Abstract
Although abdominal U/S is a good initial screening method for
detection of biliary tract disease, we sometimes encounter patients in
whom the only finding is dilatation of the common bile duct on U/S,
without specific biliary symptoms or jaundice. This study aimed to
evaluate the types of relation between the common bile duct
diameter and hyper bilirubinaemia.
Hundred and twenty six patients were included in this study.
The common bile duct diameter and the serum bilirubin were
measured. It was concluded that, there was a weak correlation
between the CBD diameter and serum bilirubin level (correlation
cofficent = 0316). The rise in serum bilirubin was found to be highly
related to the duration of the obstruction (P<0.001). 12.7% of the
study groups have a normal serum bilirubin inspite of dilated
common bile duct (56.25%) of them proved to have CBD stone
(P=0.993). Very high bilirubin level reflects malignant obstruction
rather than choledocholithiasis.
The age is shown to have no relation to the common bile duct
diameter (P-value= 0.904) as proved by this study. The serum
albumin is proved to have a significant relation to the serum
bilirubin (P=0.032), and low albumin level leads to significant rise in
the serum bilirubin, while, INR (although is found to be prolonged in
(41%)) has no such a relation.
