The specific treatment process is as follows The specific treatment process is as follows: 1. Detailed laboratory tests are performed to determine whether the cause of bilirubin elevation is prehepatic, hepatic or posthepatic. 2, prehepatic bilirubin elevation is mainly to actively treat the primary disease such as hemolytic disease and anemia. 3, hepatic and post-hepatic bilirubin elevation is determined by detailed medical history, such as history of medication, history of alcohol consumption, history of pregnancy and history of liver disease, combined with laboratory tests and liver ultrasound, CT, MRI, ERCP (transendoscopic retrograde cholangiopancreatography), PTC (percutaneous hepatic percutaneous cholangiography), liver tissue biopsy, laparoscopy and adrenocorticotropic hormone treatment experiment to determine the cause, so as to provide symptomatic treatment.
