Treatment of small cysts in the right lobe of the liver usually depends on the size of the cyst, where it is growing, and whether there are any other complications. Often no treatment is needed, and if the cyst is large it can be treated surgically. Liver cysts are caused by disorders of embryonic development of the intrahepatic bile ducts, or they may result from long-term degenerative disease. Liver cysts can be single or multiple. If the liver cysts are relatively small and the patient has no uncomfortable symptoms, intervention is usually not required and regular review is sufficient. If the liver cysts are large, around 10 cm or more, and have symptoms of pressure on some of the surrounding tissues and organs, surgical treatment can be performed. Surgical treatment: 1. Cyst aspiration/intracapsular injection of sclerosing agent (e.g. anhydrous alcohol): it is suitable for patients with superficial lesions or those who do not tolerate surgery, but if the cyst wall is thicker or the cystic cavity is larger in size, complete sclerosis is often not possible, and so the clinical condition is prone to recurrence. 2. Cyst decortication: resection of part of the cystic cavity, so that the cystic cavity is connected to the abdominal cavity, the postoperative effect is good, and the risk of recurrence is also low. Doctors usually do not completely remove or destroy the remaining cystic cavity so as not to damage the liver tissue and cause complications, so even if there is fluid secretion from the cystic wall in the future, it will be absorbed by the abdominal cavity and will not lead to adverse effects. 3. Cystectomy: It is suitable for cysts located at the edge of the liver or protruding in the form of a tip, and can be completely removed. Patients with small cysts in the right lobe of the liver need to go to regular hospitals as soon as possible.
