Effect of hepatic and celiac vagal stimulation on common bile-duct pressure

Abstract

Bipolar stimulating electrodes were placed on the hepatic and celiac vagi of 6 dogs. The gallbladder was removed and the cystic duct cannulated with an 8 F infant feeding tube, the external end of which was attached to a specially made metal plug. Experiments were then performed on the dogs both when conscious and fasting. No change in common duct pressure was recorded in response to electrical stimulation of these vagal branches in these dogs, as noted in 209 separate stimulations using various combinations of voltage, frequency and duration. Flow rate did not change as noted with a drop counter during stimulations in 11 experiments.
