title: Intraoperative pressure measurements of the choledochoduodenal junction, common bile duct, cysticocholedochal junction and gallbladder in humans.
abstract: With the use of the perfused system for manometry, the resting pressure profile in the biliary tract system was investigated during operation in 15 patients with gallstones. Resting intraluminal pressure of the gallbladder was lower than the pressure in the common bile duct. At the level of the choledochoduodenal junction, a sphincter with phasic activity was demonstrated. A second high pressure zone was observed at the cysticocholedochal junction without phasic activity.
