Hida scan showing ef rate of 90%. is it too high? will they take my gb out? had ruq pain and ct/us/endoscopy/blood test negative for anything

Normal gallbladder: Hida scans measure several things--uptake & excretion of hida by liver, gallbladder function, ductal patency/ function. Cck is given to stimulate gallbladder contraction--mimicking food entering the duodenum from stomach. If the gallbladder has a sluggish ejection fraction (ef<35%) then the gallbladder is sick & surgical removal is recommended. When ef=90% (is normal) surgery is not warranted.

Probably not.: Hyperkinetic or hyperactive gallbladder is not generally accepted as a diagnosis. A small group of patients (63) was symptomatic with cck infusion with greater than 80% ejection fraction. 28 of these patients underwent removal of gall bladder. 97% of these 28 patients showed improvement in symptoms following surgery. More prospective and retrospective studies needed.To substantiate the findings.
