Despite the recent improvement in the surgical treatment ofintrahepatic cholelithiasis,inadequate correction of the concomitantbiliary tract stricture remains to be the major factor of therapeuticfailure.Proper management of both the stone and stricture are twoinseparable aspects of a problem.Today surgeons are in need of aseries of effective operative procedures to accomplish this purpose.In order to evaluate the different procedures used in this instituteon the basis of their long-term results,a retrospective study of 464cases of intrahepatic cholelithiasis surgically treated during a periodfrom 1963 to 1981 was carried out.Internal entero-biliary drai-nage is considered as a major approach in the surgical treatment ofintrahepatic cholelithiasis,but the result of choledochoduodenostomyis far from satisfactory since it brings about a lot of series sequelae,some of which are even disastrous.To the late cases complicatedwith portal hypertension,staged operation has proved to be imperative.11 of the 14 late cases were thus saved.The most difficult problemin the treatment of intrahepatic lithiasis at present is the right lobelesions especially those involving the second-order branches of hepa-tic ducts.The operative procedure the author used to manage thiscondition was introduced and discussed.
