based on the results of gallbladder emptying in response to endogenous and exogenous cck , four subgroups of gallstone patients were identified : ( 1 ) a group ( n = 7 ) with normal gallbladder sensitivity to cck , ( 2 ) a group ( n = 6 ) with significantly increased gallbladder sensitivity to cck , ( 3 ) a group ( n = 6 ) with impaired gallbladder emptying after corn oil due to a significantly reduced endogenous cck secretion but with normal gallbladder sensitivity to cck , and ( 4 ) one patient whose gallbladder was unresponsive to cck and was found to have chronic cholecystitis at surgery .
