Diagnosis of Hirschsprung disease (HD) is quite entirely based on the histopathological analysis of suction rectal biopsies. This hematoxylin and eosin approach has some limitations, despite the help of acetylcholinesterase staining. The aim of this study was to assess the diagnostic value of calretinin immunochemistry as a simple and reliable method in the(More)
PURPOSE The indications for laparoscopy in pediatric urology are expanding and yet the advantages over open surgery remain unclear. We compared the results of retroperitoneal laparoscopic vs open pyeloplasty for pyeloureteral junction obstruction in children. MATERIALS AND METHODS A total of 22 children with a mean age of 88 months (range 25 to 192)(More)
BACKGROUND The authors analyzed clinical signs of vascular ring anomalies together with appropriate complementary examinations and factors predictive of outcome after surgical treatment. METHODS The authors reviewed the files of 62 patients with vascular ring abnormalities treated at Necker-Enfants Malades Hospital between January 1990 and January 2000,(More)
BACKGROUND Higher recurrence rates have been reported for thoracoscopic repair (TR) of neonatal congenital diaphragmatic hernia (CDH) compared to open repair. Our centre initiated changes in surgical management following a quality review in order to improve outcome. METHODS A retrospective review of TR patients from 2000 to 2011 at a single institution(More)
BACKGROUND The aim of the present national prospective population-based study was to assess the early morbidity of esophageal atresia (EA). METHODS All 38 multidisciplinary French centers that care for patients with EA returned a specific questionnaire about the 1-year outcome for each patient. This information was centralized, checked, and entered into a(More)
This study aimed to compare the results of thoracoscopic surgery for congenital lung diseases between infants younger than 6 months and those older than 6 months at the time of surgery in terms of operation duration, surgical complications, chest tube duration, and hospital stay. The charts of 30 thoracoscopic resections for congenital lung diseases were(More)
BACKGROUND Congenital esophageal stenosis (CES) is a rare condition frequently associated with esophageal atresia (EA).

Methods: The aim of this study was to show that even when the extended form of(More)
PURPOSE We analyzed our experience with retroperitoneal laparoscopic nephrectomy giving special attention to the learning curve, morbidity, and feasibility in a teaching institution. MATERIAL AND METHODS Between 1996 and 2004, we performed 104 laparoscopic nephrectomies in 88 children. Only four were performed via the transperitoneal approach, the others(More)
