Background and Objectives: The safety and utility of endoscopic ultrasound (EUS) for the evaluation and management of gastrointestinal (GI) tract disorders among adults has been established. The literature on safety and efficacy in a pediatric referral population (under 21 years of age) is limited. We hypothesized that EUS is safe and useful in the pediatric population. We reviewed the pediatric EUS experience at a single tertiary-care system. We describe the indications, findings, safety, technical success rate, and impact on clinical outcomes. Patients and Methods: All patients 21 years of age or younger referred for EUS between 5, 2007 and 11, 2012 were identified from our electronic medical record databases. Retrospective chart review was then conducted to document demographics, procedure indications, procedure type (diagnostic or therapeutic), type of anesthesia used, EUS findings, and the clinical impact of EUS on the subsequent management of the patients. Results: Seventy EUS procedures were attempted in 58 patients during the study. Of these, two EUS procedures were aborted due to inadequate moderate sedation and 68 were successfully completed. The median age at initial endoscopy was 18 years (range 6-21 years), 50% were male and 65% were Caucasian. Four patients underwent EUS-guided pseudocyst drainage. Among the remaining 54 patients, the indications for EUS were the evaluation of GI mucosal/submucosal lesions (n = 14), acute or recurrent pancreatitis (n = 10), localization of suspected insulinoma (n = 8), evaluation of pancreatic abnormalities seen on prior imaging (n = 6), surveillance of tumors or evaluation of luminal lesions in hereditary syndromes (n = 6), abdominal pain of suspected pancreatobiliary origin (n = 5), and other rare indications (n = 5). Fine-needle aspiration was performed in 13 (9 diagnostic, 4 therapeutic) and trans-gastric fine-needle contrast injection of the pancreatic duct was performed in one patient without any complications. Sedation (data available for 66 procedures) included general endotracheal anesthesia in 38 (57%), monitored anesthesia care (MAC) in 19 (29%), and moderate sedation in 9 (14%). There were 4 minor intra-procedural anesthesia-related complications (laryngospasm in 2 and hypoxemia from airway obstruction and secretions in 2) in MAC and general endotracheal anesthesia (GA) cases, and 1 postprocedural complication (fever after pseudocyst drainage). EUS can achieve the diagnostic or therapeutic goal and ruled out suspected pathology in 88% of cases precluding need for additional testing. Conclusions: (1) EUS in the pediatric population is technically successful and efficacious. (2) Therapeutic and diagnostic EUS impacted clinical care decisions. (3) There is a low risk of immediate significant complications. (4) The overall efficacy and safety support the performance of EUS in a pediatric population by experienced endoscopists.
