title: Effects of sphincter of Oddi bypass on bile acid metabolism in fed and fasted intact and cholecystectomized dogs.
abstract: The effects of cholecystectomy and sphincter of Oddi bypass on bile acid (BA) metabolism in dogs have been studied. Cholecystectomy and sphincter bypass decreased the BA pool half-life and increased the percent of taurodeoxycholic acid in the pool. A 48-hour fast had no effect on total BA pool size of intact and intact sphincter-of-Oddi-bypassed dogs but caused a marked decrease in cholecystectomized dogs. It was concluded that while the sphincter of Oddi is unnecessary to maintain bile acid pool size in fasting dogs, the gallbladder is. Alimentation is necessary to maintain pool size in cholecystectomized dogs.
