Biliary dyskinesia is defined as symptomatic biliary colic without cholelithiasis, and is diagnosed during cholescintigraphy by assessing gallbladder emptying with cholecystokinin (CCK) stimulation. Unfortunately, gallbladder emptying is not routinely assessed during cholescintigraphy in pediatric patients. The purpose of this review is to assess the effectiveness of cholecystectomy in patients with chronic abdominal pain and delayed gallbladder emptying and to assess whether these findings correlate with the histologic evidence of chronic cholecystitis. We retrospectively reviewed the medical records of all patients ( n=16) at our institution from October 1997 to August 2001 who underwent quantitative cholescintigraphy with CCK stimulation that demonstrated delayed gallbladder emptying (< 35% at 60 min) and who subsequently underwent cholecystectomy. Laparoscopic cholecystectomy was performed in 16 patients with chronic abdominal pain. All 16 patients had delayed gallbladder emptying (mean ejection fraction: 15+/-8%, range: 3-32%). The mean age was 12+/-2 years (range: 8-17 years). Presenting symptoms included abdominal pain (86%), fatty food intolerance (27%), emesis (13%), and diarrhea (13%). Mean duration of abdominal pain before operation was 11+/-19 months (range: 2 weeks-6 years). One patient's symptoms persisted postoperatively, but abdominal pain resolved in all other patients. Histologic evidence of chronic cholecystitis was demonstrated in 86% of surgical specimens. Five patients underwent concurrent appendectomy, and all had normal appendiceal histology. Our experience suggests that children with chronic abdominal pain and delayed gallbladder emptying on CCK-stimulated cholescintigraphy are likely to benefit from cholecystectomy and to have histologic evidence of chronic cholecystitis.

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.
