Biliary dyskinesia is a potential cause for acalculous biliary colic in pediatric patients. A triad of symptoms and signs, consisting of abdominal pain (with or without associated nausea or fatty food intolerance), absence of gallstones, and an abnormally low cholecystokinin-stimulated gallbladder ejection fraction is used to diagnose the disorder. In several small pediatric case series, cholecystectomy resulted in symptomatic improvement in a majority of patients with biliary dyskinesia. However, the diagnosis of biliary dyskinesia and appropriate management remain controversial. This review discusses the purported pathophysiology of biliary dyskinesia and the data available regarding diagnosis and treatment of this entity in the pediatric population.

Biliary dyskinesia (BD) is a motility disorder of the gallbladder that can result in right upper quadrant (RUQ) pain, nausea, vomiting, and diarrhea. Cholecystectomy is considered the standard of care for BD. Up to 23 per cent of pediatric patients who undergo surgery for BD have persistent symptoms postoperatively. We performed a retrospective review to identify preoperative factors significantly associated with symptom resolution after cholecystectomy. We retrospectively reviewed pediatric patients aged 10-17 years diagnosed with BD who underwent cholecystectomy between 2006 and 2016. Patients were divided into two groups based on postoperative symptom resolution. Chi-squared and student t tests were used to compare patient groups. Two hundred and thirty-six patients were included in the study. The most common preoperative symptoms included RUQ pain (80.1%), nausea (54.2%), postprandial pain (44.5%), vomiting (32.6%), and epigastric pain (19.9%). The rate of postoperative symptom resolution was 68.6 per cent. Comparative analysis showed patients who presented with RUQ pain, nausea, postprandial pain, or constipation experienced significantly higher rates of symptom resolution postoperatively. In addition, patients with ejection fraction <35 per cent or pain reproducible with cholecystokinin were found to have significantly higher rates of symptom resolution as well. To date, it remains difficult to predict successful outcomes for pediatric patients undergoing cholecystectomy for BD. In our study, patient demographics and duration of symptoms did not affect postoperative outcomes. Pediatric patients who presented with RUQ pain, nausea, postprandial pain, constipation, an ejection fraction of <35 per cent on hepatobiliary iminodiacetic acid, or pain reproducible with cholecystokinin injection, were found to have significantly higher rates of symptom resolution.
