Liver cysts are a benign disease of the liver, which generally does not affect life expectancy, and surgical resection is recommended for liver cysts of 10cm. Most liver cysts are congenital liver cysts, which are benign lesions of the liver; they can also be caused by degenerative liver disease, which manifests as cystic enlargement of the liver, which can be easily detected during ultrasound examination. Liver cysts with a diameter of more than 10 centimeters are called giant liver cysts. Ultrasound-guided aspiration of the cyst can be used, and the cyst cavity can be closed by injecting an appropriate amount of anhydrous alcohol into the cyst cavity. This method is safe, accurate, less traumatic, quick recovery and less complications, and has become the first choice for many people; resection can also be considered for single giant cysts; partial hepatectomy can be considered for multiple cysts. It is recommended that patients with liver cysts go to regular hospitals to avoid delays in diagnosis and treatment.
