GBEF measures how much bile your gallbladder releases at one time. Bile helps your body digest fat. When you eat fat, your gallbladder releases bile into your bile duct. A GBEF is usually measured during a test called a hepatobiliary iminodiacetic acid (HIDA) scan. This simulates the 30-min-after-Kinevac gallbladder ejection fractions used for comparison with the normal values that clinicians use; that is, gallbladder ejection fraction is normal if it is >35%–40% at 30 min after injection of Kinevac.

Cholecystectomy may be considered for patients whose gallbladder ejection fractions were calculated to be between 35% and 60% if the patient's symptoms were classical for biliary disease and have been present for 1 year. A consistent 30 min of the ejection period is used for ejection fraction calculations instead of the variable-length ejection periods of the other methods. This simulates the 30-min-after-Kinevac gallbladder ejection fractions used for comparison with the normal values that clinicians use; that is, gallbladder ejection fraction is normal if it is >35%–40% at 30 min after injection of Kinevac. A normal ejection fraction for the gallbladder is considered between 35 to 65 percent. An ejection fraction less than 40% is abnormal. Because not all patients with suspected functional gallbladder disorder will benefit from surgery, clinical considerations and the results of the Background: Most studies recommend cholecystectomy for patients with biliary dyskinesia, defined by gallbladder ejection fraction (GBEF) of less than 35-40% on HIDA scan.

JPGN Journal of Pediatric Gastroenterology and Nutrition Publish Ahead of Print DOI : 10.1097/MPG.0000000000001065 Gallbladder Ejection Fraction is Unrelated to Gallbladder Pathology in Children and Adolescents Every department of nuclear medicine may have a different range of normal for gallbladder ejection fraction (GBEF) as determined by a HIDA scan. I have seen > 30%, > 35%, and > 40% as being considered normal, but most healthy people have GBEF > 75 %. Therefore your result is likely on the low side. This was on a medical forum and posted by a GI. Gallbladder ejection fraction (GBEF) in response to CCK injection is calculated using special computer software program. A normal gallbladder ejection fraction is equal to or greater than 35%. Alternative to CCK injection, the patient may be administered milk as a fatty drink that should stimulate a normal gallbladder to contract when it reaches the duodenum approximately 15-20 minutes after Gallbladder ejection fraction (GBEF) measured with a fatty meal (half-and-half milk) was compared with that measured with 2 equal sequential intravenous infusions of cholecystokinin (CCK-8) in a paired study of healthy subjects.

Patients who suffer from bouts of biliary pain and have lower ejection fraction readings are assumed to have ABP. Studies have shown that surgical removal of the gallbladder (cholecystectomy) helps ABP patients more than 90 percent of the time. Normal ejection fraction of a healthy gallbladder is between 35 and 75 %.

If you have no stones and no pain you might just see if your symptoms change and let that help … 2018-01-03 Cholescintigraphy is often normal in the setting of chronic cholecystitis, although delayed (>1 hour) filling of the gallbladder is seen in some patients. Patients with symptomatic chronic cholecystitis may demonstrate a low gallbladder ejection fraction. View chapter Purchase book. Our aim was to evaluate the relationship of a diminished Gallbladder Ejection Fraction (GBEF) on HIDA with gallbladder pathology in a large population of pediatric patients. Methods: The medical records of 289 children who underwent cholecystectomy from 1998 - 2005 at Kosair Children's Hospital were reviewed. 104 of these children also underwent HIDA Scan.

Probably as important is whether the injection of cck recreated the symptoms that you are having. If it does, then gallbladder is the likely cause. In gallbladder dysfunction, ultrasound examination of the gallbladder is usually normal, with no cholelithiasis, biliary sludge, thickened gallbladder wall or hyperemia. Cholescintigraphy An ejection fraction of <33% (may be 35 to 40% depending on different protocols at different institutions) after 60 min is indicative of impaired gallbladder A diagnosis of acalculous cholecystitis is made when the gall bladder ejection fraction (GBEF) is <35-38%. Studies have shown that low GBEF is sensitive but not a specific indicator of gall bladder inflammation. The higher spectrum of gall bladder ejection fraction has largely remained unnoticed as it is considered normal. In people with normal gallbladders, the ejection fraction ranges between 35-75 percent.
