endoscopic ultrasound in children

OBJECTIVES: Prenatally diagnosed complex arachnoid cysts are very rare. While the true prenatal incidence is still unknown, they account for approximately 1% of intracranial masses in newborns. They rarely exhibit rapid growth or cause obstructive hydrocephalus, but if they increase to such a dimension during pregnancy, the ideal management is not well established. We present our detailed perinatal experience, covering prenatal diagnosis, a compassionate delivery process, and neonatal stabilization...

BACKGROUND: Isolated gastrocnemius contracture has been associated with more than 30 lower limb disorders, including plantar heel pain/plantar fasciitis, Achilles tendinosis, equinus foot, adult flatfoot, and metatarsalgia. Although many techniques are available for gastrocnemius recession, potential anesthetic, cosmetic, and wound-related complications can lead to patient dissatisfaction. Open and endoscopic recession techniques usually require epidural or general anesthesia, exsanguination of the lower extremities and stitches and can damage the sural nerve, which is not under the complete control of the surgeon at all stages of the procedure...

PURPOSE: To summarize our experience in the management of congenital anomalies in the kidney and urinary tract (CAKUT) in adults. MATERIALS AND METHODS: We conducted a retrospective chart review of all adult patients who underwent primary surgical intervention for CAKUT between 1998 and 2021. RESULTS: The study included 102 patients with a median age of 25 (interquartile range, 23-36.5). Of these, 85 (83.3%) patients reported normal prenatal ultrasound, and the remaining 17 (16...

BACKGROUND: Neuroendocrine tumors (NETs) are rare epithelial neoplasms that arise most commonly from the gastrointestinal tract. In pediatrics, the most common site of origin is in the appendix, with the liver being the most common site of metastasis. Neuroendocrine tumors arising from the biliary tract are extremely rare. METHODS: We describe a case of a nine-year-old girl who presented with obstructive cholestasis and was found to have multiple liver masses identified on biopsy as well-differentiated neuroendocrine tumor with an unknown primary tumor site...

Inflammatory bowel disease (IBD) comprises a group of relapsing, chronic diseases of the gastrointestinal tract that, in addition to adults, can affect children and adolescents. To detect relapses of inflammation, these patients require close observation, frequent follow-up, and therapeutic adjustments. While reference standard diagnostics include anamnestic factors, laboratory and stool sample assessment, performing specific imaging in children and adolescents is much more challenging than in adults. Endoscopic and classic cross-sectional imaging modalities may be invasive and often require sedation for younger patients...

BACKGROUND: Endoscopic ultrasound-guided fine needle aspiration biopsy (EUS FNAB) is a well established diagnostic method in adult patients, but is rarely used in the paediatric population. The Clinical Department of Gastroenterology at the University Clinical Centre Ljubljana and the Department of Cytopathology at the Institute of Pathology, Faculty of Medicine, University of Ljubljana, Slovenia, have been closely collaborating on EUS FNAB since the introduction in 2010. The aim of the study was to review the cases of EUS FNAB of pancreatic neoplasms in children...

BACKGROUND: Ultrasound is an integral part of evaluating for acute cholecystitis and choledocholithiasis in pediatric patients. Finding the common bile duct (CBD), a structure which is normally <4 mm in children, can be very challenging. OBJECTIVE: The primary objective of this study was to determine the prevalence of isolated sonographic CBD dilation in pediatric patients with acute cholecystitis and/or choledocholithiasis without laboratory abnormalities or pathologic findings on radiology based biliary ultrasound, apart from cholelithiasis...

BACKGROUND: Foreign bodies in the pediatric urogenital tract are rare but urgent clinical conditions that can cause severe symptoms and complications. The current management remains challenging. OBJECTIVE: This study aims to provide an in-depth understanding of the clinical characteristics, diagnostic challenges, and treatment strategies for pediatric urogenital tract foreign bodies. Through a retrospective analysis of patient data, valuable insights into the management of this condition are offered to facilitate the development of more effective management strategies...

OBJECTIVE: Neuronavigation is a useful adjunct for catheter placement during neurosurgical procedures for hydrocephalus or ventricular access. MRI protocols for navigation are lengthy and require sedation for young children. CT involves ionizing radiation. In this study, the authors introduce the clinical application of a 1-minute rapid MRI sequence that does not require sedation in young children and report their preliminary clinical experience using this technique in their pediatric population...

Paediatric chronic pancreatitis (CP) is a rare and debilitating pathology that often requires invasive diagnostics and therapeutic interventions either to address a primary cause such as a pancreaticobiliary malunion or to deal with secondary complications such as chronic pain. Endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are two endoscopic modalities that have an established diagnostic role in paediatric CP, and their therapeutic utilisation is increasing in popularity...

OBJECTIVE: This research aims to explore the efficiency and safety of endoscopic combined intrarenal surgery (Micro-ECIRS) composed of micro-percutaneous nephrolithotomy (Micro-perc) and retrograde intrarenal surgery (RIRS) in the Galdakao-modified supine Valdivia (GMSV) position for a single session for the treatment of complex nephrolithiasis in children. MATERIALS AND METHODS: This study retrospectively reviewed patients aged < 18 years who underwent Micro-ECIRS in the GMSV position for renal stones larger than 2 cm under ultrasound guidance between August 2020 to May 2022 at our institution...

BACKGROUND AND AIMS: STRIDE-II recommends early biomarker targets for treatment optimization to achieve treat-to-target (T2T) endoscopic remission (ER) in Crohn's disease (CD). Predictive capabilities of intestinal ultrasound (IUS) for T2T ER remains unknown. We aimed to evaluate IUS response to predict ER in children with CD. METHODS: Prospective longitudinal cohort study of children with ileal (TI) CD initiating biologic therapy undergoing IUS, clinical disease activity, and C-reactive protein (CRP) assessments at baseline, week 8, 6 months, and T2T within 1 year...

INTRODUCTION: High rates of screen failure for the minimum Simple Endoscopic Score for Crohn's Disease (SES-CD) plague Crohn's disease (CD) clinical trials. We aimed to determine the accuracy of segmental intestinal ultrasound (IUS) parameters and scores to detect segmental SES-CD activity. METHODS: A single-center, blinded, cross-sectional cohort study of children and young adult patients with CD undergoing IUS and ileocolonoscopy, comparing segmental IUS bowel wall thickness (BWT), hyperemia (modified Limberg score [MLS]), and scores to detect segmental SES-CD activity: (i) SES-CD ≤2, (ii) SES-CD ≥6, and (iii) SES-CD ≥4 in the terminal ileum (TI) only...

Acute appendicitis is one of the common acute abdominal diseases in pediatrics. However, the implementation of radiological examination guided endoscopic retrograde appendicitis therapy (ERAT) in adults is limited in children. Our previous research explored the non-invasive guidance of high-frequency ultrasound (HFUS) for ERAT and achieved good therapeutic effects. This study mainly focuses on exploring the application value of HFUS in the feasibility assessment of ERAT in children with appendicitis. 163 children with appendicitis received ERAT guided by HFUS were analyzed retrospectively...

BACKGROUND AND AIMS: Objective evaluation of treatment response is critical in the management of Crohn's disease (CD). Compared with endoscopy, intestinal ultrasound (IUS) is non-invasive and well-tolerated. This study is aimed to assess the predictive value of IUS score for treatment response in pediatric CD patients. METHODS: We conducted a retrospective study in pediatric CD patients who underwent endoscopy and IUS at start of infliximab treatment [T0] and after 22-38 weeks [T1] between February 2021 and January 2023...

BACKGROUND: Endoscopic treatment of vesicoureteral reflux (VUR) is an important minimally invasive surgical approach in patients undergoing surgical treatment of VUR. In our past experience, we observed that a bulking agent mound sagittal diameter of 10 mm is the main predictor of effectiveness of the procedure. Moreover we noticed that the use of intraoperative ultrasound, allows the surgeon to better identify the site, volume and shape of the bulking agent injected, finally reducing operative time...

INTRODUCTION: The achievement of alimentary competencies is a milestone in the development of preterm neonates. Ten percent of neonates <37 weeks of gestational age and 25% of those VLBW experience swallowing disorders, with an increased risk of problems in the early phase of life (failure to thrive, growth retardation, inhalation, and consequent risk of pulmonary infection) and later in life due to delayed development of oromotor skills.The main diagnostic tools for swallowing disorders are endoscopic (fiber-optic endoscopic examination of swallowing, FEES) or radiographic (videofluoroscopic swallowing study, VFSS) exams...

Management of the posterior urethral valve (PUV) is a clinical challenge in pediatric urology. We report the results of a modified valve ablation method without using a pediatric resectoscope and thermal energy. Patients were selected from children with PUV who were referred to the pediatric urology clinic of Shahid Labbafinejad Hospital, Tehran, Iran, and have undergone endoscopic valve ablation surgery between May 2019 to May 2021. Ten male patients with PUV underwent mechanical valve ablation without the use of the conventional pediatric resectoscope, and thermal energy was replaced by a 6F semi-rigid urethroscope and 3Fr ureteral catheter...

INTRODUCTION AND OBJECTIVE: Ureteral reimplantation of the dilated ureter in infants is challenging; however, some patients with primary obstructive megaureter (POM) in this age group require intervention due to clinical or radiological progression. We sought to determine if high pressure balloon dilation (HPBD) can serve as a definitive treatment for POM in children under one year of age, or as a temporizing measure until later reimplantation. MATERIALS AND METHODS: All patients from a single institution who underwent HPBD between October 2009 and May 2022 were retrospectively reviewed...

The need for cholecystectomy during pediatric age has significantly increased in the last two decades. As biliary pathology increases, the probability of complicated cholecystectomies increases too. The aim of this article is to analyze our experience with difficult laparoscopic pediatric cholecystectomy, focusing on the importance of an accurate pre-operative imaging study. We retrospectively analyzed all patients affected by cholelithiasis who underwent laparoscopic cholecystectomy at the Pediatric Surgery Department of San Camillo Forlanini hospital of Rome and Santa Maria alle Scotte University Hospital of Siena from 2017 to 2022...
