Hypokinetic Biliary Dyskinesia in a Pediatric Patient: A Case Report

The diagnosis of biliary dyskinesia (BD) in pediatric patients lacks uniformity across the literature. BD is among the most common reasons for cholecystectomy in pediatric patients. Even still, diagnostic criteria for this disorder, including symptomatology and gallbladder ejection fraction, as well as the symptomatic relief after cholecystectomy, are inconsistent across the literature for the pediatric population. We share the case of an 18-year-old female patient who presented to our clinic for cholecystectomy for a diagnosis of BD. After 10 months of seeking a diagnosis, an eventual nuclear medicine HIDA scan revealed a biliary ejection fraction of 18%, leading her to our care. The patient underwent robotic-assisted laparoscopic cholecystectomy and tolerated the procedure well, reporting a resolution of symptoms on follow-up. The diagnosis and management of BD are complicated by the combination of vague and varied symptomatology and a lack of definitive, uniform diagnostic criteria in the pediatric population. Variability in diagnostic requirements varies between sources. While some look to the interpretation of gallbladder emptying studies, others rely on surgical outcomes. To further complicate diagnosis, some patients experience symptoms that do not correlate with their gallbladder emptying studies. The controversy extends beyond diagnosis as some studies argue against cholecystectomy as a treatment for BD, as it has been shown to not always resolve symptoms. More research should be conducted to identify and establish more consistent diagnostic criteria for BD in the pediatric population, as well as to study symptomatic improvement following cholecystectomy to establish optimal treatment for these patients. Biliary dyskinesia is a relatively common but rather inconsistent diagnosis in the pediatric population, and attention should be turned toward developing uniform and consistent diagnostic criteria in order to optimally recognize, diagnose, and treat these patients, ensuring a shorter time-to-diagnosis and improved quality of life.
