Abstract:
Esophagogastroduodenoscopy (EGD) is a frequently utilized investigative tool in the management of gastrointestinal conditions in children. Biopsies obtained during EGD may pose risk for post-operative adverse events (AEs), and further understanding of risk is imperative to provide informed consent to families and safe patient care. In particular, the impact of biopsy number and location on the development of AEs has not been studied in pediatric patients. We prospectively assessed for AEs by telephone survey 3-7 days after 209 EGDs performed on patients ages 1-21 years over a 1-year period. Demographic, endoscopic, and histologic data were collected. The most common symptoms reported were throat pain (61%), chest pain (26%), and dysphagia (26%). Binary regression models identified age and pre-operative symptoms as factors that influenced the likelihood of post-operative morbidity. Multiple biopsies from 3 different locations of the esophagus did not impact the risk of post-operative AEs.
