Oesophageal wall thickness assessment at endoscopic ultrasound in children and adolescents with eosinophilic oesophagitis: a case-control study.

Purpose: Eosinophilic oesophagitis (EoE) is a chronic immune-mediated disease, and an endosonographic evaluation may help the diagnosis. The main objectives of this study were to measure the thickness of the oesophageal wall using a radial endoscopic ultrasound (EUS), mucosa/submucosa (MSM), muscularis propria (MP) and mucosa to muscularis propria (MMP); to compare these measurements between patients with and without EoE; to correlate them with the Endoscopic Reference Score (EREFS); and to evaluate the diagnostic accuracy of these measurements.

Methods: Children and adolescents (aging from 4 to 17 years) were evaluated in this prospective cross-sectional study.

Efficacy and safety of endoscopic ultrasound-guided drainage of pancreatic pseudocysts using double-pigtail plastic stents: A single tertiary center experience.

Objectives: Pancreatic pseudocysts (PPC) are fluid collections with a well-defined wall that persist for more than 4 weeks inside or around the pancreas as a result of pancreatic inflammation and/or a ductal lesion. PPC have been successfully treated with endoscopic ultrasound (EUS)-guided drainage using different stents. This study aimed to evaluate the safety and efficacy of EUS-guided drainage of PPC using double-pigtail plastic stents in a tertiary hospital.

Gastroesophageal reflux in cystic fibrosis across the age spectrum.

Background: Scientific advances have improved longevity in cystic fibrosis (CF) patients and many of these patients can expect to experience age-related gastrointestinal co-morbidities. We aimed to assess the extent to which age might impact gastroesophageal reflux (GER) in patients with CF.

Methods: Our esophageal pH-multichannel intraluminal impedance monitoring database was searched for tracings belonging to CF patients ≥2 years old without prior fundoplication and not taking anti-reflux medications immediately prior (within 7 days) and during the study.

Not All Children with Cystic Fibrosis Have Abnormal Esophageal Neutralization during Chemical Clearance of Acid Reflux.

Purpose: Acid neutralization during chemical clearance is significantly prolonged in children with cystic fibrosis, compared to symptomatic children without cystic fibrosis. The absence of available reference values impeded identification of abnormal findings within individual patients with and without cystic fibrosis. The present study aimed to test the hypothesis that significantly more children with cystic fibrosis have acid neutralization durations during chemical clearance that fall outside the physiological range.
