Abstract
A method of manometric choledochography is described by which three types of choledochal pressure/filling curves could be obtained in patients undergoing cholecystectomy. This work provides evidence that biliary pressures are mainly a function of the choledochal sphincter in man and are largely independent of duodenal muscular activity. Reflux of contrast medium into the pancreatic duct is not associated with either obstructive pathology of the lower choledochus or biliary hypertension.
