The common bile duct (CBD), which is sometimes simply known as the bile duct, is formed by the union of the cystic duct and common hepatic duct. Gross anatomy The CBD is approximately 8 cm long and usually <6 mm wide in diameter but this can b...


Various authors report different "normal" ranges for the diameter of the common bile duct. The consensus is that most people have a common bile duct diameter of around 5mm, +/- 1 mm.


The common bile duct, sometimes abbreviated CBD, is a duct in the gastrointestinal tract of organisms that have a gall bladder. It is formed by the union of the common hepatic duct and the cystic duct (from the gall bladder). It is later joined by the pancreatic duct to form the ampulla of Vater.


The size of the common bile duct is a predictor of biliary obstruction and it’s measurement is therefore an important component in the evaluation of the biliary system. Availability of normal measurements of the common bile duct would help to distinguish obstructive from non-obstructive causes of jaundice.


Common Bile duct is part of the “plumbing” that drains the secretion of the liver (bile) into small bowel (duodenum). The size of the common bile duct, if dilated, may suggest a blockage downstream.


A new sonographic technique for demonstration of the common bile duct is described in a prospective study of 200 patients. The mean diameter of the normal common duct was 4.1 mm. A common duct grea...


Actually the normal width of the common bile duct varies with age, for example, at age 20 the AVERAGE bile duct size is about 2.8 mm in width and in a person who is about 40 years of age, the size increases to 4.1 mm and it can even increase in size in patients who are older.


Whenever there is blockage or obstruction in bile duct, it enlarges in it size or dilates. The first symptom you may notice is pale colored stool and dark urine if bile duct is blocked, if the blockage progresses further it causes yellow discoloration of your eyes and skin. ...

Dilated bile duct is commonly seen in clinical practice and usually represents an obstructive lesion limiting the flow of bile. The evaluation of dilated bile duct is aimed to diagnose and treat the obstructive lesion. The clinical approach therefore requires (i) definition of normal limits of bile duct size (ii) predictive markers


Choledocholithiasis (also called bile duct stones or gallstones in the bile duct) is the presence of a gallstone in the common bile duct. Gallstones usually form in your gallbladder.
