 With the advent of real time linear scanner, the normal as well as dilated biliary tract can been seen regularly. In order to evaluate the bile duct disease with or without jaundice, electronic linear scanning was used for the delineation of extrahepatic bile duct and the comparative studies with ERC or PTC were undertaken. The patients with duct 4 mm or less had no bile duct disease, except cholecystolithiasis, whereas those with duct larger than 4 mm, had bile duct disease in 67% of them. Bile duct disease was found in all cases with duct larger than 12 mm, regardless of jaundice.
 The present studies suggested that when the extrahepatic bile duct with larger than 4 mm in its diameter, was found by ultrasound, ERC or PTC should be performed to examine the cause of its dilation.
