Abstract：
:Cholecystectomy will not always relieve the abdominal symptoms of the patient with gallstones. The functional effects of gallbladder removal in a patient with a patent cystic duct are not known in detail. Studies of the function of the gallbladder and pancreas have suggested feedback mechanisms for the release of cholecystokinin (CCK). A disturbed regulation of CCK release after cholecystectomy might induce pancreaticobiliary and gastrointestinal dysfunctions. In our study the concentrations of CCK in plasma were measured in 17 patients with gallstones. The measurements were taken with gallbladders opacified at cholecystography and with patent cystic ducts at the operation, in the fasting state, and during stimulation before and 17 weeks after the cholecystectomy. The CCK assay used measures sulfated CCK-8, CCK-22, and CCK-33 with equimolar potency but neither nonsulfated CCK nor any gastrins. Emtobil (containing peanut oil and sorbitol) was used for peroral stimulation of the CCK release. The basal concentration of CCK was 4 pmol/L and rose five times during a "test meal." No significant differences were seen in fasting or stimulated concentrations of plasma CCK before and after the cholecystectomy. Thus cholecystectomy in gallstone patients with functioning gallbladders does not seem to influence the regulation of CCK release.
