Computed Tomography in obstructive jaundice preponderance of dilated intrahepatic biliary channels in left lobe
Pak Postgrad Med J Dec 2000;11(4):129-31.
Services Hospital, Lahore

Purpose of Study: To establish that intrahepatic bile duct dilatation shown by computed tomography has a predilection for the left lobe. Materials and Methods: 50 patients with obviously dilated intrahepatic hiliary channels on CT were included in the study. Diluted oral contrast was given to them prior to the examination. Plain and post 1/V contrast scans were done. 10 mm and 5 mm slices (where necessary) were taken. The distribution of dilated hiliary channels within the liver was noted. The level of the biliary duct obstruction, portahepatis, mid or lower common bile duct was also judged. Results: Dilated biliary channels were seen within the left lobe of the liver in 42 out of 50 patients. As far as level of obstruction was concerned, in 34 of these 42 patients it was at the lower end of the common bile duct. Conclusion: Preponderance of dilated intrahepatic biliary channels in the left lobe in obstructive jaundice is an important finding to appreciate, which should not be mistaken as segmental intrahepatic biliary obstruction which is usually associated with an intrahepatic cause.
