Full history/Diagnosis is available below
There was prompt contraction of the gallbladder following administration of 0.02 ug/k of sincalide by slow intravenous infusion. The calculated gallbladder ejection fraction was 50%. The sincalide infusion did not reproduce the patient's pain.
In this study, sincalide was administered to evaluate for chronic acalculus cholecystis. The normal response to sincalide argues against this disorder. However, the sensitivity and specificity of this "CCK HIDA" study is currently under debate in the literature.
