The normal diameter of the common bile duct is variable, but a diameter of greater than 7 mm is generally indicative of bile duct obstruction Is Age Associated with Size of Adult Extrahepatic Bile ... PURPOSE: To determine if the size of the extrahepatic bile duct increases with age in adults. MATERIALS AND METHODS: A total of 258 consecutive patients 18 years and older, without known biliary or pancreatic disease, who were fasting to undergo routine abdominal sonography were examined. The transverse and anteroposterior dimensions of the extrahepatic bile duct were measured proximally at Ultrasound of the Extrahepatic Bile Duct Ultrasound of the Extrahepatic Bile Duct Issues of Size Mindy M. Horrow, MD, FACR Abstract: Ultrasound is a pivotal study for evaluation of the biliary tree. In particular, the size of the extrahepatic bile duct is a critical measurement and has been a contentious issue since the early days of diagnostic ultrasound.
