Trivus symptom is a sound phenomenon that occurs during percussion of the lungs and indicates the presence of subphrenic abscesses. This can be a very important diagnostic sign, which allows us to identify the presence of infection in the subdiaphragmatic space.
During percussion of the abdominal cavity, when the doctor places his palm on the patient's stomach, sounds can be heard that reflect the condition of the internal organs. In the presence of a subphrenic abscess, a small strip of clear pulmonary sound can be detected between the heart and the underlying area of dull percussion. This sound occurs because the subphrenic abscess creates a space in which air can move freely.
The trivus sign can be detected not only by percussion of the abdomen, but also by other studies, such as ultrasound or MRI. This allows the doctor to determine the location and size of the subphrenic abscess and prescribe appropriate treatment.
It is important to note that detection of the trivus symptom is not the only criterion for diagnosing a subdiaphragmatic abscess. To confirm the diagnosis, additional studies and tests are necessary. However, this symptom can serve as an important indicator of the presence of infection and require further examination and treatment.
