Ultrasonic research of organs of the hepatobiliary system


  • Ultrasonography of the abdominal cavity in children
  • Ultrasound scan of the hepatobiliary sphere – the most common radiation survey. Such frequent use is associated with the availability, simplicity of procedure and at the same time diagnostic accuracy, non-invasive, safety and security. Because ultrasound scanning does not apply ionizing radiation, it is used in children and pregnant women.

    Indications for ultrasound of the hepatobiliary system

    • Pain in the abdomen.
    • Suspected biliary colic.
    • Jaundice.
    • Increase in abdominal cavity detected by palpation.
    • Suspected tumor in the abdomen.
    • A history of pathology of the hepatobiliary system.
    • Portal hypertension etc.

    The technique of the ultrasound

    Ultrasound is carried out according to standard methods. The duration of this study averaged twenty to thirty minutes. For better visualization of organs, the doctor may ask the examinee to hold his breath for a deep breath, roll over to one side. Sometimes, when individual characteristics of patients, for example, if the spleen is very high in the abdominal cavity, it is necessary to scan in a sitting position or even standing.

    In the process of echography of the liver are evaluated by position, size, shape of the test body, its echogenicity, structure, pathological education. Examine the condition of the bile duct, blood flow (as in on and identified the hearth).

    The examination of the gallbladder measured the thickness of the body wall, pay attention to the character of the bile, foreign objects in the lumen (calculi). Estimate the size of the common bile duct (common bile duct), an ultrasonic signal content.

    Ultrasound examination of the pancreas study the size, the shape of the body, assess the homogeneity of the structure and echogenicity of the parenchyma, the presence of zones of altered ULTRASOUND signal, as the ductless glands.

    When scanning of the spleen in addition to the standard parameters, study of the portal, splenic and inferior caval veins.

    After the procedure the Protocol is issued with the conclusion of ultrasound.

    The results of the scan, the doctor of ultrasound diagnostics does not make the diagnosis! The diagnosis sets the attending doctor (in view of the clinical picture, data of tool, laboratory and radiological examination).

    How to prepare for the study

    To conduct ULTRASOUND scan of the hepatobiliary system requires special training, which depends on quality and informativeness of the study. The fact that the passage of ultrasonic waves prevents the air and the fat, so to properly prepare for the ultrasound, it is necessary to remove excess air contained in the intestines. This is especially important for obese patients.

    The exception is an emergency pathology, in these cases the preparation is not carried out.

    Basic principles of preparation for an ultrasound

    • To comply with uncindery diet for at least three days before the intended survey, and also to eliminate foods that trigger flatulence: vegetables, fruits, sodas, juices, rye bread.
    • The last meal before the test should be for ten to twelve hours (that is, the method is performed on an empty stomach).
    • If the patient has a flatulence, two days before the procedure, you must use a carminative (for example, Drops adults and children over six years recommended doses: two to three capsules after meals and at night; in the day of the ultrasound this drug do not need to take).

    Ultrasonography of the abdominal cavity in children

    In recent times there is a persistent increase in diseases of the hepatobiliary system in children, due to many reasons. For early detection of this pathology in children and adequate differential diagnosis of brain lesions requires a modern, non-invasive, safe and accessible imaging modality, which is ultrasonography.

    Ultrasound should be carried out when the first symptoms of diseases of the digestive system in children. The methodology of the study and preparation for the procedure in children are the same as in adults. Often the visualization of internal organs in children better due to the smaller amount of adipose tissue.

    I would like to note that the ultrasonic method is very important in the diagnosis of diseases of the digestive system in both adults and children.

    Don’t forget that before the planned study required a thorough preparation of the patient for the study.
