Cholescintigraphy was performed on 89 subjects with gallstones and related diseases and 12 normal subjects as controls, using 99mTc(p-Butyl)IDA. Analytical studies were done on the influence of gallstones on the motor function of biliary system. The results were as follows.1) Gallstones remarkably influenced the motor function of not only the gallbladder but also the distal common bile duct, and especially influenced the contraction of the gallbladder.2) Both the gallbladder and the Oddi sphincter gained tonus with the expansion of stones in cholecystolithiasis.3) It was found that stenosis of distal common bile ducts was positively correlated to both expansion of stones and duration time of pains from common bile duct stones.4) Cholecystitis resulted in poor contraction of the gallbladder and increasing resistance to the bile flow by the distal common bile duct in acute stages.5) There existed a proportional relation between the tonus of the gallbladder and that of the Oddi's sphincter in patients with gallstones and related diseases.
