Abstract BACKGROUND: Despite the increasing use of fatty meal (FM) as a substitute for cholecystokinin (CCK) in pain reproduction during hepato-imino-diacetic acid (HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application.
METHODS: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups - those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results.
RESULTS: Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction (61% vs 30%, P<0.01).
CONCLUSIONS: Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder.
