If the cyst on the left liver is small, less than 10 cm, or if the patient has no obvious symptoms, it can be temporarily observed and no special treatment is needed. If the cyst on the left liver is relatively large or if it produces compression symptoms on the surrounding stomach, surgery is also recommended. If the cyst is protruding from the surface of the liver, a laparoscopic window drainage can be performed. If the cyst is located inside the left lobe of the liver, the left half of the liver can be removed if the left lobe is completely destroyed. Liver cysts are benign lesions that can grow in any part of the liver, and most of them do not require special treatment unless they are large and have a compressive effect on the surrounding tissues and organs, which can be treated surgically.
