title: EUS in pediatric patients.
abstract: BACKGROUND
  The knowledge of EUS use in children is limited.
  
  
  OBJECTIVE
  We investigated the indications, feasibility, safety, and clinical utility of EUS in the management of pediatric GI, pancreatobiliary, and mediastinal diseases.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Two tertiary referral university hospitals.
  
  
  METHODS
  Consecutive children age younger than 18 years referred over a 7-year period for EUS evaluation.
  
  
  RESULTS
  Forty EUS scans were performed in 38 children with a mean age of 13.5 years. The indications for pancreatobiliary endosonography were pancreatitis (n = 10), solid pancreatic mass (n = 7), cystic pancreatic mass (n = 1), cyst in the setting of chronic pancreatitis (n = 1), suspected annular pancreas (n = 1), celiac plexus block (n = 1), suspected common bile duct stone (n = 1), abdominal pain and atrophic pancreas (n = 1), ampullary adenoma (n = 1), and abnormal MRCP in a patient with jaundice (n = 1). The indications for gastric EUS were mucosal lesions (n = 2) and subepithelial lesions (n = 4). The indications for mediastinal endosonography were mediastinal masses/lymph nodes (n = 5). The remaining evaluations were performed for esophageal stricture (n = 1), unexplained abdominal pain (n = 1), unexplained abdominal pain with celiac axis block (n = 1), and perirectal fluid collection (n = 1). EUS-guided FNA (EUS-FNA) was performed in 12 (30%) cases and established the correct diagnosis in 9 (75%). EUS-guided fine-needle injections for celiac axis block were performed in 2 (5%) cases. The procedure was successful in all patients, and no complications related to sedation, EUS, or EUS-FNA were encountered.
  
  
  CONCLUSIONS
  Retrospective study.
  
  
  CONCLUSIONS
  EUS and EUS-FNA are feasible and safe and have a significant impact on the management of pediatric GI, pancreatobiliary, and mediastinal diseases.
