis (UHN) and its degree of improvement after the procedure. Secondary outcomes were postoperative complications and resolution of preoperative symptomatology. Main Results: Forty-two ureters underwent HPBD for POM in 33 children, with a median age of 14.7 months - (range: 3 months -15 years). Ureterohydronephrosis improves in 86% of ureters after one endoscopic treatment. Three cases required a second HPBD. Four patients required surgical treatment for worsening of UHN after endoscopic treatment. The post-operative complication rate was 50% (21 ureters). In 13 cases (61%), they were related to double J stent. The median follow-up was 24 months (2 months -5 years) and all patients were symptom-free. Conclusion: We reported the first multicenter study and the largest series of children treated with HPBD, with an overall success rate of 92%. Endoscopic treatment can be a definitive treatment of POM since it avoided reimplantation in 90% of cases. Complications are mainly due to double J stent.
