Common Bile Duct Pressure and Oddi Sphincter Pressure in Patients with Common Bile Duct Stones with and without Juxta-ampullar Diverticula of the Duodenum

Abstract

Resting common bile duct pressure and Oddi sphincter pressure were measured in 16 patients with common bile duct stones, 8 having in addition a juxta-ampullar diverticulum. Pressure measurements were performed with an infused catheter introduced through an endoscope under direct vision. No significant differences in fasting common bile duct pressures were observed between the 2 groups. The Oddi sphincter had a phasic activity, and the peak pressure was similar in both groups.
