In brief
Retrospective study establishes age-stratified normal common bile duct diameter ranges in 778 pediatric patients using ultrasound, with validation against choledocholithiasis cases. Findings provide diagnostic reference standards to improve accuracy in detecting CBD obstruction in children under 21 years.
Written by the GCMD Library team from the article.
Background/Purpose
The incidence of choledocholithiasis is increasing. The diagnosis of common bile duct (CBD) obstruction is based on abnormal CBD size. Establishing norms for CBD size in children would improve diagnostic accuracy. We analyzed ultrasounds (US) to determine normal pediatric CBD size based on age and then validated this against patients with choledocholithiasis.
Methods
A retrospective review was conducted for children less than 21 years of age with US defined CBD size. Patients were stratified into age groups by ANOVA statistical analysis. Secondary analysis included patients with confirmed choledocholithiasis in comparison to the normal cohort.
Results
A total of 778 patients had US without pathology. Group 1 (10 years) 2.98±1.17 mm, p
