Abstract
BACKGROUND Metal bar removal after the Nuss repair procedure is prone to be cancelled in cases of operating time shortages due it being suitable to be postponed without harming patients. Consequently, planning operation times as exactly as possible could be one solution. OBJECTIVE Statistical modelling of operation times of metal bar removal after Nuss repair using the prespecified independent predictors of age, sex, intraoperative complications, and number of implanted metal bars. MATERIAL AND METHODS We included all patients whose operation notes included an operation time, which was modelled via linear regression and subject to internal validation via bootstrap. Exploratory analyses also consisted of the surgeon's experience, the number of stabilizers, the body mass index, and preceding re-do surgery for bar dislocation. RESULTS We included 265 patients (14% ♀) with a median age of 19 years (interquartile range 17-20 years), of whom 81% had 1 and 17% had 2 metal bars removed. The prespecified regression model was statistically significant (likelihood ratio 56; df = 5; P < 0.001) and had a bias corrected R2 of 0.148. Patient age influenced operation times by 2.1min per year of life (95% confidence interval 1.3-2.9min; P < 0.001) and 16min per explanted metal bar (95% confidence interval: 10-22min; P < 0.001). CONCLUSION The patient-specific factors of age and the number of explanted metal bars influenced the operation times and can be included into scheduling operation times.

Abstract
BACKGROUND Incidences of pilonidal sinus disease are rising. Guidelines rarely consider children and adolescents and evidence for their treatment is rare. The literature is divided on the choice of the preferable surgical procedure. Therefore, we aimed to assess recurrences and complications following different treatment approaches in our multi-centric cohort. METHODS We retrospectively assessed all patients treated for pilonidal sinus disease in the paediatric surgical departments of Bonn and Mainz between 01/01/2009 and 31/12/2020. Recurrences were defined according to the German national guidelines. The pre-specified analysis via logistic regression included the operative approach, age, sex, use of methylene blue, and obesity as independent predictors. RESULTS We included 213 patients, of which 13.6% experienced complications and 16% a recurrence. Median time to recurrence was 5.8 months (95% confidence interval: 4.2-10.3), which was slightly higher in children than adolescents (10.3 months, 95% confidence interval: 5.3-16.2 vs. 5.5 months, 95% confidence interval: 3.7-9.7). None of the investigated procedures, excision and primary closure, excision and open wound treatment, pit picking, and flap procedures had a decisive advantage in terms of complications or recurrence. Of the independent predictors, only obesity was associated to complications (adjusted odds ratio: 2.86, 95% confidence interval: 1.05-7.79, P = 0.04). CONCLUSIONS We did not find a difference between the investigated procedures, but our analysis is limited by the small sample size in some subgroups. Our data corroborates that recurrences in paediatric pilonidal sinus disease occur early. Factors linked to these differences remain unknown.

Abstract
IntroductionThere is a paucity of clinical data on pediatric epigastric hernias despite them accounting for up to 6% of all hernia repairs in children. We aimed to provide additional data to supplement those 117 cases of a recent systematic review and to further clarify the role of ultrasound in diagnosing pediatric epigastric hernia.MethodsWe retrospectively included all 60 patients treated for epigastric hernias in children in two tertiary pediatric surgical departments within 12 years. Associations were tested via point-biserial correlation analyses.ResultsEpigastric hernias primarily affected preschool children with a median age of 39 months. The vast majority of patients (88%) presented with swelling that was occasionally (30%) accompanied by pain. Fascial defects could be found during clinical examination in 45% of patients with a median size of 5 mm (95% CI 3 to 10). Smaller defects were less likely to be palpable (r=−0.44, 95% CI −0.08 to −0.7, p=0.021). Likewise, ultrasound was used more frequently with smaller fascial defect sizes (r=−0.51, 95% CI −0.16 to −0.74, p=0.007). Laparoscopic repair was used in 11 patients (19%) and more often (4/11) in combination with another simultaneous procedure than open repair (11/48).ConclusionsEpigastric hernias are primarily a condition of the preschool child. Ultrasound can be beneficial if the diagnosis cannot be made clinically; otherwise, it is abdicable if it does not change the management of the patient’s epigastric hernia. Laparoscopic repairs might be beneficial for children with multiple defects or simultaneous procedures.

Abstract
BACKGROUND The COVID-19 pandemic has changed medical teaching worldwide. Digital teaching and examinations are successful for cognitive learning objectives, whereas practical skills had to be carried out predominantly in person under strict hygiene standards. AIM This study presents the opportunities and challenges of using a presence objective structured clinical examination (OSCE) at a distance with digital support. METHOD Following surgical practical teaching an OSCE was conducted in presence, where students demonstrated practical skills in one room while the examiners were connected via videoconference from another room. Students were surveyed about the OSCE and sustained learning via a standardized online questionnaire after completion of the surgical teaching. Additionally, examiners were surveyed on their experiences. RESULTS In the online survey 40 students participated (25% of n = 157 students contacted) and 36 completed questionnaires were analyzed. Overall, the implementation of an OSCE even under pandemic conditions was perceived as very positive by the students (92% of students n = 33). In particular, the acquisition of practical skills was rated as very high. For 78% (n = 28) of the students, the acquisition of competencies through the practical examination was particularly sustainable. The vast majority of students and examiners felt safe regarding infection control because of the hygiene concept (92%, n = 33). Overall, 80 students achieved grade 1 (51%), 71 students grade 2 (45.2%) and 6 students grade 3 (3.8%) (grade 1 = very good, grade 6 = very bad). CONCLUSION Practical examinations are essential for checking practical learning objectives and can be implemented at a distance with a well-developed hygiene concept and digital support.

Abstract
INTRODUCTION Esophageal atresia (EA) is a rare malformation that often requires a series of procedures, including surgical primary anastomosis, staged repair, and endoscopic procedures. Actual numbers and trends in interventions and variety in treatment strategies remain unclear. MATERIALS AND METHODS Data from the German federal bureau of statistics containing all EA-related inpatient procedures encoded from 2005 until 2018 were analyzed for children during the first year of life. The sum of esophageal anastomoses and replacements was used to calculate an estimate of incidence of EA. RESULTS Over 14 years, 12,627,888 inpatient cases were recorded in infants in Germany. The mean incidence of EA was 1 per 4,217 live births. On average, 163.3 (95% confidence interval [CI]: 150.8-176.1) esophageal anastomoses, 11.2 (95% CI: 8.7-13.7) esophageal lengthening procedures, and 6.7 (95% CI: 5.42-8.00) esophageal replacements were recorded annually. Overall, 187.8 (95% CI: 147.1-200.4) endoluminal treatments (ballon dilatation, bougienage, stent placement, or injection) were performed per 100 anastomoses. Over the years, bougienage was increasingly replaced by ballon dilatation as primary treatment. Boys had a significantly higher number of esophageal procedures than girls, but the incidence of endoscopic treatments in relation to anastomoses was the same for both genders. CONCLUSION The low incidence of EA in relation to a relatively large number of units treating those patients in Germany may pose challenges for maintaining competency and training of all specialists involved. The number of esophagoscopic treatments for esophageal stricture per anastomosis is lower than previously estimated.

Abstract
High voltage burn injuries are rare in the pediatric age group, but can lead to devastating, severe sequelae. We present the cases of two young girls who suffered high voltage burn injuries due to direct contact with overhead power lines. Both patients came from difficult psychosocial backgrounds. The injuries resulted in severe long-term consequences and functional deficits.

Abstract
Background: Patients with esophageal atresia (EA) often experience physical limitations. With increasing survival over the past decades, the focus in care shifted toward improving the long-term quality of life. We performed validated testing fitness and motor skills in children born with EA. Methods: Patients with EA were evaluated using the standardized Kinderturntest Plus/ Deutscher Motorik Test after caregiver's written consent. Test scores range from 1 to 5 (compared to an age- and gender matched standard population). Caregivers completed an online-questionnaire on patient history. Results: Seventeen patients (median age 7 [3-12] years) were included. Comorbidities were prematurity (54%), birth weight <1,500 g (23%), congenital heart disease (46%), developmental delay (38%), skeletal deformity (23%), and anorectal malformation (15%). The mean test score was significantly lower in children with EA (2.19) compared to a control group matched for age, gender, body weight, and -height, (2.75, p = 0.04), and the general population (3, p = 0.00). Distribution of patient scores was below the 41st performance percentile for gender and age in 54-63%. Caregivers identified notable deficits of strength and endurance. All but one patient complained about discomfort during physical exercise, most commonly respiratory distress (46%) and gastroesophageal reflux symptoms (31%). Notably, 93% of subjects participated in regular school physical education classes, and 86% participated regularly in additional organized sporting activities. Conclusions: Children after EA repair have decreased physical fitness and impaired locomotor function compared to the general population on a standardized test. Physical discomfort is frequent during exertion. To avoid demotivation, locomotor skill should be promoted at each individual's comfortable level. The study was registered at www.researchregistry.com (No. 3707).
