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.
MATERIALS AND METHODS: The diameter of the common bile duct was measured with sonography in 173 children aged 1 day to 13 years (mean, 6.0 years; median, 5.0 years) who were examined for reasons other Common bile duct measurements in an elderly population. Ultrasonography of the common bile duct was performed only in those patients with no subjective abdominal pain or icterus. Our results demonstrated a small although statistically significant increase in the caliber of the common bile duct with increasing age (60 years old or less, mean diameter 3.6 mm +/- 0.2mm, versus over 85 years old, mean Ultrasonographic Measurement of Normal Common Bile Duct ... Dec 05, 2014 · While the lower limit of common bile duct diameter among the normal subjects was 2.0 mm, the upper limit was found to be 7.9 mm. However, 95% of the study participants showed a common bile duct diameter of < 6 mm. [Table/Fig-2] shows the distribution of common bile duct diameter by age group.
And the common bile duct (CBD) diameter in people older than 51 years of age showed a significant difference compared to the subjects younger than 50 years of age (p<0.01). However, the degree of
Magnetic resonance cholangiopancreatography (MRCP) is a popular modality for evaluation of the biliary tract, yet there is no data on the normal common bile evaluated the normal parameters of CBD diameter with this diagnostic technique. For this Figure 2.

KEY WORDS: Common bile duct; Aging, common bile duct diameter. tive causes of jaundice, accurate standards for normal measurements must be available. Most authors accept a of thumb is to consider as normal a 4 mm mean duct diameter at age 40, a 5 mm mean on common bile duct diameter: a real-. Magnetic resonance cholangiopancreatography (MRCP) is a popular modality for evaluation of the biliary tract, yet there is no data on the normal common bile evaluated the normal parameters of CBD diameter with this diagnostic technique. For this Figure 2. Scatter diagram of variation of CBD size compared to age Conclusion: This study showed that normal CBD diameter in this environment The median age of the study population was 32.5 years with a range of 15-74 ultrasound the diameter of the common hepatic duct and the common bile duct in a series of 24 patients having patients had “normal” ducts 4-16 mo after upper limit of normal for the common bile duct of 7.0 mm in a population of 73 reported a mean duct diameter of 2.8 mm at age 20 years and 4.1 mm at 71 The common bile duct, sometimes abbreviated CBD, is a duct in the gastrointestinal tract of A diameter of more than 8 mm is regarded as abnormal dilatation and is a sign of cholestasis.
10 Mar 2011 My common bile duct was 17mm, distended gallbladder with wall thickening, no stones/sludge, normal blood (except elevated WBC).
The average common bile duct size was 4.88 mm (range: 2.6 to 7 mm). What is the normal size of the common bile duct - Answers However, there are reports were people with no hepatobilliary disease have a "normal" common bile duct size up to 10 mm. Also, there is a correlation between common bile duct diameter and age.
Several studies have shown that the average normal common bile duct diameter is 4 mm at age 40, and 5 mm at age 50 and 8 mm at age 80 [4,9,11,12]. Standardization of common bile duct size using ultrasound ... Current guidelines are based upon adult values for normal CBD size , , . We propose using three groups defined above in order simplify the age-based CBD size determined in our population.
In conclusion, our study shows that the average CBD diameter of the Taiwanese population measured by MRCP is 4.6 mm, with an upper limit of 10.5 mm. CBD diameter is significantly larger in patients older than 65 years of age, and increases proportionally by age for each subsequent decade of life. Is Age Associated with Size of Adult Extrahepatic Bile ... Effects of age and cholecystectomy on common bile duct diameter as measured by endoscopic ultrasonography 18 August 2012 | Surgical Endoscopy, Vol. 27, No. 1 The diameter of the common bile duct in an asymptomatic Taiwanese population: Measurement by magnetic resonance cholangiopancreatography What is the upper limit of normal for the common bile duct ...
These relationships are, however, controversial and based mainly on old studies and methodologies. Our objective is to evaluate the relationship between age, cholecystectomy, and other clinical factors and CBD diameter, as measured by endoscopic ultrasound (EUS). We carried out a … The diameter of the common bile duct in an asymptomatic ... In conclusion, our study shows that the average CBD diameter of the Taiwanese population measured by MRCP is 4.6 mm, with an upper limit of 10.5 mm. CBD diameter is significantly larger in patients older than 65 years of age, and increases proportionally by age for each subsequent decade of life.
