Aim. Based on the data, obtained during the spiral computed tomography, to determine the frequency of occurrence of different anatomical variants of the liver position in the abdominal cavity of the examined persons. Material and Methods. Computer tomograms of 205 people of both sexes of the youth and the first period of adulthood were analyzed. The examined persons in accordance with the classification of Voilence V. N., Medelyan A. I., Omelchenko V. M. (1965) were divided into 6 groups depending on the anatomical variant of the spatial orientation of the organ in the abdominal cavity relative to the frontal and sagittal planes. Results and Discussion. Liver displacement relative to the frontal plane of anterior (anteflexio) was determined in 34 people (16.5%); posterior (retroflexio) - in 13 people (6.4%). Displacement of the liver relative to the sagittal plane to the right (dextropositio) found in 54 of the examined persons (26.3%), while displacement of the liver to the left (sinistropositio) found in 13 patients (6.4%). The intermediate position of the liver is 67 people (32.7%). The combined liver displacement in both sagittal and frontal planes was revealed in 24 patients (11.7%). Conclusions. Taking into account the anatomical variability of the liver position in the abdominal cavity will allow to avoid errors in the interpretation of morphometric parameters of the organ, and will provide additional information to surgeons that can optimize the operational access to the liver.
