На компьютерных томограммах брюшной полости 75 детей и подростков, разделенных на 4 группы (период раннего детства, период первого детства, период второго детства, подростковый период), определены площади аксиальных срезов, высота и объем восходящей и нисходящей ободочных кишок. Полученные данные подвергнуты вариационно-статистической обработке.Результаты. Среднее значение показателя площадей аксиальных срезов восходящей ободочной кишки среди обследованных 1-й группы составило 7,0±0,4 см2 и увеличилось в 4-й группе до 11,0±0,6 см2 (p&lt;0,001). Среди девочек величина этого показателя нарастала с 7,0±1,1 см2 до 10,5±0,6 см2 (p=0,013), а среди мальчиков – с 7,0±0,5 см2 до 11,5±1,1 см2 (p&lt;0,001). У детей раннего детского возраста среднее значение объема восходящей ободочной кишки составило 41,5±3,3 см3 и увеличилось в 4-й группе до 118,4±6,7 см3 (p&lt;0,001). У девочек определено увеличение объема этого отдела с 39,9±6,8 см3 до 112,3±6,9 см3 (p&lt;0,001), а среди мальчиков – с 42,0±3,9 см3до 125,1±11,9 см3 (p&lt;0,001). Среднее значение показателя площади аксиальных срезов нисходящей ободочной кишки среди всех обследованных увеличилось от 1-й к 4-й группе от 2,5±0,2 см2 до 4,3±0,4 см2 (p=0,005), у девочек – от 2,4±0,2 см2 до 4,0±0,4 см2 (p=0,089), а у мальчиков – от 2,5±0,3 см2 до 4,6±0,8 см2 (p=0,030). Значение показателя объема нисходящей ободочной кишки увеличилось от 1-й к 4-й группе от 20,9±2,4 см3 до 60,4±7,2 см3 (p&lt;0,001), среди девочек – от 20,3±0,9 см3 до 56,2±7,5 см3 (p=0,017), а среди мальчиков – от 21,1±3,1 см3 до 65,0±12,9 см3 (p=0,001).Заключение. В результате проведенного исследования установлено, что половые различия морфометрических параметров восхо дящей и нисходящей ободочных кишок в пределах одной возрастной группы отсутствуют. Достоверное увеличение среднего значения площадей аксиальных срезов восходящей ободочной кишки в каждой возрастной группе в сравнении с предыдущей без деления по полу установлено лишь среди обследованных второго детского возраста в сравнении с детьми первого детского возраста с 8,0±0,4 см до 9,4±0,4 см (р=0,044), среди девочек – с 7,8±0,5 см до 9,7±0,6 см (р=0,032). Достоверное увеличение среднего значения площадей аксиальных срезов нисходящей ободочной кишки в каждой возрастной группе в сравнении с предыдущей не определено. Установлено достоверное увеличение показателя объема восходящей ободочной кишки среди девочек второго детского возраста по сравнению с обследованными первого детского возраста (р=0,003) и подросткового возраста по сравнению с детьми второго детского возраста (р=0,042), а среди мальчиков первого детского возраста по сравнению с периодом раннего детского возраста (р=0,019). Определено достоверное увеличение среднего значения объема нисходящей ободочной кишки в каждой возрастной группе в сравнении с предыдущей без деления по полу определено у детей второго детского периода в сравнении с обследованными первого детского периода с 26,4±2,4 см3 до 43,5±5,5 см3 (р=0,005), среди мальчиков – с 26,2±3,6 см3 до 48,8±10,2 см3 (р=0,027).</p></abstract><trans-abstract xml:lang="en"><p>Objective:To establish age and sex patterns of axial section areas and the volume of the ascending and descending colon in children and adolescents according to the data of intravital imaging.Methods: On computed tomograms of the abdominal cavity of 75 children and adolescents, divided into 4 groups (early childhood, first childhood, second childhood, adolescence), the areas of axial sections, the height and volume of the ascending and descending colon were determined. The obtained data were subjected to statistical variation processing.Results: The average value of the index of the areas of axial sections of the ascending colon among the examined patients of the 1st group was 7.0±0.4 cm2. It increased in the 4th group up to 11.0±0.6 cm2 (p&lt;0.001). The level of this indicator among girls increased from 7.0±1.1 cm2 to 10.5±0.6 cm2 (p=0.013), among boys it increased from 7.0±0.5 cm2 to 11.5±1.1 cm2 (p&lt;0.001). In children of early childhood, the average value of the volume of the ascending colon was 41.5±3.3 cm3. It increased in the 4th group up to 118.4±6.7 cm3 (p&lt;0.001). An increase in the recorded level of this section among girls was from 39.9±6.8 cm3 to 112.3±6.9 cm3 (p&lt;0.001), and among boys – from 42.0±3.9 cm3 to 125.1±11.9 cm3 (p&lt;0.001). The average level of the index of the area of axial sections of the descending colon among all examined increased from the 1st to the 4th group. It increased from 2.5±0.2 cm2 to 4.3±0.4 cm2 (p=0.005), in girls – from 2.4±0.2 cm2 to 4.0±0.4 cm2 (p=0.089), and in boys – from 2.5±0.3 cm2 to 4.6±0.8 cm2 (p=0.030). The value of the indicator of the volume of the descending colon increased from the 1st to the 4th group from 20.9±2.4 cm3 to 60.4±7.2 cm3 (p&lt;0.001), among girls – from 20.3±0.9 cm3 to 56.2±7.5 cm3 (p=0.017), and among boys – from 21.1±3.1 cm3 to 65.0±12.9 cm3 (p=0.001).Conclusions: As a result of the conducted research, it was found that there are no sex differences in the morphometric parameters of the ascending and descending colons within the same age group. A reliable increase in the average level of the areas of axial sections of the ascending colon in each age group in comparison with the previous one without dividing by sex was established only among the surveyed children of the second age group in comparison with children of the first age group from 8.0±0.4 cm to 9.4±0.4 cm (p=0.044), among girls – from 7.8±0.5 cm to 9.7±0.6 cm (p=0.032). A significant increase in the average value of the areas of axial sections of the descending colon in each age group in comparison with the previous one wasn’t determined. A significant increase in the indicator of the volume of the ascending colon was found among girls of the second childhood group compared with the examined children of the first age group (p=0.003) and adolescence compared with children of the second childhood group (p=0.042), and among boys of the first childhood group compared with the period of early childhood (p=0.019). A significant increase in the average value of the volume of the descending colon in each age group in comparison with the previous one was determined in children of the second childhood period in comparison with the examined children of the first period from 26.4±2.4 cm3 to 43.5±5.5 cm3 (p=0.005), among boys – from 26.2±3.6 cm3 to 48.8±10.2 cm3 (p=0.027).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ободочная кишка</kwd><kwd>компьютерная томография</kwd><kwd>дети</kwd><kwd>подростки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>colon</kwd><kwd>computed tomography</kwd><kwd>children</kwd><kwd>adolescents</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Маргорин Е.М., Альхимович Е.А.
