Normal findings in oral cholecystography and normal response of the gallbladder to cholecystokinin are established in 200 normal controls. These include absence of right upper quadrant pain in 98.5%, absence of spasm of the gallbladder neck or cystic duct in 94%, absence of any spasm of the body of the gallbladder and of severe spasm in the fundus, a common bile duct diameter of 6 mm or less in those 182 that were visualized, and gallbladder size of less than 11 cm in length in about 97% and less than 4 cm in width in about 97%. If normal contraction occurs after cholecystokinin (or sincalide), an unusually large gallbladder is of no importance. Little or no gallbladder contraction in the presence of normal concentration is probably of no importance.
