Percussion pain in the liver area is actually a more obvious pain symptom in the patient when the liver is percussed. In this case, the indirect percussion method, in which the first and second knuckles of the middle finger of one hand are used as a percussion plate, and the end of the middle finger of the other hand is used as a percussion hammer to percuss on the trigger finger in a vertical direction, is valuable for diagnosing diseases such as hepatitis and liver abscesses. Diseases other than the liver, such as subdiaphragmatic abscess, may also cause symptoms of percussion pain in the liver area. Liver percussion is performed along the right midclavicular line, right midaxillary line and right scapular line from the lung area downward, that is, the abdomen. If the hepatic percussion pain is accompanied by enlargement of the hepatic turbinate, liver abscess, hepatitis or primary liver cancer should be considered. If percussion pain in the liver area is combined with a narrowing of the hepatic turbinate, acute liver necrosis and cirrhosis should be considered. Although subdiaphragmatic abscesses may present with percussive pain in the liver, the enlargement of the hepatic turbinate due to the subluxation of the lungs and elevation of the diaphragm, but not due to the enlargement of the liver, should be noted. The initial diagnosis of the disease can be made clinically by the relevant examination, i.e. percussion pain in the hepatic region.
