title: [Asymptomatic or paucisymptomatic CBD dilatation on US after cholecystectomy: management].
abstract: In western countries, 10-15% of the population has gallbladder stones with 46,000 cholecystectomies performed in France in 2003. So, daily ultrasonography of the abdomen performed in patients without gallbladder is a routine exam. However, identification of an enlarged common bile duct is frequent and the normal nature of this finding remains uncertain. The purpose of this article is to perform a literature review of the impact of cholecystectomy on the diameter of the common bile duct. Furthermore, it is important not to dismiss common bile duct dilatation after cholecystectomy because it may be the result of post operative complication or secondary to a congenital disease of bile duct.
