Cholecystokinin (CCK) functional cholescintigraphic findings in patients with a partial cystic duct obstruction - the cystic duct syndrome (CDS)
Fourteen patients (pts.) with a CDS underwent CCK functional cholescintigraphy (FC). All pts. presented with persistent post-prandial right upper quadrant pain and biliary colic. None had an abnormal OCG, gallbladder (GB) ultrasound exam or upper G.I. series. All had macro- or microscopically abnormal cystic ducts (5 fibrotic, 7 elongated and narrow, 2 kinked) with (12) or without (2) concomitant chronic cholecystitis. Each pt. (NPO after 12 A.M.) received 5 mCi of technetium (TC)-99m Hepatolite. When the GB max. filled, .02 ug/kg CCK was administered (3 min.) I.V. Background corrected GBEFs were determined q.5 min. x 4 by ratioing the pre-CCK GB cts. minus post-CCK GB cts. to pre-CCK GB cts. GB EFRs were: 3 (12%), 2 (17%), and 1 each 0%, 1.3%, 3%, 4%, 6%, 11%, 14%, 18.5% and 22%. No pt. with a partially occluded cystic duct with or without concomitant chronic cholecystitis had an ejection fraction that exceeded 22%. In an appropriate clinical setting, a low ejection fraction response to CCK should alert the physician to the presence of either chronic acalculous cholecystitis, CDS, or the combination of both.
