  • Title: Fluoroscopy Time During Endoscopic Retrograde Cholangiopancreatography Performed for Children and Adolescents is Significantly Higher With Low-volume Endoscopists.

    Abstract:
    BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is a fluoroscopy and endoscopy-based procedure important for diagnosis and management of pediatric pancreaticobiliary disorders. Patient, procedure, endoscopist, and facility characteristics have been shown to influence ERCP complexity and procedure outcomes as well as fluoroscopy utilization in adults; however, the extent to which this is true in pediatric patients remains under-studied and there are minimal data regarding fluoroscopy utilization in pediatric ERCP. METHODS: We retrospectively analyzed ERCPs performed on patients <18 years of age at our tertiary care children's hospital from 2002 to 2017 using our institution's paper and electronic medical record system along with a prospectively maintained radiation exposure database. Procedure complexity was graded using the Stanford Fluoroscopy Complexity Score and the American Society of Gastrointestinal Endoscopy Complexity scale. High-volume endoscopists (HVE) were defined as having a cumulative annual ERCP volume >100 and low-volume endoscopists (LVE) as <100 (pediatric + adult) ERCPs/year. RESULTS: Three hundred eighty-five ERCPs performed on 321 patients were included in this analysis. The mean patient age was 13.4 years (+/- 4.2 years), 77% were index ERCPs (native ampullas), and 81% were performed with therapeutic intent (87% for biliary indication and 13% for pancreatic indication). Fluoroscopy times (FTs) varied between procedures and providers. Median FT was 4.85 (+/- 2.68) minutes. Endoscopist annual ERCP volume was the strongest predictor of FT (P < 0.001). In addition to endoscopist volume, procedure-specific predictors of increased FT included pancreatic indication for the procedure, biliary or pancreatic duct stricture, patient age <4 years or >16 years at the time of ERCP (P < 0.01 for each), and native ampulla. ERCP complexity rating based on the Stanford Fluoroscopy Complexity Score correlated with FT. CONCLUSIONS: Radiation exposure is higher than desirable for pediatric ERCP and varies with endoscopist as well as patient and procedure-specific factors. HVE perform ERCP with lower FT relative to LVE even though HVE procedure complexity was higher. The Stanford Fluoroscopy Score predicted FT for pediatric ERCP, but the ASGE ERCP complexity scale did not. Adaptation and refinement of pediatric-specific ERCP complexity scales including factors, such as patient size and age and indications/interventions more consistent with those encountered in pediatrics could be beneficial.
