Hepatic cysts are relatively common benign diseases of the liver, and can be classified as simple hepatic cysts, polycystic liver disease, and hepatic encapsulated cysts. In patients with hepatic cysts, the enlargement of the cysts to a certain extent and the compression of the adjacent organs may induce the patients to have uncomfortable symptoms such as fullness after eating, nausea, vomiting and vague pain in the right upper abdomen. Generally, the diagnosis can be clarified by abdominal ultrasound, CT and other examinations. Treatment varies according to different types: 1. Simple hepatic cyst: it may be caused by abnormal development of intrahepatic vagal bile duct during embryonic period, or it may be caused by local hyperplasia caused by intrahepatic bile duct disease during fetal period. There are also some simple liver cysts secondary to other diseases, such as inflammation, trauma, tumor, etc. Usually, patients with small and asymptomatic liver cysts do not require special clinical management, but only long-term follow-up and observation. If it is accompanied by other symptoms and the liver cyst is huge, it needs to be treated. In principle, it is recommended that hepatic cyst opening and debulking drainage is preferred, and sometimes it is necessary to consider hepatic resection or ultrasound-guided puncture and drainage in combination with the patient’s condition, physical condition and location of cystic lesions. 2. Treatment is mainly aimed at relieving symptoms, treating complications, protecting liver function and delaying disease progression. For small and scattered cysts with no symptoms, no special treatment is needed, and the growth of cysts should be observed regularly; for those large and showing symptoms of compression, they should be treated actively. The main treatment methods are liver cyst puncture and hepatic artery embolization surgery. For patients with end-stage liver failure, liver transplantation can be performed; 3. liver worm cysts: When tapeworm infection occurs, the eggs invade the blood and lymphatic circulation system through the intestine and enter the liver, lung and other tissues through the portal vein, developing into worm cysts. Clinical treatment is mainly to eliminate parasites, reduce morbidity and prevent recurrence. Anti-cestode drugs are commonly used to treat the disease, such as albendazole and other systemic treatments, which can slow down the development of the disease.
