Objective: Classic biliary colic and a cholecystokinin hepatobiliary iminodiacetic acid (CCK-HIDA) scan demonstrating an ejection fraction less than 35% is a well-established indication for cholecystectomy as definitive treatment. However, in patients without stones and symptoms consistent with biliary colic, an ejection fraction >80% is not widely accepted as an indication for cholecystectomy. The objective of our study was to evaluate hyperkinetic biliary dyskinesia (defined as a gallbladder ejection fraction of greater than or equal to 80%) as a predictor of symptom resolution following cholecystectomy.
Methods: All patients undergoing cholecystectomy from 2010 to 2016 at a single institution were reviewed. Patients with an ICD-9 code for cholelithiasis or acute cholecystitis were excluded from the study. A retrospective chart review of the remaining patients was performed. Patients with symptoms consistent with biliary colic (postprandial right upper quadrant pain with or without nausea), a right upper quadrant ultrasound negative for gallstones, and a CCK-HIDA scan with documented ejection fractions greater than or equal to 80 percent were included. A total of 403 patient charts were reviewed, 31 met study criteria and 23 had clearly documented follow up. Improved or resolved preoperative pain, determined from patient’s post-operative clinic visit documentation was the primary endpoint. Surgical pathology was reviewed for evidence of pathologic changes and to confirm the absence of stones.
Results: Of the 23 patients included in the study, 21 patients (91.3%) reported improvement or complete resolution of their preoperative pain. Nineteen (90.5%) of the 21 patients with symptom improvement or resolution had pathologic findings of chronic cholecystitis. Only 2 patients (8.7%) reported no change in preoperative symptoms.
Conclusions: Patients with symptomatic hyperkinetic biliary dyskinesia, as defined by an ejection fraction greater than or equal to 80% on CCK-HIDA may benefit from cholecystectomy. Additionally, 90.5% of patients with improvement or resolution were found to have pathology consistent with chronic cholecystitis providing support of an underlying pathology contributing to symptoms of biliary colic.
