Risk scores for choledocholithiasis perform poorly in patients with hemolytic diseases: a PEDI database report

Area of Science:

• Pediatric Gastroenterology
• Hepatobiliary Diseases
• Endoscopic Procedures

Background:

• Patients with hemolytic diseases face higher risks of gallstone complications.
• Existing scoring systems aim to identify pediatric patients who may benefit from ERCP for choledocholithiasis.

Purpose of the Study:

• To assess the effectiveness of current criteria in identifying pediatric patients with hemolytic diseases who would benefit from ERCP.
• To evaluate the performance of established selection criteria in this specific patient group.

Main Methods:

• Secondary analysis of prospectively collected data from the Pediatric ERCP Database Initiative (1,124 ERCPs).
• Comparison of patients with and without hemolytic diseases regarding ERCP outcomes and adherence to selection criteria.
• Statistical analysis using two-tailed Fisher's exact test and paired Student's t-test.

Main Results:

• Of 47 pediatric patients with hemolytic diseases, 72.3% had common bile duct (CBD) stones at ERCP.
• No significant differences in pre-ERCP findings between patients with and without CBD stones.
• Existing criteria (ASGE high-risk, modified Baylor) poorly predicted choledocholithiasis in this cohort, with 80-90% of patients without stones meeting high-risk criteria.
• A trend towards increased adverse events was observed in patients with hemolytic diseases.

Conclusions:

• Current ERCP selection criteria are inadequate for pediatric patients with hemolytic diseases, leading to overestimation of choledocholithiasis risk.
• Underutilization of advanced imaging modalities like endoscopic ultrasound and MRCP may necessitate their increased use in this population.
• Revised or alternative strategies are needed for accurate patient selection for ERCP in pediatric hemolytic disease cases.
