Chronic acalculous cholecystits typically presents with biliary symptoms, normal blood tests and unremarkable ultrasound, computerized tomography and magnetic resonance cholangiopancreatography. However, cholescintigraphy may show reduced gallbladder ejection fraction (GBEF). There are no reports on using ultrasound to measure GBEF in adults. Twenty-eight @entity1 with the above presentation underwent ultrasound before and after ingestion of a standardized fatty meal. Consequently, GBEF was calculated. Seven @entity1 had reduced GBEFs (<38%). Two of these @entity1 underwent cholecystectomy and both were found to have chronic @entity2679 . Three @entity1 with normal GBEFs underwent cholecystectomy and were also found to have chronic @entity2679 . There may be a role for fatty meal ultrasonography in the diagnosis of chronic @entity7140 , but it should be used more widely in this @entity1 cohort for its role to be established. It ideally needs to performed alongside cholescintigraphy for the comparison of accuracy.
