If the patient’s urinary routine results indicate that the patient has high urinary bilirubin, consider whether the patient has obstructive jaundice. In this case, the patient should have a blood test for liver function to see if the total bilirubin is higher than 34.2 μmol/L, and if direct bilirubin is predominantly elevated, and if alkaline phosphatase and GGT are also elevated in the liver function. If the results of these tests are positive, the patient should have an ultrasound of the upper abdomen and an MRI of the upper abdomen to determine the cause of biliary obstruction, whether the obstruction is caused by stones, tumor disease of the bile ducts, or tumor compression of the pancreas. For example, in the case of obstructive jaundice caused by bile duct stones, in addition to active hepatoprotective treatment, the patient should also undergo ERCP treatment, followed by removal of the common bile duct stones under ERCP and placement of a nasobiliary duct for drainage. If the obstructive jaundice is caused by tumor disease in the bile duct or pancreas, surgical treatment should be considered as soon as possible.
