The methodology of research right iliac region in children with suspected acute appendicitis is graded compression technique. He is to put pressure line sensor to the anterior abdominal wall at the point of maximum tenderness – for leveling artifacts associated with the presence of gas in the terminal ileum and cecum dome, as well as to minimize the distance between the skin and the appendix. That allows the use of a sensor with high resolution.
Compression should be the most gentle, given the severity of the child’s negative reaction to pain, good imaging capabilities with ultrasound in children, small depth “area of interest”, as well as a possible shift of the target organ of the ultrasound slice. In some cases, the surface location of the inflamed appendix is a need for compression generally disappears. In addition to the research area of maximum tenderness less sensitive areas are also examined to detect changes in periappendikulyar – structures ileitis, tiflita, omentita, mesadenitis – ha mezhpetlevyh infiltrates and abscesses.
Ultrasound anatomy of the right iliac region in complicated forms of acute appendicitis can be significantly “distorted”, which requires a thorough investigation of this area by obtaining the maximum number of linear cuts. If the diagnosis remains unclear, it is necessary to repeat the test after 20 minutes. In some cases (mainly at small timing of onset and if the patient’s condition allows) sonography is repeated after a few hours. In addition, prolonged compression of the right iliac region causes a spasm of the cecum, which improves the assessment structures ileocecal region. The duration of one study is usually 10-15 minutes. Uncomplicated acute appendicitis in ehotraficheskoy based diagnosis of acute appendicitis is direct visualization of inflammatory changes of the appendix.
