Abstract

The intrahepatic duct stones are prevalent in East Asia and pose serious health problem because of the frequent recurrence and often associated suppurative cholangitis. Accurate diagnosis and localization of intrahepatic duct stones are essential to good prognosis and selection of adequate therapeutic methods. We studied 112 cases of intrahepatic duct stones diagnosed with ultrasound and confirmed by operation or other radiologicstudies for recent 3 years from May 1986 to May 1989 at Department of Radiology, National Medical Center, andanalysed ultrasonographic findings. The results were as follows; 1. Among 112 cases, 73(65%) were female, 39(35%) were male with predominancy in 5th decade. 2. The most common location of intrahepatic duct stones was left intrahepatic duct in 48 cases(43%), followed by right intrahepatic duct in 42 cases (37.5%) and both intrahepatic ducts in 22 cases(19.5%). In respect of segmental distribution, left lateral segment is the most common location(53 cases, 34%), followed by right posterior segment (43 cases, 27%). 3. Ultrasonographic findings were asfollows; Nodular pattern is the most common (59 cases,53%), followed by tubular or linear impacted pattern (23cases, 20%), irregular heterogenous conglomerated mass(13 cases, 12%), smooth homogenous single mass(10 cases, 9%)and mixed (7 cases, 6%) in orders. Ductal dilatations were classified by diffuse dilatation (16 cases, 14%). localized dilatation(50 cases, 45%) and no dilatation (46 cases, 41%). Many of the tubular impacted stones showedno ductal dilatation and single mass showed ductal dilatations in all cases. 4. In 53 cases (47%), combined extrahepatic duct stones were present. 5. As associated findings, liver cirrhosis in 11 cases (10%), cholangitisin 9 cases(8%), cholecystitis in 7 cases(6%), hepatic and pericholangitic abscess in 3 cases(3%) and CBD cancer,GB cancer, acute pancreatitis in 2 cases (2%) respectively.
