Fractures of the proximal radius in children: management and results of 100 consecutive cases.

INTRODUCTION: Pediatric radial neck and head fractures are rare, accounting for only 1% of all fractures in children. The aim of this study is to describe the management and results of the respective fracture types and different injury characteristics. MATERIALS AND METHODS: This study performs a retrospective data analysis of 100 consecutive patients with a fracture of the proximal radius treated in a single high-volume pediatric trauma center. RESULTS: One hundred patients [mean age 7.5 years (1-15)] were documented with a fracture of the proximal radius between 3/2011 and 12/2019. The gender distribution was 62 girls and 38 boys. Twenty-seven patients had concomitant injuries. Conservative treatment was performed in 63 patients (Judet I = 27; II = 30; III = 6; Mason I = 2) using an above-the-elbow cast for 21 days (6-35). Surgical treatment was performed in 37 patients (Judet II = 3; III = 22; IV = 5; V = 7) using elastic stable intramedullary nailing (ESIN). Open reduction was necessary in five cases, and additional immobilization was performed in 32 cases. Six complications occurred: loss of implant stability (n = 2), healing in malalignment, pseudarthrosis, radioulnar synostosis, and a persisting hypoesthesia at the thumb. As a result, two ESIN osteosynthesis were revised, and one radial head resection was performed. Loss of movement was seen in 11% of cases, overall Mayo elbow performance index (MEPI) was 99.8 (90-100), and none of the patients experienced negative impacts on activities of daily life. CONCLUSIONS: Proximal radial fractures occur predominately without dislocation. Good results are obtained with conservative treatment throughout. In cases with displacement exceeding growth-related correction, ESIN is the undisputed treatment of choice. Open surgery and long immobilization periods should be avoided whenever possible.

Surgical treatment of children with total colonic aganglionosis: functional and metabolic long-term outcome.

BACKGROUND: Total colonic aganglionosis (TCA) is a rare variant of Hirschsprung's disease occurring in 3-10% of the cases. Only few studies reported the long-term clinical and metabolic outcomes of patients with TCA. The aim of this study was to evaluate the functional and metabolic long-term outcomes of children undergoing surgical treatment for TCA. METHODS: A 15-year retrospective study was performed. Blood chemistry tests and stool analysis performed at the last follow-up visit were recorded. Height and weight development were assessed using the corresponding percentiles for age. Faecal continence and quality of life were evaluated using a detailed questionnaire. RESULTS: Eleven patients were included in the study. The median age at surgery was 6 months (range: 3-72 months). After histological confirmation, all patients underwent a total colectomy. Ileoanal anastomosis (n = 6), ileorectal anastomosis (n = 1), J-pouch (n = 1) and Duhamel procedure (n = 3) were performed. Temporary ileostomy was closed after a median of 8 weeks in 10/11 patients. After a median follow-up of 78 months (range: 27-199 months), all evaluated patients were continent. Height and weight were appropriate for age in only 5 patients. Vitamin B12 and folic acid serum levels were normal in all examined patients. Ten patients had normal hemoglobin serum levels. Seven patients had low transferrin saturation in serum. Hemoccult tests were negative in all examined patients. Despite complex postoperative courses in some cases, patients and parents showed good overall satisfaction in terms of quality of life. CONCLUSION: The majority of patients reported a good quality of life. This can result from the adaptation of the patients to certain disease states. The failure to thrive seems to be related with the extent of aganglionosis. The inclusion of these patients in interdisciplinary long-term follow-up care, in which pediatric surgeons, gastroenterologists, and dieticians are involved, is essential.

Elevated intrathoracic CO2 pressure during thoracoscopic surgery decreases regional cerebral oxygen saturation in neonates and infants-A pilot study.

BACKGROUND: Intraoperative hypercapnia and acidosis are risk factors during thoracoscopy in neonates and infants. METHODS: In a prospective pilot study, we evaluated the effects of thoracoscopy in neonates and infants on cerebral microcirculation, oxygen saturation, and oxygen consumption. Regional cerebral oxygen saturation and blood flow were measured noninvasively using a new device combining laser Doppler flowmetry and white light spectrometry. Additionally, cerebral fractional tissue oxygen extraction and approximated oxygen consumption were calculated. Fifteen neonates and infants undergoing thoracoscopy were studied using the above-mentioned method. The chest was insufflated with carbon dioxide with a pressure of 2-6 mm Hg. Single lung ventilation was not used. As control group served 15 neonates and infants undergoing abdominal surgery. RESULTS: Data are presented as median and range. The 95% confidence intervals for differences of means (95% CI) are given for the mean difference from baseline values. We observed a correlation between intrathoracic pressure exceeding 4 mm Hg and transient decrease in regional cerebral oxygen saturation of 12.7% (95% CI: 9.7-17.2, P<.001). Peripheral oxygen saturation was normal at the same time. Intraoperative increase in arterial paCO2 (median maximum value: 48.8 mm Hg, range: [36.5-65.4]; 95% CI: -16.0 to -3.0, P=.002) and decrease in arterial pH (median minimum value: 7.3, range: [7.2-7.4]; 95% CI: 0.04-0.12, P=.008) were observed during thoracoscopy with both parameters recovering at the end of the procedure. Periods of regional cerebral oxygen saturation below 20% from baseline were significantly more frequent during thoracoscopy as compared to the control group (median maximum value: 1.3%min/h, range: [0.0-66.2] vs median maximum value: 0.0%min/h, range: [0.0-4.0]; 95% CI: -16.6 to -1.1, P=.028). CONCLUSION: We suggest that thoracoscopic surgery in neonates and infants, although generally safe, may be associated with a decrease in regional cerebral oxygen saturation correlating with the applied intrathoracic pressure. According to our data an inflation pressure >4 mm Hg should be avoided during thoracoscopic surgery.

Late-onset volvulus without malrotation in extremely preterm infants--a case-control-study.

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 malrotation in preterm infants. METHODS: Retrospective, single-centre case-control study (2007-2011). For every index patient, five infants of similar gestational age, birth weight and birth year were evaluated. Additionally, all 9 cases of necrotising enterocolitis occurring during the above period were evaluated. Data are presented as median (interquartile range). RESULTS: Five extremely premature infants suffering from volvulus without malrotation were identified (gestational age at birth 24.4 (23.6-25.5) weeks, birth weight 480 (370-530) g). All were small for gestational age and female; three out of five died. Volvulus occurred several weeks after birth, whereas necrotising enterocolitis occurred significantly earlier. Beyond that, no striking differences in clinical or laboratory presentation of volvulus without malrotation and necrotising enterocolitis were found. Infants with volvulus had significantly more frequent manipulations with rectal tubes for flatulence, but there were no differences in the frequency of enemas, abdominal massage or defecation. In infants with volvulus, nasal high-frequency oscillation was used more frequently for respiratory support, and PEEP-level tended to be higher. CONCLUSIONS: In extremely premature infants volvulus without malrotation represents a life-threatening event that occurs typically several weeks after birth with an acute abdomen and seems to affect predominantly girls. Infants requiring intensive non-invasive respiratory support might be at highest risk.

Treatment of unstable forearm fractures at the metaphyseal-diaphyseal junction in children: antegrade ESIN vs. transepiphyseal intramedullary K-wire fixation.

BACKGROUND: Treatment of unstable forearm fractures in the metaphyseal-diaphyseal junction (MDJ) zone is still a matter of debate. Major drawbacks of all types of fixations include either invasiveness, technical impracticality, or lack of acceptance by patients. This study reports results after antegrade ESIN (a-ESIN) compared to transepiphyseal intramedullary K-wire (TIK) for unstable MDJ forearm fractures. METHODS: The MDJ of the forearm was defined as the square over the joints of both forearm bones subtracted with the square over the metaphysis of the radius alone. The data of 40 consecutive patients < 16 years of age who were treated either by a-ESIN (later treatment period) or TIK (early treatment period) for an unstable MDJ forearm fracture at a single high-volume pediatric trauma center were retrospectively analyzed. RESULTS: The average age was slightly lower in the first group (TIK = 7.42 years; a-ESIN = 10.5 years). An additional ulna fracture was found in 50% of cases and was treated with a classic antegrade ESIN in 10/20 (TIK) and 6/20 cases (a-ESIN). Additional plaster cast immobilization was performed in all cases with TIK and in three cases with a-ESIN. After TIK, no complication, malalignment, or functional limitation occurred. After a-ESIN, 19/20 patients had an event-free course with stable retention and healing without axial malalignment. In one case, a temporary sensor dysfunction occurred. The same patient suffered a refracture two months after the original trauma, which required a closed reduction. Metal removal was performed after 84 days (TIK) and 150 days (a-ESIN). The outcome in all patients was good. CONCLUSION: Both a-ESIN and TIK are minimally invasive procedures that are technically easy to perform. Both methods are safe and lead to a complete restoration of the forearm's range of motion. The decisive advantage of a-ESIN is the possibility of postoperative immobilization-free rehabilitation.

Successful on-ECLS Repair of CDH and Omphalocele in a Newborn.

Both congenital diaphragmatic hernias (CDHs) and omphaloceles show relevant overall mortality rates as individual findings. The combination of the two has been described only sparsely in the literature and almost always with a fatal course. Here, we describe a term neonate with a rare high-risk constellation of left-sided CDH and a large omphalocele who was successfully treated on extracorporeal life support (ECLS). Prenatally, the patient was diagnosed with a large omphalocele and a left CDH with a lung volume of ∼27% and an observed to expected lung-to-head ratio of 30%. Due to respiratory insufficiency, an ECLS device was implanted. As weaning from ECLS was not foreseeable, the female infant underwent successful surgery on ECLS on the ninth day of life. Perioperative high-frequency oscillatory ventilation and circulatory and coagulation management under point-of-care monitoring were the main anesthesiological challenges. Over the following 3 days, ECLS weaning was successful, and the patient was extubated after another 43 days. Surgical treatment on ECLS can expand the spectrum of therapy in high-risk constellations if potential risks are minimized and there is close interdisciplinary cooperation.

Thoracoscopic Resection of Lung Nodules following CT-Guided Labeling in Children and Adolescents with Solid Tumors.

Resection of lung metastases in children with solid tumors is regularly hampered by limited intraoperative detectability and relevant operative trauma of the open surgical access. The aim of this study was to analyze thoracoscopic resection of lung metastases in children following CT-guided labeling with coil wires. We retrospectively analyzed data of children and adolescents undergoing this approach at our institution between 2010 and 2022 with regard to technical aspects as well as surgical and oncological data. Within this period, we performed this procedure on 12 patients wherein we resected 18 lesions (1-5 per patient). The median age of patients was 178 months (51-265). The median duration of coil wire placement was 41 min (30-173) and the median surgery time was 53 min (11-157). No conversions were necessary and no intraoperative complications occurred. Complete microscopic resection (R0) was achieved in all labeled lesions and malignant tumor components were found in 5/12 patients. Our study shows that with a careful patient selection, thoracoscopic resection of lung metastases after coil wire labeling is a safe and reproducible procedure in children. Using this approach, lesions that are expected to have a reduced intraoperative detectability during open surgery become resectable. Patients benefit from the minimally invasive surgical access and reduced operative trauma.

Implant removal associated complications after ESIN osteosynthesis in pediatric fractures.

PURPOSE: ESIN (elastic stable intramedullary nailing) is considered the gold standard for various pediatric fractures. The aim of this study was to analyze the incidence and type of complications during or after TEN (titanium elastic nail) removal. METHODS: A retrospective data analysis was performed. Metal removal associated complications and preoperative extraosseous length/outlet angle of TENs as possible causes of complications were assessed. RESULTS: The complication rate in 384 TEN removals was 3.1% (n = 12). One major complication (rupture of M. extensor pollicis brevis) was documented. One refracture at the forearm occurred, however, remodeling prior TEN removal was completed. Ten minor complications were temporary or without irreversible restrictions (3 infections, 5 scaring/granuloma, 2 temporary paraesthesia). In 38 cases (16 forearms, 10 femora, 9 humeri, 3 lower legs), intra-operative fluoroscopy had to be used to locate the implants. In patients with forearm fractures, extraosseous implant length was relatively shorter than in cases without fluoroscopy (p = 0.01), but outlet angle of TENs was not significantly different in these two groups (28.5° vs 25.6°). In patients with femur fractures, extraosseous implant length and outlet angle were tendentially shorter, respectively, lower, but this did not reach statistical significance. CONCLUSION: Removal of TENs after ESIN is a safe procedure with a low complication rate. Technically inaccurate TEN implantation makes removal more difficult and complicated. To prevent an untimely removal and patient discomfort, nail ends must be exactly positioned and cut. Intraoperative complications may be minimized with removal of TENs before signs of overgrowth. EVIDENCE: Level III, retrospective.

Results after skin traction for femur shaft fractures in children below the age of four years.

PURPOSE: Nonsurgical management has been identified as the treatment of choice for femoral shaft fractures in children below four years of age. For various reasons, the surgical approach has become increasingly popular in recent years. The aim of this study is to report results after vertical skin traction and analyze the benefits of this technique as well as to point out advantages compared with surgery in this age group. METHODS: The authors performed a retrospective data analysis, including all patients with femoral shaft fractures below the age of four who were treated with vertical skin traction at our institution between January 2006 and December 2016. RESULTS: Skin traction for a femoral shaft fracture was performed for 36 patients (mean age 1.6 years; 1 day-3.5 years). The mean duration of traction was 18.5 days (14-30). Complications included soft tissue affections (n = 5), which all healed spontaneously. Consolidation was observed in all fractures. Initial axial deviations and shortening did not change during traction until consolidation (p > 0.05), and no relevant torsion deformity occurred (p = 0.01). Patients gained full weight-bearing within 12.3 days (7-40) following end of traction. At the final follow-up, after a mean of 29.3 months (12-192), leg-length discrepancy (mean 7.1 mm; 5-20) was found on radiograms in nine cases, and axial deviations (mean 7.7°; 5-25) were documented in seven cases. None of the patients had limitations in daily activities or sports. CONCLUSION: Skin traction is a technically easy, safe, and non-invasive treatment modality for femoral shaft fractures in children below the age of four years. Strong results are obtained benefited from a high potential of growth-related correction, and in principle no anesthesia is needed. A prolonged hospitalization and socio-economic factors maintain the ongoing debate in comparison with the surgical approach. LEVEL OF EVIDENCE: Level III, retrospective.

Gastric Transposition for Repair of Long-Gap Esophageal Atresia: Indications, Complications, and Outcome of Minimally Invasive and Open Surgery.

BACKGROUND: Gastric transposition (GT) is a possible option for esophageal replacement in long-gap esophageal atresia (LGEA). The present study aims to report and compare indications and outcome of laparoscopic-assisted GT (LAGT) versus open (OGT) GT for LGEA repair. METHODS: Retrospective single-center analysis of all LGEA patients undergoing GT between 2002 and 2021. RESULTS: Thirty-one children with LGEA underwent GT. Of these, 19 underwent LAGT (mean weight at surgery 5.6 kg; mean age 167 days) and 12 underwent OGT (6.1 kg; 233 days). Indications for OGT were previous surgery (n = 7), associated severe cardiac malformations (n = 4), and a simultaneous resection of a choledochal cyst (n = 1). The conversion rate was 1. The two procedures (LAGT/OGT) differed in anesthetic time (308/350 min), duration of ventilation (5.1/5.3 days), hospital stay (34/32 days), and complications (22/15). None of the differences reached statistical significance. Outcome was also comparable: completely oral nutrition uptake in 66%/73%, slow weight gain in the low centiles in both groups, no patient developed dumping syndrome, symptomatic reflux was seen in 1 patient after OGT. CONCLUSION: In our cohort, LAGT for repair of LGEA provided similar outcomes as open surgery. The minimally invasive approach preserves thoracal structures, prevents additional thoracotomy or laparotomy, and is faster. To realize LAGT, a postpartal treatment concept including gastrostomy placement via a microincision to minimize adhesions is essential. The open surgical approach should be considered in cases of previous extensive surgical attempts of EA correction causing severe adhesions as well as associated anomalies or genetic syndromes causing hemodynamic instability.

Changes in the management of pediatric medial humeral epicondyle fractures with and without associated elbow dislocation.

Purpose The optimal management of medial humeral epicondyle fractures continues to be debated since decades. This single center study analyzes changes and optimizations of treatment over an observation period of 16 years and reports the results. Materials and Methods Retrospective analysis of all patients treated with a medial humeral epicondyle fracture between 2005 and 2020 at our institution. Results Ninety-six patients (mean 9.3 years, range 1 - 15) were included in the study. In 25 cases (26 %), the fracture was associated with an elbow dislocation. Most patients received surgical treatment (83.3 %), whereas 17.7 % were treated nonoperatively. Surgical treatment consisted of open reduction and fixation with compression screw (n = 44 steel, n = 2 absorbable), K-wire (n = 30), a combination of screw/K-wire (n = 2), or a PDS suture (n = 1). Compression screws have been used significantly more often in the latter half of the study period (p = 0.006). Patients were immobilized in a long arm cast for 29 days (range 11 - 50). Eleven surgically treated patients were early mobilized in an elbow orthosis. After a mean follow up of 7.6 months [2 - 61), Mayo elbow performance index (MEPI) outcome was excellent in all 96 patients. Loss of elbow movement (LOM) was found to be mild in 30 and moderate in 15 patients. LOM was found to be associated with surgical treatment (p = 0.001), and with concomitant elbow dislocations (p = 0.29). One pseudarthrosis occurred after conservative treatment. A persistence of ulnar nerve palsy or recurrent joint instability has not been described. Conclusion Most children with medial humeral epicondyle fractures nowadays undergo surgery. Screw osteosynthesis represents the increasingly preferred method in order to prevent joint instability or non-union, and to allow shorter immobilization duration. Overall results after medial epicondyle fractures are good.

Functional outcome after laparoscopic assisted gastric transposition including pyloric dilatation in long-gap esophageal atresia.

BACKGROUND/PURPOSE: Among the options for esophageal replacement in long-gap esophageal atresia (LGEA), gastric transposition (GT) is accessible for an endoscopic approach. Here we report a novel technique and functional results after laparoscopic-assisted gastric transposition (LAGT), including pyloric dilatation in patients with LGEA. METHODS: Retrospective analysis of 14 children undergoing LAGT. Surgical steps included the release of the gastrostomy, transumbilical ante-situ section of the stomach including pyloric balloon-dilation, and laparoscopically controlled transhiatal retromediastinal blunt dissection followed by LAGT for cervical anastomosis to the proximal esophagus. RESULTS: The median age at LAGT was 110 days (33-327 days), bodyweight 5.3 kg (3.1-8.3 kg). Operation time was 255 min (180-436 min); one conversion was necessary. The duration of ventilation was 4 days (1-14 days). Postpyloric feeding was started after 2 days, and oral feeding after 13 days. Complications were recurrent pleural effusion or pneumothorax and transient Horner syndrome or transient incomplete paresis of the recurrence nerve. After a median follow-up of 60 months (13-240 months), all children have a patent upper GI tract, show weight gain, and are fed without delayed gastric emptying, dumping, or reflux. Severe (n = 1) or mild (n = 2) anastomotic or pyloric (n = 5) stenosis was resolved with endoscopic dilatations. CONCLUSIONS: Functional outcome after LAGT in patients with LGEA is good. The laparoscopic retromediastinal dissection preserves thoracal structures and increases patients' safety. The technique of pyloric dilatation might also prevent dumping syndrome. TYPE OF STUDY: Case Series with no Comparison Group. LEVEL OF EVIDENCE: Level IV.

Epidemiological study on intestinal volvulus without malrotation in VLBW infants.

BACKGROUND: We conducted a monthly epidemiological survey in Germany to detect the prevalence of volvulus without malrotation (VWM) in very low birthweight (VLBW) infants and to identify factors for a better distinction between this rare and life-threatening event and other acute abdominal diseases in preterm infants. METHODS: Throughout 2014 and 2015, every paediatric department in Germany was asked to report cases of VWM in infants with birth weights <1500 g to the Surveillance Unit for Rare Paediatric Conditions in Germany. Hospitals reporting a case were asked to return an anonymised questionnaire and discharge letter. RESULTS: Of 36 cases reported, detailed information was submitted on 29, with 26 meeting entry criteria. With 9896 and 10 140 VLBW infants born in Germany in 2014 and 2015, respectively, we estimated a prevalence of 1.52/1000 VLBW infants for 2014 and 1.08/1000 in 2015. No specific early symptom could be determined. 10% died, and 21% of infants developed short bowel syndrome. Calculated from all verified VWM arise death in 8% and a short bowel syndrome in 15%. CONCLUSION: VWM is a rare source of acute abdomen in VLBW infants. No specific signs and symptoms potentially facilitating an early recognition of VWM could be found from this survey. Because the rates of death and short bowel syndrome are high, VWM should always be considered early in an acute abdomen in a VLBW infant.

Evaluation of a Pilot Project to Introduce Simulation-Based Team Training to Pediatric Surgery Trauma Room Care.

Introduction. Several studies in pediatric trauma care have demonstrated substantial deficits in both prehospital and emergency department management. Methods. In February 2015 the PAEDSIM collaborative conducted a one and a half day interdisciplinary, simulation based team-training course in a simulated pediatric emergency department. 14 physicians from the medical fields of pediatric surgery, pediatric intensive care and emergency medicine, and anesthesia participated, as well as four pediatric nurses. After a theoretical introduction and familiarization with the simulator, course attendees alternately participated in six simulation scenarios and debriefings. Each scenario incorporated elements of pediatric trauma management as well as Crew Resource Management (CRM) educational objectives. Participants completed anonymous pre- and postcourse questionnaires and rated the course itself as well as their own medical qualification and knowledge of CRM. Results. Participants found the course very realistic and selected scenarios highly relevant to their daily work. They reported a feeling of improved medical and nontechnical skills as well as no uncomfortable feeling during scenarios or debriefings. Conclusion. To our knowledge this pilot-project represents the first successful implementation of a simulation-based team-training course focused on pediatric trauma care in German-speaking countries with good acceptance.

ERCP in infants, children and adolescents is feasible and safe: results from a tertiary care center.

BACKGROUND: Indications for endoscopic retrograde cholangiopancreatography (ERCP) in children differ from adults. Paucity of data and concerns about potential lower effectiveness and more side effects limit its use even in high volume centers. We retrospectively analyzed indications, success rates, limitations, and side effects of ERCPs in children <18 years. METHODS: From January 2012 to March 2015, 54 ERCPs were performed in 31 children (median age 11 (0-17) years; median weight 22 (3.3-142.7) kg) with suspected choledocholithiasis (n = 13 interventions in 9 patients), post-transplantation anastomotic stenosis (10/4), malignancy (10/5), chronic pancreatitis (7/1), biliary atresia (6/6), anomaly (2/2), leak (4/3), or primary sclerosing cholangitis (PSC) (2/1). All patients were followed up as inpatients. RESULTS: Thirty-six therapeutic and 18 diagnostic procedures were performed by adult ERCP expert endoscopists. Successful intervention was achieved in 90.7% of cases. Failed cannulation (n = 4) was associated with lower body weight (p = 0.023). In children younger than 1 year, ERCP was significantly more often diagnostic than in patients >1 year (p < 0.001). In three of six infants with suspected atresia, surgical exploration was avoided. Five complications were recorded (9.3%), and included four episodes of mild pancreatitis (7.4% post-ERCP pancreatitis (PEP) rate) and one cholangitis in PSC. A trend towards a protective effect of pancreatic stents on PEP was observed. All complications were managed conservatively. No complications were attributed to mechanical stress on the gastrointestinal tract. CONCLUSIONS: ERCP in newborns, infants, and adolescents can be safely performed with high technical and clinical success. Endoscopists must be aware of differing spectrum of pediatric diseases. Failed cannulation was associated with lower body weight of young children. Complications were similar to rates reported in adults.

Experiences and challenges of thorcoscopic lung surgery in the pediatric age group.

BACKGROUND: We report a single-center study of minimally invasive thoracoscopic lung surgery with pediatric patients. METHODS: We performed a retrospective analysis of patients who underwent thoracoscopic lung surgery between 2004 and 2013. The procedures were divided into anatomic and non-anatomical lung resections. RESULTS: Seventy-six patients with a mean age of 6.5 years (range: 7 days-17 years) and a mean weight of 11 kg (range: 2.6-56.0 kg) received thoracoscopic lung surgery for tumor metastases (n = 20), sequestration/congenital adenomatoid malformation (19), cysts (12), aspergillomas (7), bullae (5), middle lobe syndrome (3), bronchiectasis (3), emphysema (2), and other reasons (5). Twenty-nine anatomical lung resections (Group I: lobectomies, segmentectomies) and 47 non-anatomical lung resections (Group II: wedge resections, lung tissue-sparing surgery) were performed. In 6 cases, preoperative CT-guided coiling was used to localize the lung lesions. Specimen removal was achieved using a widened (2 cm) trocar site. The operating times of Group I patients were longer compared than those of Group II patients (means: 154 and 68 min, respectively); conversion rates (8 versus 2), chest tube insertion rates (100% versus 51%), and postoperative ventilation (48% versus 13%) also differed. CONCLUSION: Thoracoscopic anatomical lung resections appear to be safe and effective in infants and children. In congenital lung diseases, the key to success is the intraoperative destruction of space-occupying lesions. Limitations exist in cases with infectious adhesions. Non-anatomical lung resections are technically easier and should remain standard in pediatric surgery. Limitations exist in cases of metastases, which are deep within the parenchyma and are not visible on the lung surface.

Chest wall repair in Poland syndrome: complex single-stage surgery including Vertical Expandable Prosthetic Titanium Rib stabilization--a case report.

Various surgical techniques have been described for repair of chest wall defects in Poland syndrome. We describe the case of a 16-year-old boy who underwent autologous rib transposition after sternal osteotomy. Chest wall stabilization was achieved using a combination of K-wires and Vertical Expandable Prosthetic Titanium Rib (Synthes GmbH, Freiburg, Germany). Reconstruction of the soft tissue defect was accomplished by combined latissimus dorsi muscle flap and Permacol patch (Covidien Deutschland GmbH, Neustadt, Germany). This approach might be considered an effective 1-stage treatment option of this condition in postpubescent boys.

Treatment of benign bone defects in children with silicate-substituted calcium phosphate (SiCaP).

BACKGROUND: In children with benign bone defects, various treatment options are recommended. Whether these defects should be curetted, osteosynthetically stabilized and/or filled with allogenic or synthetic bone material is still a matter of controversy. METHODS: The reported study presents preliminary results of five children with benign bone lesions of the lower extremity. Curettage and filling of the defect with a commercially available silicate-substituted calcium phosphate (SiCaP) (Actifuse® by ApaTech Ltd., Elstree, United Kingdom) was performed. Patients were followed-up in the outpatient clinic. The healing process was assessed according to the clinical and radiological criteria. RESULTS: Clinical and radiological follow-up showed uneventful healing without intraoperative and short-term complications. All patients were capable of full weight bearing after a few weeks and currently did not experience any decreased range of movement among adjacent joints. Growth disturbances did not occur. In all patients increasing cancellous bone reconstruction of the defect, without signs of osteolysis could be shown radiologically. CONCLUSION: SiCaP represents a good and safe alternative to hitherto existing therapies in the management of defined symptomatic benign bone defects in the pediatric age group.

Elastic stable intramedullary nailing (ESIN) of pediatric metacarpal fractures: experiences with 66 cases.

INTRODUCTION: Elastic stable intramedullary nailing (ESIN) is the first-choice surgical technique for stabilizing various pediatric diaphyseal and selected metaphyseal fractures of the long bones. This technique has increasingly been applied in fractures of the small bones. Here, we report experiences with ESIN in displaced fractures of the metacarpals in children. PATIENTS AND METHODS: Retrospective data analysis of metacarpal fractures in children stabilized by ESIN in three pediatric trauma centers between 2003 and 2009. Indication for intervention was total displacement or axial deviation >10 degrees in the frontal plane and/or >30 degrees in the sagittal view. RESULTS: A total of 66 cases of metacarpal fractures (51 right hand and 12 left hand) treated by ESIN were found in 63 children (mean age 13.3 years; range 4.0 to 16.1) over the study period. Of these, 55 fractures affected metacarpal 5, 6 fractures affected metacarpal 4, 3 fractures affected metacarpal 1, and 2 fractures occurred at metacarpal 2. Mean operating time was 21 minutes (range 5 to 54), titanium elastic nails were used with a diameter of 1.5 mm (n = 23), 2.0 mm (n = 42), and 2.5 mm (n = 1). Single ESIN implantation was performed in 63 cases; in 3 cases, two nails were implanted. Eleven patients received additional immobilization due to nondisplaced additional fractures of the phalanx (n = 2) or for analgetic treatment (n = 9). Five complications were registered (7.6%). In two cases recurrent fracture dislocation occurred, one of them requiring revision of the osteosynthesis. In other two cases irritation of the extensor tendons occurred, one of them requiring secondary tendon plasty. One persisting cutaneous hyposensibility after ESIN of a metacarpal 5 fracture was reported. All fractures healed uneventfully and metal removal was performed after a mean of 92 days (range 31 to 104). After a mean follow-up of 26 months (range 2 to 74), all patients had full range of movement and cosmetic results were described as good and satisfactory by all patients. CONCLUSION: ESIN of the metacarpals is a safe, minimally invasive, and technically easy option in displaced fractures that warrant surgical intervention achieving excellent long-term results. Complications occurred when technical aspects to obtain stability were neglected or tendons and nerves of the hand had been injured. Stabilizing fractures of metacarpal 1 is technically challenging when compared with fractures of metacarpals 2 to 5.
