Numerical simulation on abdominal adhesion during physical palpation

Adhesion is hard to detect as the symptom is similar to some other abdominal problems such as appendicitis, diverculitis or endometriosis. They can be accurately diagnosed by invasive method. Non-invasive method is used to facilitate the detection of adhesion. The most common non-invasive method is...

description Adhesion is hard to detect as the symptom is similar to some other abdominal problems such as appendicitis, diverculitis or endometriosis. They can be accurately diagnosed by invasive method. Non-invasive method is used to facilitate the detection of adhesion.
