Abstract
A 54-year-old male complaining of jaundice and right hypochondralgia was admitted to our hospital. Percutaneous transhepatic cholangioscopy (PTCS) was performed on suspicion of intrahepa tic stones.
The stones were found in the right anterior inferior branch (B5) and left caudate branch (B1ls). All stones were completely removed by PTCS. Then, cholecystectomy was performed because of gallbladder stones. The analysis of composition revelaed 98% cholesterol in intrahepatic stones, on the other hand,70% cholesterol and 30% calcium carbonate in gallbladder stones. Intrahepatic stones were considered to be primary intrahepatic cholesterol stones by the following reasons. First, the composition between intrahepatic stones and gallbladder stones were different. Second, segmental cylindrical or cystic dilatation of intrahepatic bile ducts were r ecognized. The entrance of B5 was slightly stenotic and cylindrical dilatation of the dust in which the stones existed. Cystic dilatation was seen in B1ls. PTCS was useful for the diagnosis and treatment of intrahepatic stone.
