Functional reserve in benign volumetric lesions

: For evaluation of functional status of hepatocytes in patients with benign volumetric growths of the liver (BVGL) of various genesis the authors performed radionuclide investigation with the use of Tc99m. At the same time the terms of maximal accumulation of the preparation Tmax' the period of half elimination from the liver (T1/2) and the time of entering of the drug into the bowel (T bowel) were evaluated. Basing on the results of the analysis of clinical examinations in 67 patients before and after operations (51 patients with BVGL and 16 patients of control group), the authors have revealed correlation between the size, site disposition of volumetric growth and function of hepatocytes of intact parenchyma of the liver. The results have evidenced that the rate of decrease in functional values of the liver in groups of patients with BVGL 5 cm in diameter significantly (p 5 cm in d.), location and position of the growth in the organ, as well as adequately evaluate effectiveness of surgical intervention.
