First of all, for multiple cysts in the liver, patients should check upper abdominal ultrasound or upper abdominal CT scan, and check tumor markers, methemoglobin, etc. to exclude the possibility of metastatic tumor, primary tumor, liver encapsulation disease, liver abscess, etc. in the liver. If the patient excludes other diseases and the diagnosis of liver cyst is confirmed, the upper abdominal ultrasound should be reviewed regularly, every six months or one year, to see the change of the diameter of the liver cyst. If the patient’s liver cyst is less than 5cm in diameter, the patient is not recommended to be treated at this time and can choose to continue to review. If the patient’s liver cyst is more than 5 cm in diameter and has certain symptoms, the patient can undergo liver cyst puncture and drainage or surgical treatment. Ultrasound-guided percutaneous transhepatic liver cyst aspiration and drainage. After the cyst fluid is drained, the cyst wall can be destroyed by injecting anhydrous alcohol and other drugs through the catheter and the catheter can be removed, but there is a certain complication rate and the possibility of recurrence. Alternatively, laparoscopic decortication and drainage of liver cysts or hepatectomy can be chosen, which has a relatively low recurrence rate.
