Thoracoscopy for Pediatric Thoracic Neurogenic Tumors-A European Multi-Center Study.

Objectives: To assess the efficacy of thoracoscopy and the outcome for children with thoracic neurogenic tumors.

Methods: We performed a retrospective review of 15 European centers between 2000 and 2020 with patients who underwent thoracoscopy for a neurogenic mediastinal tumor. We assessed preoperative data, complications, and outcomes.

Necrotizing myositis case report and brief literature study.

Necrotizing myositis is an extremely rare soft tissue infection, mainly caused by Group A Streptococci. Although its presentation is nonspecific and seems harmless, it quickly leads to death in almost all cases. Therefore, diagnosis and treatment of necrotizing myositis are considered as medical emergencies.

Laparoscopic Magenstrasse and Mill Gastroplasty (M&M): Midterm Results.

Background: The Magenstrasse and Mill gastroplasty (M&M) is a gastric restrictive procedure without band or stomach resection. Short-term evaluation of the laparoscopic procedure showed low morbidity and satisfactory results on weight loss. Evidence of the validity of the technique in the longer term is scarce.

Recurrence of Solid Pseudopapillary Neoplasms of the Pancreas: Results of a Nationwide Study of Risk Factors and Treatment Modalities.

Background: Solid pseudopapillary neoplasms of the pancreas (SPPN) can relapse very late, but little is known about risk factors for recurrence and optimal treatment. We aimed to identify risk factors for recurrence and to analyze treatment modalities in all French pediatric cases of SPPN over the past 20 years.

Material And Methods: Data were collected from pediatric oncologists and surgeons, and also from adult pancreatic surgeons in order to identify late recurrences.

Concomitant nodal involvement by Langerhans cell histiocytosis and Hodgkin's lymphoma.

A 10-year-old girl with a family history of Hodgkin's lymphoma presented with a 2 month history of cervical lymphadenopathy and weight loss. Biopsy indicated concomitant nodal involvement by Langerhans cell histiocytosis and Hodgkin's lymphoma. Such an association is rare, especially so in children, but is not an isolated phenomenon, thereby prompting the question of whether Langerhans cell histiocytosis is a reactive or a neoplastic process.

Outcome of alimentary tract duplications operated on by minimally invasive surgery: a retrospective multicenter study by the GECI (Groupe d'Etude en Coeliochirurgie Infantile).

Background: Alimentary tract duplications (ATD) are a rare cause of intestinal obstruction in childhood. There are many case reports but few series about laparoscopy or thoracoscopy for ATD. The aim of our study was to report the outcome of minimally invasive surgery (MIS) for ATD.

Sternal cleft: prenatal multimodality imaging.

Sternal clefts have been reported sporadically, but there are no reports describing complete investigations of the malformation. We describe a child with isolated inferior sternal cleft diagnosed at 33 weeks of gestation and thoroughly investigated by prenatal US, MRI and CT and preoperative US. Our report highlights the importance of accurate and in-depth investigation by multimodality imaging that allows detection of accompanying serious anomalies and, hence, forms the basis for informed parental counselling and for postnatal interdisciplinary care.

Congenital absence of the left pericardium and diaphragmatic defect in sibs.

Congenital absence of the left pericardium (allowing communication between pericardial and pleural cavities) is a rare developmental defect that results from faulty partitioning of the pleuropericardic cavity during the 5th week of development. It occurs sporadically in most instances, and may be associated with other malformations of the thoracic viscera. We report here two sibs born to consanguineous parents with absent left fibrous pericardium and developmental defects of the septum transversum: left posterolateral diaphragmatic hernia in one child, left diaphragmatic eventration in the other sib.

Minimally invasive surgery for anorectal malformation in boys: a multicenter study.

Introduction: The laparoscopic pull-through for high imperforate anus in boys has recently been developed in France and Benelux. The purpose of this study was to evaluate technical difficulties and surgical complications of this approach.

Patients And Methods: This report was based on a retrospective study from January 2002 to December 2007,including 34 patients from 10 centers.

Cecostomy button for antegrade enemas: survey of 29 patients.

Objective: This study evaluated the Trap-door button use (Cook Medical, Bloomington, IL) for antegrade enemas in children.

Methods: Since 2002, patients with fecal incontinence or encopresis and constipation underwent percutaneous cecostomy under laparoscopy using a button. Technical details are described.

[Pseudopapillary tumor of the pancreas revealed by rupture of esophageal and gastric varices secondary to biliary cirrhosis due to bile duct compression].

Pseudo-papillary tumors of the pancreas are rare and usually occur in young women. We report a case with a very rare presentation (rupture of esogastric varices complicating biliary cirrhosis secondary to bile duct compression by a pancreatic tumor). After biological and radiological explorations, a duodenopancreatectomy was performed.

Application of laser capture microdissection in genetic analysis of neuroblastoma and neuroblastoma precursor cells.

Recently developed quantitative and high-throughput technologies that allow automated and rapid screening of the whole genome, transcriptome and proteome have revolutionized the field of cancer genetics. At the same time, new challenges are met, e.g.
