[Intrahepatic stone formation and hepatectomy].

In our hospital, we had experienced 3,036 cases of gallstones from January 1968 through December 1983, among which intrahepatic stone cases was 154, (5.1%). Intrahepatic stone formation is classified based on X-ray pictures, i.e., congenital intrahepatic cystic bile duct dilatation, for example, Caroli's disease. anomaly of the bile duct. acquired extrahepatic ductal stones. operation. Hepatectomy was performed in 49 of 154 intrahepatic ductal stone cases. We never experienced operative death. We should select operative methods, taking mode of formation into consideration. Hepatectomy for intrahepatic ductal stones was radical surgery and it shortened therapeutic period. Prognosis is good in 41 cases and poor in 6. In 2 among latter 6 cases, recurrence of stones was observed and in other 4 cases, residual stones and cholangitis were noticed. Two cases died, one due to hepatic abscess and the other another disease.
