Under normal circumstances, liver cysts do not usually affect a person’s life and should be reviewed regularly. Liver cysts are benign tumors that grow slowly, so it is important to have regular annual ultrasound reviews to determine the growth rate and size of liver cysts. Large liver cysts may cause compression symptoms, resulting in loss of appetite, abdominal distension and pain, and can be treated with surgical resection. A part of liver cysts may rupture and develop peritonitis when they grow large, or produce abnormal liver function, or even lead to liver failure, which is the only condition that will affect the patient’s life expectancy, but this is very rare in clinical practice. For patients with liver cysts, it is recommended to consult the hepatobiliary surgery department of a regular hospital for follow-up examinations.
