What is the diameter of a bile duct?
The mean diameter of the normal common duct was 4.1 mm. A common duct greater than 7 mm in diameter can be seen in (a) nonjaundiced patients with gallstones and/or pancreatitis, or (b) jaundiced patients with common duct obstruction by stone or tumor.
What is normal CBD diameter?
1.8mm to 5.9 mm
The normal range of CBD diameter was 1.8mm to 5.9 mm. However, 65% of the study participants had a common bile duct diameter of < 4 mm. The majority of the patients irrespective of the age group had the diameter which ranges from 2–3.9 mm. But, most subjects in the old age group had a CBD diameter ranges from 4–5.9mm.
What is CBD caliber?
The common bile duct (CBD) was measured in 600 ultrasound studies. In normal patients the mean width of the CBD increased from 2.8 mm in the age group 20 years or younger to 4.1 mm in patients 71 years of age or older. In presence of cholelithiasis the mean width of the CBD was 4.5 mm (range 2 to 15 mm).
How many mm is the common bile duct?
Conclusions: Our study shows that the normal size of the common bile duct is 4.16 mm. This is smaller than the size accepted by the literature and than the 4.88 mm in cholecystectomy patients.
How wide is the cystic duct?
The normal diameter of the cystic duct is variable, ranging from 1 to 5 mm. The cystic duct usually joins the extrahepatic bile duct approximately halfway between the porta hepatis and the ampulla of Vater.
What are the symptoms of dilated CBD?
People with biliary obstruction usually have:
- light-colored stools.
- dark urine.
- jaundice (yellowish eyes or skin)
- itching.
- pain in the upper right side of the abdomen.
- nausea.
- vomiting.
- weight loss.
What is the normal gallbladder wall thickness?
Patients were divided into four groups based on the degree of gallbladder wall thickness: normal (1-2 mm), mildly thickened (3-4 mm), moderately thickened (5-6 mm), and severely thickened (7 mm and above).
What is PV and CBD?
CBD: common bile duct; EUS: endoscopic ultrasound; PV: portal vein.
