Gallbladder and sphincter of Oddi motility disorders are well recognized. Gallbladder dyskinesia may be confirmed by the use of cholecystokinin, cholescintigraphy, and calculating the gallbladder ejection fraction. This investigation selects a group of patients who improve after cholecystectomy. Studies have evaluated the efficacy of sphincter of Oddi manometry and have shown it to be highly reproducible. Using manometry, reflexes that might influence sphincter of Oddi motility have been described.
