Operative results of tumor enucleation method as minimized surgical treatment for small liver cancer patient with liver cirrhosis is reviewed. Over 3 years survivor counts 7 cases, and 5 is still alive, with a 4 years 6 months of longest survivor, and cummurated 4 years survival rate is 52%. Postoperative recurrence is seen in 9 patients. In 6 cases of this group, recuned tumor appeared in another segment from the site which had contained the primary tumor, while in 3 cases of it, recurrence was seen in the area clore to the cutting sunface. His to pathological examination of there 3 marginally recuned cases revealed the nature of tumor as in complate capsel formation or extra capurale invasion which suggests as the retaining cancer cells in surrounding unresected tissue. This fact strongly proclaims us that operative indication should he more serious to improve the radicality of whole tumor. We consider that the method of tumor enucleation should her performed only in tiny lesion less than 3cm in cliameter and has obvious capsel without extra capsurale invasion or any intra hepatic metastasis. For accomplischment to this purpose, real time US monitoring especially intra operative ultra sonography is very useful.
