Abstract
BACKGROUND
This is the first case-control study investigating an association between gallbladder hyperkinesia and symptomatic acalculous chronic cholecystitis.
METHODS
This retrospective study in a single academic center compared resolution of biliary pain in adults with gallbladder hyperkinesia, defined as a hepatobiliary iminodiacetic acid scan ejection fraction ≥80%, undergoing cholecystectomy (study group) with those treated medically without cholecystectomy (control group). Of 1,477 hepatobiliary iminodiacetic acid scans done between 2013 and 2018, a total of 296 adults without gallstones had an ejection fraction ≥80%, of whom 46 patients met predetermined eligibility criteria. Demographic data, hepatobiliary iminodiacetic acid scan ejection fraction, chronicity of pain, and resolution of pain were compared between groups.
RESULTS
Demographics (mean ± standard deviation) in the control group (n = 25) and in the study group (n = 21) were, respectively, age 40 y ± 16 y and 39 y ± 14 y, body mass index 28.9 ± 5.2 and 29.1 ± 7.1 kg/m2, with 15 (60%) and 18 (86%) females in each. Resolution of pain after cholecystectomy occurred in 18 of 21 patients (86%); however, pain persisted in 20 of 25 patients (80%) treated medically after mean follow-up of 36 ± 28 months (range 10-120 months) (P < .01). Pain resolution with cholecystectomy was independent of demographic variables, hepatobiliary iminodiacetic acid scan ejection fraction, and chronicity of pain. The odds of pain resolution was 19.7 times greater with cholecystectomy than without (odds ratio, 19.7; 95% confidence interval, 4.34, 89.43; P < .01), and remained robust even with the odds adjusted for each covariate. Gallbladder histopathology confirmed chronic cholecystitis in all 21 cholecystectomy specimens.
CONCLUSION
Symptomatic gallbladder hyperkinesia could be a new indication for cholecystectomy in adults.
