Because pancreatitis can cause damage to liver function, with elevated transaminases and elevated bilirubin, liver function should be checked to understand the severity of liver damage. The liver function is also checked to rule out the presence of primary liver disease, and the specific medications used to treat pancreatitis should be selected based on the results of the liver function, and liver-protective medications may be required if necessary. For patients with chronic pancreatitis, the main clinical manifestations are abdominal pain, diarrhea, wasting and jaundice, so it is necessary to routinely identify with liver diseases, which can also cause the above symptoms, so liver function tests are required. In addition, blood routine, coagulation function, blood transfusion four and other related tests are also needed to find out the specific body lesions.
