Abstract
BACKGROUND This study reports national estimates of population characteristics and outcomes for patients with esophageal atresia with or without tracheoesophageal fistula (EA/TEF) and evaluates the relationships between hospital volume and outcomes. METHODS Patients admitted within 30 days of life who had International Classification of Diseases, 9th Edition, Clinical Modification diagnosis and procedure codes relevant to EA/TEF during 1999-2012 were identified with the Pediatric Health Information System database. Baseline demographics, comorbidities, and postoperative outcomes, including predictors of in-hospital mortality, were examined up to 2 years after EA/TEF repair. RESULTS We identified 3,479 patients with EA/TEF treated at 43 children's hospitals; 37% were premature and 83.5% had ≥1 additional congenital anomaly, with cardiac anomalies (69.6%) being the most prevalent. Within 2 years of discharge, 54.7% were readmitted, 5.2% had a repeat TEF ligation, 11.4% had a repeat operation for their esophageal reconstruction, and 11.7% underwent fundoplication. In-hospital mortality was 5.4%. Independent predictors of mortality included lower birth weight, congenital heart disease, other congenital anomalies, and preoperative mechanical ventilation. There was no relationship between hospital volume and mortality or repeat TEF ligation. CONCLUSION This study describes population characteristics and outcomes, including predictors of in-hospital mortality, in EA/TEF patients treated at children's hospitals across the United States. Across these hospitals, rates of mortality or repeat TEF ligation were not dependent on hospital volume.

Abstract
In the framework of the ITER broader approach, the International Fusion Materials Irradiation Facility (IFMIF) deuteron accelerator (2 × 125 mA at 40 MeV) is an irradiation tool dedicated to high neutron flux production for future nuclear plant material studies. During the validation phase, the Linear IFMIF Prototype Accelerator (LIPAc) machine will be tested on the Rokkasho site in Japan. This demonstrator aims to produce 125 mA/9 MeV deuteron beam. Involved in the LIPAc project for several years, specialists from CEA/Saclay designed the injector based on a SILHI type ECR source operating at 2.45 GHz and a 2 solenoid low energy beam line to produce such high intensity beam. The whole injector, equipped with its dedicated diagnostics, has been then installed and tested on the Saclay site. Before shipment from Europe to Japan, acceptance tests have been performed in November 2012 with 100 keV deuteron beam and intensity as high as 140 mA in continuous and pulsed mode. In this paper, the emittance measurements done for different duty cycles and different beam intensities will be presented as well as beam species fraction analysis. Then the reinstallation in Japan and commissioning plan on site will be reported.

Abstract
BACKGROUND "Fast-track" management (FT) challenges traditional postoperative tenets in order to minimize discomfort and optimize inpatient care. We examined the outcomes of consecutively performed laparoscopic-assisted ileocecectomy for Crohn's disease (CD), with particular focus on FT's effects in patients with underlying bowel inflammation. METHODS We retrospectively reviewed all patients undergoing isolated laparoscopic-assisted ileocecectomy for CD at our institution between 12/2000 and 12/2010, excluding patients with multiple areas of surgical CD, bladder involvement, or age >18years. RESULTS Seventy-one patients aged 8-18years underwent isolated laparoscopic-assisted ileocecectomy for CD, of which 45 met FT criteria. Individual practice patterns primarily determined which patients were FT-managed. FT management led to decreased length of stay (LOS), time to first stool, time to full diet, and intravenous narcotic use. No significant difference in complications or disease progression was observed between the two groups during 2-year follow up. CONCLUSIONS Our results suggest that FT is safe and effective in patients with CD. In a chronically ill population, counseling patients and families to expect early discharge is critical to the success of this strategy. Despite CD-related GI pathology, FT patients realized benefits in terms of LOS, time to bowel function, and narcotic use without any increase in complications.

Abstract
BACKGROUND/PURPOSE Administrative databases include large multi-institutional cohorts of patients with rare congenital anomalies that can potentially be used to characterize these diseases and study variations in practice and outcomes. The purpose of this study was to develop a methodology to accurately identify a cohort of patients with a rare disease (esophageal atresia and tracheoesophageal fistula, EA/TEF) in the Pediatric Health Information System (PHIS) database. METHODS Patients with EA/TEF treated from 2001 to 2010 were identified by chart review at two institutions and then located within the PHIS database to find ICD-9-CM coding patterns unique to EA/TEF. Subsequently, a step-wise search strategy for PHIS was developed to identify patients with EA/TEF: this included searching the ICD-9-CM diagnosis code for congenital EA/TEF; adding the ICD-9-CM code for acquired TEF; limiting age to ≤ 30 days; and adding at least one of a number of specified ICD-9-CM procedure codes. The PHIS search results were subsequently validated by chart review at each institution. RESULTS The institutional chart reviews identified 207 patients with EA/TEF. The most refined PHIS search strategy identified 221 patients. The positive predictive value of the search increased incrementally from 65% with using only the correct ICD-9 code to 96% with the full methodology. A cohort of 2977 patients with EA/TEF is identified when this search strategy is applied to the entire PHIS database. CONCLUSION Administrative databases such as PHIS can be utilized to identify cohorts of patients with rare congenital anomalies; however, cohort development requires a systematic search strategy and validation process to ensure correct identification of patients.

Abstract
BACKGROUND The purpose of this study was to report our experience with sentinel lymph node biopsy (SLNB) for pediatric soft tissue sarcomas to add to the limited literature about its feasibility, utility, and concordance with pre-operative imaging, including CT and (18)F-FDG PET (PET) scanning. METHODS Medical records of patients with a sarcoma who underwent SLNB as part of their treatment for a soft tissue sarcoma at our institution from 2000 to 2011 were identified and reviewed. RESULTS Eight patients underwent SLNB for soft tissue sarcoma during the study period. Two patients had positive SLNBs; both of these patients had rhabdomyosarcoma. Three patients with pathologically enlarged lymph nodes on CT scan underwent PET functional imaging prior to SLNB. The PET suggested the presence of nodal disease in all three patients; however, only one of these patients had a positive SLNB. CONCLUSIONS Our series confirms that SLNB is feasible in pediatric sarcoma patients. Small numbers preclude definitive conclusions regarding the utility of SLNB compared with PET, however our data suggest functional imaging alone may not be sufficient to definitively determine lymph node status in these patients. Surgical lymph node sampling may still need to be performed to accurately identify nodal status in pediatric patients with soft tissue sarcoma.

Abstract
PURPOSE OF REVIEW Outcomes for children with cancer have steadily improved and the long-term survival for most early-stage childhood malignancies is now greater than 90%. On the contrary, the prognosis for children with metastatic cancer, though significantly improved from a generation ago, is generally still very disappointing. Surgery continues to play a role in the increasingly aggressive treatment of children with metastatic disease with the ultimate goal of prolonging survival and improving quality of life. RECENT FINDINGS Most childhood tumors are relatively rare and are therefore studied using a multi-institutional cooperative group model that standardizes protocols and pools resources and data, accounting for the remarkable progress that has been made in the care of children with cancer. In some cases, this has also allowed us to recognize the utility of certain surgical therapies and the need to further study others. SUMMARY Modern surgery and critical care allow us to consider offering children with metastatic disease more aggressive surgical options in circumstances where the data suggest the potential for long-term survival. In situations where data are lacking, children might be offered a surgical option as part of an ongoing trial.

Abstract
We report on a patient with early onset pediatric bilateral pheochromocytomas caused by mosaic chromosome 11p15 paternal uniparental isodisomy (UPD). Hemihyperplasia of the arm was diagnosed in a 4-month-old female and clinical methylation testing for 11p15 in the blood was normal, with a reported detection threshold for mosaicism of 20%. She was subsequently diagnosed at 18 months with bilateral pheochromocytomas. Single-nucleotide polymorphism (SNP) array analysis of pheochromocytoma tissue demonstrated mosaic deletions of 8p12pter, 21q21.1qter, 22q11.23qter; commonly seen in pheochromocytomas. In addition, mosaic 11p15.3pter homozygosity was noted. Molecular testing for other causes of pheochromocytomas was normal, suggesting that 11p15 homozygosity was the primary event. Subsequent SNP array analysis of skin fibroblasts from the hyperplastic side demonstrated 5% mosaic paternal UPD for 11p15. We have subsequently used SNP array analysis to identify four patients with subtle hemihyperplasia with low-level mosaic UPD that was not detected by methylation analysis. Given the increased sensitivity of SNP array analysis to detect UPD along with the increased incidence of tumorigenesis in these UPD patients, we suggest that it has high utility in the clinical work-up of hemihyperplasia. The present case also suggests that 11p15 paternal UPD may be an under-detected mechanism of sporadic pheochromocytoma in the pediatric population. Furthermore, a review of the literature suggests that patients with 11p15 paternal UPD may present after 8 years of age with pheochromocytoma and raises the possibility that ultrasound screening could be considered beyond 8 years of age in this subset of hemihyperplasia and Beckwith-Wiedemann syndrome patients.

Abstract
Isolated tracheoesophageal ("H-type") fistula is a relatively uncommon congenital anomaly that can be difficult to identify and, at times, challenging to repair. We present a very unusual case of an infant with 2 distinct H-type tracheoesophageal fistulas (TEFs) identified and repaired in 1 operation. A newborn male infant presented with coughing with feeds. Contrast esophagram demonstrated an intrathoracic H-type fistula without esophageal atresia. In the operating room, rigid bronchoscopy was performed, and a second TEF was identified in the cervical region. A separate balloon catheter was placed in each fistula. The intrathoracic fistula was repaired through a thoracotomy incision, and the more proximal fistula was repaired through a cervical incision. Each repair was uncomplicated, and recovery was uneventful. Double H-type tracheoesophageal appears to be extremely rare. This case underscores the importance of searching for a second fistula by bronchoscopy before undertaking definitive repair of a TEF.

Abstract
One of the difficulties described in epidemiological studies about psychopathology in children 0-3 years of age appears during the assessment phase. In fact, the assessment of indicators of particular difficulties in children is hampered by the rapid processes of transformation of behavior that cross all areas of child development. The aim of this article was to provide an overview as complete as possible of all instruments used in the assessment phase of children 0-3 years. The literature shows a number of tools for evaluation and diagnosis of psychopathology that have been divided into four categories: mental development tests, interviews with parents, questionnaires and rating scales, evaluation of the parent-child assessment of specific diagnostic entities. The main features of each instrument are described.

Abstract
In the framework of the IFMIF-EVEDA project (International Fusion Materials Irradiation Facility-Engineering Validation and Engineering Design Activities), CEA∕IRFU is in charge of the design, construction, and characterization of the 140 mA continuous deuteron injector, including the source and the low energy beam line. The electron cyclotron resonance ion source which operates at 2.45 GHz is associated with a 4-electrode extraction system in order to minimize beam divergence at the source exit. Krypton gas injection is foreseen in the 2-solenoid low energy beam line. Such Kr injection will allow reaching a high level of space charge compensation in order to improve the beam matching at the radio frequency quadrupole (RFQ) entrance. The injector construction is now completed on the Saclay site and the first plasma and beam production has been produced in May 2011. This installation will be tested with proton and deuteron beams either in pulsed or continuous mode at Saclay before shipping to Japan. In this paper, after a brief description of the installation, the preliminary results obtained with hydrogen gas injection into the plasma chamber will be reported.

Abstract
Meckel diverticulum is the most common congenital abnormality of the gastrointestinal (GI) tract, occurring in approximately 2% of the general population. The lifetime complication rate from a Meckel diverticulum is 0.5%-2%. The most common complications include bleeding, obstruction, inflammation and perforation. However, the clinical manifestations of a Meckel diverticulum are frequently nonspecific. As a result, complications secondary to Meckel diverticulitis can mimic a variety of more common intra-abdominal processes, such as appendicitis, inflammatory bowel disease and any other cause of small bowel inflammation or obstruction. The radiologist should be aware of potential manifestations of the disease on different imaging modalities. In this pictorial essay, we illustrate several complications related to the Meckel diverticulum, in multiple modalities.

Abstract
BACKGROUND A bacterial cause is not frequently identified in children with pneumonia complicated by parapneumonic effusion (ie, complicated pneumonia). OBJECTIVES To determine the frequency of positive blood and pleural fluid cultures in children with complicated pneumonia and to determine whether broad-range 16S rRNA polymerase chain reaction (PCR) improves identification of a microbiologic cause. METHODS This prospective cohort study included children 1-18 years of age hospitalized with complicated pneumonia. RESULTS Pleural fluid drainage was performed in 64 (51.6%) of 124 children with complicated pneumonia. A microbiologic cause was identified in 11 of 64 patients (17.2%; 95% confidence interval [CI]: 8.9%-28.7%). Bacteria were isolated from pleural fluid culture in 6 of 64 patients (9.4 %; 95% CI: 3.5%-19.3%) undergoing pleural drainage; the causative bacteria were Staphylococcus aureus (n = 5) and Streptococcus pneumoniae (n = 1). Blood culture identified a bacterial cause in 3 of 44 cases (6.8%; 95% CI: 1.4%-18.7%) undergoing pleural fluid drainage; S. pneumoniae (n = 1), Haemophilus influenzae (n = 1), and S. aureus (n = 1) were isolated. Only 3 of the 19 pleural fluid samples (15.8%; 95% CI: 3.4%-39.6%) analyzed with 16S rRNA PCR were positive. S. pneumoniae was the only organism detected in all three samples; two of these three had negative pleural fluid cultures and absence of bacteria on Gram stain. S. aureus was isolated from pleural fluid culture in one patient with a negative 16S rRNA PCR test. CONCLUSIONS Causative bacteria were infrequently identified in children with complicated pneumonia. Broad-range 16S rRNA PCR only modestly improved the microbiologic yield over conventional culture methods.

Abstract
Bi-caval dual lumen venovenous extracorporeal membrane oxygenation (VV-ECMO) as a nonoperative approach to postintubation tracheal injury has not been described. We report the case of a 7-year-old boy who sustained a postintubation tracheal injury, developed acute respiratory distress syndrome from aspiration and viral pneumonitis, and was supported on bi-caval dual lumen VV-ECMO for 16 days until the trachea healed without surgical repair. Before ECMO decannulation, high-frequency percussive ventilation using a volumetric diffusive respiration ventilator was used for lung recruitment and airway clearance without disruption of the healed trachea. The use of ECMO to allow for lower mean airway pressure during initial healing and high-frequency percussive ventilation for lung recruitment and secretion clearance is a promising strategy to allow nonoperative tracheal injury repair in critically ill patients with multiple comorbidities.

Abstract
PURPOSE Roux-en-Y hepaticojejunostomy (HJ) is currently the favored reconstructive procedure after resection of choledochal cysts. Hepaticoduodenostomy (HD) has been argued to be more physiologically and technically easier but is feared to have associated complications. Here we compare outcomes of the 2 procedures. METHODS A retrospective chart review identified 59 patients who underwent choledochal cyst resection within our institution from 1999 to 2009. Demographic and outcome data were compared using t tests, Mann-Whitney U tests, and Pearson χ(2) tests. RESULTS Fifty-nine patients underwent repair of choledochal cyst. Biliary continuity was restored by HD in 39 (66%) and by HJ in 20 (34%). Open HD patients required less total operative time than HJ patients (3.9 vs 5.1 hours, P = .013), tolerated a diet faster (4.8 days compared with 6.1 days, P = .08), and had a shorter hospital stay (7.05 days for HD vs 9.05 days for HJ, P = .12). Complications were more common in HJ (HD = 7.6%, HJ = 20%, P = .21). Three patients required reoperation after HJ, but only one patient required reoperation after HD for a stricture (HD = 2.5%, HJ = 20%, P = .037). CONCLUSIONS In this series, HD required less operative time, allowed faster recovery of bowel function, and produced fewer complications requiring reoperation.

Abstract
BACKGROUND During minimally invasive operations, it is sometimes necessary to retrieve the end of a suture or a suture needle and bring it out through the abdominal wall. METHODS Using a standard needle and a length of suture, we have developed a simple device that allows the retrieval of a suture end during minimally invasive operations that require the placement of U-or stay stitches. RESULTS The author has used the device described during more than 100 laparoscopic gastrostomy placement procedures and other operations involving the placement of U- or stay stitches with excellent results and no complications. CONCLUSIONS Using a beveled hollow-bore needle and a loop of polypropylene suture, one can construct a simple device that allows the retrieval of a suture from within a body cavity during minimally invasive surgery, making the placement of U- and stay stitches easier and more precise.

Abstract
Inflammatory myofibroblastic tumors are known to sometimes regress spontaneously or in response to treatment with antiinflammatory drugs. We present the case of a 13-year-old boy with an inflammatory myofibroblastic tumor of the proximal duodenum, which regressed rapidly within days of an open surgical biopsy, resulting in perforation of the duodenum. Ketorolac was administered intravenously after the biopsy and is implicated as a potential cause of the rapid regression of the tumor. We discuss the surgical management of this patient and present a review of the literature.

Abstract
BACKGROUND Biliary dyskinesia (BD) is a consideration as a cause of chronic abdominal pain in the pediatric population. We sought to correlate the results of cholecystokinin-diisopropyl iminodiacetic acid (CCK-DISIDA) scanning, the basis for diagnosis of BD, with outcome after laparoscopic cholecystectomy. METHODS A retrospective review was performed of all patients who underwent a laparoscopic cholecystectomy from May 2000 through March 2007. The diagnosis of BD was based on CCK-DISIDA scan demonstrating a gallbladder ejection fraction (GBEF) of less than 35% and/or reproduction of pain on CCK administration or no filling of the gall bladder with a normal ultrasound examination. Hospital, General Surgery office, and Gastroenterology Office charts were reviewed for demographic and management data points. We used chi(2) and Mann-Whitney tests for statistical analysis. RESULTS For the period of review, 430 patients underwent a laparoscopic cholecystectomy including 75 patients with a preoperative diagnosis of BD. The mean age of the BD population was 14 (range, 9-19) years. Female to male ratio was 2.4:1. The mean body mass index was 24.4 kg/m(2). On average, patients had abdominal symptoms for 15.5 (range, 0.25-72) months. Each patient underwent nearly 2.5 studies (computed tomography, ultrasound, esophagogastroduodenoscopy, or upper gastrointestinal series) before diagnosis by CCK-DISIDA. The mean GBEF was 17.4%. When commented on (n = 41), pain on CCK administration was noted in 25 (61%) patients. Pathology revealed chronic cholecystitis in 44%. After laparoscopic cholecystectomy, 58 (77.33%) patients reported resolution of their abdominal pain (mean follow-up 4 months). Of the 17 patients without improvement, 7 were later diagnosed with other underlying pathology (Crohn's, hiatal hernia, cyclic vomiting). There was no difference in GBEF, age, histopathology, or sex between the two groups. There were no complications. CONCLUSION Laparoscopic cholecystectomy is a safe and effective treatment for the majority of children diagnosed with BD. Although CCK-DISIDA was used to identify biliary dysfunction, it did not correlate with outcome.

Abstract
BACKGROUND Subdiaphragmatic aortic diseases in children are rare and form a heterogeneous group. The pediatric patient presents unique challenges because of their size, concerns about proper timing and conduit for repair, and anticipating expected growth. METHODS We performed a retrospective review of operations involving the abdominal aorta and called branches in children between January 2003 and April 2007, focusing on the details of preoperative evaluation, operative technique, and outcomes. The pertinent literature is reviewed. RESULTS Twenty-two children (age, 2 days to 17 years) were included. Mean follow-up was 28 months. Aneurysms were seen in 5 children; the remainder had stenotic disease. Aneurysms were typically asymptomatic and diagnosed incidentally, whereas stenotic lesions most commonly presented with hypertension (HTN). Fourteen complex vascular repairs were performed. All of the children with aneurysms underwent prompt surgery. The children with stenoses had operations for poorly controlled HTN, claudication, and/or mesenteric ischemia. Most patients with stenotic disease were treated medically for HTN and were followed closely while awaiting optimal size and availability of autogenous conduit for reconstruction. Cryopreserved allograft was used in 3 of the aneurysm operations. Dacron grafts were used to repair 5 aortic stenotic lesions. Renal and mesenteric revascularizations were performed with saphenous vein grafts. Pediatric, general, and transplant surgeons and nephrologic and cardiologic teams were integral to evaluation and management. No major operative complications occurred. CONCLUSION Proper management of pediatric aortic vascular disease requires a multidisciplinary approach. It is best to use autologous grafts whenever possible. Children with stenotic disease should be treated medically for hypertension until they are large enough for an autologous graft reconstruction. Children with aneurysmal disease are at risk for embolism and thrombosis and therefore usually treated immediately using artificial graft material, if necessary.
