RESUMEN
Introduction: Long survivors after childhood cancer are increasing thanks to oncological improvements. Their quality of life and fertility-sparing should be considered in the early phases of each oncological pathway. Cryopreservation of ovarian tissue removed before starting gonadotoxic therapies is the only fertility sparing procedure available for prepubertal children affected by cancer and it does not affect the timing of the start of the treatment. Materials and methods: The present study shows the surgical and clinical outcomes following laparoscopic ovarian tissue collection (LOTC) for a total of 311 patients aged between 0 and 17 years old from four different European Centers. Results: Only two major complications were reported according to the Clavien Dindo classification (0.6%). Discussion: LOTC can be considered a safe procedure.
RESUMEN
BACKGROUND: Liver transplantation is the state-of-the-art curative treatment for end-stage liver disease. Imaging is a key element in the detection of intraoperative and postoperative complications. So far, only limited data regarding the best radiological approach to monitor children during liver transplantation is available. OBJECTIVE: To harmonize the imaging of pediatric liver transplantation, the European Society of Pediatric Radiology Abdominal Taskforce initiated a survey addressing the current status of imaging including the pre-, intra- and postoperative phase. This paper reports the responses related to intraoperative imaging. MATERIALS AND METHODS: An online survey, initiated in 2021, asked European centers performing pediatric liver transplantation 48 questions about their imaging approach. In total, 26 centers were contacted, and 22 institutions from 11 countries returned the survey. RESULTS: Intraoperative ultrasound (US) is used by all sites to assess the quality of the vascular anastomosis in order to ensure optimal perfusion of the liver transplant. Vessel depiction is commonly achieved using color Doppler (95.3%). Additional US-based techniques are employed by fewer centers (power angio mode, 28.6%; B-flow, 19%; contrast-enhanced US, 14.3%). Most centers prefer a collaborative approach, with surgeons responsible for probe handling, while radiologists operate the US machine (47.6%). Less commonly, the intraoperative US is performed by the surgeon alone (28.6%) or by the radiologist alone (23.8%). Timing of US, imaging frequency, and documentation practices vary among centers. CONCLUSION: Intraoperative US is consistently utilized across all sites during pediatric liver transplantation. However, considerable variations were observed in terms of the US setup, technique preferences, timing of controls, and documentation practices. These differences provide valuable insights for future optimization and harmonization studies.

BACKGROUND: Liver transplantation is the state-of-the-art curative treatment for end-stage liver disease. Imaging is a key element in the detection of postoperative complications. So far, limited data is available regarding the best radiologic approach to monitor children after liver transplantation. OBJECTIVE: To harmonize the imaging of pediatric liver transplantation, the European Society of Pediatric Radiology Abdominal Taskforce initiated a survey addressing the current status of imaging including the pre-, intra-, and postoperative phases. This paper reports the responses related to postoperative imaging. MATERIALS AND METHODS: An online survey, initiated in 2021, asked European centers performing pediatric liver transplantation 48 questions about their imaging approach. In total, 26 centers were contacted, and 22 institutions from 11 countries returned the survey. RESULTS: All sites commence ultrasound (US) monitoring within 24 h after liver transplantation. Monitoring frequency varies across sites, ranging from every 8 h to 72 h in early, and from daily to sporadic use in late postoperative phases. Predefined US protocols are used by 73% of sites. This commonly includes gray scale, color Doppler, and quantitative flow assessment. Alternative flow imaging techniques, contrast-enhanced US, and elastography are applied at 31.8%, 18.2%, and 63.6% of sites, respectively. Computed tomography is performed at 86.4% of sites when clarification is needed. Magnetic resonance imaging is used for selected cases at 36.4% of sites, mainly for assessment of biliary abnormalities or when blood tests are abnormal. CONCLUSION: Diagnostic imaging is extensively used for postoperative surveillance of children after liver transplantation. While US is generally prioritized, substantial differences were noted in US protocol, timing, and monitoring frequency. The study highlights potential areas for future optimization and standardization of imaging, essential for conducting multicenter studies.

BACKGROUND: Image-guided intussusception reduction has been practised internationally for many decades. The use of different modalities, delayed repeat attempts, and sedation/anaesthesia are unknown. OBJECTIVE: To survey the practice of image-guided intussusception reduction. MATERIALS AND METHODS: A 20-point questionnaire created by the European Society of Paediatric Radiology (ESPR) Abdominal Imaging Taskforce was distributed via the ESPR members' mailing list and shared on social media between 28 March and 1 May 2023. RESULTS: There were 69 responses from 65 worldwide institutions, with a mean of 18 intussusception reductions performed per year: 55/69 (80%) from 52 European institutions and 14/69 (20%) from 13 institutions outside of Europe. European centres reported using 19/52 (37%) fluoroscopy, 18/52 (35%) ultrasound, and 15/52 (28%) a mixture of both, with 30/52 (58%) offering a delayed repeat at 15 min to 24 h. Non-European centres reported using 5/13 (39%) fluoroscopy, 6/13 ultrasound (46%), and 2/13 (15%) a mixture of both, with 9/13 (69%) offering a delayed repeat attempt. Sedation or analgesia was used in 35/52 (67%) of European and 2/13 (15%) non-European institutions. CONCLUSION: There is wide variation in how image-guided intussusception reduction is performed, and in the use of sedation/anaesthesia.

BACKGROUND: Liver transplantation is the state-of-the-art curative treatment in end-stage liver disease. Imaging is a key element for successful organ-transplantation to assist surgical planning. So far, only limited data regarding the best radiological approach to prepare children for liver transplantation is available. OBJECTIVES: In an attempt to harmonize imaging surrounding pediatric liver transplantation, the European Society of Pediatric Radiology (ESPR) Abdominal Taskforce initiated a survey addressing the current status of imaging including the pre-, intra-, and postoperative phase. This paper reports the responses on preoperative imaging. MATERIAL AND METHODS: An online survey, initiated in 2021, asked European centers performing pediatric liver transplantation 48 questions about their imaging approach. In total, 26 centers were contacted and 22 institutions from 11 countries returned the survey. From 2018 to 2020, the participating centers collectively conducted 1,524 transplantations, with a median of 20 transplantations per center per annum (range, 8-60). RESULTS: Most sites (64%) consider ultrasound their preferred modality to define anatomy and to plan surgery in children before liver transplantation, and additional cross-sectional imaging is only used to answer specific questions (computed tomography [CT], 90.9%; magnetic resonance imaging [MRI], 54.5%). One-third of centers (31.8%) rely primarily on CT for pre-transplant evaluation. Imaging protocols differed substantially regarding applied CT scan ranges, number of contrast phases (range 1-4 phases), and applied MRI techniques. CONCLUSION: Diagnostic imaging is generally used in the work-up of children before liver transplantation. Substantial differences were noted regarding choice of modalities and protocols. We have identified starting points for future optimization and harmonization of the imaging approach to multicenter studies.

The diagnosis of vanishing gastroschisis is made when in the presence of a full-thickness intrauterine abdominal wall defect the eviscerated loops are incarcerated in the fascial interruption. Four types of vanishing gastroschisis are described (A-D). We report on the case of a newborn with a vanishing gastroschisis-D. Gastroschisis was diagnosed at the 19th week of gestation, confirmed at the 30th, when the herniated loops previously visible to the right of the funiculus were no longer visualized. At the 32nd week, delivery was induced. The neonate weighed 1600 g, and the abdomen was distended, free from skin defects. On surgical exploration, the jejunum was 13 cm in length, with a blind ending. The post-atretic intestine measured 22 cm. A jejunostomy and a colostomy were built. The child received total parenteral nutrition for 13 months due to short bowel syndrome and was then subjected to intestinal lengthening procedure when she was 18 months old. Vanishing gastroschisis is a rare entity with a worse prognosis of the "classic" gastroschisis.
RESUMEN
Acquired vaginal strictures are rare entities in children. As a result, they are generally difficult to manage and tend to recur despite appropriate initial therapy. This case study reports the staged management of vaginal stenosis following the insertion of a button battery. In this case, an 11-year-old girl experienced at 4 years old a battery insertion in the vaginal canal by her neighbor's son, who was 6-year-old at the time. Two weeks from insertion, the parents noted the foreign body discharge spontaneously. The girl had not complained of any symptoms at the time and had been asymptomatic for many years. In November 2020, she came to the emergency department reporting cramping abdominal pain accompanied by mucopurulent discharge. An abdominal ultrasound showed the presence of hematometrocolpos, and a vaginal stenosis dilation under general anesthesia was performed the following day. After 3 weeks, the stenosis was still present, preventing the passage of Hegar number 4. The girl was subjected to a vaginoscopic stenosis resection utilizing a monopolar hook passed through an operative channel. A Bakri catheter filled with 120 mL of water was left in place. After 10 days, the girl was discharged home with the Bakri inserted. Two weeks after discharge, she was reevaluated in the outpatient setting, where the Bakri was removed with no signs of residual stenosis. Acquired vaginal stenosis could be demanding to treat, particularly with the sole conservative approach. A first-line option can be the Hegar dilation. The endoscopic approach can be a second-line, minimally invasive treatment, but long-term outcomes are difficult to predict.
RESUMEN
Anorectal and cloacal malformations are a broad mix of congenital abnormalities related to the distal rectum and anus. Confusion exists between all the forms in this large and heterogeneous group. The spectrum includes everything from anal stenosis, ventral anus, anal atresia (with and without fistula) and the full spectrum of cloacal malformations. Imaging in these conditions is done through the whole armamentarium of radiologic modalities, with very different imaging strategies seen across the centres where these conditions are managed. In 2017, the European Society of Paediatric Radiology (ESPR) abdominal imaging task force issued recommendations on the imaging algorithm and standards for imaging anorectal malformations. This was followed by further letters and clarifications together with an active multispecialty session on the different imaging modalities for anorectal malformations at the 2018 ESPR meeting in Berlin. Through this paper, the abdominal task force updates its guidelines and recommended imaging algorithm for anorectal malformations.

Since Francis Fontan first introduced the eponymous technique, the Fontan procedure, this type of surgical palliation has allowed thousands of children affected by specific heart malformations to reach adulthood. Nevertheless, abdominal, thoracic, lymphatic and neurologic complications are the price that is paid by these patients. Our review focuses on Fontan-associated liver disease; the purpose is to summarize the current understanding of its physiopathology, the aim of follow-up and the specific radiologic follow-up performed in Europe. Finally, we as members of the Abdominal Task Force of the European Society of Paediatric Radiology propose a consensus-based imaging follow-up algorithm.

Fontan surgery is a life-saving procedure for newborns with complex cardiac malformations, but it originates complications in different organs. The liver is also affected, with development of fibrosis and sometimes cirrhosis and hepatocellular carcinoma. There is no general agreement on how to follow-up these children for the development of liver disease. To understand the current practice on liver follow-up, we invited members of the European Society of Paediatric Radiology (ESPR) to fill out an online questionnaire. The survey comprised seven questions about when and how liver follow-up is performed on Fontan patients. While we found some agreement on the use of US as screening tool, and of MRI for nodule characterization, the discrepancies on timing and the lack of a shared protocol make it currently impossible to compare data among centers.

We describe an ex-premature infant presenting with severe acute respiratory syndrome coronavirus 2 infection in the fifth week of life. In current reports, researchers indicate that acute symptomatic severe acute respiratory syndrome coronavirus 2 infection is relatively rare and much less severe than in adults. This case highlights that infection can be associated with life-threatening pulmonary disease in young infants and that infection can follow a similar disease course to that described in adults. We provide first data on the use of the novel antiviral remdesivir in a young child and an innovative approach to expedited approval from a multidisciplinary clinical team and bioethics committee for compassionate access to the drug.

Gaucher disease (GD) represents the most common lysosomal storage defect. It is classified into three phenotypes: type 1 non-neuronopathic, type 2 acute neuronopathic, and type 3 subacute/chronic neuronopathic. Although children affected by GD may present with a broad spectrum of neurological signs, brain magnetic resonance imaging (MRI) findings are usually normal or non-specific. We report three cases of GD with previously undescribed brain MRI changes mainly affecting the thalami and/or the dentate nuclei. We discuss the possible etiopathogenesis of these abnormalities. Correlation between brain MRI abnormalities, neurological symptoms, and treatment efficacy is still unclear.

Hereditary ataxias are a heterogeneous group of neurodegenerative disorders, characterized by cerebellar ataxia as the main clinical feature, and a large spectrum of neurological-associated symptoms and possible multi-organ affection. Image-based approaches to hereditary ataxias in childhood have already been proposed. The aim of this review is to yield the main reports of neuroimaging patterns and diagnostic algorithms and compare them with the results from our study of 23 young patients addressed for ataxia, with subsequent genetic or metabolic diagnosis.
