Hepatic cysts, most of which are benign lesions of the liver, are congenital liver cysts and can also be caused by degenerative disease of the liver. It is manifested by a cystic enlargement inside the liver, which is easily detected during ultrasound examination. This is the type of liver cyst we usually refer to. Of course, liver cysts can also be caused by tumors, liver parasites, and inflammatory diseases. These can be identified by ultrasound and other tests. After ruling out the case of liver cysts caused by tumors, liver parasitosis, and inflammation, if there is no discomfort and there are no complications, no treatment is needed. This is because generally the cysts contain only some clear liquid and rarely rupture, and even if they do, the liquid flowing into the abdominal cavity is not harmful to human body. Moreover, cysts are usually not cancerous, do not damage liver function, and do not affect normal life. Therefore, it only needs regular review in hospital and 1-2 ultrasound times a year. Since there is no special medicine to eliminate liver cysts, it is also not necessary to take medicine to treat them. However, if the cyst is larger than 5 cm and continues to increase in size, showing symptoms of compression and causing discomfort, you can choose to treat the cyst by ultrasound-guided cyst puncture and aspiration followed by injection of anhydrous alcohol into the cyst, or you can take laparoscopic cystotomy.
