Intraluminal pressure recording from the human sphincter of Oddi

In this study we recorded intraluminal pressure from the human sphincter of Oddi during ERCP examination and determined the effect of enteric hormones on sphincter of Oddi motor function. Studies were obtained in 26 patients who had no demonstrable evidence of pancreaticobiliary disease. After cannulation of the common bile duct (CBD) or pancreatic duct (PD), pressure measurements were made across the sphincter of Oddi (SO) during 1-2 mm...
