Motor pattern of the sphincter of Oddi in patients with bilioenteric shunt: a manometric study.
An endoscopic biliary manometry was performed on 11 patients with a surgical bilioenteric shunt--choledochoduodenostomy--and no pressure gradient between common bile duct and duodenum. Basal pressure and frequency of the phasic waves of the sphincter of Oddi were significantly higher in these patients than in controls or in patients with retained common bile duct stones. These results suggest a functional adaptation of the sphincter of Oddi in an attempt to recover the normal pressure in the biliary tract.
