Ultrasonic Characteristics of the Structure of the Liver Capsule in Healthy Children of Different Ages

Abstract

Ultrasound examination (ultrasound) takes the first place first among visual methods for analyzing the state of the liver parenchyma. Despite the improvement of ultrasound technology, it does not provide the necessary diagnostic accuracy in determining the stages of liver fibrosis. In this regard, it is necessary to search for additional diagnostic criteria to judge the state of the liver tissue and its superficial structures, primarily liver capsules.Materials and methods: the state of the liver capsule was assessed in 73 children of four age groups (2-18 years) without pathological changes in the hepatobiliary system, which were performed by ultrasound of the abdominal organs during preventive examinations. The structure of the capsule of the liver and visceral peritoneum was evaluated. Results. Direct dependence of the thickness of the liver capsule on the age of children was established (rs = 0.577, p = 0.0000). The capsule and visceral peritoneum represented a single and even echogenic structure (95.9%). Stratification of the leaves was detected in 8 children. A change in the shape of the edge of the right lobe of the liver was observed in 4 children. An increase in the severity of subcapsular blood flow in the liver was not detected in any healthy child.
