[Effect of vagotomy on the motor function of the gallbladder]

409 roentgenological studies were performed, using the method of serial cholecystography prior to and after giving a bile-expelling breakfast, in 102 patients with duodenal ulcer, in 174 patients after trunk and in 89 patients after selective vagotomy with pyloroplasty. It was found that the volume of the gallbladder beyond the digestion act following trunk vagotomy is increased by 20%, on the average, by 30%--after selective vagotomy. It is concluded that there are no principal differences in the influence of trunk and selcetive vagotomy on the tonus and motility of the gallbladder.
