Abstract
BACKGROUND: This study aimed to aid in risk assessment of pediatric endoscopic retrograde cholangiopancreatography (ERCP) candidates by utilizing a national pediatric database with a large sample to assess how patient characteristics may affect ERCP complication rates. METHODS: The Kids' Inpatient Database (KID) is a sample of pediatric discharges in states participating in the Healthcare Cost and Utilization Project (HCUP). This database provides demographic information, hospitalization duration, and outcome information for hospitalizations during which an ERCP occurred. International Classification of Diseases (ICD) codes were used to determine the hospitalization indication. ERCP complication rate was ascertained via ICD codes. All statistical analyses were performed using SAS 9.4. RESULTS: Complications were seen in 5.4% of hospitalizations with mortality observed in less than 0.2%. This analysis captured a large Hispanic population, specifically in the South and West regions. Gallbladder calculus and cholecystitis were more likely to occur in females. A higher percentage of patients in the age 10 - 17 group were female (72.2% vs. 52.7%, P < 0.01) and Hispanic (33.4% vs. 22.7%, P < 0.01) compared to the age 0 - 9 group. Age 0 - 5 and male gender were associated with lower routine home discharge rates and longer lengths of stay. Complications occurred at a higher rate in ages 0 - 5, though the difference was not statistically significant. CONCLUSIONS: ERCP is a safe procedure for pediatric patients with low complication rates and rare mortality. We found statistically significant differences in the procedure indications between pediatric age groups, races, and genders. Age ≤ 5 years and male gender were associated with more complicated healthcare courses.
