INTRODUCTION Thoracoscopic approach for repair of esophageal atresia (EA) and tracheo-esophageal fistula (TEF) has become a standard procedure in many pediatric surgical centers. Thoracoscopic surgery in a newborn is demanding from both the surgeon and the patient. The potential benefits for the newborn are still discussed by neonatologists, pediatric(More)
Traumatic posterior dislocation of the elbow is often associated with significant morbidity and incomplete recovery. The aim of this study was to retrospectively analyse the outcome of 33 children (median age 10.8 years). Patients underwent reduction and assessment of stability under general anaesthesia. Pure dislocations (n=10) were immobilized, whereas(More)
BACKGROUND The aim of this study is to show that five distinct types of tracheal anomalies should be differentiated with respect to therapy and prognosis. METHODS The records of 12 infants and children seen over a period of 20 years for different tracheal anomalies such as laryngotracheal stenosis (n = 3), long or short-segment stenosis of the upper (n =(More)
PURPOSE In a prospective study it was investigated whether and to what degree the morphology of the porta hepatis has a bearing on the early prognosis of children with EHBA. The results will point to consequences of surgery and to the formulation of a rational understanding of the successes and failures of HPE. METHODS The macroscopy and the microscopy of(More)
Silver-Russell syndrome (SRS) is characterized by severe intrauterine and postnatal growth failure and frequent body asymmetry. Half of the patients with SRS carry a DNA hypomethylation of the imprinting center region 1 (ICR1) of the insulin-like growth factor 2 (IGF2)/H19 locus, and the clinical phenotype is most severe in these patients. We aimed to(More)
BACKGROUND AND OBJECTIVES Intolerance of uncertainty (IU) has been linked to Generalized Anxiety Disorder (GAD), but studies experimentally manipulating uncertainty have mostly failed to find differences between GAD patients and controls, possible due to a lack of distinction between uncertainty and ambiguity. This study therefore investigated reactivity to(More)
PURPOSE Three-dimensional visualization of solid tumors is possible because of high-resolution computed tomography and magnetic resonance imaging scans. However, additional preoperative information is often desirable in complex malignancies. For the first time, the authors present a model of preoperative 3-dimensional visualization and virtual resections in(More)
BACKGROUND Volvulus without malrotation in preterm infants is a rare but potentially life-threatening event of unknown aetiology. Confusion with necrotising enterocolitis may delay surgical intervention thereby aggravating morbidity and mortality. We aimed at elucidating potential risk factors for, and characteristic clinical signs of, volvulus without(More)
BACKGROUND In patients with maljunction of pancreatic and common bile duct (CBD)-defined as a long common pancreaticobiliary channel (LCPC)-a resection of the CBD and a hepaticojejunostomy is recommended. To date, this operation is usually performed through an open approach. In this article, we report on our experience with minimally invasive surgery (MIS)(More)
Three-dimensional endorectal sonography with a specially developed system is able to produce an image of the entire pelvic floor including the sphincter muscles and the rectal wall even in small children. This special system is based on conventional endorectal ultrasound and allows recording of a controlled withdrawal of the axially rotating transducer,(More)
