Liver cysts are relatively common benign diseases in clinical practice, congenital factors are more common, most of them have no clinical symptoms and are found incidentally during physical examination, most of them do not require treatment and only need regular observation, but patients with larger size or have produced obvious clinical symptoms should start active treatment. The best treatment includes: 1. For a single liver cyst less than 5 cm, if it is located in the liver parenchyma and does not cause compression to the major large blood vessels and bile ducts in the liver, without any clinical symptoms, it can be observed and it is recommended to review the ultrasound every year to understand its growth. If compression symptoms appear, such as epigastric fullness and pain, laparoscopic surgery is needed. 2. If it causes compression of large blood vessels or bile ducts in the liver, it needs to be seen in a regular medical institution, where a professional hepatobiliary surgeon can evaluate the condition and propose a treatment plan. Specific methods include the following: cyst puncture and aspiration, cyst windowing, cyst drainage, and cystectomy. Some cysts require partial removal of the liver. Patients suffering from liver cysts should not be overly worried and must go to the hepatobiliary surgery department of a regular hospital to avoid unnecessary panic.
