Influence of Stone Size on Spontaneous Migration of Choledocholithiasis in Pediatric Patients

jpedsurg.org

The incidence of choledocholithiasis in pediatric patients with gallstones is higher than in adults (30%). However, spontaneous migration is very common in these patients. To date, no pediatric studies have analyzed the relationship between stone size in the common bile duct (CBD) and spontaneous migration.

In brief

This study examines the relationship between common bile duct stone size and spontaneous migration rates in pediatric choledocholithiasis patients. Unlike adults, children experience higher rates of CBD stones (30%) but also more frequent spontaneous passage, yet stone size predictors remain unstudied in this population.

Choledocholithiasis occurs in 30% of pediatric gallstone cases—higher than adult incidence.
Spontaneous stone migration from the CBD is very common in pediatric patients.
No existing pediatric studies correlate CBD stone size with spontaneous migration rates.
Pediatric choledocholithiasis may have different natural history than adult disease.
Understanding stone size thresholds could guide conservative vs. interventional management.
