Abstract
The aim of the study was to establish age- and gender-related patterns of liver topography in children and adolescents based on intravital visualization data for use in determining the skeletotopy of abdominal organs.
Material and methods. Abdominal computed tomograms of 88 children and adolescents without visible pathology of the abdominal organs were analyzed. The subjects were divided into 4 age groups: periods of early, first and second childhood, and adolescence. The study was performed on 16-slice computed tomographs to determine the distance from the liver to the body surface, adjacent organs and anatomical structures of the abdomen, and skeletotopy. The obtained data were subjected to variational statistical processing to determine the median, the values of the 25th–75th percentiles, and the reliability of differences according to the Mann – Whitney U criterion.
Results and discussion. A statistically significant increase in the distance from the liver to the transverse colon, loops of the jejunum and ileum, abdominal aorta and spleen and a decrease in the distance from the liver to the duodenum from early childhood to adolescence were established. Skeletotopically, a tendency towards a lower location of the liver was determined with age. The right lobe of the liver in most cases was located between Th VIII and LIII–LIV in those examined in early childhood, and between ThX and LIV in adolescents. The left lobe of the liver in most cases was located between Th IX and LI–LII in early childhood, and between ThX–ThXI and LII–LIII in adolescence. The porta hepatis was located at the level of ThXII in early childhood and at the level of ThXII–LI in adolescence. The distance between the liver and the body surface statistically significantly increased along all lines from early childhood to adolescence. Reliable differences between the indicators of girls and boys of the same age group were established among adolescents along the left middle axillary, left scapular, right scapular and right middle axillary lines.
Conclusions. The article presents the topographic and anatomical characteristics of the liver in children and adolescents and establishes patterns of change taking into account the gender and age of the subjects.
