The hepatobiliary stone is one of the most common surgical disease in Korean population, and intrahepatic stone is found in 9-x22% of the biliary calculous disease in Korea. A retrospective clinical study was done in 25cases of intrahepatic stones who underwent operation in Ewha Womans University Hospital during from Jan. 1986 to Sept. 1990
The result obtained are follows:
1) The incidence of intrahepatic stones to all gall stones during the period was 12%.
2) The incidence of sex was slightly predominent in female than male with the ratio of 1 : 1.3. The peak age incidence was 4th decade, the mean age was 51.8years old.
3) Left intrahepatic duct stones were found in 9cases(36%), right intrahepatic duct stones were found in 4cases(16%), both intrahepatic dud stones were found in 12cases(48%), and primary intrahepatic duct stones were found in 4(16%)cases.
4) Subjective symptoms were RUQ pain, jaundice, and fever and chills.
5) The most valuable diagnostic methods were endoscopic retrograde cholangiopancreatogram(ERCP), percutaneous transhepatic cholangiogram(PTC), computed axial tomography(CT) and abdominal sonography.
6) Operative procedures underwent, left lobectomy and segmentectomy in 9cases, choledochojejunostomy or choledochoduodenostomy in 14cases.
7) Post operative complication was 3cases(12 % ) of subphrenic abscess, lcases(4 % ) of septicenmia and wound infection.
In conclusions, the valuable diagnostic methods of intrahepatic duct stones are FRCP, PTC, abdominal sonography and CT. The hepatic lobectomy or segmentedomy is the best procedure ~i for intrahepatic duct stones.
