Variability in perioperative evaluation and resource utilization in pediatric patients with suspected biliary dyskinesia: A multi-institutional retrospective cohort study

Document Type



Paediatric Surgery


Introduction: Biliary dyskinesia (BD) is a common indication for pediatric cholecystectomy. While diagnosis is primarily based on diminished gallbladder ejection fraction (GB-EF), work-up and management in pediatrics is controversial.
Methods: We conducted a multi-institutional retrospective review of children undergoing cholecystectomy for BD to compare perioperative work-up and outcomes.
Results: Six hundred seventy-eight patients across 16 institutions were included. There was no significant difference in gender, age, or BMI between institutions. Most patients were white (86.3%), non-Hispanic (79.9%), and had private insurance (55.2%). Gallbladder ejection fraction (EF) was reported in 84.5% of patients, and 44.8% had an EF Conclusion: There is significant variability in evaluation and follow-up both before and after cholecystectomy for BD. Prospective research with standardized data collection and follow-up is needed to develop and validate optimal care pathways for pediatric patients with suspected BD.
Study type: Case Series, Retrospective Review.
Level of evidence: Level IV.
