Background and Aims: Ionizing radiation exposure during endoscopic retrograde cholangiopancreatography (ERCP) is an important quality issue especially in children. We aim to identify factors associated with extended fluoroscopy time (FT) in children undergoing ERCP. Methods: ERCP on children Results: 1073 ERCPs performed in 816 unique patients met inclusion criteria. Median age was 12.2 years (interquartile range [IQR] 9.3-15.8). 767 (71%) patients had native papillae. The median FT was 120 seconds (IQR 60-240). Factors associated with increased FT included procedures performed on patients with chronic pancreatitis, ERCPs with American Society of Gastrointestinal Endoscopy (ASGE) difficulty grade >3, ERCPs performed by pediatric gastroenterologist (GI) with adult GI supervision, and ERCPs performed at non-free standing children's hospitals. Hispanic ethnicity was the only factor associated with lower FT. Conclusion: Several factors were associated with prolonged FTs in pediatric ERCP that differed from adult studies. This underscores that adult quality indicators cannot always be translated to pediatric patients. This data can better identify children with higher risk for radiation exposure and improve quality outcomes during pediatric ERCP.
