International survey on the management of esophageal atresia

INTRODUCTION Because many aspects of the management of esophageal atresia (EA) are still controversial, we evaluated the practice patterns of this condition across Europe. METHODS A survey was completed by 178 delegates (from 45 [27 European] countries; 88% senior respondents) at the EUPSA-BAPS 2012. RESULTS Approximately 66% of respondents work in centers where more than five EA repairs are performed per year. Preoperatively, 81% of respondents request an echocardiogram, and only 43% of respondents routinely perform preoperative bronchoscopy. Approximately 94% of respondents prefer an open approach, which is extrapleural in 71% of respondents. There were no differences in use of thoracoscopy between Europeans (10%) and non-Europeans (11%, p = nonsignificant). Approximately 60% of respondents measure the gap intraoperatively. A transanastomotic tube (90%) and chest drain (69%) are left in situ. Elective paralysis is adopted by 56% of respondents mainly for anastomosis tension (65%). About 72% of respondents routinely request a contrast study on postoperative day 7 (2-14). Approximately 54% of respondents use parenteral nutrition, 40% of respondents start transanastomotic feeds on postoperative day 1, and 89% of respondents start oral feeds after postoperative day 5. Pure EA: 46% of respondents work in centers that repair two or more than two pure EA a year. About 60% of respondents opt for delayed primary anastomosis at 3 months (1-12 months) with gastrostomy formation without esophagostomy. Anastomosis is achieved with open approach by 85% of respondents. About 47% of respondents attempt elongation of esophageal ends via Foker technique (43%) or with serial dilations with bougies (41%). Approximately 67% of respondents always attempt an anastomosis. Gastric interposition is the commonest esophageal substitution. CONCLUSION Many aspects of EA management are lacking consensus. Minimally invasive repair is still sporadic. We recommend establishment of an EA registry.

Fractures of the talus--differences between children and adolescents.

BACKGROUND Fractures of the talus represent serious injuries of the foot skeleton. The most significant complications include osteonecrosis and posttraumatic malalignment with subsequent arthritis. The aim of our study was to compare treatment and outcome of fractures of the talus between children and adolescents. METHODS From 1990 to 2005, 24 patients (18 male, 6 female) presented with 25 fractures of the talus. The medical records were reviewed retrospectively. Follow-up was performed by radiographical grading, and the functional outcome was measured using the Foot-Function-Index. RESULTS Nine patients were 12 years of age or younger, and 15 patients presenting 16 talar fractures were older than 12 years. Although most fractures of the talus in children younger than 12 years were classified as Marti-Weber type I and II fractures, more than two thirds of the fractures in patients older than 12 years were Marti-Weber type III and IV fractures. Two thirds of the patients younger than 12 years were treated nonoperatively, whereas nonoperative treatment was possible in only three talar fractures in adolescents. No necrosis at follow-up (mean period, 3.2 years; range, 7 months to 8.4 years after end of treatment) was detected in children (<12a), whereas five patients older than 12 years developed persisting necrosis. CONCLUSION Even though there is no apparent difference in the cause of the trauma leading to fractures of the talus, adolescents present with more severe fractures of the talus compared with children younger than 12 years. In addition, we did not observe persistent osteonecrosis in patients younger than 12 years old, and the outcome is favorable in most cases irrespective of the mode of treatment.

Evaluation of fractures in children and adolescents in a Level I Trauma Center in Austria.

BACKGROUND Injury represents a major concern for children and adolescents worldwide. It is estimated that 10% to 25% of all pediatric injuries will result in fractures. This study aimed to analyze the epidemiology, gender distribution, age, and circumstances of fractures in childhood in a Level I Trauma Center in Austria. METHODS Children managed with fractures between December 2004 and October 2006 were prospectively evaluated. Patients were divided into four age groups: infants (<1 year), preschool children (1-6 years), school-aged children (6-14 years), and adolescents (>14 years). RESULTS The study included 3,339 patients younger than 19 years, who presented with 3,421 fractures. There was a male predominance (61.3%, n = 2,096). Girls (38.7%, n = 1,325) had a lower mean age at presentation of 8.2 years (boys, 9.8 years). An increase in the incidences of fractures was observed until a peak of 11 years in girls and 12 years in boys. A majority of fractures occurred in sports facilities (34.7%), followed by those at home (17.6%) and outdoors (16.7%). The most frequent mechanisms were falls on level surface (41.9%), falls from a height <3 m (23.2%), and involuntary contact with persons or objects (18.2%). The most common fractures were those of the distal radius (15.3%), followed by those of the finger (14%) and distal forearm fractures (8%). CONCLUSION As the Department of Pediatric Surgery in Graz serves as the referral center at least for nearly all major pediatric fractures in the Austrian state of Styria, mechanisms and patterns of major fractures in this study can serve as the basis for state-wide pediatric injury prevention efforts. These prevention strategies should not aim to reduce the level of exposure but should increase the risk awareness and encourage children and their parents to use necessary precautions.

Galeazzi Lesions in Children and Adolescents: Treatment and Outcome

A Galeazzi fracture is defined as a fracture of the radius associated with dislocation of the distal radioulnar joint. Treatment in children and adolescents is usually possible with closed reduction and casting. The objective of this retrospectively designed study was to describe all Galeazzi lesions treated at our department during a 3-year period. One hundred ninety-eight patients with displaced fractures of the radius alone or both bones of the forearm were reviewed. In 26 (13%) cases, a Galeazzi lesion was found and these patients formed the study group. Outcome was assessed using the Gartland-Werley score. Eight of 26 (31%) fractures were recognized initially and classified as a Galeazzi lesion. Casting after fracture reduction was possible in 22 patients. Thirteen patients were treated with immobilization in a below-elbow cast and nine with an above-elbow cast. Four patients were treated operatively. The results were excellent in 23 cases and good in three cases. In cases of distal forearm fractures, a possible Galeazzi lesion should be considered. However, proper reduction of the radius with concomitant reduction of the distal radioulnar joint and cast immobilization provides good to excellent outcome even if the Galeazzi lesion is primarily not recognized.Level of Evidence: Level IV, therapeutic study.

Intramedullary nailing for the treatment of dislocated pediatric radial neck fractures.

INTRODUCTION Pediatric radial neck fractures represent 5-10% of all elbow fractures. Open reduction allows anatomic fracture fixation but compromises the vulnerable blood supply of the radial head. Intramedullary nailing combines the advantages of closed reduction and stable internal fracture fixation. MATERIAL AND METHODS During a 6-year-period the medical records of all children sustaining a radial neck fracture treated operatively at our institution were analyzed retrospectively. RESULTS Forty-two patients with dislocated fractures of the radial neck were treated with intramedullary nailing. The average age of the patients was 8 years. Thirty-eight patients (90%) could be treated with closed fracture reduction and retrograde nailing. Open fracture reduction was required in 4 (10%) patients, and in 2 patients necrosis of the radial head occurred. Loss of reduction was seen in 7 (17%) patients. Excellent results were found in 38 patients, good results in 2 patients, and poor results in another 2. CONCLUSION The retrograde nailing technique for the treatment of dislocated fractures of the radial neck in pediatric patients is a simple, short and safe procedure.

Pediatric Ovarian Tumors - Dilemmas in Diagnosis and Management

BACKGROUND Ovarian tumors are rare in the pediatric age group and thus diagnostic and treatment strategies are heterogeneous. This study aims to evaluate ovarian tumors with a focus on age at presentation, imaging characteristics, diagnostic strategy, tumor presentation and management. METHODS Data was collected retrospectively from patients admitted between 1991 and 2008 for the evaluation and therapy of ovarian tumors. RESULTS Twenty-five patients were identified with neoplastic ovarian lesions (mean age 10.7 years). Sixteen patients (64%) underwent surgery for benign and 9 (36%) for malignant tumors. Benign tumors (n=16) had a mean diameter of 10.7 cm and mean age at presentation was 9.6 years compared to a diameter of 18.6 cm and 12.3 years in the malignant group (n=9). Elevated tumor markers were observed in 3 (12.5%) benign tumors and in 7 (77.8%) malignant tumors. In preoperative ultrasound investigation, cyst formation was identified in 4 benign tumors and solid tumor mass in 2 malignant tumors. A minimally invasive surgical approach was chosen in two patients, while open surgery was opted for in the rest. CONCLUSION Cyst formation, small tumor size and younger age at presentation were characteristic of benign tumors. Malignant tumors often presented with elevated tumor markers, a larger size and a solid consistency. Diagnostic dilemmas remain for both tumor groups due to the different tumor types and the heterogeneity of presentation.

Analysis of 347 kindergarten-related injuries

While it has been shown that non-parental childcare is associated with a reduced risk for unintentional injuries, a considerable number of accidents in kindergartens do result in severe injuries. We have collected data on the behavioral and environmental aspects of accidents that occurred in kindergartens in Austria with the aim of determining possible prevention measures. Included in the study were all kindergarten-related injuries (347) from among 21,582 pediatric trauma cases treated in a 22-month period in Graz, Austria. Kindergarten-related injuries that were treated during the same period at six participating hospitals located throughout Austria were used for comparision. A questionnaire was completed at first attendance, and additional information was achieved by interviews with the parents and kindergarten teachers. Only the 347 kindergarten accidents that occurred in Graz were analyzed in detail. Half of the injuries occurred in an outdoor environment (outside), even though most of the time was spent indoors. Boys were more frequently involved in accidents than girls (male:female = 3:2). We identified seasonal and circadian differences, with most children being injured during the first 2 months of attendance (September and October), during the first 3 days of the week (Monday to Wednesday) and in the hour before and after lunch, respectively. Of the 347 accidents analyzed, 24% resulted in serious injury, and injuries occurring outdoors were more severe than those occurring indoors. Most parents felt that the accidents were unpreventable (47%), while 18% stated that improved supervision may have prevented the accident. Kindergarten accidents in Austria still result in a significant number of severe injuries. Kindergarten injuries were related to gender, season, time of day and location. Our results indicate the necessity of a continuous child safety training program that involves the participation of all teachers in day-care functions.

Iatrogenic ulnar nerve injury after pin fixation and after antegrade nailing of supracondylar humeral fractures in children.

Background and purpose Ulnar nerve injury may occur after pinning of supracondylar fractures in children. We describe the outcome and compare the rates of iatrogenic injuries to the ulnar nerve in a consecutive series of displaced supracondylar humeral fractures in children treated with either crossed pinning or antegrade nailing. Methods Medical charts of all children sustaining this fracture treated at our department between 1994 and 2009 were retrospectively reviewed regarding the mode of treatment, demographic data including age and sex, the time until implant removal, the outcome, and the rate of ulnar nerve injuries. Results 503 children (55% boys) with an average age of 6.5 years sustained a type-II, type-III, or type-IV supracondylar fracture. Of those, 440 children were included in the study. Antegrade nailing was performed in 264 (60%) of the children, and the others were treated with crossed pins. Iatrogenic ulnar nerve injury occurred in 0.4% of the children treated with antegrade nailing and in 15% of the children treated with crossed pinning. After median 3 (1.6–12) years of follow-up, the clinical outcome was good and similar between the 2 groups. Interpretation Intramedullary antegrade nailing of displaced supracondylar humeral fractures can be considered an adequate and safe alternative to the widely performed crossed K-wire fixation. The risk of iatrogenic nerve injury after antegrade nailing is small compared to that after crossed pinning.

Post-traumatic coxa vara in children following screw fixation of the femoral neck

Background and purpose The rare displaced fractures of the femoral neck in children need accurate reduction and rigid fixation. The implants commonly used for internal fixation in children are pins or screws. We evaluated the long-term outcome in children who sustained fractures of the proximal femur that were treated by screw fixation. Patients and methods All 22 children (mean age 12 (5–16) years) with fractures of the femoral neck that were treated with screw fixation (mean 2.4 (1–3) screws) at our department between 1990 and 2006 were evaluated. For measurement of outcome, the Harris hip score (HHS) was used and the development of post-traumatic coxa vara was assessed from the difference in the neck-shaft angle postoperatively and at the latest follow-up examination, after mean 4 (2–15) years. Results A loss of reduction was observed in 12 patients. There was a statistically significant correlation between the HHS and the changes in the neck-shaft angle. Interpretation Loss of reduction was found in more than half of the children. Screw fixation cannot be recommended for the treatment of femoral neck fractures in children due to a substantial number of post-traumatic coxa vara.
