Role of endoscopic ultrasound in pediatric patients: A single tertiary center experience and review of the literature

Abstract
BACKGROUND Although endoscopic ultrasound (EUS) is now widely available and has an established role in adults, the utility of EUS and EUS-guided fine needle aspiration (EUS-FNA) in pediatrics is insufficiently described compared to adults and is supported by only a few studies. AIM To report the experience of a single tertiary center in the use of EUS and EUS-FNA in a pediatric population and to further assess its safety, feasibility, and clinical impact on management. METHODS A retrospective study of 13 children (aged 18 years or younger) identified from our medical database was conducted. A retrospective review of demographic data, procedure indications, EUS findings, and the clinical impact of EUS on the subsequent management of these patients was performed. RESULTS During the 4-year study period, a total of 13 (1.7%) pediatric EUS examinations out of 749 EUS procedures were performed in our unit. The mean age of these 8 females and 5 males was 15.6 years (range: 6-18). Six of the 13 EUS examinations were pancreatobiliary (46.1%), followed by mediastinal 2/13 (15.4%), peri-gastric 2/13 (15.4%), abdominal lymphadenopathy 1/13 (7.7%), tracheal 1/13 (7.7%) and rectal 1/13 (7.7%). Overall, EUS-FNA was performed in 7 patients (53.8%) with a diagnostic yield of 100%. The EUS results had a significant impact on clinical care in 10/13 (77%) cases. No complications occurred in these patients during or after any of the procedures. CONCLUSION EUS and EUS-FNA in the pediatric population are safe, feasible, and have a significant clinical impact on the subsequent management; thus avoiding invasive and unnecessary procedures.
