Successes   of   surgical   hepatology  are   in  many   respects  caused   by  continuous improvement of  equipment of  liver resection. However   discussion   of  the  references containing the description of techniques of resections and necessary for carrying out these difficult  operations of  the  equipment, is complicated by a  variety  of  the  classification approaches used  by  various  authors when  the  same  intervention has  three  and  more various  names. At the  description of  liver resections of  different volumes  still there  is a terminological confusion. It is possible  to  call the  same  intervention «lobectomy», «an expanded hemihepatectomy», «treesegmentectomy» of that  is put in this concept though there  are  accurate anatomic definitions which  characterize a  certain  part  of  a  hepatic parenchyma.
